Feasibility of the Application of Holographic Augmented Reality in Endovascular Surgery Using Microsoft HoloLens Head-Mounted Display.

Objectives: Advances in virtual, augmented (AR) and mixed reality have led to the development of wearable technologies including head mounted displays (HMD). The aim of this study was to investigate the feasibility to use HMD during endovascular surgery.

Methods: We propose an adaptation of AR-HMD using Microsoft HoloLens.

Applications of Head-Mounted Displays and Smart Glasses in Vascular Surgery.

Objectives: Advances in virtual, augmented and mixed reality have led to the development of wearable technologies including head mounted displays (HMD) and smart glasses. While there is a growing interest on their potential applications in health, only a few studies have addressed so far their use in vascular surgery. The aim of this review was to summarize the fundamental notions associated with these technologies and to discuss potential applications and current limits for their use in vascular surgery.

Endovascular aneurysm sealing as an alternative for the treatment of failed endovascular aneurysm repair.

Objective: The Nellix EndoVascular Aneurysm Sealing (EVAS) system has offered a novel approach in the treatment of abdominal aortic aneurysm (AAA). While it is currently indicated as a primary procedure in patients with infrarenal AAA with suitable anatomy according to the indications for use, a few studies aimed to address its potential interest in failed endovascular aneurysm repair (EVAR). The aim of this systematic review was to analyze the postoperative outcomes of patients with prior EVAR who underwent EVAS.

A fully automated pipeline for mining abdominal aortic aneurysm using image segmentation.

Imaging software have become critical tools in the diagnosis and the treatment of abdominal aortic aneurysms (AAA). The aim of this study was to develop a fully automated software system to enable a fast and robust detection of the vascular system and the AAA. The software was designed from a dataset of injected CT-scans images obtained from 40 patients with AAA.

Endovascular Aneurysm Sealing and Chimney Endovascular Aneurysm Sealing in the Treatment of Type Ia and Type III Endoleaks After Endovascular Aneurysm Repair.

Background: The aim of this study was to report the treatment of type Ia and type III endoleaks after endovascular aneurysm repair (EVAR) or chimney EVAR using endovascular aneurysm sealing (EVAS) and chimney EVAS.

Methods: Ten consecutive patients who underwent the EVAS procedure to treat endoleaks after EVAR were retrospectively included between July 2015 and July 2017. Technical success of EVAS was defined as a successful sealing of the Nellix endograft with visceral vessel patency on intraoperative completion angiography.

Impact of Polar Renal Artery Coverage on Early Renal Function after Chimney Endovascular Aortic Aneurysm Repair.

Purpose: To evaluate impact of polar renal artery coverage on early renal function after chimney endovascular aneurysm repair (EVAR).

Materials And Methods: Consecutive patients who underwent chimney EVAR for treatment of asymptomatic juxtarenal abdominal aortic aneurysm were retrospectively included. Estimated glomerular filtration rate (eGFR) was recorded before the intervention and at 1-, 5-, 7-, and 30-day follow-up.

Diabetes mellitus is not associated with worse vascular outcome following percutaneous transfemoral transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) is an alternative to open surgical aortic valve replacement and the impact of diabetes on vascular outcomes is worth of investigation. The aim of our study was to determine if diabetic patients had distinct pre-operative characteristics compared to non-diabetics and to evaluate the impact of the disease on vascular outcomes. Four hundred consecutive patients who underwent TAVI with percutaneous transfemoral access were retrospectively included.

Endovascular Aneurysm Sealing of a Collapsed and Thrombosed Aortic Stent-Graft With Renovisceral Chimney Stent-Grafts.

Purpose: To report the use of the Nellix endovascular aneurysm sealing (EVAS) system in the management of proximal stent-graft collapse associated with thrombosis following endovascular aneurysm repair (EVAR).

Case Report: A 76-year-old man was admitted for proximal collapse of an aortic extension following bifurcated AFX stent-graft implantation associated with chimney grafts in both renal arteries and the superior mesenteric artery 1 month prior. Imaging identified thrombosis of the aortic stent-graft and the iliac limbs.

A 7-Year Single-Center Experience of Transfemoral TAVI: Evolution of Surgical Activity and Impact on Vascular Outcome.

Transcatheter aortic valve implantation (TAVI) has become a well-established alternative to open surgery to treat aortic stenosis. We describe our 7-year TAVI experience using transfemoral access and identity changes in surgical activity and evaluate its impact on postoperative vascular outcomes. Consecutive patients (N = 340) who underwent TAVI with percutaneous transfemoral access were retrospectively included and divided into 4 quartiles according to the date of intervention.

Surgical Management of Percutaneous Transfemoral Access to Minimize Vascular Complications Related to Transcatheter Aortic Valve' Implantation.

Transcatheter aortic valve implantation (TAVI) is associated with substantial rates of vascular complications. The aim of our study is to describe the surgical management of percutaneous transfemoral access by a vascular surgeon and to report the 30-day postoperative vascular complications and mortality. Perioperative procedures to manage the femoral access site were recorded retrospectively from 220 consecutive patients who underwent TAVI.

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.

Angiographic Analysis of Vascular Integrity After Percutaneous Closure Using Prostar XL Device During Transcatheter Aortic Valve Implantation.

Introduction: Percutaneous closure devices are commonly used to achieve hemostasis during endovascular procedures including transcatheter aortic valve implantation (TAVI). The aim of our study was to investigate the quality of the percutaneous femoral arterial closure by Prostar XL device using a systematic peroperative angiographic control at the end of TAVI procedure.

Materials And Methods: Two hundred seventeen consecutive patients (mean age: 84 [6.

Complex Iatrogenic Dissection Complicating Thoracic Endovascular Aneurysm Repair.

Background: To report one the most feared complication of thoracic endovascular aneurysm repair (TEVAR); a retrograde aortic dissection who can involve the aortic arch or ascending aorta, which require commonly coextensive open surgical repair.

Case Reports: We report 2 cases of combined retrograde and antegrade dissection after endovascular treatment of an aneurysm of the descending aorta. In both cases, a dissection was identified at short-term follow-up; which required open surgical repair in one case and an additional endovascular treatment for the second case.
