Figure 14a. Pseudoaneurysm. (a) Color Doppler flow image demonstrates the classic swirling pattern in a large pseudoaneurysm adjacent to a pancreatic transplant. The supplying artery is the donor splenic artery (red) with the splenic vein (blue) adjacent to it. (b) Three-dimensional CT angiogram depicts the pseudoaneurysm. The white curved line is the duodenal stump suture line (arrow). The kidney transplant (K) is located posterior to it, whereas the pancreatic transplant (P) is seen as the faint green structure inferior to the pseudoaneurysm. (Case courtesy of Myron A.
