Abstract
During student dissecting practice, a rare developmental anomaly showing persistent sciatic artery (PSA) was found in the bilateral lower limbs of a 74-year-old Japanese male cadaver. The PSA was a continuation of the internal iliac artery on both sides, did not anastomose with the perforating arteries and ended by anastomosing with the popliteal artery on both sides. The course and distribution of the PSA were relatively consistent with previous reports. In the present case, however, the PSA and inferior gluteal arteries existed simultaneously on both sides, despite the general assumption that the inferior gluteal artery is a remnant of sciatic artery regression.
