In order to summarize the experience in the treatment of ischemic necrosis of lower extremities resulted from thrombotic occluded angittis, 15 cases were reported, which were treated by primary arterization in situ of V. Saphena magna. With a period of follow-up, 4-26 months on the average, it was found that symptoms in 14 cases were much allayed obviously, except 1 case with little relief. It suggested that primary arterization in situ of V. saphena magna could improve the circulation of the ischemic extremity rapidly without any influence of venous reflux.
Objective To investigate the effect of arterilization of veins in treatment of extensive arterial oblitery ischemia of limbs . Methods Eighteen lower limbs and six upper limbs with symptoms of chronic ischemia were diagnosed as having extensive occlusion of the major arteries by color Doppler Ultrasonic Scanning and DSA. According to the level of occlusion, the involved limbs were treated by arterilization of veins in one stage. Results During hospitalization, one lower limb was amputated. Seventeen lower limbs and six upper limbs were followed up for 3 to 26 months. Among them, one lower limb was amputated for necrosis of toes after 3 months; the outcomes of the others were satisfactory. By Doppler scanning, the arterial blood flow was observed after operation. Conclusion Arterilization of veins in extensive arterial oblitery ischemia of limbs is a simple and effective treatment with good result.
