Fibromuscular dysplasia (FMD) commonly affects the renal and cervical arteries but has been described to affect other vascular beds as well. The prevalence of and clinical characteristics associated with multisite FMD (string-of-beds or focal stenoses affecting at least 2 vascular beds) are not known. In the prospective ARCADIA registry (Assessment of Renal and Cervical Artery Dysplasia), symptomatic patients with renal artery (RA) FMD underwent tomographic- or magnetic resonance-angiography from the aortic arch to the intracranial arteries and those with cervical FMD from the diaphragm to the pelvis...

OBJECTIVE: Although few studies have reported outcomes after branched or fenestrated endovascular aortic aneurysm repair (FEVAR) of abdominal aortic aneurysms involving visceral vessels (AAA-Vs), no multi-institutional study has compared FEVAR with open surgery (OS) for AAA-Vs. Our objective was to compare 30-day outcomes after FEVAR vs OS for AAA-Vs. METHODS: Patients who underwent FEVAR (n = 535) and OS (n = 1207) for elective AAA-Vs were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) 2008 to 2013 database...

A total of 576 patients underwent endovascular aneurysm repair using main body devices for treatment of abdominal aortic aneurysms or iliac artery aneurysms. During follow-up, type IIIb endoleaks caused by fabric tear occurred in six patients (1.0% [6/576]). The device used was Zenith (Cook Medical, Bloomington, Ind) in five cases and Talent (Medtronic, Santa Rosa, Calif) in one case. All endoleaks were close to the flow divider of the main body devices. The distance between the lower renal artery and the top end of the contralateral leg was 53 ± 14 mm...

A 52-year-old man was admitted with an incidentally detected right renal artery aneurysm (RAA). Computed tomographic angiography with three-dimensional reconstruction revealed that the aneurysm was 2.2 cm in diameter and located at the renal hilum. We performed hand-assisted laparoscopic nephrectomy with ex vivo repair of the RAA and auto-transplantation with minimal elongation of Gibson incision. The operation and postoperative course were uneventful. At last follow-up, the patient was alive with a well-functioning auto-transplant...

PURPOSE: To examine the influence of device positioning and infrarenal neck diameter on flow patterns in the Nellix endovascular aneurysm sealing (EVAS) system. METHODS: The transition of the aortic flow lumen into two 10-mm-diameter stents after EVAS creates a mismatched area. Flow recirculation may affect local wall shear stress (WSS) profiles and residence time associated with atherosclerosis and thrombosis. To examine these issues, 7 abdominal aortic aneurysm flow phantoms were created, including 3 unstented controls and 3 stented models with infrarenal neck diameters of 24, 28, and 32 mm...

C Stelzner, N Abolmaali, U Hecker, S Schellong
Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound...

INTRODUCTION: Visceral and renal artery aneurysms (VRAAs) are an uncommon clinical entity but carry a risk of rupture with associated morbidity and mortality. The rupture risk is particularly high when the aneurysms are large, of unfavourable morphology or in the setting of pregnancy and perioperative period. Endovascular approaches are now first line in the treatment of VRAA, but conventional techniques may be ineffective in excluding aneurysms with unfavourable anatomy such as those with wide necks or at arterial bifurcation points...

BACKGROUND: The cumulative amount of iodinated-contrast-medium necessary for EVAR planning, operative procedure and subsequent follow-up is a threat for the onset of end stage renal disease in patients with pre-operative impaired kidney function. Purpose of this study is to describe a mini-invasive approach aimed to minimize the exposure of these patients to iodinated-contrast-medium and the subsequent risk of renal function worsening. METHODS: From 2012 to 2015, all patients with abdominal aortic aneurysm (AAA) at high-surgical risk and fit for standard endovascular repair (simple aortic-iliac anatomy: proximal and distal neck length ≥15mm, no severe angulation), underwent EVAR through the following "near-zero contrast" approach, if their glomerular filtration rate (GFR) was <30 mL/min: pre-operative planning was performed by non-contrast enhanced computed tomography (CT) and duplex-ultrasound (DU); the origin of renal/hypogastric arteries and aortic bifurcation was evaluated and matched with vertebral bone landmarks and the endograft deployed accordingly, using < 20cc of isotonic iodinate-contrast-medium and contrast-enhancement-DU (CEUS)...

OBJECTIVE: Aortic reconstruction for complex thoracoabdominal aortic aneurysms (TAAAs) can be challenging, especially in patients with connective tissue disorders (CTDs) in whom tissue fragility is a major concern. Branched graft reconstruction is a more complex operation compared with inclusion patch repair of the aorta but is frequently necessary in patients with CTDs or other pathologies because of anatomic reasons. We describe our institutional experience with open branched graft reconstruction of aortic aneurysms and compare outcomes for patients with CTDs vs degenerative pathologies...
