Balloon Assisted Transarterial Therapy for Hepatocellular Carcinoma

use of a balloon catheter for providing balloon occlusion, in addition to the standard microcatheter for drug delivery, both catheters are to be placed in parallel through a single guide catheter. Only one arterial puncture wound is involved. The inflated balloon provides temporary occlusion of all arterial tumor feeders except for the one which is selectively catheterized with a microcatheter for delivery of the therapeutic agent. The therapeutic agent consists of Lipiodol mixed with a chemotherapeutic drug, it is delivered through the microcatheter under fluoroscopic control.
