title: Peripancreatic arterial anatomy analyzed by 3-dimensional multidetector-row computed tomography.
abstract: OBJECTIVE
  Since the anatomy of the peripancreatic vessel system is complex, it is important to preoperatively clarify the running aspects of such vessels, especially when pancreatoduodenectomy is performed.
  
  
  METHODS
  In 166 patients undergoing multidetector-row computed tomography, peripancreatic vessels were three-dimensionally reconstructed using computer software.
  
  
  RESULTS
  The dorsal pancreatic artery branched from the splenic artery (45.4%), common hepatic artery (24.8%), superior mesenteric artery (SMA, 15.6%), celiac axis (9.9%) and other arteries such as the middle colic artery (4.3%). Branching of the inferior pancreatoduodenal artery (IPDA) was categorized into two types: a single main IPDA branching from one artery, such as the first jejunal artery (J1a, 55.2%) and SMA (25.1%) and two IPDAs branching from one artery (J1a, 7.0% or SMA, 2.8%) or separately from two arteries (3.5%). Most IPDAs (129 of identified 168 IPDAs) ran behind the SMA at the right edge of the SMA. In 52 patients, superior mesenteric vein tributaries ran above the SMA and mask the IPDA's ramification.
  
  
  CONCLUSIONS
  Peripancreatic vessel anatomy is very complex. The preoperative 3D arteriography and portography enables us to obtain precise information about peripancreatic vessels.
