Diagnosis and treatment of Leriche syndrome: a report of 33 cases / 中国普通外科杂志

ABSTRACT

Objective To summarize the diagnosis and treatment of 33 cases of Leriche syndrome. Methods A retrospective review of the clinical data of 33 cases of Leriche syndrome was done. Results Claudication and impotence occurred in 79.9% and 70.4% of the cases. Color Doppler ultrasonography, especially combining with CTA or MRA, was helpful for the diagnosis. Aortic angiography or DSA was necessary for the determination of the clinical patterns and selecting the therapeutic methods. Surgical patterns selestion should be considering the patients' general status and conditions of the affected vessels. Surgical treatment was performed on 25 cases, including12 aortoiliac artery bypasses , 6 aortobifemoral artery bypasses , 4 axillo bifemoral artery bypasses, 2 embolectomies by Fogarty tube only and 1 aortal interposition with artificial vessel plus renal artery plasty. Aorta iliac artery bypasses get the best results with 1 year patency rate(100%) in all cases, and 5 year patency rate of 75.0%, which was significantly superior to those axillo bifemoral artery bypass grafts with 5 year patency rate of 37.5%. All the other 8 patients without operation died within 5 months. Conclusions Early diagnosis and comprehensive therapy should be adopted to improve the long term patency rates of grafts transplantation in Leriche syndrome.
