Infected Massive Thrombosed Persistent Sciatic Artery Aneurysm Treated by Small Incision Drainage: A Case Report.

Extensive debridement requires a large muscle incision and carries with it a risk of sciatic nerve injury. However, a thrombosed aneurysm has little risk of haemorrhage. Therefore, drainage and removal of the thrombus via a small incision, which is less invasive, was considered effective for this infected thrombosed PSAA.
