AbstractBackground and Objective: Although extracorporeal membrane oxygenation (ECMO) is an essential life-saving technique for patients with refractory cardiopulmonary shock, it can be fatal in certain cases. Case Presentation: A 19-year-old girl treated with ECMO presented with acute limb ischemia 2 days after cannula removal. The decannulation was performed percutaneously by an interventional cardiologist, and the vascular surgery department was consulted after the patient developed symptoms. The first suspected diagnosis was thrombosis due to incorrect use of the closure device. However, the artery had ruptured due to the insertion of a catheter with a cannula that was larger than the patient's artery. Management and Outcome: Fortunately, excessive bleeding due to the size-mismatched cannula was prevented by an unintentional complication of the closing device, which saved the patient's life. She underwent a right common femoral artery thrombectomy and patch angioplasty. Hospital guidelines have changed regarding the surgical removal of ECMO cannulas. Discussion: This report aims to highlight the importance of two aspects that are critical to a successful outcome: individualized cannula selection followed by precise insertion and removal and postoperative evaluation of a patient's final status.
