Multicenter CT Image-Based Anatomic Assessment of Patients with Aortoiliac Aneurysm Undergoing Endovascular Repair with Iliac Branch Devices. Ann Vasc Surg 2024; 108:484-497. [PMID: 39009130 DOI: 10.1016/j.avsg.2024.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 04/29/2024] [Accepted: 05/02/2024] [Indexed: 07/17/2024]
Abstract
BACKGROUND The Global Iliac Branch Study (NCT05607277) is an international, multicenter, retrospective cohort study of anatomic predictors of adverse iliac events (AIEs) in aortoiliac aneurysms treated with iliac branch devices (IBDs). METHODS Patients with pre-IBD and post-IBD computed tomography imaging were included. We measured arterial diameters, stenosis, calcification, bifurcation angles, and tortuosity indices using a standardized, validated protocol. A composite of ipsilateral AIE was defined, a priori, as occlusion, type I or III endoleak, device constriction, or clinical event requiring reintervention. Paired t-test compared tortuosity indices and splay angles pretreatment and post-treatment for all IBDs and by device material (stainless steel and nitinol). Two-sample t-test compared anatomical changes from pretreatment to post-treatment by device material. Logistic regression assessed associations between AIE and anatomic measurements. Analysis was performed by IBD. RESULTS We analyzed 297 patients (286 males, 11 females) with 331 IBDs (227 stainless steel, 104 nitinol). Median clinical follow-up was 3.8 years. Iliac anatomy was significantly straightened with all IBD treatment, though stainless steel IBDs had a greater reduction in total iliac artery tortuosity index and aortic splay angle compared to nitinol IBDs (absolute reduction -0.20 [-0.22 to -0.18] vs. -0.09 [-0.12 to -0.06], P < 0.0001 and -19.6° [-22.4° to -16.9°] vs. -11.2° [-15.3° to -7.0°], P = 0.001, respectively). There were 54 AIEs in 44 IBDs in 42 patients (AIE in 13.3% of IBD systems), requiring 35 reinterventions (median time to event 41 days; median time to reintervention 153 days). There were 18 endoleaks, 29 occlusions, and 5 device constrictions. There were no strong associations between anatomic measurements and AIE overall, though internal iliac diameter was inversely associated with AIE in nitinol devices (nAIE, nitinol = 8). CONCLUSIONS Purpose-built IBDs effectively treat aortoiliac disease, including that with tortuous anatomy, with a high patency rate (91.5%) and low reintervention rate (9.1%) at 4 years. Anatomic predictors of AIE are limited.

Abstract
OBJECTIVE This study used unsupervised machine learning (UML) cluster analysis to explore clinical phenotypes of endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) patients based on radiomics. METHOD We retrospectively reviewed 1785 patients with infra-renal AAA who underwent elective EVAR procedures between January 2010 and December 2020. Pyradiomics was used to extract the radiomics features. Statistical analysis was applied to determine the radiomics features that related to severe adverse events (SAEs) after EVAR. The selected features were used for UML cluster analysis in training set and validation in test set. Comparison of basic characteristics and radiomics features of different clusters. The Kaplan-Meier analysis was conducted to generate the cumulative incidence of freedom from SAEs rate. RESULT A total of 1180 patients were enrolled. During the follow-up, 353 patients experienced EVAR-related SAEs. In total, 1223 radiomics features were extracted from each patient, of which 23 radiomics features were finally preserved to identify different clinical phenotypes. 944 patients were allocated to the training set. Three clusters were identified in training set, in which patients had identical clinical characteristics and morphological features, while varied considerably of selected radiomics features. This encouraging performance was further approved in the test set. In addition, each cluster was well differentiated from other clusters and Kaplan-Meier analysis showed significant differences of freedom from SAEs rate between different clusters both in the training (p = .0216) and test sets (p = .0253). CONCLUSION Based on radiomics, UML cluster analysis can identify clinical phenotypes in EVAR patients with distinct long-term outcomes.

Abstract
OBJECTIVE There are a variety of methods used today to treat common iliac aneurysms with endovascular techniques. Of these approaches, little is known about whether a particular limb strategy influences endoleak, reintervention, or aneurysm regression rates. We present 5-year data comparing endoleak, stent graft migration, fracture, aneurysm sac dynamics, and aortic rupture rates among patients treated with bell bottom limbs (BB), iliac branch endoprosthesis (IBE), and coil and cover (CC) approaches from the Global Registry for Endovascular Aortic Treatment registry. Secondary end points were all-cause mortality, stroke, reintervention, and paraplegia. METHODS Subjects from the GORE Global Registry for Endovascular Aortic Treatment were enrolled over a 5-year period from October 2017 to August 2022. We included 924 subjects in this study. Statistical data was generated on R software and limb groups were compared using the Pearson's χ2 test and the Kruskal-Wallis rank-sum test. RESULTS We found no statistical difference in endoleak rates, stent graft migration, fracture, or aortic rupture when stratified by limb strategy. There was no difference between limb approaches with regard to aneurysm sac dynamics among those with abdominal aortic aneurysms and common iliac aneurysms. Similarly, no statistical difference between limb strategies was found in all-cause mortality, stroke, paraplegia, or reintervention rates. Among patients that required an additional graft during reintervention, the highest rates were found within the IBE group 8.6%, compared with BB group 2.2% and CC group 1.3% (P = .006). CONCLUSIONS Overall, there was no difference among limb strategies in endoleak rates, stent graft migration, aneurysm sac dynamics, aortic rupture rates, or our secondary end points. Increased rates of reintervention requiring an additional graft within the IBE group is noteworthy and must be weighed against the adverse effects of hypogastric sacrifice with the CC approach or potentially less advantageous seal zones in the BB approach. This finding suggests that all limb approaches have equivalent effectiveness in managing the aneurysmal common iliac artery; thus, the choice of limb strategy should be individualized and remain at physician discretion. Future research should include a more robust sample size to reproduce these findings.

Abstract
Hypogastric artery embolization is performed during endovascular aneurysm repair (EVAR) involving the common iliac artery. Within this case series, we have observed elevated rates of sac expansion subsequent to this intervention. April 2009 to March 2021, 22 patients underwent EVAR with hypogastric artery embolization. We evaluated the mid-term outcomes for these patients. The mean follow-up period was 57 months. We achieved a 100% technical success rate without open conversion and no hospital deaths. The rates of freedom from aneurysm expansion at 1, 3, and 5 years were 90.5%, 59.1%, and 37.5%, respectively. The percentage of sac expansion exceeding 5 mm was 54.5% (12/22). Combined endovascular aortic aneurysm repair and embolization of the hypogastric artery might be associated with a high rate of remote sac expansion. Larger trials are needed to verify risks and benefits.

Abstract
Revascularization of complex pelvic vascular anatomy presents an ongoing clinical challenge when treating aortoiliac disease. As vascular surgeons continue to intervene upon increasingly complex aortoiliac pathology, the role of pelvic revascularization is important for the preservation of pelvic organ function and prevention of devastating spinal cord ischemia. In this study we describe the indications, techniques, and clinical outcomes of a novel hybrid pelvic revascularization repair that focuses on optimizing revascularization while limiting pelvic surgical dissection during the management of complex aortic pathology in patients physiologically or anatomically unsuitable for traditional pelvic revascularization techniques.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) is one of the most common diseases in vascular surgery. Endovascular aneurysm repair (EVAR) can effectively treat AAA. It is essential to accurately classify patients with AAA who need EVAR. METHODS We enrolled 266 patients with AAA who underwent EVAR. Unsupervised machine learning algorithms (UMLAs) were used to cluster subjects according to similar clinical characteristics. To verify UMLA's accuracy, the operative and postoperative results of the 2 clusters were analyzed. Finally, a prediction model was developed using binary logistic regression analysis. RESULTS UMLAs could correctly classify patients based on their clinical characteristics. Patients in Cluster 1 were older, had a higher BMI, and were more likely than patients in Cluster 2 to develop pneumonia, chronic obstructive pulmonary disease, and cerebrovascular disease. The aneurysm diameter, neck angulation, diameter and angulation of bilateral common iliac arteries, and incidence of iliac artery aneurysm were significantly higher in cluster 1 patients than in cluster 2. Cluster 1 had a longer operative time, a longer length of stay in the intensive care unit and hospital, a higher medical expense, and a higher incidence of reintervention. A nomogram was established based on the BMI, neck angulation, left common iliac artery (LCIA) diameter and angulation, and right common iliac artery (RCIA) diameter and angulation. The nomogram was evaluated using receiver operating characteristic curve analysis, with an area under the curve of 0.933 (95% confidence interval, 0.902-0.963) and a C-index of 0.927. CONCLUSIONS Our findings demonstrate that UMLAs can be used to rationally classify a heterogeneous cohort of patients with AAA effectively, and the analysis of postoperative variables also verified the accuracy of UMLAs. We established a prediction model for new subtypes of AAA, which can improve the quality of management of patients with AAA.

Abstract
Purpose The aim of this study was to evaluate the effectiveness of the proposed method of preventive embolization of the internal iliac arteries using a liquid tantalum-containing ethylene vinyl alcohol copolymer. Methods In this nonrandomized clinical study with a retrospective control group, 55 patients with aneurysmal lesions of the infrarenal abdominal aorta participated. In the course of this study, we developed and implemented a method of preventive embolization of the ostia of the internal iliac artery using a liquid tantalum containing ethylene-vinyl alcohol copolymer having viscosity of 34 centipoise. The method was applied in 27 cases in patients with aneurysmal lesions of the infrarenal abdominal aorta with unilateral involvement of the common iliac artery. The maximum follow-up period at the stage of publication of the results was 24 months. Results The proposed method of embolization of the internal iliac artery is accompanied by an absolute risk of developing type II endoleak 0.393 (95% confidence interval: 0.2120-0.5738, p = 0.029); therefore, when using the new technique, there is a decrease in the absolute risk of developing type II endoleak by 39.3%. Conclusion The proposed method of preventive embolization allows to perform reliable occlusion of the internal iliac artery as proximally as possible, which makes it possible to maintain distal blood flow in the internal iliac artery and minimizes the risks of ischemic events.

Abstract
BACKGROUND Treating an abdominal aortoiliac aneurysm (AAIA) with endovascular methods can be challenging when the internal iliac artery (IIA) is involved. Embolizing the IIA and extending the limb to the external iliac artery (IIAE + EE) to prevent a type 2 endoleak may lead to pelvic ischemic complications. To avoid these complications, strategies that preserve the IIA, such as the bell-bottom technique (BBT) and the iliac branch device (IBD), have been proposed. This study aims to compare the outcomes of these three endovascular approaches for AAIA. METHODS Between January 2010 and December 2019, 174 patients with asymptomatic AAIA were enrolled in this retrospective analysis. They were divided into two groups: 81 patients underwent non-IIAE procedures, and 93 patients underwent IIAE procedures. The iliac limb study group consisted of 106 limbs treated with the BBT, 113 limbs treated with the IIAE + EE, and 32 limbs treated with the IBD. The primary outcomes included the 30-day mortality rate and intraoperative limb complications. The secondary outcomes included postoperative pelvic ischemia, freedom from reintervention, and the overall 10-year survival rate. RESULTS There was no significant difference in the perioperative mortality rate between the non-IIAE group (0%) and the IIAE group (2.1%), p = 0.500. The intraoperative limb complications did not differ significantly between the BBT limbs (7.5%), the IIAE + EE limbs (3.5%), and the IBD limbs (3.1%) groups, p = 0.349. The incidence of buttock claudication was significantly greater in the bilateral IIAE + EE group compared to the unilateral IIAE + EE and non-IIAE groups (25%, 11%, and 2.5%, p-value < 0.004), and was similar to the incidence of buttock rest pain with skin necrosis (15%, 0%, and 0%, p < 0.001). During the 10-year follow-up, the BBT limbs group had a significantly lower rate of iliac limb reintervention free time than the IIAE + EE limbs and the IBD limbs groups (88.7%, 98.2%, and 93.8%, p = 0.016). There was no significant difference in the overall 10-year survival rate between the non-IIAE and IIAE groups (51.4% vs. 55.9%, p = 0.703). CONCLUSIONS The early and late mortality rates were similar between the non-IIAE and IIAE groups. Preserving the IIA is recommended to avoid pelvic ischemic complications. Considering the higher rate of reintervention in the BBT group, the IBD strategy may be preferred for AAIA.

Abstract
OBJECTIVE The primary objectives of this scoping review were to assess the rate of and risk factors for type Ib endoleak and to evaluate the extent of the evidence base that links type Ib endoleak to short and long term outcomes in patients undergoing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA). METHODS Potentially eligible studies were searched in the Cochrane Central Register of Controlled Trials, MEDLINE, Web of Science Core Collection, SciELO Citation Index, Russian Science Citation Index, and KCI-Korean Journal Database. A scoping review was performed according to PRISMA extension for Scoping Reviews. RESULTS A total of 27 articles (four prospective registries and 23 retrospective cohort studies) dealing with type Ib endoleak were included in the final analysis. The number of patients reported on was 7 197, with follow up ranging between 12 months and 93 months. The reported frequency of type Ib endoleak in patients treated with EVAR ranged from 0% to 8%, Patient and or procedure related factors associated with risk of type Ib endoleak were (1) common iliac artery (CIA) diameter ˃ 18 mm requiring use of flared stent graft limbs (FLs) ˃ 20 mm, (2) length of CIA landing zone ˂ 20 mm, (3) marked iliac tortuosity, and (4) large initial AAA diameter. Depending on the study, 50 - 100% of type Ib endoleaks were corrected by endovascular means, with a reported immediate technical success of 100% in the studies providing this information. CONCLUSION Type Ib endoleak after EVAR has been reported to occur in 0 - 8% of cases. Several anatomical features, including CIA diameter ˃ 18 mm or requiring the use of FLs ˃ 20 mm, length of CIA landing zone ˂ 20 mm, marked iliac tortuosity, and large initial AAA diameter, could increase the risk of type Ib endoleak and may require alternative therapeutic options and or more stringent follow up. Therefore, this updated scoping review provides a comprehensive summary of the frequency, risk factors, prognosis, and treatment of type Ib endoleaks, and has identified knowledge gaps in the literature to guide further studies.

Abstract
INTRODUCTION Iliac aneurysms occur in 10% of patients with abdominal aortic aneurysms (AAA). There are three different endovascular approaches to their treatment in the context of infrarenal Endovascular Aortic Aneurysm Repair (EVAR): occlusion by coiling the internal iliac, incorporation using an iliac branch device, and delaying repair using a bell bottom limb. We sought to determine outcomes associated with these three strategies in our practice. METHODOLOGY The study was a combined prospective cohort study with a retrospective arm: prospective patient recruitment was done for 1 year from September 2019 and ended by September 2020, and retrospective data was collected from 2017 to 2019. Demographic, procedural, and imaging data was collected. SPSS was used to analyze data as patients were classified by limbs in four groups: iliac branched, bell bottom, coil and cover technique, and standard treated limbs. RESULTS There were 65 male and 4 female patients included in this study incorporating 137 limbs with a mean age of 78 years (SD ± 8 years). Two patients died after discharge (at 3 and 21 months postoperatively, without hospital admission) and five patients were lost to long-term follow-up. Three patients had operations that deviated from the plan: one was an IBD converted to bell bottom, one was an IBD that was converted to coil and cover, and one was a bell bottom that did not seal. Follow-up revealed late type IB endoleak in three bell bottom limbs and one limb treated with coil and cover. Common iliac occlusion occurred in one IBD, three bell bottom limbs, and two limbs treated with coil/cover technique. There were four additional ischemic events (buttock claudication in three and intestinal ischemia in one): all ischemic events occurred in the coil and cover group (p = .001). CONCLUSIONS Given the small population size examined in this study, there is no statistical difference between treatment groups; however, there was a trend toward bell bottom technique being associated with higher incidence of type IB endoleak. Coil and cover technique was associated with decreased IB endoleak; however, Buttock claudication and intestinal ischemia occurred more significantly in this group. Using IBD may be the best strategy to improve short- and long-term outcomes in patients with iliac aneurysms.

Abstract
<b><br>Aim:</b> The aim of our study was to assess the outcomes of stent-graft coverage of the hypogastric artery in the management of aortoiliac aneurysms with endovascular aneurysm repair (EVAR).</br> <b><br>Material and methods:</b> From January 2013 to March 2017, a total of 93 patients with aortoiliac aneurysms were treated with EVAR, which required occlusion of one or both of the hypogastric arteries. The patients of the Department of General, Vascular, Endocrine and Transplant Surgery were included in the study continuously and all procedures were elective.</br> <b><br>Results:</b> A total of 93 patients with aortoiliac aneurysms required a unilateral or bilateral procedure. Six patients were excluded from our study because they did not appear at their follow-up appointments. The study included 87 patients (80 men; mean age 71.9 (7.9) years, range 54-88), of which 30 had a unilateral procedure and 57 had a bilateral procedure. In 8 procedures (5.55%, n = 7) there was a type II endoleak that resolved during follow-up and required no surgical intervention. In 10 procedures (6.94%, n = 10) there was a type IB endoleak, with 8 procedures requiring surgical re-intervention in the form of an extension. In 12 procedures (8.33%, n = 9), the hypogastric artery thrombosed.</br> <b><br>Conclusion:</b> Coverage of the hypogastric artery by stent-graft has been proven to be a safe procedure, but there is still a risk of type II endoleak. Although 5.55% (n = 7) of the procedures in our study had a type II endoleak, none required surgical intervention.</br>.

Abstract
Considering the recent advancements in endovascular management of aortoiliac aneurysms, the use of an iliac branch device (IBD) to preserve pelvic blood flow and reduce complications caused by embolization of the internal iliac artery (IIA) is recommended by various guidelines. Although the outcomes reported following IBD placement are mainly positive and durable, IBD-specific complications such as a type Ic endoleak and associated reintervention may occur. Moreover, only one IBD device and one type of balloon-expandable bridging stent graft for IIA are currently available on the domestic market. Here we present two cases of type Ic endoleak following IBD placement. In both cases, IIA diameter was slightly larger than the basic instructions for use. Notably, the initial procedures were considered successful; however, type Ic endoleaks were detected on 1-month follow-up imaging. This finding emphasizes the need for a precise preoperative evaluation, intraoperative manipulation, and postoperative follow-up.

Abstract
OBJECTIVE Although female patients have a lower prevalence of abdominal aortic aneurysm (AAA), they seem to have a worse treatment outcome compared with male patients. Both maximum aneurysm diameter and aortic size index (ASI) are important indicators of the risk of AAA rupture, among which ASI has been shown capable of equalizing sex-related anatomical differences. Our study aimed to investigate whether sex is an independent risk factor for early postoperative mortality and how the diameter or ASI affects the association between sex and mortality. METHODS We performed a retrospective analysis of patients who enrolled in the AAA registry of the German Society of Vascular Surgery from 2013 to 2019. The patients were treated by either open surgical repair (OSR) or endovascular aneurysm repair (EVAR). The association between sex and 30-day mortality was investigated using logistic regression analysis. The interaction and mediating effects of maximum aneurysm diameter and ASI were investigated to verify their roles in the effect of sex on mortality. The relationships between the diameter (or ASI) and the risk of 30-day mortality in different sexes were demonstrated by the restricted cubic spline. RESULTS Overall, 23,275 cases were included in our analysis, with 20,130 male (86.5%) and 3139 female (13.5%) patients. Female patients had a smaller maximum aneurysm diameter (OSR, 55.23 ± 10.29 mm vs 58.05 ± 11.28 mm [P < .001]; EVAR, 54.06 ± 9.08 mm vs 56.11 ± 9.38 mm [P < .001]), but a higher ASI (OSR, 3.16 ± 0.71 vs 2.92 ± 0.69 [P < .001]; EVAR, 3.05 ± 0.66 vs 2.80 ± 0.59 [P < .001]) compared with male patients. The 30-day mortality rate was higher for female patients in both OSR (6.6% vs 4.2%; P = .002) and EVAR groups (1.8% vs 0.8%; P < .001). Logistic regression confirmed a significantly higher risk of 30-day mortality for female patients compared with male patients (odds ratio, 1.55; 95% confidence interval, 1.21-1.99; P = .001). No interaction was found between sex and diameter or ASI, but there were mediating effects for diameter and ASI in the effect of sex on 30-day mortality. For female patients, the risk of 30-day mortality linearly increased with the increase of diameter (PNonlinear = .089) or ASI (PNonlinear = .888), whereas the risk for male patients was U-shaped (for diameter, PNonlinear < .001; for ASI, PNonlinear = .020). CONCLUSIONS Sex is an independent risk factor for 30-day mortality after AAA repair. Both diameter and ASI are mediating factors for the effect of sex on 30-day mortality. The relationship between diameter or ASI and the risk of 30-day mortality is different for male and female patients.

Abstract
PURPOSE To evaluate the outcomes of preserving the internal iliac artery (IIA) with iliac branched devices (IBDs) during acute endovascular repair of ruptured aortoiliac aneurysms. MATERIAL AND METHODS This is a multicenter retrospective review of all consecutive patients undergoing acute endovascular repair of ruptured aortoiliac aneurysm with an IBD at 8 aortic centers between December 2012 and June 2020. A control group was used where the IIA was intentionally occluded from the same study period. The main outcome measures were 30-day mortality, major adverse events, technical success, and clinical success. Secondary outcomes were buttock claudication, primary patency, primary-assisted and secondary patency of the IBD, occurrence of endoleak types I/III, and reintervention. Values are presented as numbers and percentages or interquartile range in parenthesis. RESULTS Forty-eight patients were included in the study: 24 with IBD and 24 with IIA occlusion. There was no difference in demographics, cardiovascular risk factors, and aneurysm extent. Twenty (83%) of them were hemodynamically stable during the procedure as opposed to 14 (58%, p=.23) with the IIA occlusion. Technical success was achieved in all cases with a procedure time of 180 (133-254) minutes, 45 (23-65) of which were from IBD. There were 2 (8%) deaths during the first 30 days and 2 (8%) major complications unrelated to the IBD, whereas in the IIA occlusion, the figures were 10 (42%) and 7 (29%), respectively. No patient in the IBD group developed buttock claudication compared to 8 (57%, p<.0001) in the IIA occlusion group; 1 (4%) patient developed bowel ischemia on both groups, with 1 in the IIA occlusion group needing resection. The median follow-up duration was 17 months (interquartile range 2-39) for the IBD group, with a primary patency of 60±14% at 3 years that went up to 92±8% with reinterventions (8 reinterventions in 6 patients). When the first 90 days were disregarded, there were no differences in survival between the groups. CONCLUSION IBD is a valid alternative for maintaining the pelvic circulation for endovascular aortic aneurysm repair of ruptured aortoiliac aneurysms. The technical success and midterm outcomes are very satisfactory but require patient selection particularly regarding hemodynamic stability. The reintervention rate is considerable, mandating continuous follow-up. CLINICAL IMPACT This multicenter study demonstrates that ruptured aortoiliac aneurysms do not necessarily require mandatory occlusion of hypogastric arteries. Iliac branch devices are shown to be a valid alternative in highly selected cases, with good midterm results, even if reinterventions are required in a significant proportion of patients.

Abstract
We describe the case of a 78-year-old man presenting with multiple oedematous erythemas, fever, and arthralgia who subsequently developed neutrophil infiltration into the cartilage of the bilateral auricularis, consistent with relapsing polychondritis. A skin biopsy of the erythema on his right arm showed dense neutrophilic infiltration into the dermis, while a bone marrow aspirate revealed myelodysplastic syndromes with characteristic vacuoles in myeloid precursor cells. Although the patient achieved remission with high-dose oral prednisolone, the inflammatory symptoms relapsed, and he was resistant to colchicine and cyclosporine. The patient spontaneously developed left leg oedema and high-output cardiac failure caused by an arteriovenous fistula with a common iliac artery aneurysm. We successfully performed a two-stage surgery using internal iliac artery coil embolisation and endovascular aortic repair of the iliac aneurysm. We assumed the patient was suffering from large-vessel vasculitis such as giant cell arteritis or Takayasu's arteritis. We treated him with tocilizumab in addition to prednisolone, and the febrile events and elevated C-reactive protein levels improved. One year later, sequencing of ubiquitylation-initiating E1 enzyme using peripheral blood leucocytes revealed somatic variants (c.121A>C p.Met41Leu), confirming the diagnosis of vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome. This case suggests that arteriovenous fistula could be a complication of VEXAS syndrome with large-vessel vasculitis, and adequate surgical intervention and prompt diagnosis are essential for rescue. Although arteriovenous fistula is a rare complication of VEXAS syndrome, physicians should be aware of this complication to ensure prompt diagnosis and timely surgical intervention.

Abstract
OBJECTIVE Our aim was to describe the racial and ethnic differences in presentation, baseline and operative characteristics, and outcomes after aortoiliac aneurysm repair. SUMMARY OF BACKGROUND DATA Previous studies have demonstrated racial and ethnic differences in prevalence of abdominal aortic aneurysms and showed more complex iliac anatomy in Asian patients. METHODS We identified all White, Black, Asian, and Hispanic patients undergoing aortoiliac aneurysm repair in the VQI from 2003 to 2019. We compared baseline comorbidities, operative characteristics, and perioperative outcomes by race and ethnicity. RESULTS In our 60,435 patient cohort, Black patients, followed by Asian patients, were most likely to undergo repair for aortoiliac (W:23%, B:38%, A:31%, H:22%, P < 0.001) and isolated iliac aneurysms (W:1.0%, B:3.1%, A:1.5%, H:1.6%, P < 0.001), and White and Hispanic patients were most likely to undergo isolated aortic aneurysm repair (W:76%, B:59%, A:68%, H:76%, P < 0.001). Black patients were more likely to undergo symptomatic repair and underwent rupture repair at a smaller aortic diameter. The iliac aneurysm diameter was largest in Black and Asian patients. Asian patients were most likely to have aortic neck angulation above 60 degree, graft oversizing above 20%, and completion endoleaks. Also, Asian patients were more likely to have a hypogastric artery aneurysm and to undergo hypogastric coiling. CONCLUSION Asian and Black patients were more likely to undergo repair for aortoiliac and isolated iliac aneurysms compared to White and Hispanic patients who were more likely to undergo repair for isolated aortic aneurysms. Moreover, there were significant racial differences in the demographics and anatomic characteristics that could be used to inform operative approach and device development.

Abstract
In the past two decades, endovascular aortic repair (EVAR) of abdominal aortic aneurysm (AAA) has become the first line treatment for infrarenal AAA repair in many countries. While short-term results are good, concerns have been raised about long-term durability. Changes in aortoiliac anatomy, especially at the landing zones, could play a role in EVAR failure over time. The current study aimed to determine certain morphological changes in the distal iliac landing zone after EVAR implantation, as well aspossible risk factors associated with iliac sealing failure. In a retrospective analysis of a tertiary single-centre registry, including patients treated with EVAR between January 2008 and July 2018, clinical follow-up data were assessed, and computer tomography (CT) imaging was evaluated regarding morphological changes in the iliac anatomy during follow-up. For clinical analysis all patients with a minimum follow-up of one year were included; for morphological analysis of iliac anatomy all patients with available CT follow-up of a minimum of one year and a minimum of two CT scans were included. Overall, 127 out of 241 treated patients (92.1% male) were included in the clinical follow-up. Complete CT imaging of 99 iliac arteries in 55 patients was available for morphological analysis. Median postoperative follow-up (FU) for these patients was 33 months (IQR 31; min−max: 12−124). Incidence of type 1b endoleak was 3% but iliac limb detachment from the vessel wall was seen in 18.2% of the target vessels. There was a significant difference in oversizing in iliac limbs with detachment (median 13.9%, IQR 23.1) vs. without detachment (median 23.1%, IQR 19.1) (p = 0.034). Iliac arteries at the landing zone showed a significant diameter increase independent of an endoleak presence (overall cohort median diameter increase at one year 23.1 mm; at two years 0 mm; at three years 4.9 mm). Iliac arteries with detachment (median 14.4%; IQR 23.9) showed a significantly higher diameter increase at the landing zone after four years compared to arteries without detachment (median 5.3%; IQR 9) (p = 0.042). Oversizing correlated positively with an iliac diameter increase at the landing zone over time (3 m: p= 0.001; one year: p < 0.001; two years: p < 0.001; three years: p = 0.006). Older patients showed a significantly lower diameter increase at the distal landing zone over time than younger patients in the first two years after EVAR (p < 0.001/r = −0.606 after two years). In the current study, iliac limb oversizing was associated with increased dilatation of the distal landing zone during a three-year follow-up, while iliac limb detachment was observed less often. An older age was inversely associated to the iliac diameter increase. Future studies should clarify the association between stent graft oversizing, age, and changes in the iliac anatomy in order to identify parameters that affect EVAR durability.

External iliac artery extension causes greater aneurysm sac regression than the bell-bottom technique or iliac branch endoprosthesis for repair of concomitant infrarenal aortic and iliac artery aneurysm. J Vasc Surg 2022; 76:132-140. [PMID: 34998943 DOI: 10.1016/j.jvs.2021.12.062] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Accepted: 12/13/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVE Aneurysmal extension of abdominal aortic aneurysms (AAAs) to the common iliac artery (CIA) presents a technical challenge to successful endovascular abdominal aortic aneurysm repair (EVAR). In the present study, we compared sac shrinkage and perioperative outcomes after the bell-bottom technique (BBT), internal iliac artery embolization and external iliac artery extension (EIE), and iliac branch endoprosthesis (IBE). METHODS Using the Vascular Quality Initiative database, a retrospective analysis was conducted for patients who had undergone EVAR from 2013 to 2019. The demographic, anatomic, and perioperative data were analyzed. All patients with a proximal aortic neck length <10 mm and aortic graft diameter >32 mm were excluded from the analysis. The patients were subdivided into four groups according to the distal limb strategy: group 1, control group with a bilateral common iliac artery limb <20 mm; group 2, BBT with either a unilateral or bilateral limb >20 mm; group 3, EIE technique; and group 4, IBE. The primary endpoint was the maximal change in the aortic diameter during follow-up. The secondary endpoints included postoperative complications and the rate of endoleak. RESULTS The records for 14,455 patients who had undergone EVAR were queried and 5788 met the anatomic criteria. The average age was 73 years, and 86.3% were men. The maximal change in the aortic diameter in the control, BBT, IBE, and EIE groups was -7.2 mm, -6.1 mm, -4.6 mm, and -6.8 mm, respectively (P = .06). The differences were not statistically significant on univariate analysis at an average follow-up of 405 days. However, on multivariable analysis (P = .01), compared with the control group, the BBT and IBE groups were 18.4% (odds ratio [OR], 0.816; 95% confidence interval [CI], 0.68-0.98) and 48.0% (OR, 0.52; 95% CI, 0.33-0.82) less likely to experience aneurysmal shrinkage, respectively. In contrast, the EIE group showed no significant difference in shrinkage compared with that in the control group. Multivariable analysis of the groups also revealed that compared directly with the BBT group, the EIE group was 69.5% more likely to have experienced shrinkage in the aortic aneurysmal diameter (OR, 1.70; 95% CI, 1.05-2.75). The BBT and IBE groups had a significantly higher rate of type II endoleaks (17.63% and 16.95%, respectively; P = .03). The EIE group had a higher rate of type Ib endoleaks (1.9%) compared with the BBT (1.1%), IBE (1.7%), and control (0.3%) groups (P = .01). No differences were found between the groups in terms of postoperative myocardial infarction (P = .47) or respiratory (P = .61) or intestinal (P = .71) complications. However, the rates of limb complications and reoperation were higher in the EIE group. CONCLUSIONS The present study revealed that the EIE technique was more likely to demonstrate shrinkage in the aortic aneurysmal diameter than were the BBT and IBE groups compared with the control group on multivariable analysis. The EIE technique was also more likely to result in aneurysmal sac shrinkage than was the BBT group, albeit with greater rates of limb-related complications.

Successful endovascular repair of iliac artery aneurysms with unsuitable anatomy by combining unibody bifurcated endograft and iliac branch systems to preserve hypogastric artery blood flow: a report of two cases. J Cardiothorac Surg 2022; 17:93. [PMID: 35505409 PMCID: PMC9066821 DOI: 10.1186/s13019-022-01855-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Accepted: 04/21/2022] [Indexed: 11/16/2022] Open
Abstract
Background To overcome the anatomical limitation of a narrow aorta and short length from the renal artery to the terminal aorta, unibody endograft AFX2 and iliac branch endoprosthesis (IBE) can be combined. Case presentation Case 1: The first patient was an 89-year-old woman who had a right saccular common iliac artery (CIA) aneurysm (38 mm); the abdominal aorta was not aneurysmal (diameter, 19 mm). The right CIA’s origin was 10 mm in diameter. A bifurcated AFX2 was placed in an ordinary manner. Then, IBE was inserted in the right leg of the AFX2. Case 2: The second patient was an 87-year-old man diagnosed with an abdominal aortic aneurysm (55 mm), right dissecting CIA aneurysm (20 mm), and right hypogastric artery aneurysm (22 mm) extending to the bifurcation of the superior and inferior gluteal arteries. The length between the renal artery and terminal aorta was 107 mm. The beginning of the right CIA was segmentally stenotic (13 mm). A bifurcated AFX2 was placed in the infrarenal aorta; IBE was advanced to the origin of the right limb of the AFX2. To control the type 1b endoleak, the right superior gluteal artery was embolized with coils and internal iliac components were deployed toward the inferior gluteal artery. Satisfactory results were obtained in both cases. Conclusion The AFX2 main body and IBE could be combined to preserve hypogastric blood flow and overcome anatomical limitations.

Abstract
Background Iliac branch devices (IBDs) are valid tools for internal iliac artery preservation during endovascular abdominal aortic aneurysm and iliac aneurysm repair. The purpose of this study was to evaluate the effectiveness of a novel IBD with an embedded branch configuration. Method A typical iliac artery model was reconstructed, and two models were manufactured using three-dimensional printing technology. The novel IBD was deployed into one iliac artery model by an experienced vascular surgeon. A mock circulation loop (MCL) and a computational fluid dynamics (CFD) simulation were used to investigate the haemodynamic parameters of the iliac models without (Model A) and with (Model B) the IBD. A morphological analysis was conducted using computed tomography angiography and medical endoscopy. The flow distribution rate (FDR) and energy loss (EL) were used to quantify IBD performance. Results The FDR of the right internal iliac artery in the MCL of Model A and Model B was 18.88 ± 0.12% and 16.26 ± 0.09%, respectively (P = 0.0013). The FDR of the right internal iliac artery in the CFD simulation of Model A and Model B was 17.52 and 14.49%, respectively. The EL of Model A was greater than Model B in both the MCL and the CFD simulation. Compared with Model A, Model B had a larger region (8.46 vs. 3.64%) with a relative residence time of >20 Pa−1 at peak systole. Meanwhile, the area where the oscillatory flow index was >0.4 was significantly smaller in Model B than in Model A (0.46 vs. 0.043%). The region with an average wall shear stress of >4 Pa was greater in Model B than in Model A (0 vs. 0.22%). Conclusion The MCL and CFD simulation showed that the novel IBD had little impact on the FDR and EL of the iliac artery models. However, the IBD might be an effective tool for the treatment of abdominal aortic/iliac aneurysms that extend into branches. Further investigations are warranted to confirm whether this IBD could be useful in the clinic.

A systematic review and meta-analysis of the clinical effectiveness and safety of unilateral versus bilateral iliac branch devices for aortoiliac and iliac artery aneurysms. J Vasc Surg 2022; 76:1089-1098.e8. [PMID: 35314303 DOI: 10.1016/j.jvs.2022.03.005] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 03/04/2022] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Iliac branch devices (IBDs) have been utilized in the treatment of aortoiliac and isolated iliac artery aneurysms. The aims of this systematic review and meta-analysis were to investigate the clinical effectiveness and safety of IBDs. METHODS A systematic review of the literature was conducted by identifying studies in the Medline, EMBASE, and Cochrane databases regarding the outcomes of IBDs in aortoiliac or isolated iliac artery aneurysms between May 2006 and December 2020. Individual studies were evaluated for the following major outcomes: technical success, 30-day mortality, primary patency, endoleak, reintervention, and rates of pelvic ischemia. Furthermore, sub-group meta-analyses were performed to compare the pelvic ischemic events in patients with bilateral IBDs, unilateral IBDs and bilateral internal iliac artery (IIA) embolization/coverage. RESULTS 45 studies with a total of 2736 patients undergoing unilateral or bilateral IBDs met inclusion criteria and were included in the analysis. The pooled technical success rate of IBD was 98.0% (CI: 97.3-98.7%). Following IBD treatment, the 30-day mortality rate was 0.4% (CI: 0.07-0.70%); 30-day patency was 98.4% (CI: 97.7-99.0%); buttock claudication developed in 1.84% (CI: 1.26-2.41%); endoleak occurred in 11.9% (CI: 9.2-14.7%) and re-intervention in 7.6% (CI: 5.65-9.58%). Furthermore, in the patients with bilateral iliac artery involvement the pooled estimate rates of buttock claudication were 0.7% in bilateral IBD group, 7.9% in unilateral IBD with contralateral IIA embolization patients and 33.8% in bilateral IIA embolization/coverage patients, which were statistically significant among the three groups. Sexual dysfunction was 5.0% in bilateral IIA occlusion group, which was significantly higher than that in IBD groups. CONCLUSIONS The utilization of IBDs in treatment of aortoiliac or isolated iliac artery aneurysms is associated with high technical success rates as well as low incidences of pelvic ischemia. The risk of postoperative buttock claudication can be further decreased with both IIA preservation if patients are anatomically suitable for bilateral IBDs.

Application of a Novel Common-Iliac-Artery Skirt Technology (CST) in Treating Challenge Aorto-Iliac or Isolated Iliac Artery Aneurysms. Front Cardiovasc Med 2021; 8:745250. [PMID: 34733894 PMCID: PMC8558348 DOI: 10.3389/fcvm.2021.745250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 09/06/2021] [Indexed: 11/13/2022] Open
Abstract
Purpose: To report a novel common-iliac-artery skirt technology (CST) in treating challenge iliac artery aneurysms. Methods: When required healthy landing zone of common iliac artery (CIA) is not available, CST is a strategy to exclude the internal iliac artery (IIA) and prevent IIA reflux without need of embolization. Patients who received endovascular aneurysm repair (EVAR) in our center from 2014 to 2020 were retrospectively screened, and patients treated with CST or with IIA embolization (IIAE) were enrolled. Results: After retrospective screen of 524 EVAR patients, 39 CST patients, 26 IIAE patients, and 7 CST + IIAE patients were enrolled in this study. CST group suggested to have more aged, hyperlipemia, and smoking patients than IIAE group. Two groups had comparable maximal diameter of abdominal aorta (AA), CIA, EIA, but larger diameter of IIA (CST 19.82 ± 2.281 vs. IIAE 27.82 ± 3.401, p = 0.048), and CIA bifurcation (CST 25.01 ± 1.316 vs. IIAE 29.76 ± 2.775, p = 0.087) was found in IIAE group. Anatomy of 79.5% of CST patients and 92.3% of IIAE patients (p = 0.293) was not suitable for potential use of iliac branch device. CST group had significant shorter surgery time (CST 97.42 ± 3.891 vs. IIAE 141.0 ± 8.010, p < 0.001), shorter hospital stay (CST 15.35 ± 0.873 vs. IIAE 19.32 ± 1.067, p = 0.009), lower in-hospital [CST 0% (0/39) vs. IIAE 11.5% (3/26), p = 0.059] and 1-year follow-up stent related MAEs [CST 6.7% (2/30) vs. IIAE 28.6% (6/21), p = 0.052], but comparable mortality and stent related MAEs for all-cohort follow-up analysis comparing to IIAE group. In our study, a lower in-hospital buttock claudication (BC) rate for CST (CST 20.5% vs. IIAE 46.2%, p = 0.053) and a comparable erectile dysfunction (ED) rate (CST 10.3% vs. IIAE 23.1%, p = 0.352) were found between CST and IIAE groups. After 1 year, both groups had about one third relief of BC symptoms [CST 33.3% (4/12) vs. IIAE 30.7% (4/13), p = 1.000]. Subgroup analysis of 14 patents concomitant with IIA aneurysm in CST group and the 7 CST + IIAE patients were carried out, and no difference was found in mortality, stent MAEs, sac dilation, or reintervention rate. Last, illustration of seven typical CST cases was presented. Conclusion: In selected cases, the CST is a safe, feasible-and-effective choose in treating challenge iliac artery aneurysms and preventing IIA endoleak.

Abstract
OBJECTIVE The Gore Excluder Iliac Branch Endoprosthesis (IBE) was developed to preserve perfusion in the hypogastric artery after endovascular repair of aorto-iliac aneurysms. This study reports the 12 month technical and clinical outcomes of treatment with this device. METHODS This study was a physician initiated international multicentre, prospective cohort study. The primary endpoint was primary patency of the hypogastric branch at 12 months. Secondary endpoints included technical and clinical outcomes. Patients with an indication for elective treatment with the Gore Excluder IBE were enrolled between March 2015 and August 2018. Baseline and procedural characteristics, imaging data, physical examinations and questionnaire data (Walking Impairment Questionnaire [WIQ], EuroQol-5-Dimensions [EQ5D], International Index of Erectile Function 5 [IIEF-5]) were collected through 12 month follow up. RESULTS One hundred patients were enrolled of which 97% were male, with a median age of 70.0 years (interquartile range [IQR] 64.5 - 75.5 years). An abdominal aortic aneurysm (AAA) above threshold for treatment was found in 42.7% and in the remaining patients the iliac artery diameter was the indication for treatment. The maximum common iliac artery (CIA) diameter on the Gore Excluder IBE treated side was 35.5 mm (IQR 30.8 - 42.0) mm. Twenty-two patients received a bilateral and seven patients had an isolated IBE. Median procedural time was 151 minutes (IQR 117 - 193 minutes) with a median hospital stay of four days (IQR 3 - 5 days). Primary patency of the IBE at 12 month follow up was 91.3%. Primary patency for patients treated inside and outside the instructions for use were 91.8% and 85.7%, respectively (p = .059). Freedom from secondary interventions was 98% and 97% at 30 days and 12 months, respectively. CIA and AAA diameters decreased significantly through 12 months. IIEF-5 and EQ5D scores remained stable through follow up. Patency of the contralateral internal iliac artery led to better IIEF-5 outcomes. WIQ scores decreased at 30 days and returned to baseline values through 12 months. CONCLUSION Use of the Gore Excluder IBE for the treatment of aorto-iliac aneurysms shows a satisfactory primary patency through 12 months, with significant decrease of diameters, a low re-intervention rate, and favourable clinical outcomes.

Abstract
OBJECTIVE The objective of this study is to report the medium-term results of GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE, W. L. Gore & Associates, Flagstaff, Ariz) for the treatment of aortoiliac aneurysms by using the GALIBER registry. METHODS Patients with aortoiliac or isolated common iliac/hypogastric aneurysms treated with Iliac Branch Endoprosthesis device between January 2014 and May 2019 were prospectively collected from 5 centers. Demographic, clinical, and radiologic data were extracted from electronic databases. Technical success was defined as successful implantation of the Iliac Branch Endoprosthesis device with exclusion of aortoiliac aneurysm, as well as patency of Iliac Branch Endoprosthesis in the follow-up. Iliac Branch Endoprosthesis patency was evaluated by Doppler ultrasound and/or computed tomography based on the protocol of each participant center. Follow-up was 731 days +/- 499. RESULTS Between January 2014 and May 2019, 105 iliac arteries were treated with GORE® IBE device, in 81 patients (79 men, two women; mean age 71, range 52-91). Only seven patients (8.6%) were symptomatic. 60 patients (74%) had aortic and iliac enlargement. Thirty-three patients presented bilateral iliac aneurysms (40.7%): In twenty-four (29.6%) patients, an Iliac Branch Endoprosthesis device was implanted in both sides, and in nine patients (11.1%), one Iliac Branch Endoprosthesis was used with the embolization of the contralateral hypogastric artery. Technical success was achieved in the 99% (104/105 iliac branch device implanted). There were no procedural deaths or type I or III intraoperative endoleaks observed. During the follow-up (range 55-1789 days), 28 (34.5%) type II endoleaks were observed and one (1.2%) type Ia was observed. The patency of the hypogastric arteries treated with the iliac branch device was 98.1% during the follow-up (range 55-1789 days). In 30% of the patients with contralateral hypogastric embolization, some kind of complications was observed in the embolizated side: one developed ischemic colitis and two buttock claudication. CONCLUSIONS Preservation of internal iliac artery with the Iliac Branch Endoprosthesis device can be performed safely with excellent technical success and good medium-term patency rates. These results support hypogastric preservation whenever possible to prevent ischemic complications.

Abstract
OBJECTIVES Iliac branch devices (IBDs) are modular, bifurcated endografts designed to preserve hypogastric flow during endovascular aortoiliac aneurysm repair. We report our single center outcomes, and describe the unique complications of these devices: inability to cannulate the hypogastric artery (technical failure), occlusion of the internal branch, and type III endoleak from separation of components between the main body and IBD. METHODS A prospectively maintained institutional database of patients undergoing IBD implantation between 2014 and 2019 was reviewed. Technical and clinical outcomes were evaluated. We then identified patients having one of the IBD-specific complications and patient, anatomic, and procedural data were analyzed to identify factors associated with these failures. RESULTS Sixty-four IBDs were placed in 59 patients during the study period. Mean age was 71.2 ± 8.6, and 92% were male. A 74.6% of patients had a current or prior abdominal aortic aneurysm, and 9.4% had a hypogastric aneurysm. Technical success was achieved in 60/64 cases (93.8%); prior endovascular aortic repair was associated with technical failure (P = 0.04). There were 5 instances of component separation between the main body and the IBD: 3 occurred intraoperatively and were repaired with additional bridging components, and 2 occurred on late follow-up and required reintervention. Increased tortuosity index of both aortoiliac (1.7 ± 0.4 vs. 1.3 ± 02, P = 0.04) and iliac-specific (3.9 ± 2.4 vs. 1.9 ± 0.9, P = 0.03) segments were significantly associated with component separation, as was the use of larger internal iliac components (13.9 ± 2.4 vs. 11.1 ± 2.3 mm, P = 0.04). Internal branch occlusions occurred in 4 patients (6.7%). Two were successfully reopened with endovascular procedures, with two being asymptomatic. No specific factors were found to be predictive of branch occlusion. CONCLUSIONS IBD-specific complications occur rarely. History of prior endovascular aortic repair is associated with technical failure, while increased aortic and iliac tortuosity are predictive of component separation and type III endoleak. Severe tortuosity should be carefully considered when planning for IBD.

Morphological applicability of currently available stent grafts in the endovascular repair of asymptomatic abdominal aortic aneurysm in East-Central European patients. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2021; 17:93-100.

Abstract
Introduction Currently, there is a wide range of commercially available devices for endovascular aneurysm repair (EVAR) that differ in terms of both anatomical requirements and the technology and technique of deployment. Aim To assess the applicability of currently commercially available devices for EVAR in the treatment of an asymptomatic abdominal aneurysm (AAA). Material and methods The study group included 100 patients with infrarenal AAA with a maximum diameter ≥ 50 mm, qualified for invasive treatment at the University Hospital in 2013–2014. The aortoiliac morphological characteristics of the AAA were evaluated on preoperative computed tomography angiograms using the OsiriX DICOM viewer in the 3D-MPR mode. The morphological applicability of 14 types of CE-marked and FDA-approved stent grafts was determined based on their instructions for use (IFU). Results EVAR was feasible with at least one of the analysed devices in 68% of patients. The morphological applicability was as follows: Excluder Conformable (65%), Ovation iX (51%), Endurant II (47%), Treo (45%), Excluder C3 (45%), AFX 2 (45%), Incraft (44%), E-tegra (44%), Zenith Alfa (41%), Zenith Flex (40%), Anaconda (39%) Aorfix (37%), Altura (34%), and E-vita (20%). The differences in the stent graft applicability were statistically significant (p < 0.001). A wide diameter of the common iliac artery, angulated proximal neck, and diameter of proximal neck out of range constituted the most frequent causes of EVAR inapplicability. Conclusions The IFU-based applicability of currently available AAA stent graft systems differs significantly. Despite the constant evolution of EVAR technology, at least 32% of AAA will require a different therapeutic approach.

Abstract
Giant aortoiliac aneurysm is a rare nosological entity. Owing to the increased diameter, the risk of rupture is extremely high and, similarly, the repair is extremely challenging. In this article, open surgical repair of a ruptured giant aortoiliac aneurysm in a 72-year-old male is described. A bifurcated Dacron graft was used with left internal iliac artery revascularization, while the contralateral internal iliac artery was ligated. The patient had an uneventful recovery.

Abstract
OBJECTIVE The devastating event of a ruptured abdominal aortic aneurysm (rAAA) in patients who have survived a previous AAA repair, either elective or urgent, is a feared and quite uncommon event. It has been suggested to partly explain the loss of the early survival benefit for endovascular aortic repair (EVAR) vs open surgical repair (OSR). The main objective of this study was to report the national incidence rate, risk factors and outcome of post-EVAR ruptures. Secondarily, the national incidence rate of ruptures after OSR (post-OSR ruptures) was investigated. METHODS We conducted a nationwide, population-based, retrospective cohort study using the inpatient and outpatient entries for all patients >40 years of age, receiving their first (index) surgical procedure for AAA, from 2001 to 2015. Only patients surviving their index procedure were included. The primary outcome was rAAA, registered after discharge from the index procedure (EVAR or OSR), identified in the Swedish National Patient Registry and the Cause of Death Registry. RESULTS In total, 14,859 patients survived their primary (index) AAA procedure. There were 6470 EVAR procedures, 5893 for intact AAA (iAAA) and 577 for rAAA. Of the 6470 EVAR patients, 86 cases of post-EVAR rupture were identified, corresponding with a cumulative incidence of 1.3% over a mean follow-up time of 3.9 years. The incidence rate was 3.4 (95% confidence interval [CI], 2.7-4.2)/1000 person-years. The independent risk factors identified for post-EVAR rupture were rAAA at index surgery HR 2.4 (95% CI, 1.4-4.1, p 0.002) and age (hazard ratio, 1.1; 95% CI, 1.0-1.1; P < .001). Freedom from post-EVAR rupture was 99%, 98%, and 96% at 3, 5, and 10 years, respectively. Total and postoperative mortality after post-EVAR rupture were 42% and 17% (30 days), 45% and 22% (90 days), and 53% and 33% (1 year). The incidence rate of post-OSR rupture was 0.9/1000 person-years (95% CI, 0.7-1.2). CONCLUSIONS Post-EVAR rupture is a rare complication that can occur at any time after the index EVAR procedure. This finding may have implications for the discussion of limited follow-up programs and for the choice of procedure in patients with an AAA with a long life expectancy. An rAAA as the indication for the index surgery and age were identified as risk factors for post-EVAR rupture. The mortality associated with post-EVAR rupture is high, but lower than that of primary rAAA. The much lower risk of post-OSR rupture was confirmed, but must not be neglected as a possible late complication.

Abstract
AIM The study was aimed at assessing efficacy and safety of endovascular treatment of abdominal aortic aneurysms based on 11-year experience with implantation of stent grafts. PATIENTS AND METHODS We retrospectively analysed outcomes of treatment of 242 patients with abdominal aortic aneurysm during the period from 2008 to 2019. Of these, 210 (86.78%) were males, mean age 69.32±7.36 years. Diagnosis was made using colour duplex scanning and contrast-enhanced multislice spiral computed tomography, with implanting the following stent grafts: Ella - 44, Ovation Prime - 33, Anaconda - 13, Endurand - 77, Aortix - 2, Zenith - 33, Seal - 39, with one endoprosthesis placement failed. Assessing safety of the operation, we took into consideration lethality due to aortic rupture/thrombosis. Efficacy was taken to mean technical success of the operation (implantation of all components of the endograft without switch to open surgery), the number of reoperations. RESULTS Technical success of the operation was achieved in 98.35% of cases. In 1 case due to pronounced arterial calcification for technical reasons we failed to position the stent graft and in another case - the contralateral leg of the Ella prosthesis. The early postoperative period revealed: type A1 endoleak - 3.7%, type IB - 4.13%, type IIA - 6.6%, type IIB - 4.54%, type III - 0.83%, type IV - 0.83%. Repeat operations were performed in 20 (8.2%) patients within 30 days after the intervention and in 32 (13.22%) in the remote period. In the early postoperative period two conversions were performed: 1) iliorenal bypass grafting for restoration of blood flow through the renal artery occluded by endoprosthesis wall; 2) evacuation of retroperitoneal haematoma due to rupture of the common femoral artery. Lethality during the whole period of follow up amounted to 32 (13.22%) cases. Of these, due to aortic complications 4.54% (n=11) and due to accompanying pathology 8.67% (n=21). A direct correlation was revealed between the aortic diameter and duration of the operation which in turn increases the risk of complications requiring re-operation or resulting in a lethal outcome (RR - 1; 95% CD 1- 1; p=0.026). CONCLUSION Our experience showed high safety and efficacy of stent graft implantation in treatment of patients with abdominal aortic aneurysms and high surgical risk.

Abstract
BACKGROUND To report a novel staged hybrid technique to treat complex juxtarenal abdominal aortic aneurysm (JAAA) associated with at least one iliac artery aneurysm (IA) with no adequate distal fixation zone. METHODS The novel technique herein described has two main "staged" steps. The first step consists in creating an adequate distal fixation zone by endovascular means; after hypogastric embolization an iliac stent-graft has placed from 5 mm above the aortic bifurcation to the external iliac artery. The second step is the surgical resection of the JAAA and graft placement sutured distally to the stent-graft which was always performed the day after. RESULTS The five cases included (mean age 74 years), were rejected for fenestrated or branched endovascular aortic repair or iliac branch devices. Four tube grafts and one aorto-bi-iliac graft were sutured to one stent-graft (N.=3), two stent-grafts in iliac kissing configuration (N.=1) and to a main body of a bifurcated stent-graft (N.=1). Mean follow-up duration was 14 (4-27) months with no mortality. Technical success was obtained in all cases (2 suprarenal clamping). Postoperative complications included two pleural effusions, two transient gluteal intermittent claudications, and one renal failure. CONCLUSIONS The technique herein described seems to be a feasible and cost-effective alternative treatment for selected concomitant complex JAAAs and IAs unsuitable for totally endovascular treatment.

Abstract
BACKGROUND Common iliac artery aneurysms (CIAAs) are seen in 20-40% of patients with abdominal aortic aneurysms. Historically treated with sacrifice of the hypogastric artery, which can result in significant morbidity related to pelvic ischemia, new devices have made hypogastric artery preservation more feasible but are only applicable to a small subset of aneurysm anatomy. We sought to assess the safety and efficacy or a novel technique for hypogastric artery preservation applicable to a wider variety of patients with CIAAs. METHODS We conducted a retrospective review of a prospectively maintained database of all patients with CIAAs treated with a novel endovascular technique at the UC San Diego Sulpizio Cardiovascular Center or the San Diego Veterans Affairs Hospital between March 2016 and December 2017. The endovascular technique involved stent placement in both the internal and external iliac arteries, with balloon expansion to minimize gutters between the endografts. Primary end points included technical success, limb patency, and presence of endoleaks (ELs). RESULTS A total of 14 limbs (12 patients) were treated for CIAAs with 100% technical success and limb patency at an average of 6.8 months of follow-up. No patients experienced type I or type III ELs or evidence of pelvic ischemia. Two patients required reintervention, and one patient died of causes unrelated to the procedure. CONCLUSIONS This technique was performed with excellent short- and mid-term safety in patients with varying aneurysm anatomy. The high rates of technical success and low rate pelvic ischemia represent improvement over conventional techniques that sacrifice the hypogastric artery and warrant further testing in a larger patient series with longer term follow-up.

Abstract
OBJECTIVES A type Ib endoleak (T1bEL) is a postoperative complication that usually requires additional interventions following endovascular aortic aneurysm repair. Previous studies have focused on iliac artery tortuosity or common iliac artery (CIA) diameter. However, we investigated the various risk factors for early and late T1bELs more comprehensively. METHODS This retrospective case-control study of a prospectively maintained database compared anatomical, demographic and technical factors between patients with early or late T1bELs and a control group. Early T1bEL was defined as a T1bEL occurring within 6 months of endovascular aneurysm repair (EVAR), while late T1bEL was defined as a T1bEL, initially identified more than 6 months after EVAR. Anatomical values including neck diameter, length, and angle; maximum sac diameter and length; CIA length, diameter, and tortuosity; and distal sealing length were measured and included in the analysis. We performed uni- and multivariable analyses using logistic regression and Cox proportional hazard models. RESULTS This study included 635 iliac limbs of 383 patients. Overall, T1bELs occurred in 22 iliac limbs during the follow-up period (22/635, 3.5%). Among them, the early and late T1bEL groups each included 11 limbs. The median follow-up duration of the 383 patients was 23 (8-58) months, and in the early T1bEL and early control groups, the durations were 15 (9-35) and 29 (15-60) months, respectively (P = 0.01). The median overall follow-up durations in the late T1bEL and late control groups were 87 (76-102) and 62 (48-80) months, respectively (P = 0.01). The median follow-up duration until the occurrence of late T1bEL was 44 (32-82) months, which was shorter than that of the late control group (P = 0.03). No significant differences in sex, age, or brand of stent-graft were observed between the T1bEL and control groups. In the multivariable analysis, patients in the early T1bEL group had significantly more tortuous and short CIAs, and short distal sealing lengths (P = 0.02, P = 0.04, P = 0.03, respectively), and the late T1bEL group had significantly larger maximum aortic aneurysm sac diameters, short CIAs and short distal sealing lengths (P < 0.001, P = 0.02, P = 0.002, respectively). The suspected mechanisms of the T1bELs were CIA dilatation with or without sac expansion and aggravation of sac angulation. Except for one patient with aortic dissection, T1bELs were treated with iliac limb extensions. CONCLUSIONS The various mechanisms of T1bELs differed depending on the time of onset from the procedure. An extensive sealing length may be protective against T1bEL, especially when the size of the aortic aneurysm sac is large or when the CIA has risky features, including large diameter or short length. Careful preoperative consideration of aortic aneurysm size and CIA length and tortuosity is essential, and patients with risky features should undergo strict postoperative surveillance.

Abstract
Purpose: To compare and contrast the midterm outcomes of the E-liac and Zenith (ZBIS) iliac branch devices (IBDs) for the preservation of the internal iliac artery (IIA) in aneurysms involving the iliac bifurcation. Materials and Methods: Between January 2014 and December 2018, 84 consecutive patients (median age 74 years; 76 men) were electively treated with the E-liac (n=44) or ZBIS (n=40) IBDs and were retrospectively analyzed to evaluate the technical success, patency, need for reintervention, and mortality associated with these devices. Results: Technical success was achieved in 95 of 99 implantations (95.9%) without any statistically significant difference between the groups (93.7% vs 98.0%, p=0.114). During the first 30 days, 3 occlusions in the ZBIS group and 1 in the E-liac group were identified. There was 1 perioperative death in the ZBIS group. The median follow-up was 37 months for the ZBIS group and 28 months for the E-liac group (p=0.657). Six patients from the ZBIS group and 7 from the E-liac group were lost to follow-up. Among the remaining, there were 2 further deaths recorded, 1 in each group. Four further reinterventions in the E-liac group and 2 in the ZBIS group were performed during follow-up. The Kaplan-Meier estimates of freedom from reintervention were 87.2% (95% CI 82.6% to 90.2%) for the ZBIS group and at 86.0% (95% CI 83.7% to 89.1%) for the E-liac group (p=0.563); the freedom from occlusion estimates were 89.7% (95% CI 85.8% to 94.5%) and 95.3% (95% CI 92% to 98.7%; p=0.317), respectively. Conclusion: The E-liac and the ZBIS IBDs showed equally high technical success, midterm patency, and low reintervention rates.

Abstract
PURPOSE To analyze the results of endovascular repair of common iliac artery (CIA) aneurysms without preemptive coil embolization of the internal iliac artery (IIA). MATERIALS AND METHODS Between January 2010 and July 2016, 79 patients (mean age 74.3±8.4 years; 76 men) underwent endovascular repair extending into the external iliac artery owing to a CIA aneurysm. The procedure was performed for a ruptured aneurysm in 22 (28%) patients. Eighty-one IIAs were intentionally covered. The median CIA diameter was 37 mm (range 20-90). The primary outcomes were the occurrence of type II endoleaks and the incidence of buttock claudication. RESULTS Five (6%) patients died within 30 days (4 with ruptured aneurysms and 1 elective case). Two type II endoleaks originating from a covered IIA were recorded; one required an endovascular intervention because of aneurysm growth. The other patient died of a rupture based on an additional type III endoleak. Mean follow-up was 37.6±26.3 months. Nineteen (26%) patients required a secondary intervention. Buttock claudication was reported in 21 (28%) of 74 patients and persisted after 1 year in 7. No severe ischemic complications as a result of IIA coverage were recorded, and no revascularization was required during follow-up. CONCLUSION Treatment of CIA aneurysms by overstenting the IIA without preemptive coil embolization is safe and has a low risk of type II endoleak and aneurysm growth. Persisting buttock claudication is rare.

Impact of Compliance with Anatomical Guidelines of "Bell-Bottom" Iliac Stent Grafts for Ectatic or Aneurysmal Iliac Arteries. Cardiovasc Intervent Radiol 2020; 43:1143-1147. [PMID: 32409997 DOI: 10.1007/s00270-020-02489-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 04/09/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVE To evaluate the impact of compliance with anatomical guidelines on outcomes of endovascular aortic aneurysm repair using "bell-bottom" stent grafts (BBSGs). METHODS This is a retrospective review from January 1999 to May 2012 of patients who underwent endovascular infrarenal abdominal aneurysm repair and whose iliac limbs were greater than 18 mm in diameter. Computed tomography angiography was utilized for compliance with anatomical guidelines as stated in manufacturer's instructions for use (IFU). The primary outcome observed was iliac limb events. The secondary outcome observed was the need for re-intervention due to BBSG failure. RESULTS Of the 376 BBSGs, 55 (15%) in 27 patients met IFU. Aneurysm exclusion was achieved in all patients. The mean follow-up was 44 ± 30 months. Twenty-eight patients (11%) had 29 iliac limb events (12 type 1b endoleaks, 4 aneurysm sac growth, 4 stenosis/kink, 4 retrograde migrations, 2 component separations, 2 ruptures and 1 limb occlusion); all among patients treated outside of IFU (p < 0.04). The rate of aneurysm sac enlargement was similar between both groups, at 56%, respectively, between those treated within and those treated outside of IFU. On multivariate regression analysis, larger common iliac artery (CIA) (HR 1.088, 95% CI 1.016-1.166, p = 0.016), greater CIA tortuosity (HR 2.352, 95% CI 1.004-5.509, p = 0.048) and limbs with more than two characteristics that did not meet IFU criteria (HR 3.84, 95% CI 1.15-12.83, p = 0.03) were associated with higher rates of BBSG events and re-interventions. CONCLUSIONS BBSGs effectively seal ectatic CIAs. But rates of iliac limb events and re-interventions are higher among patients who do not meet IFU criteria. The larger CIA diameter, the greater CIA tortuosity and more than two criteria not met by IFU were associated with BBSG failure and re-intervention.

Abstract
OBJECTIVE The bell-bottom technique is a widely used technique to treat aortoiliac aneurysms with preservation of the hypogastric arteries. The published data are scarce with conflicting results regarding the evolution. The aim of this study was to compare the outcomes of patients submitted to endovascular abdominal aortic aneurysm repair with standard technique (S-EVAR) versus bell-bottom technique. METHODS This retrospective cohort study compared the outcomes of standard endovascular aneurysm repair (<16 mm iliac limbs) and bell-bottom technique (≥16 mm iliac limbs) in a tertiary vascular center between 2010 and 2015. The end points of this study were type IB endoleak, reintervention and 30-day mortality. The follow-up protocol included CT scans within 30 days of implantation and 12 months. Duplex ultrasound was performed yearly thereafter. RESULTS Two hundred and three patients were treated with bell-bottom technique (n = 84, mean age 72.2 ± 8.9) and S-EVAR (n = 119, mean age 72.7 ± 8.4). The overall 30-day mortality was 1.9%, with no significant difference between groups. There was higher prevalence of coronary heart disease in the bell-bottom technique group compared to the S-EVAR group (41.6% vs. 18.4%, p < 0.01). One patient in the S-EVAR group (0.85%) and four patients in the bell-bottom technique (4.6%) developed type IB endoleak. The mean follow-up period was 35.2 ± 30.4 months. By Kaplan-Meier analysis, freedom from type IB endoleak in 80 months was 85.2% in the bell-bottom technique group and 98.7% in the S-EVAR group (p = 0.05). The freedom from reintervention in 80 months was 74.0% in the bell-bottom technique group and 94.1% in the S-EVAR group (p = 0.6). CONCLUSIONS This study shows lower freedom from type IB endoleak in the bell-bottom group compared to the standard repair group. There is no significant difference in reoperation rate and 30-day mortality.

The Use of Iliac Branched Devices in the Acute Endovascular Repair of Ruptured Aortoiliac Aneurysms. Ann Vasc Surg 2020; 67:171-177. [PMID: 32205247 DOI: 10.1016/j.avsg.2020.02.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 02/03/2020] [Accepted: 02/16/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND The objective of this study was to evaluate the feasibility and midterm outcomes of iliac branch devices (IBDs) to preserve the internal iliac artery perfusion in emergent endovascular repair of ruptured aorto-iliac aneurysms. METHODS Between December 2012 and July 2017, a total of 8 IBDs were implanted in 6 patients (the median age 65 years; all men) in a single tertiary referral center. The indication for IBD implantation was a ruptured abdominal aortic aneurysm with a concomitant common iliac artery aneurysm (n = 4) or isolated CIA aneurysms (n = 2). The main outcome measures were technical and clinical success. The secondary outcomes were primary and primary assisted patency, the occurrence of type I/III endoleaks, and reinterventions. RESULTS All patients were hemodynamically stable during the procedures, which were performed under local anesthesia. Technical success was achieved in all cases (the median total procedure time of 188 min and the median IBD procedure time of 28 min). The median follow-up was 34 months (interquartile range 19-78). There were no deaths during the follow-up and no major complications unrelated to the IBD. Two (25%) secondary interventions were performed for IBD occlusion in patients with bilateral IBDs. The other reintervention was a type II endoleak embolization in 1 of these 2 patients. The freedom from reintervention estimate was 75% through 2 years. The overall primary assisted patency was 100% through 3 years. CONCLUSIONS The use of IBDs in the acute setting is feasible to exclude ruptured aortoiliac aneurysms while maintaining pelvic circulation. The secondary intervention rate is considerable; however, the midterm assisted primary patency rates are promising. Further studies are needed to guide patient selection and to evaluate longer term outcomes.

Abstract
AIMS The coverage / occlusion of internal iliac artery (IIA) during endovascular treatment of aorto-iliac aneurysms (AIA) can be associated with risk of ischemic complications. To reduce these complications, unilateral or bilateral iliac branch device implantation (IBDI) has been reported. This study aims at evaluating the efficacy of simultaneous unilateral IBDI in the treatment of AIAs and comparing our results with literature. MATERIALS AND METHODS From March 2010 to December 2019, 27 patients (25 men, 2 women, range 54-84 years) were treated for aorto-iliac/isolated common iliac aneurysms with simultaneous unilateral revascularization of IIA and surgical / endovascular occlusion of contralateral IIA. 27 iliac-branched devices were implanted in 27 patients. The results including ischemic complications were evaluated and compared with literature. RESULTS The technical success was 100% with no perioperative mortality and morbidity of 3.7%. Primary internal iliac branch patency at a median follow-up of 52 months (range 1-118 months) was 96.42%. Secondary endoleak was observed in 6 patients (Type 1a [1], Type 1b [1], Type II [4]) and inflammatory complication in 1 patient. The incidence of buttock claudication one year after the procedure was 11.1%. Except for buttock claudication no other ischemic complications occurred. CONCLUSION Unilateral flow preservation in the IIA territory using IBDI is associated with a lesser, but a certain risk of ischemic complications. Bilateral IBDI with bilateral flow preservation of IIAs increases the complexity, procedure -/ fluoroscopy times, contrast agent volume and cost, however, may further reduce these ischemic complications.

Abstract
BACKGROUND The factors influencing common iliac artery aneurysm (CIA) growth are not fully known. Intraluminal thrombus (ILT) has been studied as a marker of growth in abdominal aortic aneurysms (AAA), but its role in CIAs is unknown. This study aims to examine the factors associated with growth of CIAs coexistent with AAA using serial cross-sectional imaging (CT and MRI) with multiplanar reconstruction (MPR). METHODS Patients with synchronous AAA and CIA observed at contrast-enhanced CT or MRI were included. The maximal diameters of both CIA and AAA were measured using MPR. Correlation of the baseline aneurysm diameter and growth rate between CIA and AAA was evaluated. Multivariate regression analysis was used to investigate the factors associated with CIA growth. RESULTS Seventy-five AAA patients (age 74±9 years; all male) with 100 CIAs were followed for an average of 2.2±1.2 years. CIA and AAA growth were positively correlated (r=0.39, P<0.001). Multivariate analysis showed that CIA baseline diameter, AAA baseline diameter, and smoking were positively related to CIA growth. In 2-3 cm CIAs (n=59), ILT tends to be an independent predictor of AAA growth (P=0.076), and CIAs with ILT grow at more than twice the rate of CIAs without ILT (1.7 vs. 0.8 mm/year, P=0.036), despite similar baseline diameters. CONCLUSIONS CIA baseline diameter, coexisting AAA baseline diameter, and smoking are associated with CIA growth. In CIAs measuring 2-3 cm, the presence of ILT is associated with faster growth, and should be taken into account when determining surveillance intervals and timing of intervention for patients being considered for AAA repair.

Abstract
BACKGROUND Although the use of aneurysmal common iliac artery (CIA) as the landing zone during endovascular aortic aneurysm repair EVAR remains an essential procedure, this procedure may increase the risk of late complications such as ongoing CIA dilatation and type Ib endoleak (CIA-related complications). We hypothesized that incomplete sealing of the aneurysmal CIA segment during EVAR could increase the incidence of CIA-related complications. In this study, we evaluated the midterm results of EVAR with aneurysmal CIA used as the landing zone and assessed the importance of distal sealing in this procedure. METHODS We retrospectively reviewed all cases of endovascular aneurysm repair using CIA as landing zone between 2007 and 2015 that had at least 3 years' follow-up. We defined aneurysmal CIA as maximum diameter ≥18 mm. The main outcome was the incidence of CIA-related complications. We compared midterm results between normal CIA and aneurysmal CIA. Next, we analyzed risk factors for CIA-related complications in aneurysmal CIA. RESULTS Four complications occurred in normal CIA (mean follow-up, 66.5 ± 22.1 months); 21 occurred in aneurysmal CIA (mean follow-up, 62.2 ± 20.5 months). The 5-year portion of freedom from CIA-related complications was 97.3% in normal CIA and 69.4% in aneurysmal CIA (P < 0.001). Multivariable analysis in aneurysmal CIA showed that unsealed CIA segment length was only risk factor for CIA-related complications. Given the receiver operating characteristic curve results, we defined the unsealed CIA segment ≥10 mm as incomplete sealing. The hazard ratio for incomplete sealing associated with CIA-related complications was 3.92 (95% confidence interval 1.62-9.46, P = 0.02). CONCLUSIONS Use of aneurysmal CIA as landing zone increases the risk of CIA-related complications. However, maximum sealing of the aneurysmal CIA segment could prevent these complications.

Abstract
INTRODUCTION The feasibility of endovascular aneurysm repair (EVAR) is often challenged by the concurrent presence of common iliac artery aneurysms, which prevent the attainment of a successful distal sealing. The present review aims to portray the safety and efficacy of two internal iliac artery (IIA) preservation strategies in the endovascular treatment of aortoiliac aneurysms: the iliac branch extension device (IBED) and the parallel graft - "sandwich" technique (PG-ST). EVIDENCE ACQUISITION A comprehensive literature review was conducted to identify publications on endovascular treatment of iliac aneurysmal disease using IBED or PG-ST. Primary endpoints were freedom from endoleak, IIA branch occlusion and secondary interventions. EVIDENCE SYNTHESIS Twenty-eight studies were selected for analysis describing a total of 1316 patients, 1169 in the IBED group and 147 in the PG-ST group. The technical success rates were akin for IBED and PG-ST (83.9-100% versus 81.3-100%). The defined primary endpoints were reported by fourteen articles. Freedom from endoleak, IIA branch occlusion and reintervention, at 6 months, were as follows: 82-100% versus 86%, 90-94% versus 88%, and 90-98% versus 87%, respectively for IBED and PG-ST. Later outcomes were only recorded in the IBED group, and freedom from endoleak, IIA branch occlusion and reintervention, at 9 years, were 83%, 81-90%, and 64-75%, respectively. CONCLUSIONS Both IBED and PG-ST have proven to be safe and valid approaches. However, while IBED has established as a durable procedure, mid-term data lacks on PGs performance and further studies are required to attest durability of the latter procedure.

Endovascular Repair of Aortoiliac or Common Iliac Artery Aneurysm Using the Lifetech Iliac Bifurcation Stent Graft System: A Prospective Multicenter Clinical Study. Ann Vasc Surg 2019; 63:136-144. [PMID: 31563658 DOI: 10.1016/j.avsg.2019.06.048] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Revised: 06/25/2019] [Accepted: 06/30/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Sacrifice of the internal iliac artery (IIA) may result in ischemic manifestations after aortoiliac aneurysm (AIA) or common iliac artery aneurysm (CIAA) endovascular repair. This study sought to evaluate the safety and efficacy of a new Iliac Bifurcation Stent Graft (IBSG; Lifetech Scientific, Shenzhen, China) system for revascularization of the IIA. METHODS Patients who underwent implantation of the IBSG at 8 centers in China from September 2015 to June 2018 were enrolled. Clinical and computed tomography angiography follow-up assessments were conducted at 30 and 180 days postoperatively. The primary end point was the IIA patency rate of the IBSG device at 180 days postoperatively. Secondary end points comprised the postoperative technical success rate and clinical success rate at 30 and 180 days. Descriptive statistics and the Clopper-Pearson exact method were used to analyze the data. RESULTS Seventy-three patients (mean age, 69.6 years; 91.8% men) were eligible for this trial, and 59 patients were eligible for primary effectiveness end-point analysis. AIA was present in 55 patients (75.34%) and CIAA in 18 patients (24.66%). The iliac artery aneurysms were unilateral in 69 patients (94.52%) and bilateral in 4 patients (5.48%). Overall technical success was 89.04% (65 of 73 patients). IIA patency at 180 days was 96.61% (57 of 59 patients). Sexual dysfunction occurred in 1 patient (1.69%), and 2 patients (3.39%) experienced buttock claudication. There was no mortality, type III endoleak, stent migration, kinking, or fracture during the procedure and follow-up. CONCLUSIONS The IBSG implantation system is a safe and effective technique for IIA preservation during AIA or CIAA endovascular repair. The high technical success rate, IIA patency rate, and low complication rate are promising. Follow-up will be continued for 5 years to confirm the durability of the device.
