2024年9月23日 · A persistent sciatic artery is a rare vascular anomaly where there is the persistence of the embryological axial limb artery, representing a continuation of the internal iliac artery into the thigh through the greater sciatic foramen below the piriformis muscle and down the thigh alongside the sciatic nerve. In normal embryologic development of ...

Persistent sciatic artery (PSA) is a very uncommon congenital malformation. Its incidence is estimated to be 0.025-0.04%. If it is accompanied by hypoplasia of the femoral artery system, its presence is essential for perfusion of the limbs. The usual …

2009年5月1日 · A persistent sciatic artery (PSA) is a rare vascular anomaly with an estimated incidence of 0.03–0.06%. During early embryonic development, the sciatic artery usually disappears when the superficial femoral artery has developed properly. This study aimed to assess the clinical presentation and outcome of a PSA.

Persistent sciatic artery (PSA) is a rare congenital vascular anomaly. The sciatic artery, which normally regresses to become the inferior gluteal artery during fetal development, persists as a direct branch of the internal iliac artery. We report a ...

Persistent sciatic artery is a rare anomaly of the internal iliac artery during embryogenesis. There is a risk of aneurysmal degeneration in up to 60% of the cases, which may further lead to distal embolization and lower limb ischemia [2].

Purpose: The purpose of this article is to describe the embryologic development and anomalous persistence of the sciatic artery, pathologic changes that may occur in the persistent sciatic artery, and management of complications related to these pathologic changes.

Persistent sciatic artery (PSA) is a rare congenital anomaly of the blood circulation in the lower limb that results from the persistence of an artery that normally regresses within the first 3 months of embryonic development.

Repair of the degenerative aneurysm is critical because it can lead to rupture, thrombosis, distal embolization, and sciatic nerve damage from compression. We report a case of a symptomatic unilateral persistent sciatic artery fusiform aneurysm that was treated using a simultaneous open surgical and endovascular approach.

2017年3月3日 · We report two cases of persistent sciatic artery (PSA) aneurysm with limb ischemia. Physicians who treat peripheral artery disease should be aware that PSA is a very rare congenital malformation of the lower extremities that is potentially hazardous, and that revascularization should be performed when a PSA aneurysm is treated.

Our patient had the complete form of persistent sciatic artery, with a large anomalous vessel that became the popliteal artery and a rudimentary SFA that supplied collateral vessels to the popliteal artery (Fig. 2). Endovascular stenting proved a simple, expeditious, and minimally invasive solution to what would have been a difficult surgical ...
