Abstract

Objective

To investigate the imaging findings and hepatic artery variations encountered in patients with aberrant left gastric vein (ALGV).

Methods

A retrospective database search between January 2014 and November 2018 was carried for ALGV. The course and types (1–3) of ALGV, the presence of associated liver lesions, and coexistence of hepatic artery variations were reviewed on CT images.

Results

A total of 32 patients (22 men, 68.7%) with a mean age of 52.5 years (range 22–76 years) were found to have ALGV. The prevalence of ALGV was 0.073%. The most frequent type of ALGV was type 1 (n = 22, 68.7%), followed by type 3 (n = 7, 21.8%) and type 2 (n = 3, 9.3%). We noticed mild-to-severe parenchymal hyperdensity at the posterior aspect of segments II and III in patients with type 1 (n = 20/22) and type 2 (n = 2/3) ALGV consistent with fat sparing due to third inflow effect. Two out of seven patients with type 3 ALGV had main portal vein thrombosis; however, the presence of ALGV maintained left portal vein flow in these patients. Twelve (37.5%) patients had accompanying hepatic artery variation. Left hepatic and right hepatic artery variations were detected in 8 (25%) and 2 (6.25%) of the patients, respectively. In 2 patients, Michels type IV variation was detected.

Conclusion

Aberrant left gastric vein is associated with hepatic artery variations, which can be important for preoperative and pretransplant planning.
