Postoperative deep venous thrombosis after renal transplantation. Effects of cyclosporine

In this prospective study the frequency of deep venous thrombosis during the first three weeks after renal transplantation was determined using a combination of strain gauge plethysmography and thermography for objective diagnosis. Ninety-seven consecutive patients were studied, 30 patients having juvenile diabetes mellitus. As immunosuppression cyclosporine and low-dose steroids were used. The series was compared with a similar group of 83 patients, 33 having juvenile diabetes mellitus treated with azathioprine and high-dose steroids as immunosuppression, in which the diagnosis of deep venous thrombosis was made with an identical technique. The overall frequency of thrombosis was 9.3% in the cyclosporine-treated group, which is a significant reduction in comparison with the azathioprine group (24.1%). It is concluded that the combination of cyclosporine and low-dose steroids does not increase the frequency of deep venous thrombosis in comparison with azathioprine and high-dose steroids in renal transplanted patients.
