Volume-dependent superior vena cava syndrome related to stenosis after central venous catheterization.

commonly due to thrombosis, represents a common and serious complication of long-term central venous catheterization. Thickening of the vascular intima or thrombosis involving the superior vena cava (SVC), if severe enough, can present clinically as the SVC syndrome. Typically, the symptoms of SVC syndrome, including headaches, brawny edema of the upper extremities, head and neck, and prominent collateral vascularization are present while the patient is euvolemic. As a result, treatment modalities for SVC syndrome focus on restoring patency of the stenotic vessel with early fibrinolysis, thrombolytic therapy, venous angioplasty, expandable metal stenting or surgical thrombectomy. We report a case of SVC syndrome in a hypervolemic patient who was treated by restoring euvolemia with furosemide diuresis.
