[Regional thrombolytic therapy of thrombosis of arteries of the pelvis and lower extremities].

Regional thrombolysis was performed in 62 patients with thrombosis of the aorta and arteries of the pelvis and lower extremities. The thrombolytics used were avelysin (20 patients) and celiase (42 patients). Complete lysis of the thrombi was recorded in 49 cases. After successful thrombolytic therapy balloon angioplasty of the revealed stenoses was carried out in 39 patients. After thrombolysis was completed 15 patients underwent various reconstructive operations which failed to produce an effect in 4 patients and the extremity was amputated. The complications of thrombolysis included hematomas at the site of catheterization of the arteries in 5 patients, distal embolism in 7, and an allergic reaction in one patient. The authors appraise the dependence of thrombolysis efficacy on the level, extent, and duration of the thrombotic occlusion.
