Deep vein thrombosis after renal transplantation: a prospective analysis of frequency and risk factors

In a prospective study the frequency of deep vein thrombosis during the first 3 weeks after kidney transplantation has been evaluated using the combination of thermography and strain-gauge plethysmography for objective diagnosis. 83 consecutive patients were included, 33 with juvenile diabetes mellitus. The overall frequency of thrombosis was 24.1%, diabetes mellitus being a significant risk factor. No other risk factors were found. The transplant did not influence the venous outflow from the corresponding leg. Plasminogen activator activity in the iliac vein wall at transplantation did not differ between patients with and without thrombosis.
