In the ongoing evolution of a categorization system for endoleak, authors propose term endotension to define persistent or recurrent pressurization aortic aneurysm sac after endovascular repair. Endotension is evidence that remains at risk rupture and should, therefore, be considered an indication secondary intervention. Management strategies grading are offered.

Purpose:To report our first clinical application of a new technique for in situ fenestration thoracic stent-graft. Case Report:After completing series vitro and vivo experiments, stent-graft was employed during endograft repair saccular aortic aneurysm 77-year-old woman. Because the would have covered left subclavian artery ostium, modified Zenith TX1 deployed then fenestrated transluminally using guidewire followed by serial cutting balloons, which created over LSA sufficiently large to...

Fenestrated endovascular repair of abdominal aortic aneurysms has been proposed as an alternative to open surgery for juxtarenal and pararenal aneurysms. At present, the evidence base this procedure is predominantly limited single-center or single-operator series. The aim study was present nationwide early results fenestrated in United Kingdom.All patients who underwent between January 2007 December 2010 at experienced institutions Kingdom(>10 procedures) were retrospectively studied by use...

The outcome of fenestrated endovascular aneurysm repair (F-EVAR) was evaluated.Between February 2003 and December 2006, 45 patients (median age 73 (range 53-85) years) underwent primary (41) or secondary (four) F-EVAR for an abdominal aortic with infrarenal neck anatomy unsuitable a standard stent-graft. Median diameter 68 55-100) mm median length 6 0-13) mm. Customized Zenith stent-grafts were employed in all procedures, incorporating fenestrations to preserve flow into renal (80), superior...

Fenestrated endovascular aneurysm repair (FEVAR) is increasingly being used for juxtarenal aortic aneurysms. The aim of this study was to review long-term results and assess the importance changing stent-graft design on outcomes.This a retrospective all patients who underwent FEVAR within single unit over 12 years (February 2003 December 2015). Kaplan-Meier analysis survival, freedom from target vessel loss, expansion, graft-related endoleak secondary intervention performed. Comparison...

To compare unenhanced and enhanced ultrasound imaging to biphasic computed tomography (CT) in the detection of endoleak after endovascular abdominal aortic aneurysm (AAA) repair.Fifty-three patients (44 men; mean age 70 years) were examined during 96 follow-up visits AAA repair. All had color Doppler power studies performed before administration an contrast agent. Biphasic (arterial delayed) CT was on same day, independently scored record presence or absence level confidence observation.The...

To determine whether the introduction of a policy adjunctive stent insertion based on preoperative CT assessment or completion angiography reduced incidence limb occlusion after stent-graft implantation for endovascular aneurysm repair (EVAR).A tertiary referral unit's database was retrospectively interrogated to compare endograft in Zenith grafts following selective insertion. Group A included 288 limbs at risk 146 patients (134 men; mean age 74+/-8 years) treated prior August 2005 whom...

Ligation and bypass is standard treatment for popliteal aneurysm. This technique does not abolish collateral circulation to the aneurysm, which may continue expand and/or rupture. study assessed whether complete thrombosis of aneurysm sac occurs after operation examined long-term clinical outcome.The records all patients who underwent repair in a university hospital over 10 years were reviewed. Patients had undergone ligation recalled ultrasonographic examination determine fate...

Purpose: To report the successful treatment of a carotid artery pseudoaneurysm by percutaneous thrombin injection. Case Report: A 71-year-old man with end-stage renal failure presented acute left ventricular failure. The right common (CCA) was punctured during attempted jugular line insertion, and he developed large connected to CCA long, narrow neck. Ultrasound-guided compression unsuccessful, so another technique attempted. An occlusion balloon inflated in at neck aneurysm avoid distal...
