Figure 1. a, b
Initial post-TIPS arterial phase coronal CT scan (a) demonstrates small abnormal draining veins in the periphery of the pancreatic head/uncinate (short-dashed line) and the pancreatic tail (long-dashed line). Arterial phase coronal CT scan obtained 8 years later (b) shows replacement of the pancreatic head/uncinate and tail by feeding arteries, hypervascular parenchyma, and early-draining veins. CHA, common hepatic artery; PV, portal vein.
Figure 2. a, b
Figure 2. a, b
Image (a) from superior mesenteric artery (SMA) angiogram demonstrates multiple inferior pancreaticoduodenal branches supplying the component of the AVM within the uncinate process (UP). Rapid filling of the portal vein (PV) is noted, which has been accessed with a guidewire through the existing TIPS. EVOH and coils from the initial (celiac side) embolization are present (arrows). Single spot image (b) shows midline upper abdomen after extensive embolization of the pancreaticoduodenal arcades with EVOH.
