Radiopeptide Infusions of Hepatic Metastases After Temporal Implementation of an Intra-arterial Port System

On the course of the intra-arterial PRRT with 111In-DTPA0-Octreotide, often, due to the multiple (approximately 12) consecutive catheterizations, the femoral arteries get hardened; a port system ending at the proper hepatic artery is subcutaneously, temporarily implanted. The implantable port absolves the patients of the repeated discomfort due to the catheterization procedure and the obligatory 24 h-immobilization of the lower limb to avoid a possible hematoma, due to the preceded puncture of the femoral artery that the patient had to undergo for the hepatic artery catheterization. This port system offers stable connection mechanism at port chamber/catheter junction, high flow rate in thin catheters, secure placement of the puncture needle in the chamber septum, easy location of the puncture site, and quality of life. This chapter describes in detail the therapeutic scheme with repeated high doses of 111In-DTPA0-Octreotide, applied by means of this temporary implemented Intra-arterial Port System.
