[A case of percutaneous removal of a catheter fragment from the pulmonary artery using a long sheath].

A case of successful removal of a catheter fragment from the pulmonary artery is reported. We employed the loop snare designed for transcolonoscopic polypectomy through a 9F long sheath. The sheath was advanced into the pulmonary artery over the balloon catheter. Handling of the loop snare was smooth and safe because of there being enough inner diameter of the sheath. Other instruments such as grasping-forceps or basket stone-catcher were also able to be advanced through the sheath. We recommend the employment of the 9F long sheath for retrieval of intravenous foreign bodies.
