Abstract
In fourteen patients undergoing surgical revascularization (11 with Hauri's, three with Virag's anastomosis) because of erectile dysfunction, the patency of vascular anastomosis was evaluated and visualized by color-coded-Doppler sonography (CCDS). Results were compared with continuous-wave Doppler (CWD) and clinical data. CCDS proved to be superior to CWD with regard to assessment of flow in the penile vessels and to applicability. Strength and direction of flow can be judged visually. Therefore, the nature of the imaged vessel (artery or vein, deep or dorsal artery) can be differentiated. There is a good correlation of CCDS and CWD in their evaluation of the patency of the anastomosis. CCDS showed higher accuracy in detecting deep cavernosal arteries.
