Central Venous Port-A Catheterization-induced Superior Vena Cava Syndrome in a Patient with an Adenocarcinoma of the Rectum
並列摘要
The superior vena cava (SVC) syndrome is an emergency and potentially fatal event. Malignancy is the most common etiology of the syndrome and catheter-induced thrombotic SVC syndrome is rare. We report a 45-year-old woman who presented with SVC syndrome induced by a Port-A catheter. She had a history of adenocarcinoma of the rectum with resection of the tumor and had completed adjuvant chemotherapy via a Port-A catheter 7 months previously. Computed tomography of the patient's chest revealed a low-attenuation thrombus around the Port-A catheter in the SVC and left brachiocephalic vein. The clinical symptoms improved gradually after sequential management, including anticoagulant therapy, thrombolytic therapy and removal of the catheter.
