The inferior epigastric artery (IEA) is commonly used as a recipient vessel in microsurgical phalloplasty but its use can be associated with abdominal parietal complications (hernia, bulging). To preclude such complications and avoid involvement of the femoral artery, we assessed an external pudendal artery (EPA) as a recipient vessel. We studied the disposition of the external pudendal system and its general anatomy. Then we compared the external diameter of the EPA to that of the first branches of the femoral artery. The most important point was to determine the location of the EPA through a reference line to facilitate a surgical approach. We then illustrated this preliminary study with a clinical case to check the reliability of the identified landmarks. Ten adult cadavers were dissected. The arteries of interest were part of a system consisting of either a common trunk or a duplicated system. The branches of the pudendal system arose from either the femoral artery or the deep femoral artery. On a horizontal reference line passing through the two pubic tubercles, we observed that 83% of EPAs arose between the reference line and 3 cm below it, at the level of a vertical axis centered on the femoral artery. The EPA could be suitable as recipient vessel in phalloplasty owing to its location, size, and ease of dissection. Using it instead of the IEA precludes abdominal parietal complications and reduces scarring in the recipient area.
