RODRIGUES, Tiago André Moura et al. Bilateral persistent sciatic artery: a case report of a rare variant with clinical implications. Angiol Cir Vasc [online]. 2017, vol.13, n.3, pp.56-58. ISSN 1646-706X.

Although rare, the persistence of a sciatic artery is a clinically significant vascular variant, since it is often associated with complications such as aneurysm formation, thrombosis and ischaemia. We present the case of a patient with signs of subacute ischaemia on the right lower limb and a pulsatile mass in the right inferior gluteal region. CT angiography revealed a bilateral persistent sciatic artery (PSA) complicated by aneurysm formation and embolization of distal popli­teal artery. Treatment included a femoro-popliteal bypass, ligation of the popliteal artery above the anastomosis and embolization of the aneurysmal lesion.

Keywords : Persistent sciatic artery; anatomic variants; aneurysm; lower extremity; CT-Angiography.
