[Importance of transvenous digital subtraction angiography (DSA) in detecting vascular complications following aorto-iliac/femoral bifurcation bypass]. / Bedeutung der transvenösen digitalen Subtraktionsangiographie (DSA) zum Nachweis vaskulärer Komplikationen nach aortoiliakalem/-femoralem Bifurkationsbypass.

ABSTRACT

From 1970 to 1984 late complications including the prox. anastomosis of aortoiliacal/-femoral bifurcation-prothesis were observed angiographically in 37/647 (6.5%) of patients with art. occl. disease and 4/367 (1.1%) of patients with aneurysmatic disease. Concerning the dist. bilateral anastomotic region the complication-rate was markedly higher. This study was carried out to evaluate accuracy of transvenous DSA in a preselected outpatient group (n = 24) following aortoiliacal/-femoral bifurcation-bypass. In 15 cases DSA showed prothetic complications such as occlusion (n = 4), stenosis (n = 2), anastomotic aneurysms (n = 8) and a.v. fistula (n = 1). The results demonstrate that in outpatients transvenous DSA is a method of low risk to get excellent images of bifurcation-prothesis and prothetic complications considering recommended technical criteria.
