RESUMO
BACKGROUND: Assess subsequent cardiovascular events and all-cause mortality in patients with intact abdominal aortic aneurysm (AAA) treated by endovascular aneurysm repair (EVAR) according to the existence of isolated endoleak type 2 (EL2) at 1 year after EVAR implantation. METHODS: This retrospective, single-center study included patients treated with EVAR between 2010 and 2017 in the vascular surgery department of the University Hospital of Lyon with an infrarenal AAA > 50 mm. The baseline clinical characteristics collected just before EVAR were retrieved from electronic patient records of our institution. AAA characteristics, procedure, and the 1-year postoperative computed tomography angiography (CTA) were reported. Study end points, major adverse cardiovascular events (MACE), major adverse lower-extremity events (MALE), and all-cause mortality were recorded during follow-up. Patients were divided into 2 groups according to the presence of isolated EL2 (EL2 +) or absence (EL2 -) of any endoleak on CTA at 1 year. MACE, MALE, and all-cause mortality were compared between both groups. RESULTS: During the study period, 589 patients were treated by endovascular surgery and 207 were included. According to the CTA results at 1 year, 60 patients (29%) were included in the EL2 + group and 147 patients (71%) in the EL2 - group. A total of 109 patients (53%) experienced a MACE or MALE; significantly fewer patients in the EL2 + than in the EL2 - group did so (P = 0.009). There were 47 patients (23%) who experienced at least 1 MALE, and the frequency was significantly lower in the EL2 + group (P = 0.017). CONCLUSIONS: Patients with AAA treated by EVAR who did not develop EL2 at 1 year were at higher risk of MALE during follow-up. This might be explained by more frequent symptomatic lower extremity peripheral arterial disease at baseline in this group. These patients therefore require a closer follow-up and strict control of cardiovascular risk factors to prevent cardiovascular morbi-mortality.
RESUMO
BACKGROUND: The purpose of this study was to assess whether the presence of an aneurysmal or dissecting arterial disease was a risk factor of poor prognosis in patients presenting a dissection of the celiac trunk (CT). METHODS: All patients presenting a CT dissection between January 1, 2014, and June 30, 2022, were included. Patients with a CT dissection due to the extension of an aortic dissection were excluded. Les antécédents familiaux de dissection, de maladie anévrysmale, de maladie athéromateuse ou du tissu conjonctif, la pratique d'une activité physique ou sportive, un effort inhabituel les jours précédant la dissection ainsi qu'un traumatisme étaient recherchés. Family history of dissection, aneurysmal disease, atheromatous or connective tissue disease, physical activity or sport, an unusual effort in the days prior to the dissection and trauma were sought after. Ischemic or aneurysmal complications in the acute phase and the evolution of the dissection were evaluated and compared between patients with an isolated dissection and those presenting an aneurysmal or dissecting arterial disease. RESULTS: 45 patients were included in the study. Twenty-three (51.1%) patients presented with symptomatic CT dissection, and 22 (48.9%) with asymptomatic CT dissection. All the patients initially had medical management alone. The mean follow-up was 32 ± 25 months and all patients were asymptomatic at the time last news. 24 (53.3%) presented an isolated CT dissection, and 21 (46.7%) a CT dissection associated with aneurysmal or dissecting arterial disease. There was no significant difference between patients with an isolated CT dissection and those with an associated dissecting or aneurysmal pathology. CONCLUSIONS: CT dissection is a stable disease in the midterm, which makes it a mild arterial pathology, with or without aneurysmal or dissecting anomalies in another territory. The mechanical stress exerted on the CT by the arcuate ligament could be responsible for parietal trauma and favor the occurrence of a CT dissection.

OBJECTIVES: To investigate whether the occurrence of ischemic stroke due to carotid stenosis is a marker of the severity of atherosclerotic disease and of an excess risk of cardiovascular morbidity and mortality, and of all-cause mortality, after carotid endarterectomy. METHODS: Patients who had undergone a carotid endarterectomy (CEA) from June 2015 to august 2016 were included. Patients were classified into two groups, namely symptomatic and asymptomatic. Neurological event, myocardial infarction and death during early follow-up were monitored. Major adverse cardiovascular events (MACE), major limb events (MALE), and all-cause mortality were compared for patients with a CEA for an asymptomatic carotid stenosis versus those with a symptomatic stenosis. RESULTS: Among the 190 patients included, 86 (51%) had a CEA for an asymptomatic stenosis and 84 (49%) for a symptomatic stenosis. During the first 30 days, the rate of all-cause death or ischemic stroke was similar in both groups (1%, p=0.986). After 30 days, there were a total of 35 MACE (21.3%) and 15 MALE (9.1%) during mean follow-up of 53 (22.6) months. Overall cardiovascular morbidity and mortality was 30.4%, and did not differ between groups (p=0.565). New ischemic stroke occurred in 11 patients (9.1%) and was significantly more frequent in the asymptomatic group (9 (14.8%) vs 2 (3.6%) in the symptomatic group, (OR: 4.96; CI 95% [1.04-23.77]; p = 0.013)). Overall all-cause mortality was 24% in both groups (p=0.93) CONCLUSION: The occurrence of ischemic stroke of carotid origin prior to revascularization does not appear to be associated with an excess risk of cardiovascular morbidity or mortality or all-cause mortality after surgery.
RESUMO
OBJECTIVES: The present study aimed to assess whether high-risk American Society of Anesthesiologists (ASA)-Physical Status was an independent risk factor for the development of surgical site infection (SSI) after infra-inguinal lower extremity bypass (LEB). SUMMARY OF BACKGROUND DATA: The ASA-Physical Status Classification System assesses the overall physical status preoperatively. ASA-Physical Status is associated with postoperative morbidity and mortality. However, limited data are available on how ASA-Physical Status Class affects the development of SSI after infra-inguinal LEB. METHODS: Patients who had undergone infra-inguinal LEB from January 1, 2015 to December 31, 2018, for obliterative arteriopathy or popliteal aneurysm at our university hospital were included. SSI risk factors were identified using multivariable logistic regression. The length of hospital stay, major limb events (MALE), major adverse cardiovascular events (MACE), and all-cause mortality were compared for patients with SSI versus those without SSI 3 months and 1- year of follow-up after the index surgery. RESULTS: Among the 267 patients included, 30 (11.2%) developed SSI during the 3-month period and 32 (12%) at 1 year. ASA-Physical Status ≥3 [odds ratio (OR): 3.7, 95% confidence interval CI) 1.5-11.1], emergency surgery (OR: 2.7, 95% CI 1.2-6.0), general anesthesia (OR: 2.8, 95% CI 1.3-6.1), and procedure performed by a junior surgeon (OR: 2.7, 95% CI 1.3-6.0) were independently associated with SSI. At 3 months and 1 year, SSI was significantly associated with MALE (including surgical wound debridement, subsequent thrombectomy, major amputation), length of hospital stay, and all-cause mortality. CONCLUSION: The ASA-Physical Status should be considered in medical management when an infra-inguinal LEB is considered in frail patients, to prevent surgical complications.

OBJECTIVE: The aim of this study was to compare midterm results of EndoAnchors in EndoSuture aneurysm repair (ESAR) versus fenestrated endovascular aneurysm repair (FEVAR) in short neck abdominal aortic aneurysm (AAA). METHODS: All patients who underwent an ESAR procedure for a short neck AAA at our center between September 2017 and May 2020 were considered for analysis. To form the control group, preoperative computed tomography angiography of patients who underwent FEVAR for juxtarenal AAA between April 2012 and May 2020 were reviewed and patients who met short neck criteria selected. A propensity-matched score on neck length and neck diameter was calculated, resulting in 18 matched pairs. AAA shrinkage, type Ia endoleaks (EL), AAA-related reinterventions, and AAA-related deaths were compared. RESULTS: The median AAA diameter was 54 mm (interquartile range [IQR], 52-61 mm) versus 58 mm (IQR, 53-63 mm) with a median neck length of 8 mm (IQR, 6-12 mm) vs 10 mm (IQR, 6-13 mm) in ESAR and FEVAR patients, respectively. Technical success was 100% in both groups. Procedural success was 94% in the ESAR group versus 100% in the FEVAR group. The median procedure duration was 138 mm (IQR, 113-182 mm) vs 240 mm (IQR, 199-293 mm) ( P < .001) and the median length of stay was 2 days (IQR, 2-3 days) vs 7 days (IQR, 6-7 days) (P < .001) in ESAR and FEVAR patients, respectively. No major hospital complications were observed in ESAR patients compared with two in FEVAR patients (11%) with one transient acute kidney injury and one transient paraplegia. The median follow-up was 23 months (IQR, 19-33 months) vs 36 months (IQR, 22-57 months) with 67% versus 61% AAA shrinkage in the ESAR and FEVAR groups, respectively (P = .73). No type Ia EL, proximal neck-related reinterventions, or AAA-related deaths were observed in either group. No AAA-related reintervention was observed in the ESAR group versus three reinterventions in the FEVAR group (P = .23). CONCLUSIONS: ESAR seems to be a safe technique with no major postoperative complications or reinterventions observed during follow-up. It seems to offer similar midterm results as FEVAR in terms of type Ia EL, aneurysm shrinkage, and aneurysm-related mortality. ESAR seems to be a good off-the-shelf alternative to FEVAR in case of technical constraints.

BACKGROUND: The aim was to analyze the anatomic feasibility of the percutaneous axillary access (PAXA) using cadaverous models and then to analyze the complications associated with PAXA during Fenestrated or Branched Endovascular Aneurysm Repair (F/BEVAR) procedures. METHODS: Cadaverous models were used to analyze axillary pedicle after a PAXA on an initial anatomical investigation. A subclavian approach was performed after puncture to assess the injuries caused by the needle. Then, in an observational study, patients who underwent F/BEVAR using a PAXA between July 2019 and July 2021 were included. PAXA-related events and complications were monitored. RESULTS: Eleven dissections were performed on cadavers. The axillary vein was injured twice (18.2%); the puncture site on the axillary artery was found on the arterial proximal part, behind the clavicle. Fifty-three patients underwent a F/BEVAR using a PAXA. The mean (SD) age of patients was 74.5 (9.7) years. Most indications for endovascular repair were para-renal aneurysms (66%). Two Proglide® closure devices served to close arterial access in all procedures. Adjunct balloon inflation was used in 19 (35.8%) patients. There were 5 (9.4%) PAXA-related events included preoperative blush in 2 (3.8%) patients, axillary artery dissection in 2 (3.8%), and 1 (1.9%) axillary artery stenosis. Five patients (9.4%) had a postoperative axillary hematoma without need for additional surgical procedure. No PAXA-related complication was found after discharge (mean [SD] 11.7 [7.4] months following surgery). CONCLUSIONS: Percutaneous axillary artery access was an efficient upper extremity access and associated with a low rate of PAXA-related events.

Drug addiction is a major social and medical concern. Infected groin pseudoaneurysm (IGP) is the result of direct arterial needlestick injury associated with contamination of the arterial wall or peri-arterial area by the injection equipment. Femoral artery (FA) ligation with extensive debridement is an alternative to direct revascularization in an area of sepsis. In case of femoral bifurcation free of infection or in case of isolated FA below the femoral artery of thigh involvement, a simple ligation of the FA is performed. Ligation of each femoral vessel is indicated in case of extension of the infection to the femoral bifurcation. Proximal ligation is performed on the proximal part of the FA. Distal ligation is performed on the proximal part of the deep artery of thigh and the FA below the origin of the deep artery of thigh. Ligation is effective and represents an appropriate method to control hemorrhage and sepsis syndrome in IGP.

OBJECTIVE: The benefit of preventive treatment for superior mesenteric artery (SMA) stenosis remains uncertain. The latest European Society for Vascular Surgery (ESVS) guidelines remain unclear given the lack of data in the literature. The aim of this study was to evaluate asymptomatic SMA stenosis prognosis according to the presence of associated coeliac artery (CA) and/or inferior mesenteric artery (IMA) stenosis. METHODS: This was a single academic centre retrospective study. The entire computed tomography (CT) database of a single tertiary hospital was reviewed from 2009 to 2016. Two groups were defined: patients with isolated > 70% SMA stenosis (group A) and patients with both SMA and CA and/or IMA > 70% stenosis (group B). Patient medical histories were reviewed to determine the occurrence of mesenteric disease (MD) defined as development of acute mesenteric ischaemia (AMI) or chronic mesenteric ischaemia (CMI). RESULTS: Seventy-seven patients were included. Median follow up was 39 months. There were 24 patients in group A and 53 patients in group B. In group B, eight (10.4%) patients developed MD with a median onset of 50 months. AMI occurred in five patients with a median of 33 months and CMI in three patients with a median of 88 months. Patients of group B developed more MD (0% vs. 15.1%; p = .052). The five year survival rate was 45% without significant difference between groups. CONCLUSION: Patients with SMA stenosis associated with CA and/or IMA seem to have a higher risk of developing mesenteric ischaemia than patients with isolated SMA stenosis. Considering the low life expectancy of these patients, cardiovascular risk factor assessment and optimisation of medical treatment is essential. Preventive endovascular revascularisation could be discussed for patients with non-isolated > 70% SMA stenosis, taking into account life expectancy.

BACKGROUND: Isolated dissection of the superior mesenteric artery (SMA) is increasingly diagnosed; the conservative treatment appears to be the best option when blood supply is maintained. However, some patients require a more invasive attitude, due to acute or chronic ischemic complication. Multidisciplinary care within a health-care network improves medical and surgical support. We present a case of chronic complication of isolated SMA dissection requiring a revascularization, followed by bowel resection. CASE PRESENTATION: A 49-year-old man presented abdominal pain secondary to necrotizing enterocolitis of unknown cause. An isolated small bowel resection with immediate restoration of continuity was first performed to remove the necrotic tissue. The patient developed post-ischemic exudative enteropathy and small intestinal bacterial overgrowth (SIBO). Re-examination of the first computed tomography (CT) scan revealed an isolated dissection of the SMA that had not been diagnosed. The patient was then successfully treated by superior mesenteric revascularization, and after recovering, he underwent small bowel resection for chronic ischemia. CONCLUSIONS: SMA revascularization has to be performed in case of SMA dissection complicated of bowel ischemia. Enteropathy is a rare complication of chronic mesenteric ischemia requiring digestive and vascular management in a dedicated health-care team.

BACKGROUND AND AIMS: To evaluate if features of occlusion analyzable on preoperative computed tomography scan could predict risks of technical failure or iliac rupture of endovascular treatment of TransAtlantic InterSociety Consensus C-D aortoiliac chronic total occlusion. METHODS AND RESULTS: All patients treated by endovascular techniques for a TransAtlantic InterSociety Consensus C-D aortoiliac chronic total occlusion between 2009 and 2016 were included (107 patients, 148 iliac arteries). We evaluated the location of the occlusion and the importance of the arterial calcifications. For this factor, patients were divided into 3 groups: the Black occlusion group with mild or no calcifications, the white occlusion group with moderate no protrusive calcifications, and the white protrusive occlusion group with heavy endoluminal calcifications. Technical failure occurred in 11 iliac arteries and peroperative iliac rupture in 6. The location in the external iliac artery is the most significate risk factor of technical failure in univariate (OR = 9.93; P = 0.0012) and multivariate analysis (OR = 15.26; P = 0.0006). The presence of heavy endoluminal calcifications is a further significate risk factor (OR = 13.88; P = 0.0365). Rupture rate was comparable between the 3 groups. CONCLUSIONS: Preoperative computed tomography scan can predict risk of technical failure but not of iliac rupture.

OBJECTIVE: Carotid endarterectomy and carotid artery stenting are both valid therapeutic options for the treatment of radiation-induced carotid stenosis (RICS). The second has the advantage of being less invasive, although it seems to result in more restenosis than the first. Meanwhile, progress in radiation therapy and head and neck surgery has significantly increased the survival of these patients. As a result, treatment of RICS should be considered from a long-term perspective. This works presents perioperative and follow-up outcomes of surgical treatment of RICS. METHODS: This single-center retrospective study included all patients who underwent carotid endarterectomy for RICS from January 1998 to June 2017. Clinical and duplex ultrasound examination-based follow-up was performed postoperatively, at 1 month, 6 months, 12 months, and yearly thereafter. Kaplan-Meier curves were used for survival plots based on a log-rank test. Any abnormal finding led to angio-computed tomography scan and specialized neurovascular examination. RESULTS: Between 1998 and 2017, 128 patients (162 lesions) were treated. The median interval between radiation therapy and surgery was 16 years. Forty-five patients (35%) were symptomatic. The eversion technique was performed in 79 cases (49%), and the patch was favored in 24 cases (15%), prosthetic bypass graft in 51 cases (31%), and a venous bypass graft in 8 cases (5%). Two postoperative deaths (1.5%) (one secondary to massive stroke) were noted. The primary end point of early postoperative cerebrovascular event was 2.5%. Two cervical hematomas (1.2%) required surgical revision and seven cases of permanent cranial nerve injury were recorded. The median follow-up was 29 months (range, 2-199 months). There were no additional strokes. The 3-year primary patency rate was 96% and the 3-year freedom from neurologic event was 98%. CONCLUSIONS: Open surgical treatment of RICS lesions is a safe and durable option. Our results suggest that the outcomes of such treatment are good and in particular that rates of cerebrovascular event and restenosis are low and that cranial nerve injury should not be a concern. As a result, we consider that open surgery for RICS lesions should be offered as a first-line treatment. However, comparative data are mandated to address this issue.

OBJECTIVE: Treatment of renal artery aneurysms (RAA) remains controversial. Endovascular treatment has increased for main trunk and for very distal aneurysms, whereas for lesions located at the bifurcation surgical treatment seems to be a valid option. The goal of this study was to describe the technique of direct reconstruction of RAA and to report on outcomes. METHODS: This study comprised single centre prospective collection of data with retrospective analysis (January 2015 to August 2018) of patients operated on for distal RAA using direct reconstruction. RESULTS: A total of 24 RAA in 21 patients (seven men and 14 women, mean age 59 ± 13 years) was included. History of hypertension was found in 15 patients and renal insufficiency was present in one. Mean pre-operative systolic and diastolic blood pressures were 134 ± 21 mmHg and 74 ± 10 mmHg, and mean pre-operative rates of creatinine and glomerular filtration rate were 67 ± 13 µmol/L and 93 ± 49 mL/min/1.73 m2, respectively. Indications for repair were a diameter >20 mm in seven cases (mean diameter = 25 ± 2 mm) or rapid growth in one case, symptomatic aneurysm in 12 cases (hypertension, haematuria, pain), and a concomitant lesion in four cases (splenic aneurysm, abdominal aortic aneurysm, occlusive visceral artery lesions). All lesions were distal, main artery bifurcation in 22 cases and hilar in two cases. The main aetiology was fibromuscular dysplasia (16 cases) followed by atherosclerosis (seven cases) and one case of Ehlers Danlos Syndrome. In situ reconstruction was possible for 22 RAA, while two cases required kidney autotransplantation. The mean renal ischaemia time was 18 ± 5 min. At two years, the patency rate was 100%, and mean systolic blood pressure decreased (134 mmHg-122 mmHg, p = .047). Renal function was stable from 93 ± 49 pre-operatively to 95 ± 35 mL/min/1.73 m2 in the post-operative course (p = .56). CONCLUSION: Direct reconstruction appears to be efficient for most RAA. This technique is complementary to ex vivo autotransplantation and endovascular treatment.

BACKGROUND: A distal approach in endovascular procedures for revascularization of lowers limbs can be considered in case of no re-entry in subintimal recanalization. The aim of this study is to evaluate the feasibility of a medial approach to the infrageniculate popliteal artery (IPA) using existing computed tomography (CT) scan simulation and punctures performed on cadavers. METHODS AND RESULTS: CT angiographies of lower extremities were used to simulate IPA puncture and puncture trajectory. Tissues damaged during the trajectory between the puncture site and the access-related injuries were analyzed. Anatomical punctures on cadaverous model were also performed. Corpses were placed in supine position, the hip in slight flexion (40°) and abduction (external rotation of 60°). A 16 G needle was used for the IPA puncture. Twelve CT angiography simulations were made. Of these 12 simulations, 9 revealed an isolated lesion of the popliteal vein and 2 isolated lesions of the tibial nerve. A lesion of the tibial nerve and the popliteal vein on the same simulation was once observed. Damage to the medial gastrocnemius muscle could not be avoided in each case. Ten punctures were performed on cadavers with technical success. There were 6 popliteal vein lesions, 3 tibial nerve lesions, and 1 case without lesion. In all cases, damage to the medial gastrocnemius muscle was seen. CONCLUSIONS: This medial approach was feasible and is accompanied by trauma of elements of the popliteal pedicle. Preoperative CT angiography could anticipate best site of puncture and potential access-related injury.

BACKGROUND: Arterial injury secondary to acute knee dislocation (KD) is a rare but devastative complication. The aim of this study is to evaluate functional sequelae and factors of poor prognosis. METHODS: A retrospective monocentric series of consecutive KD with acute ischemia by popliteal artery injury was analyzed between 2005 and 2017. The main outcome was the amputation rate. RESULTS: Sixteen dislocations were included. Nine (56%) were due to public road accidents, 5 (31%) were due to falls from height, and 2 (13%) were due to sports injuries. Dislocation had occurred in the posterior location in 8 (50%) cases. Regarding arterial injury, there were 7 (44%) ruptures, 7 (44%) dissections, and 2 (13%) isolated thromboses. Eleven (69%) KDs with vascular trauma were associated with signs of acute ischemia. Revascularization was achieved by anatomical venous bypass in 14 (88%), resection and direct anastomosis in one (6%), and isolated thrombectomy in one (6%). Median time to surgery (time between trauma and vascular repair) was 7 hours (3.25-60.92 hours). Primary revascularization was performed in 12 (75%) cases. In three cases (19%), orthopedic reduction and stabilization were performed first. In one case, (6%) three-step management with vascular shunt at first, then with knee stabilization, and finally vascular bypass was carried out. Stabilization was achieved by using an external fixator in 13 (82%) cases, by open reduction and internal fixation in one case (6%), by ligamentoplasty in one (6%), and by using a long leg cast in one (6%). Fasciotomy was required in 12 (75%) cases. Two patients had early vascular complications, and 2 had early systemic complications. Three secondary transfemoral amputations were performed. Median follow-up duration was 23 months. No secondary amputation was recorded. At the end of follow-up, functional outcomes were evaluated using the Oxford Knee Score (OKS). The median OKS was 30 versus the pretrauma median OKS of 47 (P < 0.00028). No risk factor associated with limb amputation has been highlighted. CONCLUSIONS: Analysis of these results provided indications for therapeutic management of this condition. This study shows poor functional outcomes because of severity of vascular lesion in patients with orthopedic trauma but with healthy arteries.

OBJECTIVE: A suitable ipsilateral great saphenous vein (GSV) autograft is widely considered the best material for arterial reconstruction of a popliteal artery aneurysm (PAA). There are, however, cases in which such a GSV is absent, diseased, or of too small diameter for this use. Alternatives to GSV are synthetic conduits, but with a reduced long-term patency, in particular for infragenicular bypass; other venous autografts of marginal use; and stent grafts still in the first stages of their evaluation. However, a sufficiently long segment of the ipsilateral superficial femoral artery (SFA) is often preserved in patients with a PAA. Such a segment may be used as an autograft for popliteal reconstruction. Moreover, the morphometric characteristics of the SFA often optimally match those of the distal native popliteal bifurcation. SFA autografts (SFAAs) have therefore become our choice when the ipsilateral GSV is not suitable. We herein present the long-term results of SFAA for the treatment of PAA in the absence of a suitable GSV. METHODS: Within this single-center study, all cases during the last 26 years were retrospectively reviewed. Demographics, risk factors, comorbidities, morphometrics of the PAA, and preoperative and follow-up data were intentionally sought. RESULTS: From 1997 to 2017, there were 67 PAAs treated with an SFAA. The mean age of the patients was 67.67 ± 12 years, and 98% were male. Symptoms included intermittent claudication in 25% (17), critical limb ischemia in 7% (5), and acute ischemia in 10% (7) of the patients; 51% (34) of the patients were asymptomatic. The mean aneurysm diameter of the treated PAA was 29 ± 11 mm (12-61 mm). The mean operative time was 254.8 ± 65.6 minutes (140-480 minutes), with a mean cross-clamp time of 64.5 ± 39 minutes (19-240 minutes). The median length of stay was 9 ± 6.4 days (5-42 days). There were no early amputations or deaths in the series. During a mean follow-up of 47.91 ± 48.23 months, there were 2 anastomotic stenoses, 11 thromboses, 1 infection, and 1 aneurysmal degeneration of the graft; 6 patients died of unrelated causes. The 1-, 3-, 5-, and 10-year primary and secondary patency rates were 93% and 96%, 85% and 90%, 78% and 87%, and 56% and 87%, respectively. CONCLUSIONS: These data suggest that SFAA use to treat PAA is a safe and durable option. A prospective and comparative work is necessary to confirm these results and to determine the interest of this technique as a first-line strategy.

OBJECTIVE: The objective of this study was to assess outcomes of a hybrid technique for treatment of abdominal aortic aneurysm (AAA) associated with iliac aneurysm without distal neck by combining an AAA endovascular repair approach with open surgery for preservation of the internal iliac artery (IIA). METHODS: The files of 51 patients operated on between 1998 and 2017 in a single vascular surgery department were retrospectively analyzed. Inclusion criteria were patients with AAA associated with uni-iliac or bi-iliac aneurysm without suitable distal sealing zone. Surgery consisted of deployment of an aortouni-iliac stent graft combined with an extra-anatomic crossover prosthetic bypass. With use of a limited retroperitoneal approach, the contralateral proximal common iliac aneurysm was surgically excluded and the IIA revascularized by direct ilioiliac anastomosis or terminal common iliac suture, preserving the iliac bifurcation. RESULTS: The patients' mean age was 74 years (58-88 years), and 92% were men. The mean follow-up was 5.8 years (0.1-18 years). Twenty-nine patients (57%) had one or more high-risk criteria for open surgery. Nineteen patients (37.3%) had aortouni-iliac aneurysms, 19 (37.3%) aortobi-iliac aneurysms, 5 (10%) isolated iliac aneurysms, and 8 (15.7%) bi-iliac aneurysms without aortic location. Four patients (7.8%) also had IIA aneurysms. Surgery was successful in all cases. Two patients (4%) died during the 30 days after surgery. One surgically preserved IIA occluded within the first month, resulting in buttock claudication. The 5-year IIA primary patency rate was 96%. Type I proximal endoleaks occurred in two patients, requiring additional surgery 3 years and 13 years after the initial surgery, respectively. CONCLUSIONS: This hybrid technique, consisting of AAA endovascular exclusion combined with open IIA revascularization, is safe and effective for preservation of pelvic vascularization. It is associated with long-term patency and low morbidity rates. We have been using this technique since before the advent of branched dedicated devices, allowing preservation of the IIA with good results. This technique should continue to be proposed, especially in patients not eligible for endovascular iliac branch repair because of anatomic contraindications, to avoid pelvic ischemia if the IIA has to be sacrificed.
