Superior Vena Cava Thrombosis in A Young Hemodialysis Patient After 1 year of Central Venous Catheter Removal: A Case Report

Abstract

Introduction: Superior vena cava (SVC) syndrome is a rare but serious condition resulting from obstruction of the superior vena cava or its tributaries. Although often associated with malignancy, it can also occur due to central venous catheterization(1). Acute SVC syndrome following catheter removal is uncommon. Case Report: We present a 35-year-old hemodialysis patient with a history of central venous catheterization for hemodialysis one year prior. During a routine hemodialysis session, the patient developed symptoms of shortness of breath, neck swelling, and cyanosis of the lips. Physical examination revealed neck edema and prominent superficial vascular bifurcations. Without imaging studies, it was confused with cellulitis, but CT angiography later confirmed SVC thrombosis. The patient was started on anticoagulation and transferred to a tertiary hospital for further management. Conclusion: Emergency physicians should be aware of SVC syndrome, especially in hemodialysis patients with a history of central venous catheterization. Although it is often associated with malignancy, this case highlights the importance of considering SVC thrombosis even after catheter removal. Prompt diagnosis and appropriate management are essential to prevent life-threatening complications. Therefore, recognition and inclusion of SVC syndrome in the differential diagnosis is essential for timely intervention and improved patient outcomes.
