Endograft (VORTEC) reconstruction of aortic branches allowing endovascular treatment of aortic aneurysm.

Periscopes, chimneys, sandwich and VORTEC to facilitate abdominal and thoracoabdominal aortic aneurysm repair

The VORTEC (VIABAHN open revascularization technique) and the chimney graft technique are tools with which to maintain or restore blood flow to the aortic branches and can be used intentionally or as a bailout procedure in open surgery or endovascular procedures. VORTEC is a stent graft-based vascular connection technique that achieves end-to-end anastomosis configuration; it is especially useful when the traditional suture technique proves (can be) cumbersome. It is also a speedy tool with virtually no blood flow interruption and no anastomotic bleeding, and patency rates compare favorably with sutured anastomosis. The chimney/periscope, as well as the sandwich graft technique (CHIMPES), i…

Akute Gefäßerkrankungen in der Gastroenterologie. Der Gastroenterologe - Acute gastroenterologic vascular diseases

Acute gastroenterologic vascular emergencies are common situations in emergency departments and the clinical consequences range from trivial to life-threatening. Only the early recognition of these symptom patterns and prompt use of the appropriate diagnostic tools lead to a correct diagnosis with subsequent potentially life-saving treatment. To decrease the high mortality rate of acute mesenteric ischemia (50%), aorto-enteric fistula (30–40%), visceral artery aneurysms (10– 100%) and Budd-Chiari syndrome new strategies with an endovascular approach are gaining importance and are partially replacing established diagnostic and therapeutic algorithms. This article provides a review of the dia…
