Distal pancreatectomy with en bloc celiac axis resection (DP-CAR) was designed to provide microscopically negative margins of the celiac artery, nerve plexus, and retroperitoneal tissue for patients with locally advanced pancreatic body cancer. We have been routinely performing the preoperative embolization of CHA for those patients scheduled for DP-CAR since August 1998, to limit the post-surgical ischemic complications of the liver, gall bladder and stomach, by maintaining the blood supply through development of collateral pathways via the superior mesenteric artery and pancreatic arcade. When performing preoperative CHA embolization, it is important to preserve the proper hepatic artery and gastroduodenal artery in order to develop the collateral pathways. It is also preferable to preserve a more than 5-mm length of the distal CHA for easier ligation at surgery. We employed several conventional embolization techniques. However, migration of embolic material from CHA occurred in several patients. From these experiences, we developed an embolization technique using two simultaneous microcatheters and interlocking detachable coils (IDCs). We call this a “dual microcatheter-dual IDC (DMDI) technique”. The DMDI technique provided an excellent high success rate than conventional technique. Recently, embolization technique using amplatzer vascular plug4 (AVP4) has become an good alternative to DMDI technique due to its excellent ease of positioning of AVP4.
