Extended Proximal Seal Zone During EVAR Predicts Aneurysm Sac Regression

Delayed Aneurysm Rupture After EVAR

Endovascular Aortic Aneurysm Repair (EVAR)

Over the past 20 years the availability of aortic stent-grafts has allowed a major step change in the management of abdominal aortic aneurysms (AAA). Prior to this open surgical resection, first described by Charles Dubost in 1950, was the mainstay of AAA management(1). For elective cases open surgical repair has now largely been superseded by the deployment of a covered stent (stent-graft) thr...

The effect of injectable biocompatible elastomer (PDMS) on the strength of the proximal fixation of EVAR-grafts An in-vitro study

Purpose: One of the major concerns in the long-term success of EVAR is stent-graft migration, which can cause type I endoleak and even aneurysm rupture. Fixation depends on the mechanical forces between the graft and both the aortic neck and the blood flow. Therefore there are anatomical restrictions for EVAR, such as short and angulated necks. To improve the fixation of EVAR-grafts, elastomer ...

Mid-Term Results of EVAR in Severe Proximal Aneurysm Neck Angulation.

OBJECTIVE To determine if mid-term outcome following endovascular aneurysm repair (EVAR) with the Endurant Stent Graft (Medtronic, Santa Rosa, CA, USA) is influenced by severe proximal neck angulation. METHODS A retrospective case-control study was performed using data from a prospective multicenter database. All measurements were obtained using dedicated reconstruction software and center-lu...

FEATURED TECHNOLOGY: VELATM PROximAL ENDOGRAFT SYSTEm

The rapid acceptance of endovascular repair (EVAR) of abdominal aortic aneurysms (AAAs) over the past 15 years has been driven in large part by advancing endovascular skills, innovation in endograft technology, and physician expansion of the approach to patients with more complex anatomies.1 The challenges to EVAR remain, as is well documented in the clinical literature. Proximal neck morpholog...
