[Results of vascular surgery reconstructions after PTA]

From 1986 through 1994 263 patients underwent vascular treatment due to 266 PTA complications. Complications at the site of the puncture were 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 pathology was thrombosis in 135 patients (50.7%). 62% of all operations were performed immediately or few days after PTA. The primary (secondary) patency rate after one month in AK femoro-popliteal reconstructions was 84% (88%), in BK reconstruction 69% (74%), after aorto-iliac reconstruction 90% (96.8%), in renal artery reconstructions 96% (96%), and in surgical 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 the run-off caused by peripheral microembolisation. Of the aorto-iliac and limb artery reconstructions 7.1% required major amputation. The second most frequent complications were wound infections in 6.5%.
