(A) A typical VTSS (white dashed square) formed by a replaced LHA entering liver through FLV was seen in the arterial phase of a contrast-enhanced CT scan. (B) A schematic diagram of VTSS. The vessel represents the aberrant artery, which is sailing though a “strait” composed of S1 and S2 of the liver (C) The patient was confirmed to have a replaced LHA arising from LGA (Michel’s type II HAV) by DSHA. The corresponding part of the replaced LHA forming VTSS was highlighted by the white dashed rectangle. LHA, left hepatic artery; LGA, left gastric artery; RHA, right hepatic artery; S, segment of the liver; T, thoracic vertebrae.
