Abstract

Patients with chronic iliocaval occlusions after thrombosis often present with exercise intolerance, which improves after venous reconstruction. Three male patients with chronic iliocaval occlusions underwent a cardiorespiratory fitness test before and 2.5–11 months after venous reconstruction using stents. After the intervention, average absolute oxygen consumption increased by 29.5%, maximal oxygen consumption relative to body weight increased by 38.7%, total work at maximum exercise increased by 74.4%, and exercise time increased by 18.7%. The cardiorespiratory fitness test may be a useful noninvasive tool to objectively evaluate exercise intolerance due to chronic venous occlusions and response to therapy.
