A CASE OF ADVENTITIAL CYSTIC DISEASE OF POPLITEAL ARTERY

A REPORT OF THE SECOND CASE AND CONSIDERATIONS ON DIAGNOSIS BY IMAGING EXAMINATIONS

Abstract

This paper describes our second experience of advantitial cystic disease of popliteal artery in a 56-year-old man who could be diangosed preoperatively and successfully treated. This may be 34th case reported in Japan.
The patient suffered from sudden onset of claudication on left lower thigh. The symptoms fluctuated day by day in spite of medical care, and reduced by rest. Accurate preoperative diagnosis was made by characteristic features such as a narrowing popliteal artery and periaterial cystic figures in arteriogram, ultrasonogram and enhanced CT. Cystectomy was carried out and the symptoms disappeared post-operatively.
Preoperative diagnosis of this disease may not be so difficult when one knows well about several characteristics in clinical symptoms and imaging examinations.
