Spinal Cord Protection During Thoracic and Thoracoabdominal Endovascular Aortic Repair: 5-Year Results of a Preventive Protocol Including Prophylactic Cerebrospinal Fluid Drainage in High-Risk Patients.

Purpose: Spinal cord injury (SCI) is a devastating complication of thoracoabdominal aortic (TAA) repair. The use of prophylactic cerebrospinal fluid drainage (CSFD) as part of a protective protocol during endovascular repair is controversial. This article reports the results of the prophylactic use of CSFD as part of the of a prevention protocol implemented in 2016.

Comparison of Short and Midterm Aortic Reinterventions in Acute Type A Aortic Dissection Treated by Frozen Elephant Trunk or Conventional Arch Repair.

Background: Long-term outcomes after acute type A aortic dissection (ATAAD) are related to remodelling of the descending thoracic aorta and aortic reinterventions. We compared the impact of an extensive repair at the index procedure using the Frozen Elephant Trunk (FET) technique, versus a conventional arch repair, on long-term remodelling of the descending thoracic and reintervention related to the aorta.

Methods: Consecutive patients who underwent conventional arch repair (conventional group) or FET repair (FET group) for an ATAAD from September 2018 to November 2021 were included.

A comparison of suprarenal and infrarenal fixation and renal volumetric analysis after endovascular aneurysm repair.

Objective: Clinical and experimental studies of the stent-graft fixation impact on the renal volume after endovascular abdominal aortic aneurysm repair have focused on glomerular filtration rate, and the results were controversial. The aim of this study was to analyze and compare the impact of the suprarenal (SRF group) and infrarenal (IRF group) stent-graft fixation on the renal volume.

Methods: Between December 2016 and December 2019, all patients treated with endovascular aneurysm repair were retrospectively analyzed.

Obesity is Not Associated with Adverse Perioperative or Poorer Clinical Outcomes following Thoracic and Fenestrated-Branched Endovascular Aortic Repair.

Background: Obesity is a risk factor for higher morbidity and mortality following open aortic repair but currently there is limited literature on its impact on clinical and procedural outcomes following thoracic endovascular aortic repair (TEVAR) and branched-fenestrated endovascular aortic repair (B-FEVAR).

Methods: We conducted a retrospective case-control analysis of a prospectively collected nonrandomized database to evaluate the effects of obesity on procedural and clinical outcomes after B-FEVAR/TEVAR in treatment of pararenal/thoracoabdominal aortic aneurysm and dissection at the University hospital of Nantes (France) between January 2016 and December 2021. Patients were divided in 2 groups according to their body mass index (BMI) and the rate of technical success, complications (renal, pulmonary, cardiac, and neurological events), 30-day and long-term survival, freedom from target vessel instability and reintervention were compared.

3D-printed model of simulation for acute thrombus removal in peripheral arteries.

Background: Surgical training and evaluation of medical devices require simulation models. The aim of this study was to assess a 3D-printed model as a training model for peripheral endovascular procedures, including thromboaspiration in acute limb ischemia (ALI).

Methods: The 3D-simulation model was modeled from an aorta and lower limbs CT scan by segmentation of the arterial light.

Fusion Imaging Guidance Does Not Affect Radiation Exposure During Endovascular Procedures for Lower Extremity Arterial Disease: A Randomized Controlled Trial.

Purpose: Radiation exposure for vascular interventionalists is still a concern. The aim of this study was to assess the value of advanced imaging guidance on radiation exposure and iodinated contrast volume during endovascular treatment of lower extremity arterial disease (LEAD).

Materials And Methods: It was a prospective, randomized, monocentric, pilot, single-operator study, conducted from June 2018 to October 2019.

Single Centre Experience in Open and Endovascular Treatment of Renal Artery Aneurysms.

Background: The true incidence and natural history of renal artery aneurysm (RAA) remain unclear and still exists controversy over indication for treatment. Several techniques of conventional surgical reconstructions are described in literature, and more recently endovascular therapies have been reported with satisfying results and lower complication rate. This paper aims to investigate the outcomes of both endovascular and open repair of RAA achieved in a single institution involving 3 medical teams (urology, vascular surgery and neuroradiology).

Automated Image Fusion Guidance during Endovascular Aorto-Iliac Procedures: A Randomized Controlled Pilot Study.

Background: The benefits of imaging guidance using a new fully automated fusion process (CYDAR) have been demonstrated during endovascular aortic aneurysm repair, but little is known about its use during aorto-iliac occlusive disease endovascular revascularization. The aim of this study was to evaluate the influence of CYDAR image fusion guidance during endovascular treatment of symptomatic aorto-iliac occlusive lesions, compared with control patients treated using standard 2D fluoroscopy alone.

Methods: This is a single-center randomized controlled pilot study that recruited patients undergoing aorto-iliac endovascular revascularization.

Bare Stents for Iliac Chronic Total Occlusions ("TELIS"): A Prospective Cohort Study with a Midterm Follow-up.

Background: This study aims to assess primary bare stenting for iliac chronic total occlusions (CTOs) with midterm follow-up.

Methods: From April 2013 to May 2016, all patients presenting with symptomatic iliac CTO were treated endovascularly and included in a prospective single-center cohort. Common iliac CTOs were treated with balloon-expandable bare-metal stents.
