Iatrogenic False Aneurysms. A Rare Complication of Hip Surgery

Abstract

The purpose of this study was to determine the incidence of arterial false aneurysms following hip surgery diagnosed and treated in our hospital between January 1995 and January 2010. We conducted a retrospective analysis of all patients undergoing hip surgery (osteosynthesis, hemi-arthroplasty, total arthroplasty, or revision arthroplasty) under our care. To determine the incidence of arterial false aneurysm, we identified patients with abnormal bleeding through the surgical wound postoperatively. Out of the 11,839 patients undergoing hip surgery during the study period, 321 had abnormal bleeding that aroused suspicion of an associated vascular lesion. Among these, the presence of a false aneurysm requiring specific treatment was confirmed in eight patients. False aneurysms are a rare and occasionally severe complication of hip surgery that typically manifest with significant haemorrhage during the postoperative period. The management of these lesions by interventional radiology is associated with few complications and permits rapid patient stabilisation and early recovery, avoiding more aggressive and sometimes fruitless surgical exploration.
