Total occlusion of iliac arteries: Results of balloon angioplasty

摘要: Fifty-six occluded iliac arteries (mean length 6.1 cm; range 1–17 cm) in 50 patients were treated by percutaneous transluminal angioplasty (PTA) or laser-assisted PTA (bilateral lesions 6 patients). Twenty-seven (54%) at high risk for surgery. Patients followed a maximum period of 72 months 23.12 months; median 20 months). The initial success rate was 78.5% and 82% patients. Laser-assisted attempted 11 (19.64%) successful 4 (7.14%). Conventional 71.4% including all 7 which failed (76% unsuccessful 12 (21.43%). Urokinase used before I artery. effect evident clinically relief rest pain (66.66%), healing ulcer (57%), increased claudication distance no (79%) limbs, objectively, improvement ankle/arm index (AAI) (an increase 0.16 to 0.91) exercise tolerance. Continuous AAI observed after on follow-up 9 limbs. One patient died during follow-up. On follow-up, 3 occluded, showed evidence stenosis, 1 fusiform dilatation the site. long-term results using life-table method determined 76% primary patency 81% secondary months. overall failures 63%. Age (p=0.0169) hypertension (p=0.0015) significantly affected artery but not success. major complications arterial rupture repeat procedure artery, axillary thrombosis 1, distal thromboembolic occlusion 4, rates suggest that totally is safe effective provides benefit.
