vessels for infusion using fixed catheter tip method and gastroduodenal
artery. In modified method, inside lumen of catheter tip is left open and
gastroduodenal artery or right gastroepiploic artery beyond tip of indwelling
catheter is embolized with one or two microcoils (long straight
arrow). Note that point where narrowing of lumen begins is positioned in
aorta (curved arrow). Side hole (arrowhead) is created in
2.7-French diameter, 20-cm-long distal shaft. Diameter of implanted catheter
positioned in common hepatic artery and celiac artery is exclusively 2.7
French (short straight arrows).
