title: Evaluation of the vascular supply to regions of the pancreas on CT during arteriography.
abstract: BACKGROUND
  To evaluate the vascular supply of regions of the pancreas on computed tomography (CT) during arteriography with selective catheterization.
  
  
  METHODS
  Thirteen patients were included. In each patient we performed conventional arteriography followed by CT during arteriography of each of the arteries: the superior mesenteric artery (SMA), gastroduodenal artery (GDA), and splenic artery (SPA). The regions of the pancreas that were most enhanced on CT during arteriography were considered to be the areas receiving the greatest infusion of blood from the selected artery.
  
  
  RESULTS
  In all 13 patients, the uncinate process, the superior head, and the tail of the pancreas were predominantly supplied by the SMA, GDA, and SPA, respectively. The inferior head of the pancreas was predominantly supplied by the SMA in five patients, the GDA in nine patients, and both the SMA and GDA in one patient. The body of the pancreas was predominantly supplied by the SMA, GDA, and SPA in seven, two, and ten patients, respectively.
  
  
  CONCLUSIONS
  The uncinate process predominantly infused by the SMA, the superior head by the GDA, and the tail by the SPA. The patterns of the vascular supply of the inferior head and the body vary from patient to patient.
