“…PSA is prone to develop an aneurysm due to either an inherent collagen defect or hypoplasia of the connective tissue in the primitive arterial wall (2,5). Repeated compression can subsequently result in the development of a PSA aneurysm (PSAA) (6,7). In addition to the pain caused by the aneurysm itself or neuralgia due to compression of the sciatic nerve by the aneurysm, PSAA can also cause ischemic manifestations due to thrombotic occlusion of the lower limb arteries (2)(3)(4)8), thus resulting in the amputation of the lower limb in 18% of such patients (9).…”

An Infected Massive Persistent Sciatic Artery Aneurysm Treated by an Aneurysmal Incision and Drainage after Angiographic Embolization

A man in his 80s undergoing chronic hemodialysis presented with a high fever. A 10-cm soft mass was palpable in his right buttock. Abdominal computed tomography and angiography showed an incomplete-type unilateral persistent sciatic artery aneurysm (PSAA) with gas patterns and a blood flow through the aneurysm. Incision drainage was performed after arterial embolization. Gram staining of the hematoma showed gram-positive cocci that had formed chains, thus leading to a diagnosis of an infected PSAA. Drainage by incision after arterial embolization was used as the therapeutic method of choice for a massive infected PSAA with a sustained blood flow in order to prevent sciatic nerve injury and bleeding associated with PSAA resection.
