[Usefulness of CT arteriography for transcatheter peripancreatic arterial embolization to patients with advanced pancreatic cancer].

We reported previously the clinical benefit of hepatic and splenic arterial infusion chemotherapy (HSAIC) for patients with advanced pancreatic cancer alter transcatheter peripancreatic arterial embolization (TPPAE). TPPAE has two therapeutic purposes: (1) preparation for effective arterial infusion chemotherapy, and (2) transcatheter arterial embolization (TAE) against pancreas head cancer. The present paper describes the advantage of CT arteriography in performing TPPAE for advanced pancreatic cancer. CTA was useful in identifying the arterial blood supply in pancreatic cancer, especially blood vessels branched off from the supramesenteric artery (SMA). Since the anti-tumor effect of TPPAE against pancreas head cancer is dependent mainly on whether the blood supply from SMA could be shut off, it is suggested that CTA is useful to evaluate the embolization effect of TPPAE.
