“…Although the LGV usually feeds directly into the PV, anatomic variants with anastomosis at the splenic vein (SV) or splenomesenteric trunk (SMT) have also been reported 7 . There are also case reports in which the LGV drains directly into the liver by merging with the end of the left portal branch 8–10 …”

“…Vascular variabilities, such as capsular veins drain into adjacent hepatic sinusoids, accessory cystic veins drain into the liver parenchyma of segments IV-V, parabiliary system from the head of the pancreas, duodenum and distal stomach drain into the posterior part of segment IV, veins from the gastric antrum and pancreatic head into segments I and IV, which are third hepatic inflow tracts, may drain the systemic venous circulation into the liver [27][28][29] . Focal intensively enhanced areas are seen on HAP images of CT or MR, segmental staining is seen on arteriogram because of the early inflow of contrast material compared with the inflow into the surrounding parenchyma, which receives contrast material mainly from the splenic and superior mesenteric veins.…”

In this article, we have reviewed the hepatic perfusion d i s o r d e r ( H P D ) , e t i o p a t h o g e n e s i s o f H P D a n d corresponding diseases. Review of the literature was based on computer searches (PubMed, Index Medicus) and personal experiences. We considered HPD reflects perfusion differences due to redistribution of arterial blood flow among segments, subsegments and lobes of the liver. The plain CT scan findings of HPD manifests as triangular or wedge-shaped areas of low attenuation. On contrast-enhanced CT scan, HPD manifests multiple (or single) transient wedge-shaped, rotundloid or irregular appearance, homogeneous hyperattenuation (in less cases, hypoattenuation) during the hepatic arterial phase (HAP) and isoattenuated or slightly hyperattenuated areas during the portal arterial phase. Dynamic enhanced magnetic resonance (MR) features are similar to enhanced CT scan. Angiographic findings include non-opacification of portal vein on portograms or wedge-shaped segmental staining in arterial and parenchymal phases on hepatic angiograms. The causes of HPD are arterioportal shunts (APS), intrahepatic vascular compressions and portal vein occlusion, steal phenomenon by hypervascular tumors, vascular variations and any other unknown reasons. It is very important for radiologists to be familiar with the various appearances of HPD to avoid false-positive diagnosis of pseudolesions and not to overestimate the extent of the disease.

“…The LGV usually runs across the dorsal side of the common hepatic artery (CHA) and the ventral side of splenic artery (SA) [21] (Figs. 1, 2), although, in some individuals, the LGV drains directly into the liver [3, 6, 13, 24, 28] (Fig. 3).…”

PurposeThe left gastric vein (LGV) is an important blood vessel requiring dissection during gastric surgery. We describe a rare anatomic variant of the LGV.MethodsThe LGV drainage pattern was analyzed relative to intraoperative vascular anatomy in 2,111 patients with gastric cancer who underwent radical resection from May 2007 to September 2012. The incidence of the anatomic variant was determined, and the diameter and length of the LGV and the distances from the end of the LGV to the splenoportal confluence and the root of the left gastric artery (LGA) were measured by abdominal CT reconstruction.ResultsIn 6 of the 2,111 (0.28 %) gastric cancer patients who underwent radical resection, the LGV descended on the left side of the gastropancreatic fold, ran across the dorsal side of the splenic artery and drained into the splenic vein. The mean diameter and length of the LGV were 5.10 ± 0.40 and 37.40 ± 5.19 mm, respectively, and the mean distance from the end of the LGV to the splenoportal confluence was 13.05 ± 0.86 mm. The closer the LGV and LGA were to the root, the greater the distance between them, with a mean 13.85 ± 1.02 mm between the end of the LGV and the root of the LGA.ConclusionsIn this rare anatomic variant, the LGV descends along the gastropancreatic fold, runs across the dorsal side of the splenic artery and drains into the splenic vein. Knowledge of this rare anatomic variant will help avoid damage to the LGV during gastric surgery.
