350 veins were seen in 117 CT scans. The mean number of pancreatic veins visible per patient was 2.99 with a standard deviation of 1.00. 285 veins were best seen in the portal phase, 14 in the arterial phase, 41 in the venous phase, & 10 with a combination of arterial & portal phase. 172 veins drained the pancreatic head, 69 the body & 109 the tail. The pancreatic head drained into the portal vein (70) or SMV (90). The tail drained primarily into the splenic vein (95) while the body had more variable drainage with 15 veins draining into the portal, 12 into the SMV & 38 into the splenic vein. 10 of 22 patients with pancreatic tumors had veins draining tumors.
293 veins were between 2 & 6 mm in diameter at the origin (83.7%) Of those, 208 were at least 10mm long (59.4%). 118, 32, & 58 drained the head, body & tail respectively. 119 veins were at least 20 mm long (34%). Mean number of pancreatic veins longer than 20 mm visible per patient was 1.42 with a standard deviation of 0.56. 92 veins were seen in the portal, 6 in the arterial, & 18 in the venous phase. 85 veins drained the pancreatic head, 16 the body & 18 the tail. Mean lengths were 34.47 mm, 23.44 mm & 29.52 mm from the head, body & tail.
Conclusion: Based on CT findings, vein diameter and angle are consistent with the ability to canulate the veins from portal access. 83.7% of veins had adequate diameters & 59.4% were of at least 10mm length.
