Study of Cavernosal Arterial Anatomy Using Color and Power Doppler Sonography: Impact on Hemodynamic Parameter Measurement

Abstract

Cavernosal arterial anatomy is variable and hemodynamic parameters differ at various sites of measurement. Parameters should be measured at a consistent proximal site to obtain a reliable assessment. Variations in vascular anatomy and cavernosal artery pathology should be considered when interpreting color Doppler sonography and before penile vascular surgery.

Sonographic diagnosis of penile Mondor's disease associated with absence of a dorsal penile artery

“…Chiou et al described the asymmetry of dorsal arteries, in which 1 artery is well developed, while the other is small, or even atrophic. 8 In our case, we found on color Doppler examination that the right dorsal penile artery was absent. It is likely that the penile dorsal artery, because of its extensive vascular connections with the cavernous artery, provides a hemodynamic support, which can counterbalance slight disorders of cavernous arteries.…”

Colour Doppler ultrasound hemodynamic characteristics of patients with priapism before and after therapeutic interventions

“…This anatomical variation may be responsible for the maintenance of the blood flow at the proximal penile shaft. 4 We placed penile cavernosa-dorsal (CD) vein shunts in all 11 patients. 5 We then performed 12 postoperative…”

Is Sildenafil Citrate an Alternative Agent in the Evaluation of Penile Vascular System with Color Doppler Ultrasound?

“…During the last several years, the management of the diagnostic modalities for ED has been markedly changed because of improved understanding of the mechanism of penile erection and technology on computing systems and radiologic techniques [11,12]. Recent studies have described measurements of blood flow velocities of cavernosal arteries using CDU during vasoactive agents-induced erection as an accurate method in the interpretation of penile vascular status [10,13].…”
