Endovascular management of central venous catheter induced superior vena cava syndrome.

This case series describes the endovascular management of three patients with catheter-associated superior vena cava (SVC) syndrome. SVC syndrome can result from malignant (60%) or benign (40%) etiologies. The most common causes of benign SVC syndrome are indwelling central venous catheters (CVCs) with 1%-3% and 0.2%-3.3% of patients being affected. In all cases, a mechanical thrombectomy device was used to evacuate the chronic and acute thrombus, followed by a balloon angioplasty and stenting of the SVC. Anterograde flow and rapid symptom resolution was achieved following the procedure. No peri- or postprocedural complications occurred. These cases demonstrate the feasibility of endovascular management of catheter-associated SVC syndrome.
