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

Abstract

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.

Successful retrieval of a foreign body in an infant's right pulmonary artery using the new boomerang loop–snare technique: A case report

“…However, this method was not considered because of the possible risk of vascular injury during the procedure. The final strategy involves the lateral grasp technique using a 7 Fr sheath [10] , in which the wire end is grasped outside the guiding sheath using a snare catheter. We considered that it is easier to grasp the end of the microguidewire using a microsnare catheter within the thin guiding catheter than in the thick pulmonary artery.…”
