Vessels regularly found during inguinal hernia repairs are the superficial circumflex iliac, superficial epigastric, and external pudendal arteries, which arise from the proximal femoral artery and course superiorly. The inferior epigastric artery and vein run medially and cephalad in the preperitoneal fat near the caudad margin of the internal inguinal ring.

The external iliac vessels pass posterior to the inguinal ligament and iliopubic tract and anterior to the pectineal ligament to enter the femoral sheath. The external spermatic artery arises from the inferior epigastric artery just caudad to the internal inguinal ring to supply the cremaster muscle.
