Treatment of peripheral arterial pseudoaneurysms: a report of 29 cases
Objective: To investigate the effective management for different types of peripheral arterial pseudoaneurysms (PSA). Methods: The clinical data of 29 patients with peripheral arterial PSA treated from March 2011 to December 2015 were analyzed retrospectively. Among 11 patients with femoral PSA, 9 cases underwent aneurysm resection and artery ligation and 2 cases were treated by arterial bypass. Four patients with brachial PSA and 2 patients with radial PSA underwent aneurysm resection and aneurysmorrhaphy, 10 patients, that included 2 cases with posterior tibial PSA, 2 cases with spleenic PSA, 3 cases with internal iliac PSA, one case with mesenteric PSA, and 2 cases with external carotid PSA, underwent coil embolization, and 2 patients with external iliac PSA underwent covered stent placement. Results: After operation, the lumen of PSA in all patients was completely occluded. One patient with femoral PSA developed limb ischemia and necrosis, and then was subjected to second stage amputation, and one patient with infectious external carotid PSA died of hemoptysis. Satisfactory results were achieved in all of the other patients. Conclusion: According to the causes and locations of peripheral arterial PSA, appropriate selection of treatment method may be important for satisfactory results.
