[The Treatment of Aneurysms of the Extremities Arteries - a Systematic Overview - New Therapies for Isolated Iliac Artery Aneurysm Employing a New Classification]

Aneurysms of arteries in the extremities have a low incidence and are often manifest through complications. The most serious complications are rupture and extremity-threatening ischemia. Both usually lead to the diagnosis. Absolute indications for therapy are symptomatic aneurysms and asymptomatic aneurysms of 2 cm diameter or more. The extrailiacal gold standard is interponat or bypass with venous graft material. Endovascular methods are reserved for inoperable patients and clinical decisions on special cases. In contrast, complex endovascular techniques have been established in isolated iliac aneurysms and have significantly improved treatment options. Their implementation is bound to the existence of a suitable landing zone. This is the basis for a new classification of isolated iliac artery aneurysm. With the help of morphological subtypes, this classification permits standardised procedure planning for perfusion preservation of the internal iliac artery. The present article gives an overview of the current treatment strategy for aneurysms of extremities arteries. Similarities and regional differences in therapy are discussed.
