Causal Relationship between Celiac Stenosis and Pancreaticoduodenal Artery Aneurysm: Interpretation by Simulation Using an Electric Circuit

Figure 1

Three-dimensional angiomesenteric computed tomogram of a 37-year-old woman with multiple visceral artery aneurysms (VAAs). (a, b) Preoperative scan showing saccular or fusiform VAAs in the pancreaticoduodenal, dorsal pancreatic, and transverse pancreatic arteries (red arrows). Celiac artery (CA) stenosis with collapsed common hepatic and proximal splenic arteries is visible (yellow arrows). (c, d) On a follow-up scan 66 months after VAA resection and clipping, no recurrence is identified. Note that the collapsed CA branches were reconstituted without the relief of CA stenosis (yellow arrows). K: kidneys; S: spleen.
