Abstract
Objective: A post-catheterization femoral artery pseudoaneurysm is a rare but troublesome complication following percutaneous cannulation of the femoral artery. Here, we present three cases of a femoral artery pseudoaneurysm that developed following percutaneous intervention.
Case Presentations: Case 1: An 83-year-old woman received intravenous administration of recombinant tissue plasminogen activator, following which she underwent mechanical thrombectomy for acute ischemic stroke. However, 4 days after the catheterization, she developed a femoral artery pseudoaneurysm at the puncture site. The pseudoaneurysm was successfully thrombosed using ultrasound-guided compression (UGC). Case 2: An 83-year-old woman underwent coil embolization for an intracarotid artery aneurysm and developed a femoral artery pseudoaneurysm on the following day. The pseudoaneurysm was surgically repaired after UGC failure. Case 3: A 72-year-old woman with diabetes underwent transarterial embolization for a tentorial arteriovenous fistula. However, 16 days after the embolization, she developed an infected femoral pseudoaneurysm at the puncture site and was successfully treated using surgical repair.
Conclusion: We reported three cases of a post-catheterization femoral artery pseudoaneurysm that was successfully treated using UGC or surgical repair. Most femoral pseudoaneurysms can be successfully treated less invasively using UGC, ultrasound-guided thrombin injection, and para-aneurysmal saline injection. However, in certain cases, such as an infected femoral pseudoaneurysm, open surgical repair is necessary.
