Introduction: Pseudo aneurysms are false aneurysm where disruption in the arterial wall. The common causes are, iatrogenic (vascular interventions and surgery), trauma, and infections.
Aim: The aim of this study was to analyze the etiology, management, and outcome of patients with Pseudo Aneurysm s of peripheral arteries.
Materials and Methods: This is a retrospective analysis of 30 patients with peripheral artery Pseudo Aneurysm s over 2 years at a tertiary referral center in Southern India, at Institute of Vascular Surgery, Madras Medical College, India.
Results: The most common site involved was femoral artery followed by a superficial femoral and anterior tibial artery. The common etiologies were iatrogenic and penetrating trauma. The most common organism was Staphylococci aureus. Management options included ligation with or without revascularization, debridement with vein patch repair, percutaneous thrombin injection and stent graft placement.
Conclusion: Although repair with distal revascularization is an ideal approach, debridement and simple ligation of Pseudo Aneurysm s is a safer alternative in patients without infection or peripheral vascular disease.
Peripheral pseudo aneurysm; Pseudoaneurysm; Trauma
Pseudo-aneurysm as opposed to true aneurysm, do not consist of the entire arterial wall and are usually contained, organized hematoma with a persistent communication from the artery of origin, which has failed to thrombose .
Peripheral artery pseudo-aneurysm although not common, can affect any artery in the body. Common femoral artery(CFA) pseudoaneurysms are more common, being the most common site for various endovascular interventions . Majority of CFA pseudo-aneurysms is less than 3 centimeters in size and do not warrant any intervention as they undergo thrombosis on their own.
All symptomatic peripheral artery pseudo-aneurysms warrant treatment. Pseudo-aneurysm can present as painful pulsatile mass, can get infected and rupture or can cause distal embolization .
Management options include Open surgical ligation with or without revascularization, percutaneous thrombin injection or use of stent graft/flow divider.
