Chemoport Fracture due to Catheter Pinch Off Syndrome: A Rare Complication of Subclavian Vein Approach Revisited.

Chemoports are routinely used for administering chemotherapeutic agents, drugs, blood, and blood products. Chemoport insertion is associated with inherent complications. Fracture of chemoport due to pinch off syndrome is a rare life-threatening complication. We report our experience of fracture chemoport in patients with carcinoma breast and its management. We also present a detailed review of literature about this complication, clinical features, warning signs, diagnostic workup, management, and prevention. From a prospectively maintained database of chemoport insertion patients, a retrospective analysis was done from 2017 to 2020. During this period, the incidence of fracture chemoport was evaluated and their management. Out of 560 chemoport insertions, there were 3 patients with chemoport fracture, with an incidence of 0.5%. All the three patients were hemodynamically stable, with no clinical signs of pulmonary embolism. The chemoports were non-functional and on radiologic evaluation fracture of chemoport with embolization of distal segment was demonstrated. All the patients were managed by retrieval of the embolized catheters by a snare and removal of port chambers under local anesthesia. Choose internal jugular vein over subclavian vein for placing central venous access devices. When subclavian vein is chosen, point of entry should be lateral part of costochondral space. The incidence of chemoport fractures is 0.5% which present as non-functioning chemoports. Identify pinch off sign, especially with an upright check X-ray after chemoport placement. Consider repositioning of chemoport if pinch off sign is present.

"Difficult to flush chemoport: an important clinical sign".

A central venous access device is an intravenous device whose internal tip lies in a large central vein. Chemoport is a central venous device which serves various purposes in oncology practice apart from optimum delivery of chemotherapy. Various early and late complications have been frequently reported with the use of these devices. Fracture-embolization of the port catheter is an uncommon but life-threatening complication. Timely recognition and management is important to minimize the morbidity and mortality.

Two Cases of Fractured and Embolized Implanted Central Venous Chemoports in Lung Cancer / 결핵및호흡기질환

Totally implanted central venous access devices for chemotherapy (chemoport) are being used increasingly in lung cancer patients. Vascular catheters are associated with various complications including infection, thrombosis as well as spontaneous fractures and embolization of the catheter, which is known as 'pinch-off syndrome'. 'Pinch-off syndrome' refers to the compression of a subclavian central venous catheter between the clavicle and first rib resulting in an intermittent or permanent obstruction, which can lead to tears, transection, or embolization. We report two cases of fractured and embolized implanted subclavian venous catheters in which the fragments were removed percutaneously. A 62-year-old man presented with back pain with a duration of a few weeks. The chest radiograph revealed complete transsection and embolization of the catheter into the right atrium. In addition, a 47-year-old woman with a chemoport had a grade 3 pinch-off sign in a chest radiograph demonstrating complete transsection and embolization of the catheter into the pulmonary artery. Both cases were managed by retrieving the embolized distal fragment percutaneously and removing the proximal section of the catheter.
