From July 1988 to January 1991 six patients, aged 29 to 70 years underwent transfemoral thrombectomy for the treatment of deep vein thrombosis. Preoperative venograms showed thrombi in the following locations : calf veins(five), superficial femoral or popliteal veins (four), common femoral veins(three), and iliac veins(three), Durations of symptoms before admission were from 1 day to 20days.
Operations were performed under local anesthesia and all the patients were requested for doing Valsalva maneuver during thrombectomies. All patients were received heparin pre-and postoperatively, which was switched to Coumadin for preventing of rethrombosis.
One patient was tranferred to other hospital 4 months after opration due to regional reason, and the remained five patients were evaluated with a mean follow-up time of 20 months. There was no evidence of postoperative pulmonary embolism. Three of five patients were clinically asymptomatic. One complained of the heaviness of involved leg in the evening, and the other had discomfort on walking
Even though our cases were a few in number, we concluded that thrombectomy is a valuable treatment modality of deep vein thrombosis.
