Re-evaluation of thrombectomy in the management of iliofemoral venous thrombosis

Abstract

The authors studied 15 patients with iliofemoral venous thrombosis up to 8 years after the diagnosis was made, to determine whether there was late deterioration in venous function following thrombectomy. Twelve patients were treated by venous thrombectomy and anticoagulants and 3 by anticoagulants alone. Eight of the 12 patients subjected to thrombectomy had an excellent result with limbs that were considered normal. This did not confirm earlier reports which indicated that good early results were not maintained. In 4 of the 12 surgically treated patients minor symptoms of leg pain and swelling were present which also did not progress with time. In all patients treated by anticoagulants alone major symptoms of leg pain and severe swelling persisted. Three of the four patients with persistent minor symptoms after venous thrombectomy were found at operation to have left iliac vein compression syndrome. Only one of eight patients having an excellent clinical result had this syndrome.
