Case ReportCoil Embolization of Symptomatic Persistent Sciatic Artery Aneurysm: A Case Report

Case Report
An 89-year-old woman presented to our hospital, complaining of severe rest pain, coldness, and numbness in the right lower extremity with sharp onset 3 days previously. She had recognized intermittent claudication before. Her past history was unremarkable for risk factors of atherosclerosis. Physical examination showed cyanosis in the right lower extremity without apparent tissue necrosis. The right femoral and popliteal pulses were palpable. The pulses below the knee were absent and not
Discussion
In the early embryo, the axial artery is the major vascular supply to the lower extremity.7, 8 In normal development, the axial artery involutes. The femoral artery system develops further and takes the place of the axial artery after the 22 mm embryological stage. The remnants of the axial artery are normally found in the adult as the inferior gluteal artery, the ramus concomitans of the sciatic nerve, the perforating arteries of the deep femoral system, and parts of the popliteal and peroneal

2016, Journal of Vascular Surgery Cases and Innovative TechniquesCitation Excerpt :Treatment of symptomatic PSA aneurysms is to prevent rupture or thrombosis. Endovascular exclusion has been achieved using Amplatzer plugs,5-7 stent grafts,8-14 and coiling.15,16 Open aneurysmorrhaphy and excision with interposition grafting have also been described.1
Bypass Graft Failure Resulting from Misidentification of the Aberrant Anatomy of a Persistent Sciatic Artery
2015, Annals of Vascular SurgeryCitation Excerpt :During the 6-mm stage of embryonic development, the principal arterial blood supply of the developing lower limb is by the sciatic artery, a branch of the umbilical artery. In the 22-mm embryo, the femoral system develops from the external iliac artery and takes over as the primary blood supply to the lower limb.1,2 Once the femoral system is fully developed, the sciatic artery involutes.

2011, Annals of Vascular SurgeryCitation Excerpt :For critical LLI, major amputation was performed in two (10.5%) and six (24.0%) limbs in the LLI and LLI + PSAA limb groups, respectively. The indications of major amputation included inflammatory small vessel disease caused by Buerger's disease,7 thromboembolism from mural thrombus of PSAAs,8,9 and progressive deterioration of distal perfusion.10,11 No surgical or interventional procedures were performed in two limbs (10.5%), three limbs (14.3%), and two limbs (8.0%) in the LLI, PSAA, and LLI + PSAA limb groups, respectively.

2009, Journal of Vascular SurgeryCitation Excerpt :Use of stent grafts for repair of PSA aneurysms have been reported and offer the advantage of a single endovascular intervention, but the anatomic location of these lesions and their propensity for compression and trauma may put these grafts at high risk for complications such as fracture, migration, or occlusion.3,4 Cases of successful aneurysm embolization using pushable coils have been reported.5-7 However, coils are hindered by difficulty with accurate placement and the possibility of unintended embolization of proximal or distal vessels.
