Anatomical variations of the hepatic portal vein associated with incomplete celiac trunk.

An association of two anatomical variations was revealed in a 65-year-old male cadaver: the first variation concerns the forming of the trunk of the hepatic portal vein, while the second concerns the branches of the celiac trunk. In this case, the inferior and superior mesenteric veins form a common trunk that is further united with the splenic vein and gives rise to the hepatic portal vein. At the same time, the existence of an incomplete (branched) celiac trunk was revealed, the hepatosplenic trunk from which the common hepatic artery and the splenic artery arise; the left gastric artery arises separately at 0.

Ectopic kidney with malrotation and bilateral multiple arteries diagnosed using CT angiography.

Right renal ectopia with malrotation was seen on a CT angiography in a 64-year-old male patient. Bilateral triple renal arteries were also revealed: one main (superior) renal artery and two accessory arteries (middle and inferior), all originating in the abdominal aorta. The renal arteries are disposed symmetrically.
