Central venous septic thrombophlebitis--the role of medical therapy.

Suppurative thrombosis of a central vein is a serious complication of central venous catheter use. Surgical removal of the vein, the treatment usually recommended for peripheral vein suppuration, is technically difficult. We describe six patients with central venous septic thrombophlebitis. Four patients were receiving TPN; three from this group were successfully treated medically with removal of the catheter, intravenous antibiotics, and anticoagulants. The fourth patient improved clinically with 2 weeks of medical therapy prior to surgery, which showed the clot to be sterile. In contrast, two patients with suppuration adjacent to and secondarily involving a large vein required surgical drainage of the perivenous collection. Patients with central venous septic thrombophlebitis can be successfully managed with prompt catheter removal, intravenous antibiotics, and anticoagulation, but surgery should be considered when there is a suppurative focus around the vein.
