南予医誌 Vol.13 No. 1 2012-28-Abstract Outpatient cancer chemotherapy is replacing inpatient care, and central venous catheter (CVC) ports are being used more frequently for the infusion of chemotherapeutic agents. However, this has led to an increase in so-called “pinch-off syndrome” or the breaking of the CVC, a long-term complication of CVC port implantation. We recently experienced two cases of CVC division in our hospital. Case 1: A 65-year-old female received chemo-therapy via an implanted CVC port for advanced colon cancer. When the port was flushed with heparin, she complained of pain and swelling involving her left upper chest. An X-ray revealed that the catheter had ruptured and its distal tip was found in the superior vena cava and right atrium. We retrieved the tip with a loop snare catheter (Gunther Tulip Vena Cava Filter Retrieval Set®) via the right femoral vein. Case 2: A 55-year-old female received outpatient chemotherapy via a CVC port for advanced colon cancer. When the port was flushed with heparin, she also complained of swelling of her left upper chest. Computed tomography revealed that the CVC tip was in the left pulmonary artery. We successfully retrieved the tip with an endovascular snare system (EnSnare®). Non-surgical retrieval of foreign material via an endovascular approach is safe and feasible for managing division of a CVC.
