Multidetector computed tomography for preoperative identification of left gastric vein location in patients with gastric cancer.

Background: The area near the left gastric vein (LGV) is a challenging site at which to perform dissection of the lymph nodes during gastrectomy. Therefore, knowledge of the precise location of the LGV is important. The objective of this study was to examine the usefulness of multidetector computed tomography (MDCT) for the identification of the LGV.
