Analysis and prevention of failure causes of percutaneous implantable port for tumor chemotherapy.

The failure causes of percutaneous implantable port (PIP) for tumor chemotherapy were analyzed and the appropriate preventing measures were put forward. During Feb. 1995 to Feb. 1999, 10 patients with tumor undergoing failure insertion of PIP were retrospectively studied. We placed the PIP in the hepatic artery in 3 patients with liver carcinoma after operation, in the internal iliac artery in 5 patients with colonic or rectal carcinoma after operation and in the left gastric artery in 2 patients with stomach carcinoma after operation. The results showed that in the 10 patients, chemotherapeutic agent effusion around the PIP and local tissue necrosis in 5 cases, infection and abscess formation around the PIP in 3 cases, PIP body rupture in one case and the catheter sliding into the internal iliac artery occurred. It was concluded that taking measures during PIP insertion could prevent the occurrence of complications and is beneficial to the implementation of scheduled chemotherapeutic protocol for the patients.
