Objectives Correct sizing of endoprostheses used for the treatment of abdominal aortic aneurysms is important to prevent endoleaks and migration. Sizing requires several steps and each step introduces a possible sizing error. The goal of this study was to investigate the magnitude of these errors compared to the golden standard: a vessel phantom. This study focuses on the errors in sizing with three different brands of computed tomography angiography scanners in combination with three reconstruction software packages...

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications...

Complexity of the spatial configuration of an aortic implant with bifurcation in the distal part is related to changes in blood hemodynamic in the area of bifurcation which may disturb blood flow and lead to thrombus formation. This study was designed to characterize parameters which define spatial configuration of an aortic implant for which the risk of thrombus formation is the smallest. We used AngioCT data from 74 patients, aged 55 ±10 years, after endovascular procedure to prepare 3D geometries of stent-grafts...

A 66-year-old man developed an extended chronic type B dissection involving the thoraco-abdominal aorta with a large entry at the aortic arch and a patent false lumen. We performed triple-stage endovascular repair which included the vascular plug, endovascular aortic repair and hybrid thoracic endovascular aortic repair. His postoperative course was uneventful and the false lumen was finally thrombosed.

BACKGROUND: Endovascular aortic repair (EVAR) has emerged as a standard of care for abdominal aortic aneurysm (AAA) repair. However, real-world evidence to compare this technology to open aortic repair (OAR) is limited. Major gaps exist related to long-term outcomes of therapies worldwide. METHODS: Health insurance claims data of Germany's third largest insurance provider, DAK-Gesundheit, were used to determine outcomes after interventions for intact AAA (iAAA) and ruptured AAA (rAAA)...

BACKGROUND: Previous studies comparing endografts with suprarenal and infrarenal fixation for endovascular abdominal aortic aneurysm repair (EVAR) have found conflicting results and did not account for differences in patient selection. This study aims to evaluate the differences in outcomes among surgeons who routinely use either suprarenal or infrarenal fixation, as well as all surgeons in the Vascular Study Group of New England (VSGNE). METHODS: All patients undergoing EVAR in the VSGNE from 2003 to 2014 were identified...

The implementation of a new clinical service is associated with anxiety and challenges that may prevent smooth and safe execution of the service. Unexpected issues may not be apparent until the actual clinical service commences. We present a novel approach to test the new clinical setting before actual implementation of our endovascular aortic repair service. In-situ simulation at the new clinical location would enable identification of potential process and system issues prior to implementation of the service...

BACKGROUND: Thoracic aortic mural thrombus (TAMT) of the descending aorta is rare but can result in dramatic embolic events. Early treatment is therefore crucial; however, there is not a consensus on ideal initial treatment. METHODS: A review of the literature using PubMed was conducted, and all relevant publications describing descending TAMT of the past 15 years were reviewed. Variables included for this analysis were presentation, initial treatment strategy employed, outcome measures of thrombus resolution or regression, recurrence of symptomatic emboli, and mortality...
