Percutaneous Retrieval of a Misinserted Pigtail Catheter Straightener during Infra-Renal Abdominal Aortic Stenting: A Case Report.

Percutaneous retrieval of an intravascular foreign body is a minimally invasive technique. Using cone-beam computed tomography and the lateral grasp technique, we successfully retrieved a pigtail catheter straightener that had been misinserted into the right common iliac artery. Some examples of catheter straightener retrieval have been reported; however, it is important to take care not to accidentally insert a catheter straightener into a vessel via an angiographic sheath.
