Case Report (n=1)
A stepwise approach using a pigtail catheter to free the end followed by a gooseneck snare is an effective technique for retrieving dislodged central venous catheters stuck in the pulmonary artery.
Single-case success retrieving peripherally stuck catheter; leaves open generalizability and safety in larger cohorts.
Recent advances in anticancer chemotherapy have resulted in an increase in the number of patients requiring a central venous port catheter, and the incidence of catheter pinch-off syndrome has been increasing. Catheter pinch-off syndrome is a rare and unusual complication. It is difficult to retrieve dislodged catheters from the pulmonary artery, especially if the catheter is stuck to the peripheral pulmonary artery. We herein describe the successful removal of a catheter stuck in the pulmonary artery with a stepwise approach. First, a pigtail catheter was used to tug the dislodged catheter in order to free the unilateral end. Then, a gooseneck snare was used to catch and pull the catheter out of the patient. The key to success is to free the end of the catheter.

Nakabayashi et al. (2016) conducted a case report in Catheter pinch-off syndrome (n=1). Stepwise retrieval approach using a pigtail catheter and gooseneck snare was evaluated on Successful catheter retrieval. A stepwise approach using a pigtail catheter to free the unilateral end followed by a gooseneck snare successfully retrieved a dismembered central venous catheter stuck in the pulmonary artery.
