The authors report the case of a 53-year-old male found to have an extremely rare case of a triple anatomical variation highlighted by multidetector computed tomography (MDCT) angiography, with the presence of a hepato-spleno-mesenteric trunk (HSMT) in association with an accessory left hepatic artery (ALHA) and a common trunk origin of right (RIPA) and left (LIPA) inferior phrenic arteries from left gastric artery (LGA) arising independently from the abdominal part of aorta (AA). The HSMT with an endoluminal diameter of 10.9 mm at its origin, and a length of 4 mm arose from the anterior wall of the AA at the level of 1∕2 upper part of the L1 vertebral body. From the distal portion of HSMT, give birth to the hepato-splenic trunk (HST) and to the superior mesenteric artery (SMA). HST, with a diameter at origin of 9.2 mm and 22.3 mm long, has an upward trajectory and done with the anterior face of AA an open angle to the top of 69°. From the distal part of the HST, arise common hepatic artery (CHA) and splenic artery (SA). The LGA, with an endoluminal diameter of 4.2 mm at origin, arose directly from the anterior wall of the AA at the level of the lower 1∕3 of T12 vertebral body, 8.2 mm above the origin of the HSMT. It ran upwards in front of the AA and after 59.5 mm gave rise to an ALHA. At 18.6 mm from its aortic origin, LGA gives birth to an inferior phrenic artery trunk (IPAT), which has at origin an endoluminal diameter of 2.6 mm and a length of 2.4 mm. The RIPA and LIPA have to origin a diameter of 2.3 mm and 1.7 mm, respectively. Knowledge of this anatomical variation is important for anatomists, interventional radiologists, vascular medicine experts, oncologists, vascular, and hepatic surgeons. |
