Abstract

Catheter obstruction is a venous access port related complication occurring when infusion and withdrawal of blood from the system are not possible and is caused by the formation of a blood clot or other substances precipitation. Frequent infusion through the catheter of solutions containing heparin and positive-pressure locking techniques reduce occlusion incidence. A correct management of a suspected occlusion requires a chest radiograph to verify the correct positioning of the catheter and a Doppler Ultrasound or venography to evaluate the possibility of vascular thrombosis. Catheter obstruction is usually successfully treated by infusion of a fibrinolytic agent.
