Abstract
Selective internal pudendal angiography was performed in 195 men (average age, 35.4 years .+-. 10.3) who were suspected of having arteriogenic impotence. In the majority of patients, disease was localized to the cavernosal arteries. A previous series that involved older patients had demonstrated significant disease in hypogastric and internal pudendal arteries. When controlled for trauma, the data revealed no significant difference (X2 test, P > .10) in the distribution of hemodynamically significant penile arterial disease. However, in patients who had sustained major pelvic trauma, the common penile artery was frequently hemodynamically compromised. There is a great deal of variation in the origin of the internal pudendal artery. An accessory pudendal artery was demonstrated in 7% of the patients. If a selective internal pudendal artery injection fails to demonstrate the penile arterial anatomy, a loss of selective injection should be performed. Bilateral injections should always be performed, as unilateral arterial disease was present in 15% of the patients.
