[The significance of vascular surgery treatment of complications following percutaneous transluminal angioplasty of the lower extremities].

In 147 patients suffering from arterial occlusive disease of the lower extremities 162 PTAs of the iliac, femoral and popliteal arteries were performed. Thirteen complications occurred in 12 patients, while surgical intervention was necessary in seven cases (4.3%). Hematoma at the site of the arterial puncture were the most frequent complications, requiring acute surgical intervention (n = 3). In two patients, acute vascular occlusion after PTA required bypass operation and thrombendarteriectomy, respectively. In one patient, presenting with an iliac stenosis, PTA was performed using a transaxillar approach and was complicated by an axillar hematoma due to the ruptur of the arteria subscapularis. Furthermore, one patient with an extended hematoma of the abdominal wall required surgical intervention. The results presented indicate that PTA of the lower extremities for treatment of arterial occlusive disease is a procedure with low risk. Complications, which require acute operative therapy, can be treated mostly successful by small surgical interventions.
