Persistent Sciatic Artery: Case Report, Anatomy, and Review of the Literature

Endovascular Management of Rare Sciatic Artery Aneurysm

“…If the axial artery fails to regress or if there is incomplete development of the femoral arterial system, then the axial artery may persist as a sciatic artery and function as the main supply to the lower limb. 2,4,5,7 Remnants of the axial artery do persist in adult life as parts of the anterior and superior gluteal arteries, as well as the popliteal and peroneal arteries.…”

“…[4][5][6][7][8] Variations in anatomy and pathology are common and present important management considerations. We report endovascular treatment of a complete persistent sciatic artery aneurysm (PSAA) without the need for concomitant revascularization and provide a brief …”

Persistent Sciatic Artery. Case Report

“…It and its aneurysms have been discovered incidentally during angiography, apart from anatomic descriptions of cadaver dissection (Cowie et al, 1960, Joffe, 1964, Wirght, 1964 Noblet et al, 1988). The incidence of sciatic artery found on angiography is estimated to be approximately 0.025% to 0.06% (Mayschak andFlye, 1984, Zaccaria et al, 1986).…”

“…The incidence of sciatic artery found on angiography is estimated to be approximately 0.025% to 0.06% (Mayschak andFlye, 1984, Zaccaria et al, 1986). A recent review of the world literature (Noblet et al , 1988) reports a total of 71 cases of the sciatic artery. Twelve anatomic descriptions of the anomaly in Japanese cadavers have been reported so far (Adachi, 1928, Yamada et al, 1965, Emura et al, 1991.…”

“…The sciatic artery has been associated with various pathologic entities: "crooked leg," hemihypertrophy of the pelvis and leg, short leg, atherosclerosis, obstruction, and aneurysm (Bower et al, 1977). The incidence of aneurysm of the sciatic artery is quite high, having been estimated to be 14% to 35% (Bower et al, 1977, Noblet et al, 1988. The reported aneurysms have been located under the gluteus maximus at the level of the greater trochanter.…”
