Vascular Port Complication Leading to Surgery of Pulmonary Artery Branch—A Case Report

Abstract

A vessel port, implanted into the central venous system, is used for long-term intravenous drug administration in oncology patients. Although essential for frequent chemotherapy and other treatments, ports can lead to complications such as infection and thrombosis. This article discusses a rare but serious complication: the displacement of a catheter fragment. A 67-year-old gastric cancer patient, experienced malignant recurrence with jaundice and bile duct infiltration post Roux-Y subtotal gastrectomy and D2 lymphadenectomy. After nine cycles of chemotherapy, a catheter fragment from the venous port detached and lodged in a branch of the pulmonary artery in segment VIII of the right lung. Thoracotomy was performed to remove the foreign body. Our aim is to report on the surgical treatment of a displaced detached catheter and to raise awareness about the potential rare complications associated with the use of vascular ports in patients undergoing chronic oncological treatment. Additionally, we screened the PubMed database for similar surgical treatment reports and compared the collected data. Venous port malfunction or non-specific patient symptoms may indicate rare complications, such as port component detachment, necessitating a multidisciplinary approach for prompt diagnosis and management in oncological patients.
