Assessment of fenestrated Anaconda stent graft design by numerical simulation: Results of a European prospective multicenter study.

Objective: A crucial step in designing fenestrated stent grafts for treatment of complex aortic abdominal aneurysms is the accurate positioning of the fenestrations. The deployment of a fenestrated stent graft prototype in a patient-specific rigid aortic model can be used for design verification in vitro, but is time and human resources consuming. Numerical simulation (NS) of fenestrated stent graft deployment using the finite element analysis has recently been developed; the aim of this study was to compare the accuracy of fenestration positioning by NS and in vitro.

MRI associated factors of clinical efficacy of embolization in patients with pelvic venous insufficiency.

Purpose: The purpose of this study was to identify anatomical findings at magnetic resonance imaging (MRI) associated with successful percutaneous embolization in women with pelvic venous insufficiency (PVI).

Material And Methods: Between 2008 and 2018, 168 consecutive women (mean age, 39±9 [SD] years; range: 21-69 years) who underwent percutaneous embolization for PVI confirmed by MRI and phlebography were included. Clinical efficacy of embolization was evaluated by patients' opinion or visual analogue scale.

Computed Tomography-Aortography Versus Color-Duplex Ultrasound for Surveillance of Endovascular Abdominal Aortic Aneurysm Repair: A Prospective Multicenter Diagnostic-Accuracy Study (the ESSEA Trial).

Background Color-duplex ultrasonography (DUS) could be an alternative to computed tomography-aortography (CTA) in the lifelong surveillance of patients after endovascular aneurysm repair (EVAR), but there is currently no level 1 evidence. The aim of this study was to assess the diagnostic accuracy of DUS as an alternative to CTA for the follow-up of post-EVAR patients. Methods Between December 16, 2010, and June 12, 2015, we conducted a prospective, blinded, diagnostic-accuracy study, in 15 French university hospitals where EVAR was commonly performed.

Five Year Results of the French EPI-ANA-01 Registry of Anaconda Endografts in the Treatment of Infrarenal Abdominal Aortic Aneurysms.

Objective: A significant decrease in aneurysm related survival is observed at long term follow up after infrarenal endovascular aneurysm repair (EVAR) compared with open repair. Therefore, longer term results with new generation endografts are essential. The aim of this post-approval French multicentre prospective observational study (EPI-ANA-01) was to evaluate the technical success and five year mortality and secondary intervention rates of the third generation Anaconda endograft.

Endovascular Treatment of Complex Aneurysms with the Use of Covera Stent Grafts.

Purpose: To characterize the short-term results of a newly available self-expanding covered stent (Covera; CR Bard Peripheral Vascular Inc., Murray Hill, New Jersey) for the reconstruction of target vessels in complex aneurysms.

Materials And Methods: From August 2017 to November 2018, this self-expanding covered stent was used in 17 patients (mean 72.

Systematic review and updated meta-analysis of the use of drug-coated balloon angioplasty versus plain old balloon angioplasty for femoropopliteal arterial disease.

Objective: An endovascular-first approach is usually recommended in femoropopliteal occlusive disease. However, despite high technical success, plain old balloon angioplasty (POBA) is burdened with high restenosis rates. To reduce this phenomenon, local delivery of drugs has been proposed by way of drug-coated balloons (DCBs).

Midterm Results with the Open Chimney Technique during Endovascular Aneurysm Repair.

Purpose: To report the midterm experience with chimney-endovascular aneurysm repair (Ch-EVAR) with the use of open self-expending stents for branch vessel preservation.

Materials And Methods: From July 2010 to May 2017, 67 patients underwent open Ch-EVAR because their proximal landing zones were adjacent to, or covered, the renal or mesenteric arteries (Zones 7-9), and they were not suitable for standard or fenestrated endovascular aneurysm repair. The proximal landing zone was relocated below the highest renal artery in 46 cases, the superior mesenteric artery in 17 cases, and the celiac artery in 4 cases, using 84 open chimneys (131 stents).

Laparoscopic Resection of a Middle Colic Artery Aneurysm.

We report herein the successful laparoscopic resection of an asymptomatic 3-cm middle colic artery aneurysm in a young woman. Endovascular treatment represents nowadays the first-line option facing visceral artery aneurysm, but in this case, embolization was excluded because of hostile anatomy. Advantages of laparoscopic approach were the safe resection of the aneurysm with immediate evaluation of the bowel tolerance and the possibility of a histological examination of the arterial wall, without the disadvantages of laparotomy.

Percutaneous cryoablation of symptomatic venous malformations as a second-line therapeutic option: a five-year single institution experience.

Purpose: To report the mid-term outcomes of percutaneous cryoablation (PCA) performed as second-line therapeutic option of venous malformations (VM).

Material And Methods: From 2011 to 2015, PCA was offered in 24 patients (mean age: 31 years, range: 12-64) as second-line treatment for recurrence of symptoms after sclerotherapy and when resection was not possible (due to lesion location or previous failure) or refused by the patient. Adverse effects were recorded, disease-free survival (DFS) and local tissue control (LTC) rates were calculated based on symptoms and volume evolution.

Combination of Chimneys and Fenestrated Endografts in the Treatment of Complex Aortic Aneurysms.

Purpose: To present early results of fenestrated endovascular aneurysm repair (FEVAR) combined with chimney grafts in a high-volume center.

Methods: From July 2011 to July 2016, 45 patients (mean age 73.0±8.

Presentation, diagnosis, and management of popliteal artery entrapment syndrome: 11 years of experience with 61 legs.

Popliteal artery entrapment syndrome (PAES) is still underdiagnosed yet it may significantly interfere with lifestyle, especially among young sportspeople, with symptoms like intermittent claudication. Although case reports and small case series are sometimes published, studies with larger populations are quite rare. This study summarizes our experience with PAES on 61 limbs (35 patients) over a period of 11 years, describing the demographics, the disease, and the diagnostic and therapeutic methods used with PAES patients.

Embolization for persistent type IA endoleaks after chimney endovascular aneurysm repair with Onyx.

Purpose: The purpose of this study was to determine retrospectively the safety and technical success rate of embolization using ethylene vinyl alcohol copolymer (Onyx) for persistent type 1A endoleaks after chimney endovascular aneurysm repair (EVAR) for complex aortic aneurysms.

Material And Methods: Nine consecutive patients (6 men, 3 women) with a mean age of 78.6 years (range: 62-87 years) presenting with persistent type IA endoleaks after chimney EVAR and an increase of aneurysm size were treated using transarterial embolization with Onyx.

Results of the French Multicentric Study of ANACONDA™ Fenestrated Endografts in the Treatment of Complex Aortic Pathologies (EFEFA Registry).

Background: Most of the experience on fenestrated endovascular aneurysm repair involves the custom-made Zenith endograft (Cook). The fenestrated Anaconda endograft (Vascutek) was introduced with the potential advantages of complete repositioning and lack of stent material on the main aortic body for more versatility. However, few data are available.

Percutaneous Image-Guided Cryoablation as Second-Line Therapy of Soft-Tissue Venous Vascular Malformations of Extremities: A Prospective Study of Safety and 6-Month Efficacy.

Purpose: To report the safety and short-term efficacy of percutaneous image-guided cryoablation performed as second-line therapy of venous vascular malformations (VVM) of extremities.

Materials And Methods: In this non-blinded, no-randomized trial, cryoablation was proposed in 14 patients presenting with symptomatic VVM for recurrences after treatment. Eligibility criteria were: cryoablation feasible, localization at least 5 mm from skin and nerves, absence of contra-indication for anesthesia.

Influence of Anatomic Angulations in Chimney and Fenestrated Endovascular Aneurysm Repair.

Background: The lack of widespread availability of Fenestrated endovascular aneurysm repair (F-EVAR) encouraged alternative strategies. Hence, Chimney graft (CG)-EVAR spread when costs, manufacturing delays, or anatomy preclude F-EVAR. Our objective is to evaluate CG- and F-EVAR outcomes depending on the angulation of target renal arteries and hostility of iliac accesses in order to determine the potential impact of a choice made between both techniques on the basis of preoperative anatomic criteria.

Safety and efficacy of embolization using Onyx of persistent type II endoleaks after abdominal endovascular aneurysm repair.

Purpose: To retrospectively evaluate the safety and efficacy of embolization of persistent type II endoleaks occurring after abdominal endovascular aneurysm repair (EVAR) using ethylene vinyl alcohol copolymer (Onyx).

Material And Methods: Between 2008 and 2016, 28 consecutives patients (25 men, 3 women) with a mean age of 75.3years±9 (SD) (range: 59-90years) were treated for 29 persistent type II endoleaks with increasing aneurysm size>5mm occurring after EVAR.

Monocentric Evaluation of Chimney Versus Fenestrated Endovascular Aortic Repair for Juxtarenal Abdominal Aortic Aneurysm.

Background: With approval of on-label fenestrated (F-) endovascular aortic repair (EVAR), concerns regarding long-term patency and endoleaks (ELs) after chimney graft (CG)-EVAR were raised. To add supportive data on the value of this technique, we chose to report the midterm results of CG-EVAR in a single center with standardized methods and to compare them to F-EVAR.

Methods: A retrospective analysis of prospectively gathered data from January 2010 to January 2015 was conducted, and patients with excessive comorbidities for open repair treated by CG-EVAR or F-EVAR were included.

Six-year multicenter experience of standard endovascular treatment of critical limb ischemia in the era of drug-eluting devices.

Background: There has been increasing evidence to support the endovascular-first approach in the treatment of below-the-knee (BTK) lesions. Plain old balloon angioplasty (POBA), with bailout bare-metal stent scaffolding in case of flow limiting dissection or recoil, have been considered the standard treatment of choice but industries are continually developing innovative equipment and dedicated technologies, such as drug-eluting platforms whose use is increasingly extended, despite significant costs and lack of high-quality evidence to support a well-established strategy. This study's objective was to analyze the 6-year results of "standard" endovascular treatment of BTK lesions in the era of drug-eluting devices.

Chimney versus fenestrated endovascular aortic repair for juxta-renal aneurysms.

Introduction: Anatomical constrains, high price and manufacturing delay restrict fenestrated (F)-endovascular aortic repair (EVAR) to elective patients in specialized centers. Chimney graft (CG)-EVAR offers an alternative but uncertainties remain over target vessel's patency and type Ia endoleaks (ELs).

Evidence Acquisition: We reviewed the literature reporting F-EVAR and CG-EVAR for juxta-renal aneurysms between January 2005 and July 2016.

[Treatment of below the knee lesions: Broadening the limits of vascular surgery].

One third of patients with critical limb ischemia (CLI) has below the knee lesions and requires a restoration of direct blood flow into the foot. However, many of these patients are ineligible for open surgery. The primary goals thus become pain relief and limb salvage over patency.

Primary stenting for TASC C and D femoropopliteal lesions: one-year results from a multicentric trial on 203 patients.

Background: Recent advances in endovascular techniques have made it a seductive choice in the management of TASC C and D lesions. Currently, this tendency remains controversial, despite high success rates. The aim of the study was to regroup and harmonize the results of three surgical teams in 5 centers in order to obtain the largest series ever published on TASC C and D femoro-popliteal lesions primary stenting.

Sense and nonsense of bare metal stents below the knee.

Introduction: Critical limb ischemia (CLI) is increasingly present in daily practice, and diabetes is responsible for a preferential below the knee (BTK) localization of the disease. The objective was to determine if there is still a sense to BTK implantation of bare metal stents (BMSs) in CLI patients in the era of drug eluting strategies.

Evidence Acquisition: An extensive review of the literature was carried out over the last 15 years on the use of BMSs in BTK revascularization based on a PubMed (Medline), EMBASE and PubMed Central search.

Early cannulation of the Flixene™ arteriovenous graft.

Purpose: The aim of this review was to search for evidence of the efficiency of early cannulation of the Flixene™ (Maquet-Atrium Medical, Hudson, NH, USA) arteriovenous graft (AVG) in the current literature and to assess its patency and complication rates.

Methods: Searches in Pubmed, Medline, Embase and the Cochrane Library were performed using the following specific search terms: early cannulation AVG and/or Flixene™ graft. The primary outcomes were mean time to first cannulation and patency rates at 12 months.

Early Impact on Renal Parenchymal Vascularization of Chimney Grafts Versus Fenestrated Grafts.

Objective: The primary objective of this retrospective study was to analyze the early impact of chimney (CG) versus fenestrated grafts (FG) on renal parenchymal vascularization and function.

Methods: All consecutive patients with juxta-renal abdominal aortic aneurysm (JR-AAA) treated by endovascular repair from December 2013 to July 2014 at the vascular unit, Pellegrin University Hospital, Bordeaux, France, were included. Serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) were reported at baseline and at J2 for acute kidney injury (AKI) incidence, and at J7 for AKI staging (KDIGO criteria); renal resistive indices (RRI) were reported for renal parenchymal repercussion at J-1, J0, and J1.

Randomized Study of Noninferiority Comparing Prosthetic and Autologous Vein Above-Knee Femoropopliteal Bypasses.

Background: The main aim of this study was to compare the 5 years rates of secondary patency of above-knee femoropopliteal revascularizations with autologous veins or prosthetic grafts. The secondary objectives were to compare the rates of primary patency, limb salvage, morbidity, and mortality between the 2 groups.

Methods: This was a single-blind randomized study of noninferiority (ratio 1:1), carried out in 11 centers of vascular surgery with 2 parallel groups between July 2002 and November 2005.
