Ann Vasc Surg 2024; 106:289-296. [PMID: 38830448 DOI: 10.1016/j.avsg.2024.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 03/08/2024] [Accepted: 03/12/2024] [Indexed: 06/05/2024]
Abstract
BACKGROUND Considering a patient's anatomy and vascular conditions, aorto-femoral bypass is a treatment approach for the open repair of abdominal aortic aneurysms. This study aimed at evaluating changes in the remnant iliac artery and their correlation with the preservation state of retrograde flow from femoral anastomosis. METHODS Of 221 patients who underwent abdominal aortic aneurysm surgery between 2007 and 2022 in Pusan National University Hospital, 29 patients who underwent aorto-femoral bypass were included in this retrospective cohort study. Of these patients, 21 underwent aortobifemoral bypass and 8 underwent aortoiliac-and-femoral bypass. The change in size of the iliac artery from preoperative to postoperative and whether this difference in size depended on the status of postoperative retrograde flow were investigated. Additionally, factors affecting overall mortality and ischemic complications were identified. RESULTS The median duration from operation to the last follow-up was 2069.5 days (about 5.7 years). The average age of the patients was 78.1 years, and the proportion of males was 75.9%. In cases of disappearance of postoperative retrograde flow from the femoral anastomosis, the postoperative iliac artery size was significantly reduced compared to its preoperative size (18.4 ± 18.9 mm vs. 13.2 ± 7.9 mm, respectively; P = 0.04). The group with maintained retrograde flow had significantly larger residual common iliac artery size than the group with disappearance of flow. (20.0 ± 28.0 mm vs. 14.6 ± 8.5 mm, respectively; P = 0.02). Disappearance of retrograde flow was a significant factor in the iliac artery size reduction after surgery (odds ratio, 2.5; 95% confidence interval, 1.9-5.3; P = 0.02). Three patients with maintained retrograde flow (18.8%) required intervention owing to an increase in the size of the iliac artery. The factors that significantly influenced overall death as analyzed by Cox proportional hazard regression were chronic obstructive pulmonary disease (hazard ratio, 36.8; 95% confidence interval, 1.6-870.0; P = 0.03), peripheral arterial occlusive disease (hazard ratio, 12.7; 95% confidence interval, 1.4-115.8; P = 0.02), and disappearance of retrograde flow (hazard ratio, 8.7; 95% confidence interval, 1.2-63.9; P = 0.03). CONCLUSIONS Among the open repair methods for abdominal aortic aneurysms, if retrograde flow was not maintained through femoral anastomosis when aorto-femoral bypass was performed, the size of the remaining iliac artery decreased. However, loss of retrograde flow increased long-term mortality. When aorto-femoral bypass is performed, regular imaging follow-up is necessary at appropriate intervals to check the remnant iliac artery and retrograde flow.

Abstract
A case of a young patient with incidental bilateral internal iliac artery aneurysms and common iliac artery aneurysms is described. A staged hybrid surgical approach was performed to preserve pelvic perfusion, with bilateral stent grafts deployed into an ipsilateral anterior division branch and contralateral posterior division branch of the internal iliac arteries. One week later, an open infrarenal aorto-bi-iliac graft was performed with distal anastomoses to the previously deployed stent grafts. The findings from the present case add to the growing number of reported cases of hybrid repair of bilateral internal iliac and common iliac artery aneurysms with preservation of pelvic perfusion.

Abstract
Successful endovascular aneurysm repair can be achieved with favorable aortic and iliac arterial anatomies. However, patients with challenging iliac anatomy, such as stenotic, calcified, tortuous arteries, or concomitant iliac artery aneurysms, are commonly encountered. Such a hostile iliac anatomy increases the risk of intraprocedural complications and worsens long-term outcomes. This review addresses various technical options for treating patients with a hostile iliac anatomy, including innovative endovascular solutions, physician-modified endografts, and hybrid procedures. These considerations demonstrate the wide scope of therapies that may be offered to patients with an unfavorable iliac anatomy.

Abstract
Background Open abdominal aortic aneurysm (AAA) repair can lead to sexual dysfunction (SD) in men. Objectives To determine the prevalence of SD following open AAA repair, explore whether surgical techniques for aortic reconstruction can have a differential impact on the occurrence of SD, and summarize current knowledge in this field. Methods Retrospective review of 100 patients submitted to open AAA repair between 1995 and 2010 in a quaternary center. Sexual dysfunction was assessed according to questions from the modified International Index of Erectile Function (IIEF), considering the condition before surgical repair and 3 months after surgery. The chi-square test, Fisher's exact test, and Student's t test were used for statistical analyses. Results 100 patients were included (mean age = 66.4 years old). Normal sexual activity, no sexual activity, erectile dysfunction, and retrograde ejaculation with preserved erectile function were found in 36%, 21%, 18%, and 24% of patients, respectively. The group of patients with no sexual activity was older (mean age = 72.3 years old vs 64.5 years old, p < 0.001). Erectile dysfunction prevalence was higher in patients submitted to an aorto-bifemoral bypass (p = 0.032). Retrograde ejaculation was more frequent in patients submitted to an aorto-aortic bypass (p = 0.007). Conclusions Sexual function is a frequent condition intimately associated with the aortic reconstruction technique. The literature review found contradictory results regarding whether the endovascular approach is protective compared with open repair, but clearly demonstrated the importance of techniques targeting preservation of the internal iliac artery and the superior hypogastric plexus.

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
OBJECTIVE The European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy. METHODS The guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated. The recommendations are graded according to a modified European Society of Cardiology grading system, where the strength (class) of each recommendation is graded from I to III and the letters A to C mark the level of evidence. RESULTS A total of 160 recommendations have been issued on the following topics: Service standards, including surgical volume and training; Epidemiology, diagnosis, and screening; Management of patients with small abdominal aortic aneurysm (AAA), including surveillance, cardiovascular risk reduction, and indication for repair; Elective AAA repair, including operative risk assessment, open and endovascular repair, and early complications; Ruptured and symptomatic AAA, including peri-operative management, such as permissive hypotension and use of aortic occlusion balloon, open and endovascular repair, and early complications, such as abdominal compartment syndrome and colonic ischaemia; Long term outcome and follow up after AAA repair, including graft infection, endoleaks and follow up routines; Management of complex AAA, including open and endovascular repair; Management of iliac artery aneurysm, including indication for repair and open and endovascular repair; and Miscellaneous aortic problems, including mycotic, inflammatory, and saccular aortic aneurysm. In addition, Shared decision making is being addressed, with supporting information for patients, and Unresolved issues are discussed. CONCLUSION The ESVS Clinical Practice Guidelines provide the most comprehensive, up to date, and unbiased advice to clinicians and patients on the management of abdominal aorto-iliac artery aneurysms.

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
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
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. STRUCTURE Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Mid-Term Outcomes of a Pre-Cannulated Iliac Branched Device in the Treatment of Abdominal Aortoiliac Aneurysms: A Retrospective Analysis from a Single Center. J Clin Med 2023; 12:6395. [PMID: 37835039 PMCID: PMC10573636 DOI: 10.3390/jcm12196395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 10/03/2023] [Accepted: 10/06/2023] [Indexed: 10/15/2023] Open
Abstract
The aim was to assess the mid-term results of the E-iliac branched device. Baseline and follow-up data of this monocentric retrospective cohort study including all consecutive patients with aortoiliac aneurysms treated with iliac branched devices between 2016 and 2023 were extracted from the hospital records. Preoperative and follow-up CT scans were analyzed regarding endoleaks, migration, aneurysm sac remodeling, and device patency. Overall, 50 devices were implanted in 38 patients with a median age of 69 (IQR 62-78) years, and 1.6 bridging stent grafts per vessel were implanted through transfemoral (22/50; 44%) or upper extremity access (28/50; 56%). Primary technical success and assisted technical success were 97% (37/38) and 100% (38/38), respectively. No migration, no type I or III endoleaks, no stroke, colonic ischemia, aneurysm rupture, or conversion during the early and mid-term follow-ups (11 months, IQR 5-26) were observed. Aneurysm sac enlargement or shrinkage was observed in 0% (0/38) and 16% (6/38) patients, respectively. E-iliac-related re-interventions were seen only during the early follow-up: two thrombectomies with bare-metal stent relining after thrombosis of the iliac limb. Bridging stent graft and E-iliac patency during the mid-term follow-up were 100%. E-iliac showed encouraging mid-term results in the treatment of aortoiliac aneurysms with high technical success and a low re-intervention rate.

Abstract
Congenital abnormalities of the iliac artery are uncommon and often discovered incidentally during the diagnosis or treatment of peripheral vascular diseases such as abdominal aortic aneurysm (AAA) and peripheral arterial diseases. The endovascular treatment of infrarenal AAA can be complicated by anatomic abnormalities in the iliac arteries, such as the absence of the common iliac artery (CIA) or overly short bilateral common iliac arteries. We present a case of a patient with a ruptured AAA and bilateral absence of the CIA, successfully treated by endovascular intervention combined with preservation of the internal iliac artery using the sandwich technique.

Abstract
PURPOSE We describe the feasibility and early results of a novel endovascular approach with a surgeon-modified fenestrated iliac stent graft to preserve pelvic perfusion in patients with iliac aneurysms not suitable for iliac branch devices (IBDs). TECHNIQUE Seven high-risk patients, median age 76 years (range 63-83), with a complex aortoiliac anatomy with contraindications for commercially available IBDs were treated with a novel surgeon-modified fenestrated iliac stent graft between August 2020 and November 2021. The modified device was built using an iliac limb stent graft (Endurant II Stent Graft; Medtronic), which was partially deployed, surgically fenestrated with a scalpel, reinforced, re-sheathed, and inserted via femoral access. The internal iliac artery was cannulated and bridged with a covered stent. Technical success rate was 100%. After a median follow-up period of 10 months, there was 1 type II endoleak and no migrations, stent fractures, or loss of device integrity. One iliac limb occlusion occurred after 7 months, which needed a secondary endovascular intervention, restoring patency. CONCLUSION Surgeon-modified fenestrated iliac stent graft is feasible and might be used as an alternative in patients with a complex iliac anatomy not suitable to commercially available IBDs. Long-term follow-up is needed to evaluate stent graft patency and potential complications. CLINICAL IMPACT Surgeon modified fenetrated iliac stent grafts might be a promising alternative to iliac branch devices, extending endovascular solutions to a broader patient population with complex aorto-iliac anatomies preserving antegrade internal iliac artery perfusion. It is possible to treat small iliac bifurcations and large angulations of the iliac bifurcation safely and there is no need for a contralateral or upper-extremity access.

Abstract
BACKGROUND The aim of study was to assess the safety and effectiveness of 3 different commercial iliac branch devices (IBDs): the Zenith Branch Iliac Endovascular Graft; the Gore Excluder Iliac Branch System and the E-liac Stent Graft System for the treatment of aorto-iliac or iliac aneurysms. METHODS From January 2017 to February 2020, a retrospective reviewed was conducted on a total of 96 patients. Primary endpoint was IBD instability rate at 24-months. Secondary endpoints included onset of any endoleaks, buttock claudication, IBD-related reintervention and all-death rates, post-operative acute kidney and changes in maximum diameter from baseline of the aortic aneurysmal sac. RESULTS At 24 months, the branch instability rate was similar amongst the three IBDs employed [Jotec 1/24 (4.1%), Gore 1/12 (8.3%), Cook 6/47 (12.7%), p-value = 0.502]. As well, no statistical difference in terms of branch-occlusion and branch-related endoleaks was observed. The Jotec group showed a significant decrease in maximum diameter from the baseline of the aortic aneurysmal sac when compared to the Gore group alone. No other differences were found relevant to the onset of any endoleaks, reinterventions and all-death rates. At 24-months, the Kaplan-Meier estimate of survival freedom from any branch instability was 95.8%, 91.6% and 86.8% for Jotec, Gore and Cook groups, respectively. CONCLUSIONS The use of IBDs represents a safe method for preserving patency of the IIA during treatment of aorto-iliac or iliac aneurysms providing a low rate of IBD instability.

Abstract
PURPOSE Iliac branch devices (IBD) are widely used to treat aortoiliac aneurysms with an unfit distal landing zone for standard endovascular aneurysm repair (EVAR). The aim of this retrospective study was to examine the treatment of aortoiliac aneurysms with the combination of the Endurant II(s) stent graft system (Medtronic®) and the E-liac stent graft (Artivion®). MATERIALS AND METHODS Data of all patients who underwent an EVAR combined with unilateral or bilateral IBD between January 2015 and January 2020 were analyzed. Primary outcomes were technical success at implantation (successful EVAR with IBD extension placement and patency of the grafts without type 1 or type 3 endoleak), and type 1b/3 endoleak, hypogastric artery patency and IBD-related reinterventions during follow-up. Secondary outcomes were all type 1 endoleak, all reinterventions, rupture, and mortality during follow-up. RESULTS A total of 38 patients were treated with a combination of EVAR with IBD. Technical success was 94.7% (n = 36/38). The 30-day survival was 100%. Median follow-up time was 31 months (range 8-56). During follow-up, no patients developed type 1b or type 3 endoleak and all hypogastric arteries at the side of IBD remained patent. The overall reintervention rate at 12 months follow-up was 5.3% (n = 2/38) and the IBD-related reintervention rate was 2.6% (n = 1/38). CONCLUSION The combination of the Endurant II(s) and the E-liac stent graft system is an effective and safe procedure for patients with an aortoiliac aneurysm. We confirm the high hypogastric artery patency rate using IBD. Furthermore, these devices have a high technical success rate even when it is combined with an Endurant II(s) EVAR main body.

Differences in Cardiac-Pulsatility-Induced Displacement and Geometry Changes between the Cook ZBIS and Gore IBE: Postoperative Comparison Using ECG-Gated CTA Scans. Diagnostics (Basel) 2023; 13:diagnostics13030496.

Abstract
To what extent the stentgraft design of iliac branch devices (IBDs) relates to dynamic deformation is currently unknown. Therefore, this study aimed to quantify and compare displacement and geometry changes during the cardiac cycle of two common IBDs. This paper presents a two-center trial with patients treated with a Zenith bifurcated iliac side (ZBIS) or Gore iliac branch endoprosthesis (IBE). All patients underwent a retrospective electrocardiogram (ECG)-gated computed tomographic angiography (CTA) during follow-up. Cardiac-pulsatility-induced displacement was quantified for the following locations: (neo) bifurcation of the aorta, IBD flow divider, distal markers of the internal iliac artery (IIA) component and first IIA bifurcation. Geometrical parameters (length, tortuosity index, curvature and torsion) were quantified over centerlines. Displacement was more pronounced for the IBE than the ZBIS, e.g., craniocaudal displacement of 0.91 mm (0.91-1.13 mm) vs. 0.57 mm (0.40-0.75 mm, p = 0.004), respectively. The IBDs demonstrated similar geometrical parameters in the neo-common iliac artery and distal IIA, except for the larger dynamic curvature and torsion of the distal IIA in IBEs. The IBEs showed more dynamic length and curvature change compared to the ZBIS in the stented IIA. The IIA trajectory showed more pronounced deformation during the cardiac cycle after placement of an IBE than a ZBIS, suggesting the IBE is more conformable than the ZBIS.

Abstract
BACKGROUND To determine the importance of the hypogastric artery for the outcomes of survival, endoleaks, reinterventions, buttock claudication (BC), and perioperative mortality rate (PMR) in patients with aortoiliac aneurysms (AIA) receiving endovascular or open surgical (OS) repair. METHODS This was a prospective consecutive cohort study of patients with AIA who underwent endovascular treatment or OS repair during the period of 2010-2021. Endovascular repair was performed with use of aortoiliac endoprosthesis associated with internal iliac artery (IIA) coil embolization and/or with iliac branch endoprosthesis (IBE) in order to preserve the IIA. The AIA OS repairs were performed with the artery ligation in order to exclude the IIA, or in some cases, the exclusion of the IIA was performed with an endosuture in the proximal stump of the artery. Three groups were identified in the postprocedural period: group 0 (no hypogastric arteries (HAs) preserved), group 1 (1 hypogastric artery preserved), and group 2 (2 hypogastric arteries preserved). RESULTS A total of 91 patients were submitted to OS or endovascular surgery. Regarding the HA patency, there were 17 patients in group 0, 45 patients in group 1, and 29 patients in group 2. There were 17 cases of bowel ischemia (BI) (94.1% in group 0, 5.9% in group 1, and no cases in group 2, P < 0.001) most of them in group 0, with statistical significance, 12 cases of BC (91.7% in group 0, 8.3% in group 1, and no cases in group 2, P < 0.001), most of them in group 0, with statistical significance. The perioperative mortality was 14.3%, 13 patients (9 patients - 52.9% group 0, 3 patients - 6.7% group 1, and 1 patient - 3.4% group 2, P < 0.001). The linear regression analysis for survival rates showed that BI [P = 0.026 to hazard ratio (HR) = 1.69], emergency aortoiliac repair (P < 0.001, HR = 8.86), and number of HAs (P < 0.001, HR = 5.46) in postoperative were related to poorer survival rates in both univariate and multivariate analysis. The linear regression analysis showed that the number of HAs (P < 0.001, HR = 3.61) in postoperative, emergency aortoiliac repair (P = 0.002, HR 3.233), and cardiac disease (P = 0.048, HR = 3.84) were related to BI. CONCLUSIONS In conclusion, the number of HA is crucial for adequate and safe outcomes after abdominal aortic aneurysm (AAA) repair. The main factors related to death were BI, emergency aortoiliac repair, and the number of HAs preserved. Moreover, the main factors related to BI were the number of HAs in postoperative, emergency aortoiliac repair, and cardiac disease.

Abstract
OBJECTIVE The purpose of the present study was to evaluate the technical and short-term clinical outcomes of internal iliac artery (IIA) reconstruction during endovascular aortic repair (EVAR) with in situ laser-assisted fenestration in cases of abdominal aortic aneurysm (AAA) in which the iliac artery is unfit for an internal branched device (IBD). METHODS In the present single-institution retrospective study, we analyzed patients with AAAs who had undergone EVAR with in situ laser-assisted fenestration for IIA reconstruction between January 2018 and April 2021. The study included patients with iliac artery anatomy unfit for the use of commercial IBDs. The primary safety end point was freedom from major adverse events and unplanned reinterventions within 30 days. The primary efficacy end point was freedom from IIA restenosis, reintervention, and symptoms due to pelvic ischemia at 1 year after the procedure. RESULTS A total of 20 patients requiring IIA reconstruction but with anatomy unfit for IBD placement were treated with in situ laser-assisted fenestration during EVAR for aortoiliac aneurysms during the study period. The mean age of our patients was 72 years, and 90% were men. The technical success rate was 100%. No patient had died within 30 days after the procedure. A suspicious IIA perforation had occurred in one patient, which was treated with an additional covered stent, for a primary safety end point of 95.0%. After a mean follow-up of 11 months, all except for one of the reconstructed IIAs were patent. Three patients reported symptoms of buttock claudication on the IIA occluded side at their 3-month follow-up after the procedure. However, these symptoms had subsided in two of these patients at 6 months. Type II endoleaks without sac expansion had occurred in two patients owing to retrograde blood flow from the inferior mesenteric artery and lumbar artery. Both patients were kept under close surveillance. The rate of freedom from major adverse events and unplanned reinterventions within 30 days (primary efficacy end point) was 86.3% at 1 year after procedure. CONCLUSIONS In situ laser-assisted fenestration was found to be a safe and effective alternative method for IIA reconstruction during EVAR for aortoiliac aneurysms in patients with anatomy unfit for IBD.

Internal Iliac Artery Embolization within EVAR Procedure: Safety, Feasibility, and Outcome. J Clin Med 2022; 11:jcm11247399. [PMID: 36556015 PMCID: PMC9782076 DOI: 10.3390/jcm11247399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 12/03/2022] [Accepted: 12/12/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND This study is focused on Internal Iliac Artery (IIA) embolization in patients undergoing Endovascular Aneurysm Repair (EVAR). Our aims were: to establish the feasibility of the procedure; to assess the presence of endoleak (EL) and increase in the size of the sac at follow-up; to define the need for reintervention; and to evaluate mortality rate. METHODS In this retrospective single-center study, EVAR-treated patients with an embolization of IIA were chosen. Coils and vascular plug were used as embolizing agents. RESULTS A total of 49 participants were enrolled in the study (48 men and one woman) with a median age of 76 ± 12 years. Patients had no early EL in 87.75% of cases, 8.16% had type 1a EL, 2.04% type 1b EL, and 2.04% type 2 EL, with a comprehensive technical success of 95.91%. In the follow-up, at 1 month 72.22% remained without EL, at 6 months 70.97%, and at 1 year 81.48%. In the same period, the trend of type 1 EL was 5.56% (1 month), 3.23% (6 months), and 0% (1 year). For EL type 2: 22.22% at 1 month, 25.81% at 6 months, and 16.7% at 1 year. The overall mortality was 35.58% and the re-intervention rate was 16.33%. CONCLUSIONS IIA embolization is a feasible and safe procedure. The presence of EL is not superior to EVAR procedures that do not involve embolization.

Abstract
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. Structure: Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Abstract
PURPOSE To evaluate the technical feasibility and clinical outcomes of endovascular treatment for internal iliac artery (IIA) aneurysms. MATERIAL AND METHODS This was a retrospective analysis of 25 patients with 32 IIA aneurysms (mean diameter: 39.1 ± 12.6 mm) who underwent endovascular treatment over a 10-year period, and were available for follow-up. Univariate analysis was used to determine the association between variables (including aortoiliac involvement and technique) and outcome. RESULTS The IIA inflow was covered with an iliac stent graft (N = 29) or embolized with a plug (N = 3). The IIA outflow was embolized in all but one case in which there was thrombotic occlusion of outflow branches. Outflow embolization using plugs or coils was performed in the distal IIA or anterior/posterior trunks in 9 cases and distal IIA branches in 22 cases. During a mean follow-up period of 39.9 months, 31.2% of aneurysms demonstrated endoleak and 12.5% demonstrated enlargement. Univariate analysis revealed that endoleak was associated with technical failure (p = 0.01) and that endoleak rate was higher in patients who underwent distal IIA branch embolization (p = 0.03). No variable was associated with sac expansion. Major complication occurred in one patient who died from aneurysm rupture. Minor complications were reported in six patients who developed femoral pseudoaneurysm (N = 2, 8%), buttock claudication (N = 3, 12%), and limb graft occlusion (N = 1, 4%). CONCLUSION Endovascular treatment of IIA aneurysms effectively prevents sac expansion. Endoleak was more frequently observed in cases of technical failure and those in which distal IIA branches were embolized. LEVEL OF EVIDENCE Level 3b, retrospective cohort study.

Abstract
Spinal cord ischemia can be a devastating complication after thoracoabdominal aortic surgery. We report a case of a 56-year-old woman who had undergone multiple prior thoracic aneurysm repairs with an increase of a visceral segment aneurysm to 6 cm. The aneurysm was repaired using a physician-modified four-vessel fenestrated graft and iliac branch device. Postoperatively, she developed weakness in her right leg. Computed tomography angiography showed an occluded right hypogastric artery. We proceeded with aspiration thrombectomy with complete resolution of her right leg weakness within hours postoperatively. Our findings have illustrated the important role of hypogastric arteries in the development of spinal cord ischemia.

Abstract
OBJECTIVE To report a two-centers evaluation of the effects of iliac axis tortuosity on iliac branch device (IBD) results. METHODS From 2015 to 2021, all IBD procedures performed at two European centers were analyzed retrospectively. The preoperative pelvic tortuosity index (PTI), external tortuosity index (ETI), and double iliac sign (DIS) were assessed for each iliac axis submitted to IBD. The primary endpoints were technical success, early and mid-term IBD complications (occlusion, stenosis, endoleaks [ELs]) and reinterventions, and the association with the PTI, ETI, and DIS. The 30-day mortality, survival, freedom from complications and freedom from reinterventions (FFR) were the secondary endpoints. RESULTS During the study period, 224 patients had undergone 256 IBD procedures for 165 (64.5%) aortoiliac aneurysms, 44 (17.2%) isolated iliac aneurysms, 11 (4.3%) abdominal aortic aneurysms with a short iliac landing zone, and 36 (14.1%) type Ib ELs. IBD was planned with endovascular aortic aneurysm repair for 158 (61.7%), fenestrated/branched endovascular aortic aneurysm repair for 45 (7.6%), and isolated for 53 (20.7%) cases. Technical success and 30-day mortality were 99.2% (254 of 256) and 0.9% (2 of 224), respectively. A PTI >1.4, an ETI >1.7, and the DIS were tested to identify the risk factors for the endpoints. No ELs and 9 (3.5%) IBD occlusions, requiring five reinterventions (2%), had occurred within 30 days. No association with the PTI, ETI, or DIS was identified; IBD oversizing of ≥25% on the external iliac artery was independently related to occlusion (odds ratio, 4.3; 95% confidence interval [CI], 1-18.1; P = .045). The mean follow-up was 31 ± 27 months, with 11 IBD occlusions, 14 ELs, and 21 reinterventions. At 1, 3, and 5 years of follow-up survival, IBD patency, and FFR were 95%, 89%, and 80%; 93%, 91%, and 90%; and 93%, 89%, and 83%, respectively. The risk factors for overall complications (n = 34; 13.3%) and reinterventions (n = 26; 10.2%) were an ETI >1.7 (P = .037 and P = .019), a PTI >1.4 (P = .016 and P = .012), and a type Ib EL as the indication (P = .025 and P = .001), respectively. Cox regression confirmed PTI >1.4 as an independent predictor of overall complications and reinterventions (hazard ratio [HR], 2.3; 95% CI, 1.1-4.4; P = .018; and HR, 3 95% CI, 1.3-6.8; P = .018, respectively) and ETI >1.7 as an independent risk factor for ELs (HR 6; 95% CI, 2.1-17.5; P = .001). The freedom from complications and FFR were significantly lower with a PTI >1.4 at 3 years (73% vs 92% [log-rank P = .01] and 77% vs 93% [log-rank P = .001], respectively). CONCLUSIONS We found IBDs to be safe and effective in the treatment of aortoiliac aneurysms. Early complications are uncommon and related to endograft oversizing rather than anatomic characteristics in the present study. Iliac tortuosity is a risk factor for overall complications and reinterventions, in particular for IBD-related ELs.

Abstract
BACKGROUND The GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE) is designed to treat iliac aneurysms with preservation of blood flow through the internal iliac artery (IIA). Little is known about the influence of IBE placement on the IIA geometry. This study aimed to provide detailed insights in the dynamic behavior and geometry of the common iliac artery (CIA) and IIA trajectory and how these are influenced after treatment with an IBE. METHODS Pre- and postoperative electrocardiogram-gated computed tomography angiography (ECG-gated CTA) scans were acquired in a prospective study design and analyzed with in-house written algorithms designed for aorto-iliac and endoprosthesis deformation evaluation. Cardiac pulsatility-induced motion patterns and pathlengths were computed by tracking predefined locations on the aorto-iliac tract. Centerlines through the CIA-IIA trajectory were used to investigate the static and dynamic geometry, including curvature, torsion, length and Tortuosity Index (TI). RESULTS Fourteen CIA-IIA trajectories were analyzed before and after IBE placement. Cardiac pulsatility-induced motion and pathlengths increased after IBE placement, especially at mid IIA and the first IIA bifurcation (P≤0.04). After IBE placement, static and dynamic curvature, length and TI decreased significantly (P<0.05). Furthermore, the average dynamic torsion increased significantly (P=0.030). The remaining geometrical outcomes were not statistically significant. CONCLUSIONS The placement of an IBE device stiffens and straightens the CIA-IIA trajectory. Its relation with clinical outcome is yet to be investigated, which can be done thoroughly with the ECG-gated CTA algorithms used in this study.

Abstract
OBJECTIVES The Iliac Sandwich is an off-label technique that uses parallel stent grafts to treat aortoiliac aneurysms. The purpose of this experimental study is to evaluate the conformability and juxtaposition of stent grafts combinations used in this technique through in-vitro mechanical evaluation, computed tomography (CT) analyses, and a controlled pulsatile flow system. METHODS The combinations of two Viabahn® ("V-V") or Viabahn® and Excluder® iliac extension ("V-E") were analysed using CT imaging with measurement of the gutter area by two independent analysts before and after balloon angioplasty. In a second phase, the parallel stent combinations were also evaluated using CT imaging after being implanted in the aortic aneurysm model with a pulsatile flow system with controlled temperature, viscosity, and density. RESULTS The "V-E" group had a better conformability when compared to the "V-V" group, ensuring smaller gutter areas (0.0064 cm2 ± 0.01 vs. 0.0228 cm2 ± 0.03, p < 0.001). Post dilatation with two non-compliant balloons resulted in enlargement of the gutter area (Area A, p 0.065; Area B, p 0.071). Conversely, post dilatation with a non-compliant balloon for the internal iliac component and a compliant balloon for the external iliac device reduced the gutter area (Area A, p 0.008; Area B, p 0.010). CONCLUSION The combination of Viabahn® and Excluder® iliac extension device ("V-E") had a smaller gutter area compared to two Viabahn® parallel stents for the Iliac Sandwich Technique. Post dilatation using a non-compliant balloon for the internal iliac device and a compliant balloon for the external iliac provided superior conformability and juxtaposition.

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
Adjunct internal iliac artery (IIA) procedures, such as preoperative embolisation or coverage with iliac branch extensions, are not infrequent in the context of endovascular repair of abdominal aortic aneurysms. Moreover, on many occasions, these procedures are performed in a multi-stage approach by interventional radiologists prior to the main operation. Bearing in mind the potential complications of IIA occlusion when revascularization is not initially deemed necessary, various issues arise spanning from appropriate patient counselling to medicolegal consequences. Herein, we aim to provide a roadmap regarding appropriate patient consenting, highlighting the need for multidisciplinary approach of these patients.

Ann Vasc Surg 2022; 85:204-210. [PMID: 35339601 DOI: 10.1016/j.avsg.2022.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 03/01/2022] [Accepted: 03/02/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVE The profunda femoris artery (PFA) supplies important collateral branches to both the ipsilateral internal iliac and the distal superficial femoral artery (SFA). The size and patency of these collateral pathways can determine the risk of pelvic malperfusion, spinal cord ischemia, and lower extremity limb loss following vascular interventions. Despite its importance, the anatomy of the PFA is rarely characterized in clinical studies involving the pelvic or lower extremity circulation. This discussion may be limited by the lack of a comprehensive classification system. Our objective was to describe the most common PFA anatomic variants and present a classification system based on its branching patterns. METHODS We dissected 155 fixed and non-fixed femoral artery systems from 88 cadavers. Seventy-seven female and 78 male femoral exposures were performed. Vessel diameters, branch configurations and relative distances between the inguinal ligament, PFA, lateral circumflex femoral artery (LCFA), and medial circumflex femoral artery (MCFA) were recorded. RESULTS The mean diameters of the common femoral artery, SFA and PFA in males were 10.3mm, 8.0mm and 6.9mm, and 8.9mm, 6.9mm and 6.1 in females, respectively (p < 0.05). The mean distances from the inguinal ligament for PFA, MCFA and LCFA were 41mm, 41.7mm and 52.5mm respectively. No significant differences were noted relative to laterality or fixation. We developed a clinically applicable classification system based on the orientation of the PFA, LCFA, and MCFA. Six PFA, 5 LCFA and 5 MCFA variations were identified and ranked by frequency. The five most common combinations accounted for 56.1% of our cadaver series. CONCLUSION The anatomic orientation of the PFA and its branches is highly variable. We propose a novel classification system of this rich collateral system to facilitate consistent communication in academic and clinical vascular surgery.

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.

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.

Abstract
OBJECTIVE Open or endovascular repair of abdominal aortic aneurysms may involve the sacrifice of the internal iliac artery. The effect of internal iliac artery exclusion on ischemic complications and overall mortality was investigated. METHODS Data of 326 patients who underwent elective open surgical or endovascular treatment for a non-ruptured abdominal aortic aneurysm between January 2010 and December 2019 in a tertiary hospital were retrospectively reviewed. Ischemic complications included buttock claudication and spinal ischemia, including paraparesis, ischemic colitis, lower limb paresthesia, and skin necrosis. Their duration and mortality during this period were investigated. RESULTS Nearly 50% of patients (148; 45.4%) underwent endovascular aortic repair and 178 (54.6%) underwent open surgery. The median patient age was 78.00 years (range: 31-94 years). The median follow-up period was 1,140 days (range: 0-4,757 days). A total of 50 patients (15.3%) died during follow-up. Bilateral internal iliac arteries were preserved in 187 patients (57.4%); a single internal iliac artery was preserved in 86 patients (26.4%), and no internal iliac artery was preserved in 53 patients (16.3%). Ischemic complications occurred in 57 patients (17.5%). According to the multivariable analysis, failure to preserve bilateral internal iliac arteries (hazard ratio: 8.65, 95% confidence interval: 4.31-17.36, p<0.01), management of the internal iliac artery (hazard ratio: 3.05, 95% confidence interval: 2.17-4.28, p<0.01), and hyperlipidemia (hazard ratio: 2.09, 95% confidence interval: 1.04-4.17, p=0.04) affected ischemic complications. Further, according to the univariable analysis, patients experienced more ischemic complications when a single (hazard ratio: 6.97; 95% confidence interval: 3.74-13.02; p<0.01) or none of the internal iliac arteries were preserved (hazard ratio: 8.88; 95% confidence interval: 4.12-19.16; p<0.01) than when both internal iliac arteries were preserved. Moreover, according to the multivariable analysis, stage 5 chronic kidney disease (hazard ratio: 2.7, 95% confidence interval: 1.09-6.14, p=0.03), age > 75 years (hazard ratio: 2.48, 95% confidence interval: 1.12-5.49, p=0.03), cerebrovascular accident (hazard ratio: 1.95, 95% confidence interval: 1.00-3.78, p=0.05), and failure to preserve bilateral internal iliac arteries (hazard ratio: 1.91, 95% confidence interval: 1.02-3.46, p=0.04) were associated with higher mortality rates following abdominal aortic aneurysm repair. CONCLUSIONS Internal iliac artery exclusion is a risk factor for ischemic complications and overall mortality. Regarding abdominal aortic aneurysm repair, preservation of the internal iliac artery as much as possible is recommended.

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.

Prior Infrarenal Aortic Surgery is Not Associated with Increased Risk of Spinal Cord Ischemia Following Thoracic Endovascular Aortic Repair and Complex Endovascular Aortic Repair. J Vasc Surg 2021; 75:1152-1162.e6. [PMID: 34742886 DOI: 10.1016/j.jvs.2021.10.028] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 10/10/2021] [Indexed: 01/16/2023]
Abstract
OBJECTIVES Patients with prior infrarenal aortic intervention represent an increasing demographic of patients undergoing thoracic endovascular aortic repair (TEVAR) and/or complex EVAR. Studies have suggested that prior abdominal aortic surgery is a risk factor for spinal cord ischemia (SCI). However, these results are largely based on single-center experiences with limited multi-institutional and national data assessing clinical outcomes in these patients. The objective of this study was to evaluate the effect of prior infrarenal aortic surgery on SCI. METHODS The Society for Vascular Surgery Vascular Quality Initiative database was retrospectively reviewed to identify all patients ≥18 years old undergoing TEVAR/complex EVAR from January 2012 to June 2020. Patients with previous thoracic or suprarenal aortic repairs were excluded. Baseline and procedural characteristics and postoperative outcomes were compared by group: TEVAR/complex EVAR with or without previous infrarenal aortic repair. The primary outcome was postoperative SCI. Secondary outcomes included postoperative hospital length of stay (LOS), bowel ischemia, renal ischemia, and 30-day mortality. Multivariate regression was used to determine independent predictors of postoperative SCI. Additional analysis was performed for patients undergoing isolated TEVAR. RESULTS A total of 9506 patients met the inclusion criteria: 8691 (91.4%) had no history of infrarenal aortic repair and 815 (8.6%) had previous infrarenal aortic repair. Patients with previous infrarenal repair were older with an increased prevalence of chronic kidney disease (p=0.001) and cardiovascular risk factors including hypertension, chronic obstructive pulmonary disease, and smoking history (p<0.001). These patients presented with larger maximal aortic diameters (6.06±1.47 cm versus 5.15±1.76 cm; p<0.001) and required more stent grafts (p<0.001) with increased intraoperative blood transfusion requirements (p<0.001), and longer procedure times (p<0.001). Univariate analysis demonstrated no difference in postoperative SCI, postoperative hospital LOS, bowel ischemia, or renal ischemia between the two groups. Thirty-day mortality was significantly higher in patients with prior infrarenal repair (p=0.001). On multivariate regression, prior infrarenal aortic repair was not a predictor of postoperative SCI, while aortic dissection (odds ratio [OR] 1.65; 95% confidence interval [CI] 1.26-2.16, p<0.001), number of stent grafts deployed (OR 1.45; 95% CI 1.30-1.62, p<0.001), and units of packed red blood cells transfused intraoperatively (OR 1.33; 95% CI 1.03-1.73, p=0.032) were independent predictors of SCI. CONCLUSIONS Although TEVAR/complex EVAR patients with prior infrarenal aortic repair constituted a sicker cohort with higher 30-day mortality, the rate of SCI was comparable to patients without prior repair. Previous infrarenal repair was not associated with risk of SCI.

Abstract
PURPOSE The purpose of this study was to compare outcomes of internal iliac artery (IIA) stenting using balloon-expandable (BESG) or self-expandable stent grafts (SESG) during endovascular repair of aortoiliac aneurysms with iliac branch endoprosthesis (IBE; W. L. Gore, Flagstaff, Ariz). METHODS We retrospectively reviewed all consecutive patients treated for aortoiliac aneurysms using IBE between 2014 and 2020. IIA stenting was performed using either the IIA side branch SESG or a Gore VBX BESG (W. L. Gore). Indications for use of BESGs were "up-and-over" IBE technique for type IB endoleak after prior endovascular aortic aneurysm repair (EVAR), short IIA length, and need for IIA extension into divisional branches (outside instructions for use). End points included technical success, freedom from buttock claudication, primary IIA patency, and freedom from IIA branch instability (eg, branch-related death or rupture, occlusion, disconnection, or reintervention for stenosis, kink, or endoleak), freedom from type IC/IIIC endoleak, and freedom from secondary interventions. RESULTS There were 90 patients (86 males and 4 females) with a mean age of 74 ± 7 years treated by EVAR with 108 IBEs. Choice of stent was BESG in 43 and SESG in 65 targeted IIAs. BESGs were used more frequently in patients with prior EVAR (22% vs 2%; P = .003,), isolated IBEs (31% vs 2%; P < .001), and in patients with IIA aneurysms requiring stenting into divisional branches (36% vs 5%; P < .001). Technical success was similar for BESGs and SESGs (97% vs 100%; P = .40), respectively. The mean follow-up was 25 ± 16 months (range, 11-34 months). At 2 years, freedom from buttock claudication was 100% for BESG and 95 ± 3% for SESG (Log-rank 0.26), with no difference in primary patency (BESG, 100% vs SESG, 94 ± 4%; Log-rank 0.94). There were four (9%) IIA-related endoleaks in the BESG group and one (2%) in the SESG group (P = .08). Freedom from IIA branch instability was 87 ± 6% for BESG and 96 ± 3% for SESG at 2 years (Log-rank 0.043). Freedom from type IC/IIIC endoleak was 87 ± 7% for BESG and 98 ± 2% for SESG at the same interval (Log-rank 0.06). There was no difference in freedom from reinterventions for BESG and SESG (92 ± 6% vs 98 ± 2%; Log-rank 0.34), respectively. CONCLUSIONS BESGs were used more frequently during IBE procedures indicated for failed EVAR, isolated common iliac aneurysms, and IIA aneurysms requiring extension into divisional branches. Despite these differences and BESG being used outside instructions for use, both stent types had similar primary patency, freedom from buttock claudication, and freedom from reinterventions. However, BESGs were associated with higher rates of IIA-related branch instability.

Abstract
Revascularization of the internal iliac artery during open repair of aortoiliac aneurysms can be challenging, especially if there is a significant distance between the orifices of the internal and external iliac arteries owing to common iliac aneurysmal dilatation. We describe a technique involving insertion of an 18-mm tube graft between the proximal aortic neck and aneurysmal common iliac artery bifurcation. Revascularization of the contralateral external iliac artery is accomplished through an 8-mm side arm graft.

Ann Vasc Surg 2021; 77:38-46. [PMID: 34455041 DOI: 10.1016/j.avsg.2021.05.065] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Revised: 05/08/2021] [Accepted: 05/31/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Endovascular treatment of complex common iliac artery (CIA) and internal iliac artery (IIA) aneurysms using iliac branch endoprostheses (IBE) has proven safe and effective. Instructions for use (IFU) require deployment of current IBE technology with the corresponding manufacturer's modular bifurcated aortic endograft. Concomitant aortoiliac occlusive disease, inadequate renal artery-iliac bifurcation length, and unfavorable aortic anatomy preclude on-label IBE deployment. This study aimed to evaluate the technical feasibility and safety of Alternative Endograft Aortoiliac Reconstruction (AEGAR) for branched endovascular treatment of complex iliac artery aneurysms. METHODS In 7 consecutive patients with CIA or IIA aneurysms, computed tomography angiography (CTA) and center-line reconstruction revealed aortoiliac anatomy incompatible with the current IBE IFU due to inadequate proximal CIA landing zone (n = 7), inadequate renal artery to iliac bifurcation length (n = 2), compromised aortic anatomy (n = 3), or short infrarenal neck <15 mm (n = 1), either alone or in combination. To overcome these restrictions and facilitate IBE deployment, aortoiliac reconstruction was performed using the Endologix AFX, Endologix Ovation limbs or the Medtronic Endurant II platforms (AEGAR technique). All internal iliac artery reconstructions and external iliac artery extensions were performed using the Gore VBX or Viabahn stent grafts. Technical success was defined as successful delivery of all endograft components without migration or endoleak. RESULTS The mean patient age was 69 years (range 52-82 years; 6 male). Four patients had bilateral CIA aneurysms and 3 patients had unilateral CIA aneurysms (mean diameter 4.3cm; range 2.2-7 cm). There were 13 IIA VBX stent grafts used for a total of 9 IIAs treated with IBE (bilateral IBE = 2 patients). The mean fluoroscopy time was 38.8 min (range 21.3-64.3 min) and the mean contrast volume was 168.5 mL (range 122-226 mL). Technical success was achieved in all patients and there were no perioperative complications. Mean hospital-stay was 2.2 days (range 1-3 days). Follow-up ranged from 82-957 days (mean = 487 days). At last follow-up, all patients were alive without cardiovascular morbidity; and CTA revealed stable or decreased aneurysm size, patent endografts, and no evidence of endoleak or migration. CONCLUSIONS The AEGAR technique can be used to safely and effectively overcome certain aortoiliac anatomic constraints that preclude use of current IBE technology. We encourage broader use of these alternative endografts in pertinent anatomic configurations.

Outcomes of Hypogastric Coverage and Occlusion during Endovascular Treatment of Aortoiliac Occlusive Disease. Ann Vasc Surg 2021; 77:116-126. [PMID: 34411668 DOI: 10.1016/j.avsg.2021.05.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 04/01/2021] [Accepted: 05/06/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND The risk of hypogastric occlusion (HO) following bare-metal stent (BMS) coverage of the hypogastric origin during endovascular treatment of aortoiliac occlusive disease (AIOD) is unclear. This study sought to determine the rate and clinical significance of HO following BMS coverage during iliac stenting for complex AIOD. METHODS Consecutive patients undergoing elective iliac stenting for AIOD from 2010-2018 at Cleveland Clinic were reviewed. Patients with BMS coverage of a patent hypogastric origin were included. Rate of HO were determined by review of intraoperative angiography and follow up imaging. Predictors of HO were identified by univariable and multivariable logistic regression. Outcomes were compared between those who did and did not develop HO. RESULTS There were 251 patients (338 limbs) with BMS coverage of the hypogastric origin during treatment of AIOD. Lesion severity was classified as TASC C/D in 249/338 (73.7%) of cases. Bilateral hypogastric coverage occurred in 93/251 (37.1%) patients. Hypogastric patency was 78.1% at 24-months following coverage. Recanalization of an ipsilateral external iliac artery (EIA) occlusion was predictive of HO (HR 3.12, 95% CI: 1.33, 7.34; P= 0.009). Increased luminal diameter of the hypogastric origin protected against HO (HR 0.64; 95% CI: 0.47, 0.88; P= 0.006). Perioperative outcomes were no different between patients with and without HO. There were no cases of gluteal necrosis, spinal cord ischemia, or pelvic organ ischemia. Four-year mortality and limb salvage were not affected by HO. HO was associated with decreased primary patency of ipsilateral iliac stents and increased risk of ipsilateral reintervention (HR 5.49; 95% CI: 1.82, 16.58; P= 0.002). CONCLUSIONS HO is relatively infrequent following BMS coverage during treatment of AIOD. Luminal diameter of the hypogastric origin and ipsilateral EIA occlusion are associated with occlusion. HO is well tolerated in AIOD, though it is potentially associated with increased risk iliac stent occlusion and reintervention.

Bilateral Use of Iliac Branch Devices for Aortoiliac Aneurysms Is Safe and Feasible, and Procedural Volume Does Not Seem to Affect Technical or Clinical Effectiveness: Early and Midterm Results From the pELVIS International Multicentric Registry. J Endovasc Ther 2021; 28:585-592.

Abstract
OBJECTIVE To evaluate early and follow-up outcomes following bilateral use of iliac branch devices (IBD) for aortoiliac endografting and assess the impact of center volume. We used data from the pELVIS international multicentric registry. METHODS For the purpose of this study, only those patients receiving concomitant bilateral IBD implantation were analyzed. To assess the impact that procedural volume of bilateral IBD implantation could have on early and follow-up outcomes, participating institutions were classified as Site(s) A if they had performed >10 and/or >20% concomitant bilateral IBD procedure, otherwise they were classified as Site(s) B. Endpoints of the analysis included early (ie, 30-day) mortality and morbidity, as well as all-cause and aneurysm-related mortality during follow-up. Additional endpoints that were evaluated included IBD-related reinterventions, IBD occlusion or stenosis requiring reintervention (ie, loss of primary patency), and IBD-related type I endoleak. RESULTS Overall, 96 patients received bilateral IBD implantation (out of 910 procedures collected in the whole pELVIS cohort), of whom 65 were treated at Site A (ie, Group A) and 31 were treated at Site(s) B (ie, Group B). In total, only 1 death occurred within 30 days from bilateral IBD implantation, and 9 patients experienced at least 1 major complication without any significant difference between subjects in Group A versus those in Group B (10.8% vs 6.5%, p=0.714). In the overall cohort, the 2-year freedom from IBD-related type I endoleaks and IBD primary patency were 96% and 92%, respectively; no significant differences were seen in those rates between Group A or Group B (95% vs 100%, p=0.335; 93% vs 88%, p=0.470). Freedom from any IBD-related reinterventions was 83% at 2 years, with similar rates between study groups (85% vs 83%, p=0.904). CONCLUSIONS Within the pELVIS registry, concomitant bilateral IBD implantation is a safe and feasible technique for management of aortoiliac aneurysms in patients with suitable anatomy. Despite increased technical complexity, effectiveness of the repair is satisfactory with low rates of IBD-related adverse events at mid-term follow-up. Procedural volume does not seem to affect technical or clinical outcomes after bilateral use of IBD, which remains a favorable treatment option in selected patients.

Abstract
OBJECTIVES Although commercial iliac branch devices offer a new and valid endovascular approach to treating iliac aneurysm and effectively preserve antegrade flow of the internal iliac artery, their use may not be suited for all types of challenging anatomy, especially isolated common iliac artery aneurysm. Our custom-made iliac bifurcation device has a unique design and excludes both combined and isolated iliac branch aneurysm. This study validated the efficacy and safety of the custom device by comparing clinical outcomes between groups receiving commercial and custom devices. METHODS Data of consecutive patients receiving iliac bifurcation device implantation for iliac aneurysm with or without concomitant endovascular repair for abdominal aortic aneurysm from January 2010 to May 2019 were reviewed. RESULTS Iliac bifurcation device implantation with or without concomitant abdominal aortic aneurysm stent grafting was completed in 46 patients (commercial, n = 35; custom, n = 11). No significant differences were observed regarding postoperative complications, occlusion or endoleak. Comparisons of primary (80.8% vs 85.7%, P = 0.88) and secondary (86.5% vs 85.7%, P = 0.85) patency and freedom from reintervention (88.2% vs 100%, P = 0.33), all-cause mortality (78.6% vs 100%, P = 0.25) and aneurysm-related mortality (100% vs 100%, P = 1.00) also indicated no differences at a 5-year surveillance point. Furthermore, the iliac aneurysms of the groups displayed similar shrinkage 1 year after procedures. CONCLUSIONS For iliac aneurysm, the novel custom-made iliac bifurcation device is an adaptable design not inferior to commercial devices with regard to postoperative complications, bridge occlusion, endoleak and short-term aneurysm remodelling. It provides an alternative for treatment, particularly when certain anatomic challenges are present. CLINICAL TRIAL REGISTRATION 2018-07-050BC, 2017-01-023ACF.

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
OBJECTIVES The Amplatzer Vascular Plug (AVP) is a vascular occlusion device designed to provide optimal embolization in several fields of the endovascular surgery. A full literature review was conducted to analyze AVPs in comparison with coils for the prevention of endoleaks during endovascular abdominal aortic aneurysm repair. METHODS A systematic review was designed under PRISMA statement guidelines for systematic reviews and meta-analyses. The results were updated with a subsequent electronic search using Medline and Scopus databases up to December 2019. RESULTS Eighteen articles making this comparison were found. In 79.7% of the cases, the target vessel was the internal iliac artery; in 1.6%, the common iliac artery; and in 16.7%, the inferior mesenteric artery. Risk of complications (buttock claudication, groin hematoma, endoleaks, and erectile dysfunction) after AVP was low. A cost comparison revealed that the mean cost for coils was around US$2262, while the average cost for the AVP was US$310. CONCLUSIONS The AVP is an effective and safe device for occluding peripheral vessels, proved to have lower complications rates. Compared with coil embolization, the AVP technique is potentially associated with lower procedural costs.

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 The aim of this study was to present a multicentre experience of technical results and mid-term follow-up using a custom-made iliac fenestrated device (Terumo Aortic, Inchinnan, Renfrewshire, UK) for the treatment of iliac aneurysms and endoleaks. METHODS A multicentre retrospective evaluation of 22 patients (3-12 per institution) with either an iliac artery aneurysm or endoleak treated with an iliac fenestrated device was performed. Data were gathered from 3 departments of vascular and endovascular surgery at 3 European institutions. RESULTS Ten of the included patients (45.5%) were treated for an endoleak and 12 had aorto-iliac aneurysms (54.5%). Two patients underwent bilateral fenestrated device implantation for a total of 24 devices included in this analysis. Primary technical success was 91.7% (22 of 24 implanted devices). One of the 24 internal iliac arteries could not be cannulated and was covered (primary assisted technical success rate 95.8%) and 1 patient required a relining of the stent graft due to a mid-grade stenosis opposite the internal iliac artery fenestration. Survival at the last available follow-up (mean 15.2 ± 12.0 months, range 0.5-36.6 months) was 90.9%. CONCLUSIONS The present investigation adds to a growing body of literature on custom-made endografts and their usefulness in achieving endovascular repair without compromising blood flow via important arterial branch vessels, such as the internal iliac artery. It presents encouraging technical and mid-term follow-up data from consecutive patients treated for iliac aneurysms or endoleaks using this custom-made device. The technique may help avoid adverse sequelae associated to a coil-and-cover approach when iliac branch devices are not feasible.

Abstract
BACKGROUND When an internal iliac artery (IIA) has to be embolized during endovascular aneurysm repair (EVAR), buttock claudication sometimes poses problems. However, there is no established method to evaluate intraoperative blood flow to the gluteal muscles.Methods and Results:Gluteal regional oxygen saturation (rSO2) was monitored using near-infrared spectroscopy (NIRS) during surgery, and changes in rSO2were compared with treatment results. Twenty-seven patients who underwent EVAR and IIA embolization at our institution between April 2019 and May 2020 were included in this study. The association between intraoperative changes in rSO2and postoperative incidence of buttock claudication was analyzed. Furthermore, the presence or absence of communication between the superior and inferior gluteal arteries and the intraoperative changes in rSO2were compared to ascertain whether rSO2reflects blood flow change. Postoperative buttock claudication occurred in 4 of 19 patients (21%) with unilateral occlusion of IIA and in 4 of 8 patients (50%) with bilateral occlusion of IIAs. rSO2was found to decrease significantly further in patients with buttock claudication than in patients without buttock claudication (-15±12% vs. -4±16%, P<0.05). In addition, rSO2was predominantly lower in patients without the communication between the superior and inferior gluteal arteries than in those with the communication. CONCLUSIONS Gluteal rSO2is useful as an indicator of intraoperative gluteal blood flow.
