[PMID: 37940086 DOI: 10.1016/j.avsg.2023.09.100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/29/2023] [Accepted: 09/29/2023] [Indexed: 11/10/2023]
Abstract
BACKGROUND Type II endoleak is the most common complication of endovascular aneurysm repair. Retrograde perfusion from the aneurysmal sac side branch to the aneurysmal sac, including the inferior mesenteric artery and lumbar arteries, is associated with adverse events after endovascular aneurysm repair, such as aneurysm sac enlargement, reintervention, rupture, and abdominal aortic aneurysm-related death. Preemptive embolization of the aneurysmal sac side branch before endovascular aneurysm repair is an effective and safe procedure for preventing type II endoleak and reducing the size of the aneurysmal sac. Since 2019, we have been conducting preemptive embolization of the inferior mesenteric artery and lumbar arteries. Thus, we intended to work on a two-stage endovascular aneurysm repair in which embolization and endovascular aneurysm repair are performed on separate days, owing to concerns about prolonged operative time and increased contrast media use and radiation exposure from performing endovascular aneurysm repair simultaneously. This study aimed to evaluate the effects of a two-stage endovascular aneurysm repair. METHODS This retrospective study included 114 cases of endovascular aneurysm repair (95 men and 19 women) for AAA performed at our hospital between January 2019 and December 2022. Inferior mesenteric artery and lumbar artery embolization were performed simultaneously with endovascular aneurysm repair (simultaneous group) in 49 cases, and two-stage embolization was performed (two-stage group) in 30 cases. The primary endpoints included the occurrence of T2EL during follow-up and the embolization rate of the IMA or LAs. RESULTS Type II endoleak did not occur in the two-stage group (follow-up period: 35 ± 6.2 months), whereas it was observed in 8.2% of patients more than 6 months after EVAR in the simultaneous group (follow-up period: 28 ± 5.5 months). While the total operative time was 340 ± 111.2 min in the simultaneous group, the durations for embolization and endovascular aneurysm repair in the two-stage group were 169 ± 35.5 min and 135.0 ± 26.4 min (total time 304 ± 31.2 min, P = 0.21), respectively, indicating a reduction in the total time required for the 2 techniques. The total amounts of contrast media used in the simultaneous and two-stage groups were 200.0 ± 179.2 mL and 182.0 ± 51.2 mL (P = 0.42), respectively, and the corresponding total radiation doses were 2502.4 ± 690.5 mGy and 2114.6 ± 351.2 mGy (P = 0.28), respectively, showing a decrease in both in the two-stage group. The lumbar artery embolization rates were 74.3% and 87.9% (P < 0.01) in the simultaneous and two-stage groups, respectively, indicating a significant difference. CONCLUSIONS Two-stage endovascular aneurysm repair with preemptive embolization of the inferior mesenteric artery and lumbar arteries may be an effective strategy for reducing type II endoleak occurrence, overall operative time, contrast use, and overall radiation exposure.

Abstract
PURPOSE Outcomes of late open conversion with graft replacement for enlargement after endovascular aortic repair remain unclear. Here, we report the outcomes of graft replacement after endovascular aortic repair. MATERIALS AND METHODS Fourteen patients who underwent graft replacement after endovascular aneurysm repair between November 2016 and October 2022 were included. Graft replacement was indicated in cases of rupture and enlargement of the aneurysm sac and when reintervention with endovascular therapy could not be performed. RESULTS The mean age at graft replacement was 80 ± 7 years. The follow-up period from endovascular aortic repair to graft replacement was 73 ± 41 months. The endoleaks that caused enlargement of the aneurysm sac were type I in 8 patients and type II in 6 patients. Ruptures were observed in 5 patients. One patient had paraplegia as a postoperative complication, and 2 patients died within 30 days. Morbidity and mortality were observed in cases of rupture, and no morbidity or mortality was observed in any elective surgery cases. CONCLUSION Late open conversion with graft replacement after endovascular aortic repair is a feasible elective surgery. However, morbidity and mortality have been observed in cases of rupture. CLINICAL IMPACT In elective surgery, postoperative outcomes are good for late open conversion with graft replacement after endovascular aortic repair. On the other hand, morbidity and mortality were observed in case of rupture. Therefore, it is important to perform elective surgical reintervention at the appropriate time.

Abstract
An enlarging internal iliac artery aneurysm secondary to a type II endoleak after endovascular aortic repair is an uncommon entity. It carries a significant rupture risk and mortality if not addressed. The present patient had had a 6.8-cm, rapidly growing, excluded hypogastric aneurysm. The results included both a failed transarterial approach and successful percutaneous transgluteal internal iliac artery aneurysm embolization using XperCT software (Philips Healthcare, Andover, MA) for guidance. The salient points included that treatment of the "nidus" alone will not be sufficient for complete endoleak embolization, the use of direct endoleak sac angiography might better delineate the inflow and outflow dynamics than conventional transarterial angiography, and XperCT guidance (Philips Healthcare) can facilitate complex endoleak access.

Patent iliolumbar artery increase no risk of type II endoleaks after endovascular abdominal aortic aneurysm: a case-control study. Front Cardiovasc Med 2023; 10:1210248. [PMID: 37636305 PMCID: PMC10455956 DOI: 10.3389/fcvm.2023.1210248] [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: 04/22/2023] [Accepted: 07/31/2023] [Indexed: 08/29/2023] Open
Abstract
Objective The aims of the present study were to explore the risk factors for type 2 endoleaks (T2ELs) after endovascular aneurysm repair (EVAR) and the association between T2ELs and the iliolumbar artery. Materials and methods A single-center, retrospective case-control study in West China Hospital was conducted among patients with infrarenal abdominal aortic aneurysm (AAA) who underwent EVAR between June 2010 and June 2019. The associations of patient characteristics, anatomical factors, internal iliac artery embolization, and ILA with the primary outcome were analyzed. The secondary objective was to analyze survival and reintervention between the T2EL group and the non-T2EL group. Kaplan-Meier survival, propensity matching analysis and multivariate logistic regression analysis were used. Results A total of 603 patients were included. The median follow-up was 51 months (range 5.0-106.0). There was a significant difference in the diameter of the lumbar artery (LA), middle sacral artery (MSA) and inferior mesentery artery (IMA), proportion of thrombus and LA numbers. The univariate analysis showed that T2ELs were more likely to develop more thrombus in aneurysm cavity (OR = 0.294, p = 0.012), larger MSA (OR = 1.284, p = 0.04), LA (OR = 1.520, p = 0.015), IMA (OR = 1.056, p < 0.001) and more LAs (OR = 1.390, p = 0.019). The multivariate analysis showed that the number of LAs (HR: 1.349, 95% CI: 1.140-1.595, p < .001) and the diameter of the IMA (HR: 1.328, 95% CI: 1.078-1.636, p = 0.008) were significantly associated with T2ELs. There were no new findings from the propensity score matching. The reintervention-free survival rates were significantly different between the two groups (p = 0.048). Overall survival and AAA-related death rates were not different between the two group. This was consistent with the PSM analysis. Conclusion The iliolumbar artery and the different internal iliac artery interventions may not increase the incidence of T2ELs. But the numbers of LAs and IMA diameter were independent risk factors for T2Els. T2ELs was associated with the reintervention but did not affect long-term survival or increase aneurysm-related mortality after EVAR.

Abstract
INTRODUCTION Endovascular aneurysm repair has improved outcomes for ruptured abdominal aortic aneurysms (rAAA) compared with open repair. We examined the impact of aorto-uni-iliac (AUI) vs standard bifurcated endograft configuration on outcomes in rAAA. METHODS Patients 18 years or older in the Vascular Quality Initiative database who underwent endovascular aneurysm repair for rAAA from January 2011 to April 2020 were included. Patient characteristics were analyzed by graft configuration: AUI or standard bifurcated. Primary and secondary outcomes included 30-day mortality, postoperative major adverse events (myocardial infarction, stroke, heart failure, mesenteric ischemia, lower extremity embolization, dialysis requirement, reoperation, pneumonia, or reintubation), and 1-year mortality. A subset propensity-score matched cohort was also analyzed. RESULTS We included 2717 patients: 151 had AUI and 2566 had standard bifurcated repair. There was no significant difference between the groups in terms of age, major medical comorbidities, anatomic aortic neck characteristics, or rates of conversion to open repair. Patients who underwent AUI were more commonly female (30% vs 22%, P = .011) and had a history of congestive heart failure (19% vs 12%, P = .013). Perioperatively, patients who underwent AUI had a significantly higher incidence of cardiac arrest (15% vs 7%, P < .001), greater intraoperative blood loss (1.3 L vs 0.6 L, P < .001), longer operative duration (218 minutes vs 138 minutes, P < .0001), higher incidence of major adverse events (46.3% vs 33.3%, P = .001), and prolonged intensive care unit (7 vs 4.7 days, P = .0006) and overall hospital length of stay (11.4 vs 8.1 days, P = .0003). Kaplan-Meier survival analyses demonstrated significant differences in 30-day (31.1% vs 20.2%, log-rank P = .001) and 1-year mortality (41.7% vs 27.7%, log-rank P = .001). The propensity-score matched cohort demonstrated similar results. CONCLUSIONS The AUI configuration for rAAA appears to be implemented in a sicker cohort of patients and is associated with worse perioperative and 1-year outcomes compared with a bifurcated graft configuration, which was also seen on propensity-matched analysis. Standard bifurcated graft configuration may be the preferred approach in the management of rAAA unless AUI configuration is mandated by patient anatomy or other extenuating circumstances.

Evolution of open aneurysmorrhaphy for management of sac expansion after endovascular repair of abdominal aortic aneurysms. J Vasc Surg 2023; 77:760-768. [PMID: 36306936 DOI: 10.1016/j.jvs.2022.10.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 10/12/2022] [Accepted: 10/13/2022] [Indexed: 11/05/2022]
Abstract
OBJECTIVE We evaluated the perioperative and mid-term clinical outcomes of open aneurysmorrhaphy (OA) for the treatment of sac expansion after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms. METHODS OA involves sac exposure without dissection of the proximal or distal neck, sacotomy and ligation of back-bleeding vessels, preservation of the prior stent graft, and tight closure of the sac around the stent graft. We performed a retrospective review of all patients who had undergone OA for nonruptured sac expansion after standard EVAR at our institution between January 2015 and June 2021. The primary end points were 30-day mortality and aneurysm-related death. The secondary end points were postoperative complications, overall survival, freedom from reintervention, and sac regrowth rate. RESULTS A total of 28 patients had undergone OA. Their mean age was 76.9 ± 6.7 years. The median sac diameter at OA was 79 mm (interquartile range [IQR], 76-92 mm). The median duration from the index EVAR to OA was 82 months (IQR, 72-104 months). Preoperative computed tomography angiography confirmed a type II endoleak (EL) in 20 patients, 1 of whom had had a coexisting type Ia EL; a type IIIb EL was identified in 1 patient. Concomitant endovascular procedures had been performed in six patients to treat a type I or III EL or reinforce the proximal and distal seals. The OA technique has been modified since 2017, with the addition of more aggressive dissection of the sac and complete removal of the mural thrombus to further decrease the sac diameter. Postoperative complications occurred in two patients and included abdominal lymphorrhea and failed hemostasis of the common femoral artery requiring surgical repair in one patient each. The 30-day mortality was 0%. During the median follow-up of 36 months (IQR, 14-51 months), the overall survival was 92.7% and 86.9% at 12 and 36 months, respectively, without any aneurysm-related death. In the late (2017-2021) treatment group, the median sac diameter immediately after OA was smaller than that in the early (2015-2016) treatment group (early group: median, 50 mm; IQR, 39-57 mm; vs later group: median, 41 mm; IQR, 32-47 mm; P = .083). Furthermore, in the late group, the sac regrowth rate was lower (early group: median, 0.36 mm/mo; IQR, 0.23-0.83 mm/mo; vs late group: median, 0 mm/mo; IQR, 0-0.11 mm/mo; P = .0075) and the freedom from reintervention rate was higher (late group: 94.7% at both 12 and 36 months, respectively; early group: 71.4% and 53.6% at 12 and 36 months, respectively; log-rank P = .070). CONCLUSIONS Our results have shown that OA for the management of post-EVAR sac expansion is feasible with acceptable mid-term outcomes. Aggressive dissection and tight plication of the sac might be imperative for better mid-term outcomes after OA.

Abstract
PURPOSE Type III endoleak can be difficult to distinguish from Type I endoleak. Depending on the stent graft anatomy, the use of standard bifurcated endografts may not be technically feasible, and patients may have to be subject to an aorto-uni-iliac repair with femoral-femoral bypass or open surgery. CASE REPORT We report a case of an 86-year-old male who had a Type IIIb endoleak 20 years post EVAR which was characterized on angiography to be from a hole close to the bifurcation limb origin. The initial Talent (Medtronic, Santa Rosa, California) device had a 50 mm main body common trunk, which was not amenable to treatment with standard devices. He was successfully treated with a custom-made device with an inverted contralateral limb. CONCLUSIONS Our case highlights the need for lifelong surveillance post EVAR as endoleak may present decades post initial EVAR. It also demonstrates that many Type III endoleak which were otherwise deemed unsuitable for treatment with standard devices may potentially be treatable with custom-made device (CMD). This solution preserves a percutaneous option in a now older person which avoids surgical bypass. Further studies are required to establish the durability of this treatment and survey for recurrence.

Abstract
OBJECTIVE Type II endoleaks (T2E), commonly identified after endovascular aneurysm repair (EVAR), have been associated with late endograft failure and secondary rupture. Number and size of patent aortic aneurysm sac outflow vessels, namely the inferior mesenteric, lumbar, and accessory renal arteries, have been implicated as known risk factors for persistent T2E. Given technical challenges associated with post-EVAR embolization, prophylactic embolization of aortic aneurysm sac outflow vessels has been advocated to prevent T2E; however, current evidence is limited. We sought to examine the effect of concomitant prophylactic aortic aneurysm sac outflow vessels embolization in patients undergoing EVAR. METHODS Patients 18 and older in the SVS Vascular Quality Initiative database who underwent elective EVAR for intact aneurysms between January 2009 and November 2020 were included. Patients with history of prior aortic repair and those without available follow-up data were excluded. Patient demographics, operative characteristics, and outcomes were analyzed by group: EVAR with or without prophylactic sac outflow vessel embolization (emboEVAR). Outcomes of interest were rates of in-hospital postoperative complications, incidence of aneurysmal sac regression (≥5mm) and T2E, and rates of re-intervention in follow-up. RESULTS 15060 patients were included: 272 had emboEVAR and 14788 had EVAR alone. There was no significant difference between groups in terms of age, comorbidities, or anatomic characteristics including mean maximum preoperative aortic diameter (5.5 vs. 5.6 cm, p=0.48). emboEVAR was associated with significantly longer procedural times (148 vs. 124 minutes, p<0.0001), prolonged fluoroscopy (32 vs. 23 minutes, p<0.0001), increased contrast use (105 vs. 91 mL, p<0.0001), without significant reduction in T2E at case completion (17.7% vs. 16.3%, p=0.54). Incidence of postoperative complications (3.7% vs. 4.6%, p=0.56), index hospitalization reintervention rates (0.7% vs. 1.3%, p=0.59), length of stay (1.8 vs. 2 days, p=0.75), and thirty-day mortality (0% vs. 0%, p=1) were similar between groups. In mid-term follow-up (14.6±6.2 months), the emboEVAR group had a significantly greater mean reduction in maximum aortic diameter (0.69 vs. 0.54 cm, p=0.006) with a higher proportion experiencing sac regression ≥5 mm (53.5% vs. 48.7%). Re-intervention rates were similar between groups. On multivariable analysis, prophylactic aortic aneurysm sac outflow vessel embolization (OR 1.34, CI 1.04-1.74, p=0.024) was a significant independent predictor of sac regression. CONCLUSIONS Prophylactic sac outflow vessel embolization can be performed safely for patients with intact aortic aneurysms undergoing elective EVAR without significant associated perioperative morbidity or mortality. emboEVAR is associated with significant sac regression compared to EVAR alone in mid-term follow-up. Although there was not a decrease in the incidence of T2E, this technique shows promise and future efforts should focus on identifying a subset of aneurysm and outflow branch characteristics that will benefit from concomitant selective versus complete prophylactic sac outflow vessel embolization.
