Total Transfemoral Branched Endovascular Thoracoabdominal Aortic Repair (TORCH2): Short-term and 1-Year Outcomes From a National Multicenter Registry.

Objective: The use of steerable sheaths to allow total transfemoral access (TFA) of branched endovascular repair (BEVAR) of thoracoabdominal aortic aneurysms has been proposed as an alternative to upper extremity access (UEA); however, multicenter results from high-volume aortic centers are lacking.

Materials And Methods: The Total Transfemoral Branched Endovascular Thoracoabdominal Aortic Repair (TORCH2) study is a physician-initiated, national, multicenter, retrospective, observational registry (Clinicaltrials.gov identifier: NCT04930172) of patients undergoing BEVAR with a TFA for the cannulation of reno-visceral target vessels (TV).

Comparative Analysis of Patient-Specific Aortic Dissections through Computational Fluid Dynamics Suggests Increased Likelihood of Degeneration in Partially Thrombosed False Lumen.

Aortic dissection is a life-threatening vascular disease associated with high rates of morbidity and mortality, especially in medically underserved communities. Understanding patients' blood flow patterns is pivotal for informing evidence-based treatment as they greatly influence the disease outcome. The present study investigates the flow patterns in the false lumen of three aorta dissections (fully perfused, partially thrombosed, and fully thrombosed) in the chronic phase, and compares them to a healthy aorta.

Outcome Measures of In-Office Endovenous Radiofrequency Treatment of Varicose Vein Feasibility.

RFA is a relatively new treatment, approved by the FDA in 1999 and is a minimally invasive intervention that has become one of the most common alternatives due to its many advantages, including decreased pain, less morbidity, shorter hospital stay and faster return to work. We retrospectively analyzed a total of 503 limbs submitted for surgical interventions for VVs using the RFA, combined or not with surgical phlebectomies and sclerotherapy, in our institution between April 2012 and December 2020. The technical success was 99.

Preliminary results from an Italian National Registry on the outcomes of the Najuta fenestrated aortic arch endograft.

Background: Arch pathology represents one of the last frontiers in aortic aneurysm endovascular management. Several companies recently developed dedicated branched and fenestrated endografts specifically designed for the aortic arch, aiming to overcome some of the issues associated with standard thoracic endograft and supra-aortic vessels extra-anatomic debranching. This study aimed to evaluate early outcomes obtained with a custom-made fenestrated endograft approved for thoracic aortic aneurysms exclusion.

Incidence and Fate of Refractory Type II Endoleak after EVAR: A Retrospective Experience of Two High-Volume Italian Centers.

Introduction: The aim of the present study is to report the outcome of patients presenting an isolated type II endoleak (TIIEL) requiring reintervention and to identify clinical and anatomical characteristics potentially implicated in refractory TIIEL occurrence and fate. Materials and Methods: A multicenter retrospective study on TIIEL requiring reintervention was conducted between January 2003 and December 2020. Demographic and clinical characteristics, procedural technical aspects, reinterventions, and outcomes were recorded.

Outcomes of multibranched off-the-shelf stent graft in elective and urgent/emergent repair of complex aortic aneurysms with narrow internal aortic lumen.

Objective: To assess the initial clinical experience with a novel endograft system (NEXUS Aortic Arch Stent Graft System) designed to treat aortic arch pathologies and address the morphology and hemodynamic challenges of the aortic arch.

Summary Background Data: The aortic arch remains the most challenging part of the aorta for both open and endovascular repair. Transcatheter aortic arch repair has the potential to significantly reduce surgical risks.

EVAR with Aortic Placement of a Single JOTEC E-iliac Stent-graft System in a Patient with Poliomyelitis Aortoiliac Deformities.

Small-sized vessels can represent a contraindication to standard endovascular aortic repair (EVAR), and more specifically, aortoiliac deformities resulting from poliomyelitis may add an adjunctive challenge for total endovascular repair. Herein we report a case of a 62-year-old man with a 55 mm abdominal aortic aneurysm (AAA) and a history of poliomyelitis. More specifically, a computed tomography angiogram (CTA) showed a very narrow infrarenal aortic neck, measuring 13 mm in maximum diameter, and severely atrophic external iliac and common femoral arteries.

The Italian Multicentre Registry of Fenestrated Anaconda™ Endografts for Complex Abdominal Aortic Aneurysms Repair.

Objective: The aim was to describe the outcomes of the Anaconda™ Fenestrated endograft Italian Registry for complex aortic aneurysms (AAAs), unsuitable for standard endovascular aneurysm repair (EVAR).

Methods: Between 2012 and 2018 patients with a proximal neck unsuitable for standard EVAR, treated with the fenestrated Anaconda™ endograft, were prospectively enrolled in a dedicated database. Endpoints were peri-operative technical success (TS) and evaluation of type Ia/b or 3 endoleaks (T1/3 EL), target visceral vessel (TVV) occlusion, re-interventions, and AAA related mortality at 30 days, six months, and later follow up.

Early Renal Function Alterations in Renal Branches vs. Renal Fenestrations - A Dynamic Scintigraphy Based Prospective Study.

Objective: The objective of this prospective single centre study was to assess whether branches and fenestrations have different outcomes on renal function in the early phase.

Methods: From March 2018 to June 2019, 67 patients who underwent elective fenestrated and branched endovascular aneurysm repair (F/BEVAR) procedures were enrolled in this study. The patients were divided into two groups according to the renal bridging component configuration (fenestration vs.

Late failure of a Nellix endoprosthesis treated with the t-Branch off-the-shelf multibranched stent graft.

A 66-year-old man arrived at our emergency department 3 years after an endovascular aneurysm sealing procedure performed at another center. Computed tomography angiography showed distal migration of a Nellix endoprosthesis (Endologix, Irvine, Calif) and a posterior contained rupture. The left kidney was excluded by an occluded iliac-left renal bypass, which was performed at the time of the Nellix implantation because of unintended coverage.

Type 2 Endoleak Incidence and Fate After Endovascular Aneurysms Repair in a Multicentric Series: Different Results with Different Devices?

Background: The aim of this work is describing incidence and fate of type 2 endoleaks (T2ELs) in a multicentric cohort of patients treated by endovascular aneurysms repair using the Ovation device (Endologix) and comparing them with a group treated using the Excluder (W. L. Gore & Associates).

The "bare branch" for safe spinal cord ischemia prevention after total endovascular repair of thoracoabdominal aneurysms.

Objective: Staged endovascular treatment of thoracoabdominal aortic aneurysms (TAAAs) with temporary perfusion of the sac through a branch left unstented or a dedicated branch is a strategy intended to reduce the risk of postoperative spinal cord ischemia (SCI). However, potential complications of this approach are aneurysm sac progression between stages, visceral embolism, and occlusion or displacement of components. We here present the "bare branch" technique, a safe adjunct to TAAA repair in terms of interstage complications.

Standard "off-the-shelf" multibranched thoracoabdominal endograft in urgent and elective patients with single and staged procedures in a multicenter experience.

Objective: The objective of this study was to assess immediate and midterm outcomes for urgent/emergent and elective patients with thoracoabdominal aortic aneurysms (TAAAs) treated with the first commercially available "off-the-shelf" multibranched endograft for endovascular aneurysm repair, with a single-step or a staged surgical approach.

Methods: A multicenter, nonrandomized, retrospective study was conducted of TAAA patients grouped by urgent/emergent and elective treatment with multibranched endograft for endovascular aneurysm repair at 13 Italian centers from November 2012 to August 2016. Urgent/emergent repair was classified as rupture in 16%, impending rupture in 9%, pain in 53%, or a maximum TAAA diameter ≥80 mm in 22%.
