[Cockett syndrome. Initial results with percutaneous treatment in 6 patients].

Intimal hypertrophy with venous spur formation caused by compression of the left common iliac vein by the right common iliac artery is advanced as the etiology of the higher incidence of deep venous thrombosis involving the left leg. In most cases of left iliofemoral thrombosis no underlying compression syndrome is detected or treated because the left common iliac vein has to be cleared from thrombi before compression can be identified. A series of 6 consecutive retrospectively analyzed patients with acute left iliofemoral thrombosis is presented. In these patients a left iliac vein compression syndrome was detected after percutaneous intraluminal thrombolysis with Actilyse (rt-PA). This compression was successfully relieved by insertion of a wall stent. Percutaneous treatment of Cockett's syndrome seems an attractive alternative for conservative and/or surgical management.
