BACKGROUND: People with abdominal aortic aneurysm who receive endovascular aneurysm repair (EVAR) need lifetime surveillance to detect potential endoleaks. Endoleak is defined as persistent blood flow within the aneurysm sac following EVAR. Computed tomography (CT) angiography is considered the reference standard for endoleak surveillance. Colour duplex ultrasound (CDUS) and contrast-enhanced CDUS (CE-CDUS) are less invasive but considered less accurate than CT. OBJECTIVES: To determine the diagnostic accuracy of colour duplex ultrasound (CDUS) and contrast-enhanced-colour duplex ultrasound (CE-CDUS) in terms of sensitivity and specificity for endoleak detection after endoluminal abdominal aortic aneurysm repair (EVAR)...

OBJECTIVE: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions. METHODS: Data of 156 consecutive EVAR patients with short (<15 mm) HN, treated with the Endurant device (Medtronic Cardiovascular, Santa Rosa, Calif) at three European academic vascular centers between 2007 and 2015, were collected and retrospectively analyzed...

PURPOSE: To define the risk for type II endoleak (EII) after endovascular aneurysm repair (EVAR) based on preoperative anatomical characteristics. METHODS: Between January 2008 and December 2015, 189 patients (mean age 78.4±7.6 years; 165 men) underwent standard EVAR. Mean aneurysm diameter was 5.7±0.7 cm and mean volume 125.2±45.8 cm(3). Patients were assigned to the "at-risk" group (n=123, 65%) when at least one of the following criteria was present: patency of a >3-mm inferior mesenteric artery (IMA), patency of at least 3 pairs of lumbar arteries, or patency of 2 pairs of lumbar arteries and a sacral artery or accessory renal artery or any diameter patent IMA; otherwise, patients were entered in the "low-risk" group (n=66, 35%)...

OBJECTIVE: Endovascular aortic aneurysm repair (EVAR) with a fenestrated device (FEVAR) allows an extension of the proximal sealing zone above the renal arteries to an adequate, healthier segment of the aorta. This feature makes FEVAR an option to treat patients with a diseased aortic neck or type Ia endoleak after EVAR. The aim of this investigation was to present a single-center experience with FEVAR for patients with an abdominal aortic endograft in situ compared with primary FEVAR...

INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...
