An uncommon presentation and hybrid approach for the management of an unruptured 8 cm common iliac artery aneurysm

ConclusionCommon Iliac Artery Aneurysms should be considered a differential diagnosis of lower abdominal mass. If presenting in this manner the aneurysm can be of significant size and at high risk of rupture, requiring urgent surgical intervention.

CONCLUSIONS: The numerical model of deployed fenestrated stent grafts is accurate for planning position of fenestrations. It has been validated in 51 patients, for whom fenestration locations were similar to the sizing performed by physicians and the planning centre. PMID: 31865026 [PubMed - as supplied by publisher]

ConclusionsWe defined human IVC morphology essential for endovascular therapy and developed parameters for fenestrated IVC endografts to address retrohepatic caval injuries in trauma patients. Although additional study and testing are required, this proof-of-concept study supports the hypothesis that exclusion of the most devastating retrohepatic IVC injuries can be achieved with a reasonable number of off-the-shelf fenestrated endografts. These findings form the basis for additional research toward the development of novel devices for endovascular therapy of these often lethal injuries.

Objectives The aim of this study was to compare image quality, conspicuity, and endoleak detection between single-energy low-kV images (SEIs) and dual-energy low-keV virtual monoenergetic images (VMIs+) in computed tomography angiography of the aorta after endovascular repair. Materials and Methods An abdominal aortic aneurysm phantom simulating 36 endoleaks (2 densities; diameters: 2, 4, and 6 mm) in a medium- and large-sized patient was used. Each size was scanned using single-energy at 80 kVp (A) and 100 kVp (B), and dual-energy at 80/Sn150kVp for the medium (C) and 90/Sn150kVp for the large size (D). VMIs+ at 40 k...

Introduction - Fusion imaging, which provides image guidance by overlaying preoperative 3D vessel anatomy from the preoperative CT scans onto live fluoroscopic images, is being used in endovascular repair to decrease radiation and contrast dose (1). Cloud-based image tracking software has been shown to be more accurate than hardware-tracking systems in these procedures(2). The aim of this study is to determine the accuracy of this technique when patient movement is greatest, for procedures done under local or regional anaesthesia.

Introduction: Surveillance after endovascular aneurysm repair (EVAR) is traditionally performed with computed tomography (CT) scans. US surveillance has been used as part of the surveillance protocol in our centre since 2011. The aim of this study was to evaluate whether US is able to detect post-EVAR complications as well as CT. Furthermore, freedom from cancer-related mortality was compared.

Introduction: EVAR (Endo Vascular Aortic Repair) is the first line therapy for the treatment of abdominal aortic aneurysms (AAA). The most frequent post-operative complications of EVAR are endoleaks (EL) that occur when blood leaks back into the aneurysm sac. Type II EL is the most frequent complication requiring lifelong surveillance by radiological imaging. Nowadays, according to guidelines, Computed Tomography Angiography (CTA) scan represents the gold standard modality of imaging to detect EL.

Introduction: Yearly imaging surveillance is recommended to all patients following endovascular aortic repair (EVAR) to detect complications requiring re-intervention. EVAR is currently the predominant technique for elective infrarenal abdominal aortic aneurysm (AAA) repair in the Netherlands. Consequently, a cumulative amount of hospital visits for imaging surveillance will arise. This causes a burden on both patients and the healthcare system. We therefore aimed to study the re-intervention free survival and survival stratified for patients with and without yearly imaging surveillance.
