[Systemic lysis in subacute arterial occlusion].

The therapeutic regimen used consisted of an ultrahigh streptokinase dosage scheme with an infusion rate of 1.5 million units per hour over a period of 6 hours. Where no immediate clearance occurred or where residual stenoses persisted, a catheter dilation (PTA) was subsequently carried out. Favorable results were achieved in the group of up to 6 week old femoral occlusions with 2 or 3 calf arteries open and an occlusion length below 15 cm. Iliac occlusions responded well to lytic treatment if a 3 month history was not exceeded.
