“…An aneurysm associated with type 2 PSA requires treatment of the aneurysm with simultaneous revascularization of the extremity. 3 The repair of the PSAA with an interposition graft and ligation of the aneurysm with a femoropopliteal bypass have been advocated in such situations. 3 , 4 The long-term outcomes for the former procedure have not been reported beyond 24 months.…”

“… 4 Although not proved, the skepticism associated with direct repair has been related to the difficult access and the possibility of graft thrombosis and aneurysm formation attributed to repeated trauma from sitting on the prosthetic graft. 1 , 2 , 3 The prosthetic conduit of choice should preferably be the ringed PTFE graft because it can withstand the compression and repeated trauma from sitting compared with a plain PTFE graft. An externally supported Dacron graft could be another option; however, the available data on its use are limited, and the incidence of graft complications has seemed to be greater with Dacron grafts.…”

“…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). Furthermore, a previous report has focused on a few cases of a ruptured PSAA with a maximum diameter of !…”

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

et al. 2022

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.

“…PSA is particularly prone to undergo aneurysm formation or atherosclerosis. Some of the other congenital abnormalities associated with the persistence of this vessel are abnormal right subclavian artery, arteriovenous fistulas, Mullerian agenesis, and atypical patterning of varicose veins [ 3 ]. A literature search resulted in one systematic review, which revealed that 48% of cases presented with aneurysm of the PSA [ 4 ].…”

Radiological and Embryological Relevance of Persistent Sciatic Arteries: A Rare Presentation

Persistent sciatic artery (PSA) is an extremely rare condition that is present in around 0.05% of the population and is commonly associated with many complications. The management is conservative or through surgical intervention and depends on the type of complication. The case presented is of a 40-yearold man who complained of persistent pain in the buttock region. On radiology, bilateral PSAs were observed exiting through the infra-pyriformis compartment of the greater sciatic foramen accompanying the sciatic nerve. The femoral artery and the external iliac artery are small in caliber. In this case report, we discuss the underlying embryology that might have led to the persistence of this vessel with illustrations and the abnormal radiological pattern of this anomaly. Increased awareness of PSA can improve patient care and prevent potentially hazardous complications during hip and renal transplant surgery.
