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

Figure 2

Schematic diagram of splanchnic vascular connections using electric circuit symbols. (a) The spatial relations and differences in resistance are ignored. (b) The final basic configuration of connections was simplified using the circuit theory. Note that the stenosis and the aneurysm are represented by potentiometers. CA: celiac artery; SMA: superior mesenteric artery; IMA: inferior mesenteric artery; PHA: proper hepatic artery; PDA: pancreaticoduodenal artery; AoR: arc of Riolan; IVC: inferior vena cava; HV: hepatic vein; PV: portal vein; SMV: superior mesenteric vein; IMV: inferior mesenteric vein.
