Long-Term Results of Thrombectomy with Temporary Arteriovenous Fistula for Ileofemoral Venous Thrombosis

Abstract

Nineteen patients with acute ileofemoral venous thrombosis were subjected to thrombectomy with the addition of a temporary a-v fistula and anticoagulant treatment. At follow-up 3 years after surgery isotope phlebography disclosed more-or-less patent ileofemoral segments in 16 patients. The venous outflow capacity as estimated from venous emptying curves was normal in all but three totally occluded limbs, indicating an adequate collateral compensation. Foot volumetry demonstrated signs of venous valvular insufficiency, mainly in legs with a distal extension of the initial thrombosis; these patients complained of symptoms of post-thrombotic syndrome, which emphasizes the importance of early operation.
