171 chronic arterial occlusions and 86 acute venous thromboses were treated by systemic ultrahigh streptokinase (UHSK) infusions. 38% of the patients were over 65, 27% over 70 years of age. The UHSK scheme consisted of a 1.5 million units SK per hour maintenance infusion over a period of 6 hours. 46% of the patients received one, 47% two, 6% three, and 1% four series (one series per day). 81% of the arterial patients had a history of less than 3 months. In 54% of the cases PTA followed UHSK treatment for dilation of a residual stenosis or removal of occlusion residues still persistent. In the venous patients the most proximal location was distributed as follows: calf veins 1%, femoral vein 57%, iliac vein 28%, subclavian vein 14%. The average thrombosis history was 8 days.
Clearance rates of chronic arterial occlusions
By setting up of sub-groups more favorable results were calculated. For exemple, a femoral occlusion group consisting of cases with a history shorter than 6 weeks and 2 or 3 calf arteries patent displayed a clearance rate of 77%, a figure much higher than the overall femoral result
Clearance rates of deep venous thrombosis
The thrombosis duration played a significant role for thrombosis dissolution. The average occlusion history was 6 days in the total clearance group compared with 12 days in the unsuccessful cohort.
