METHOD FOR DRUG PERFUSION TO TUMOR OF PARA-AORTIC LYMPH NODE, SHEATH FOR CATHETERIZATION, INTRODUCER FOR CATHETERIZATION, AND PERFUSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drug perfusion method for treating tumors of para-aortic lymph node, wherein a drug delivered to the tumor tissues is prevented from leaking to peripheral tissues, a high level of the drug can be efficiently exposed to the lymph node, and adverse effects on patients due to the drug can be reduced or prevented.;SOLUTION: In the drug perfusion method, a vascular blockage area is made by blocking a right renal artery 20, a left renal artery 21, a celiac artery 12, a superior mesenteric artery 19, an inferior mesenteric artery 24, an aorta 3 and an inferior vena cava 4 by using balloon catheters 32-1, 32-2, 32-3, 32-4, 32-5, 33 and 34. The drug is administered from an unbranched sheath 40-3 to the vascular blockage area, and the blood containing the drug is drained from an unbranched sheath 40-4. An oxygenated blood is sent from the tips of the balloon catheters 32-1, 32-2, 32-3, 32-4, 32-5 to protect the organs from blood removal, during vascular blockage.;COPYRIGHT: (C)2006,JPO&NCIPI
