MODEL RELEASED. Implanted venous access port (portacath) visible under the skin of the chest in a patient with haemophilia. The port has a septum through which drugs can be injected and blood samples can be drawn many times. A catheter connects the port to a vein. This kind of port is used to administer drugs and fluids in certain patients, in this case a factor VIII blood clotting agent to treat haemophilia. Such ports are sometimes used to deliver chemotherapy, and for lengthy or frequent delivery of antibiotics in some patients, such as those with cystic fibrosis.
Model release available. Property release not required.
