RESULTS OF VASCULAR RECONSTRUCTIONS AFTER PTA

From 1986 through 1994 263 patients underwent vascular treatment due t o 266 PTA complications. Complications at the site of the puncture wer e found in 35 patients (13.2%), at the site of dilatation in 210 (78.9 %), and due to macro-embolism in 21 (7.9%). The most frequent patholog y wasthrombosis in 135 patients (50.7%). 62% of all operations were pe rformed immediately or few days after PTA. The primary (secondary) pat ency rate after one month in AK femoropopliteal reconstructions was 84 % (88%), in BK reconstruction 69% (74%), after aorto-iliac reconstruct ion 90% (96.8%), in renal artery reconstructions 96% (96%), and in sur gical interventions in the innominate artery and the subclavian artery 100%. In our opinion the unfavourable early results, especially after BK femoro-popliteal reconstructions, are due to a deterioration of th e run-off caused by peripheral microembolisation. Of the aorto-iliac a nd limb artery reconstructions 7.1% required major amputation. The sec ond most frequent complications were wound infections in 6.5%.
