Safety and efficacy of an innovative external support device for de novo arterio-venous fistula creation: a French bicentric experience.

Background: The aim of this study was to evaluate the safety and efficacy of VasQ, a permanent extravascular nitinol vascular support device, implanted around the anastomosis of de novo arteriovenous fistulas (AVF), in consecutive patients.

Methods: This was a French prospective bicentric study. All patients with an indication for creation of a distal or proximal end to side AVF performed by supervised trainee were eligible.

Customizable modification of banding with external stenting for arteriovenous fistula flow reduction.

We performed a single-center retrospective study of prospectively collected data for all patients who had flow reduction surgery with FRAME FR between November 2020 and January 2021. Ten patients had arteriovenous fistula flow reduction surgery with this technique. One patient had a distal fistula, whereas nine were within the cubital fossa.

Comparison of surgical versus percutaneously created arteriovenous hemodialysis fistulas.

Objective: The aim of the present study was to compare the results between percutaneous arteriovenous fistulas (p-AVFs) created with the Ellipsys device (Ellipsys Vascular Access System; Avenu Medical, San Juan Capistrano, Calif) and surgical arteriovenous fistulas (s-AVFs).

Methods: A single-center retrospective comparative study of the first 107 patients who had undergone p-AVF creation with the Ellipsys system from May 2017 to May 2018 with an equal number of consecutive patients who had undergone s-AVF creation in our center during the same period. The primary endpoints included the maturation and patency rates.

Midterm results of percutaneous arteriovenous fistula creation with the Ellipsys Vascular Access System, technical recommendations, and an algorithm for maintenance.

Objective: The aim of this study was to report our midterm results of percutaneous arteriovenous fistula (pAVF) creation using the Ellipsys (Avenu Medical, San Juan Capistrano, Calif) device and to present technical recommendations and our algorithm of pAVF maintenance.

Methods: A single-center comprehensive database of all consecutive predialysis and end-stage renal disease patients who had a pAVF creation with the Ellipsys device was reviewed retrospectively. Study end points included technical success, maturation, functional patency, and required interventions.

Optimising Aortic Endovascular Repair in Patients with Marfan Syndrome.

Objective: In Marfan syndrome (MFS) patients, endovascular repair carries a risk of aortic wall injury, which may result in retrograde aortic dissection, dilatation, or false aneurysm at the landing zones. It was hypothesised that potentially these complications may be avoided using modified practices. This study aimed to describe experience of a specific protocol for endovascular aortic repair in patients with MFS.

Percutaneous arteriovenous fistulae: Technique, feasibility and results.

Patients with end-stage renal disease that require chronic haemodialysis need a reliable vascular access. Unanimously, native arteriovenous fistulae are considered to be the most reliable access for patients with reasonable life expectancy. For the last 60 years arteriovenous fistulae have been created surgically at the wrist or the elbow with variable rates of success, maturation problems, reinterventions and complications, making this field of surgery particularly challenging and full of scientific controversies.

False lumen embolization in chronic aortic dissection promotes thoracic aortic remodeling at midterm follow-up.

Objective: Failure of thoracic endovascular aortic repair (TEVAR) in chronic aortic dissections can be partially explained by retrograde false lumen (FL) flow through distal re-entry tears. After implantation of a thoracic stent graft, FL thrombosis occurs in less than 50% of the cases. The objectives of this study were to describe the feasibility and outcomes of FL embolization in patients with chronic aortic dissections.

Impact of Stent-Graft Oversizing on Gutter Areas after Chimney Graft Repair for Complex Abdominal Aortic Aneurysms.

Background: The aim of this retrospective study was to examine the impact of graft oversizing on gutter area and stent compression in chimney graft (CG) for complex abdominal aortic aneurysm (CAAA) repair. The influence of stent-graft oversizing on type Ia endoleaks and bridging stent occlusion rates was also examined.

Methods: Preoperative and postoperative computed tomographic angiography scans of patients requiring CGs for CAAA between June 2009 and April 2013 in our institution were analyzed.

Surgical revascularization of the celiac artery for persistent intestinal ischemia in short bowel syndrome.

Background And Objectives: Without prompt superior mesenteric artery (SMA) revascularization, acute mesenteric ischemia (AMI) frequently leads to death or short bowel syndrome (SBS). In SBS patients, persistent or chronic intestinal ischemia (PII) of the remnant bowel can lead to recurrences of AMI. Since SMA revascularization is sometimes unfeasible, celiac artery (CA) revascularization may improve blood supply to the remnant bowel.

Initial Experience with Percutaneous Angioplasty of the Common Femoral Artery in De Novo Stenotic Lesions.

Background: The aim of this study was to report an initial experience with percutaneous transluminal angioplasty (PTA) in de novo stenotic lesions of the common femoral artery (CFA).

Methods: A retrospective analysis for 34 consecutive patients was conducted. The follow-up consisted of clinical evaluation and color duplex ultrasound scan (CDU) 1, 6, and 12 months after the procedure.

Percutaneous radial access for peripheral transluminal angioplasty.

Objective: The radial approach is currently gaining popularity in the setting of coronary percutaneous transluminal angioplasty (PTA) because it decreases the incidence of vascular complications. This study reports our initial results with radial access for peripheral PTA.

Methods: Between November 2011 and January 2014, we performed peripheral PTA in 526 patients.

Chimney stent graft for endovascular sealing of a pararenal aortic aneurysm.

Chimney endovascular aneurysm repair is still a controversial treatment of complex aortic aneurysms. Stent-graft patency and type-I endoleaks are the main challenges that temper this bailout technique. Endovascular aneurysm sealing (EVAS) consists of anchoring and sealing the device within the aneurysm sac.

Long-term preservation of native arteriovenous dialysis fistulas.

Preservation of native arteriovenous fistulas (AVFs) in the long term can be technically challenging. Various anatomic or functional problems can occur and multiple open and/or endovascular interventions may be required for extended preservation of native accesses. In this report, we review vascular access maintenance in a 72-year-old woman during a 5-year period.

De novo periaortic fibrosis after endovascular aortic repair.

We report a case of a 63-year-old man presenting with abdominal pain and hydronephrosis secondary to periaortic fibrosis (PAF) 8 months after an endovascular aortic repair (EVAR) using a woven polyester bifurcated graft. De novo delayed PAF after open repair is rare and even more infrequent after EVAR. All 3 previously reported cases occurred after woven polyester grafts and no reported cases after polytetrafluorethylene grafts.

Elective treatment of abdominal aortic aneurysm is reasonable in patients >85 years of age.

Background: The numbers of patients >85 years of age referred for abdominal aortic aneurysm (AAA) repair have increased in recent decades. With the population aging, increased screening of AAA, and introduction of less invasive surgical techniques, vascular surgeons will be treating more elderly patients. Few data are available for estimating the risks and benefits of prophylactic repair among those with such an advanced age.

Tagliatelle technique for arteriovenous fistula creation using a great saphenous vein semipanel graft.

Lower limb arteriovenous (AV) access creation can be attempted in patients where upper limb options are exhausted. Utilization of the great saphenous vein as a conduit for AV access has been limited due to its small diameter and resistance to dilatation. Lower limb AV fistulas today are mostly either prosthetic grafts with high rates of infection and thrombosis or transposition of the femoral vein that can lead to limb-threatening venous hypertension.
