Pancreatic malignancy

The most common veins involved are the SMV, portal vein, and splenic vein. Specific signs of venous involvement are reduction in diameter of the SMV, the presence of a partial or complete thrombosis, a ‘teardrop’ shape (Figure 12.12), and dilatation of SMV tributaries (45), especially enlargement of the posterosuperior pancreaticoduodenal vein (PDV) and visualization of the inferior PDV, while enlargement of the gastrocolic trunk is not conclusive (46). It is also important to evaluate all other venous structures, such as the inferior mesenteric vein, the first venous duodenal branch, and their distances from the tumour and the spleno-portal confluence (40,47). Short involvement (<2 cm) of the SMV allows resection and reconstruction.
Auxiliary Heterotopic Rat Liver Transplantation
Published in Waldemar L. Olszewski, CRC Handbook of Microsurgery, 2019
Grafts of 30 to 35% of the liver mass are used. The median, left, and if desired, the gastric lobes are resected by simple ligation and transection. The portal vein is mobilized for a sufficient length, usually from the splenic vein to the hilus. The pancreaticoduodenal vein is ligated. The celiac artery is ligated to prevent excessive bleeding from the pancreatic bed during mobilization of the bile duct. The hepatic artery is ligated. Skeletonization of the supra- and infrahepatic vena cava is carried out, and the left suprarenal vein is ligated (Figure 2B). Ligatures are placed around the suprahepatic vena cava and the vena porta to keep the perfusion cannula in place. Just prior to graft perfusion 250 U heparin is given i.v. The donor preparation is completed, and the graft can be perfused and removed after preparation of the recipient.

Head and neck of the pancreas are drained by anterior and posterior pancreaticoduodenal veins which drain into the portal vein. A branch of the anterior pancreaticoduodenal venous arcade joins the right gastroepiploic vein to form the gastrocolic vein draining into the superior mesenteric vein. Veins draining the body and the tail directly join the splenic vein.
Three-Port Versus Five-Port Laparoscopic Distal Gastrectomy for Early Gastric Cancer Patients: A Propensity Score Matched Case-Control Study
Published in Journal of Investigative Surgery, 2018
Dissection of the greater omentum was started from the mid-portion of the transverse colon, continuing toward the lower pole of the spleen. After the left gastroepiploic vessels were ligated and the LN station 4sb was dissected, right-sided omentectomy was continued toward the hepatic flexure of the colon. As the dissection of the avascular plane among the stomach, the duodenum and the colon progressed, the gastrocolic trunk of Henle and the anterior superior pancreaticoduodenal vein appeared. After the identification of these vessels, the right gastroepiploic vessels could be identified and ligated, and LN station 6 could be dissected. Then, the right gastric vessels were ligated at their roots and LN station 5 was dissected.
Massive gastrointestinal bleeding due to ectopic varix in distal duodenum: a case report

Duodenal ectopic varices (DEV) are a subgroup of ectopic varices that includes a diverse set of vascular connections including portosystemic shunts, portal-portal anastomoses as well as mesenteric-to-portal shunts. The afferent feeders of DEV include the superior and inferior pancreaticoduodenal veins, cystic branches of the superior mesenteric veins, the gastroduodenal vein and the pyloric vein [7–10]. There are numerous vascular sources that can act as the efferent branch of the DEV including the right gonadal vein, the capsular renal veins [7,8,11], the left gonadal vein, directly into the inferior vena cava and the right renal vein [7]. In our case, the duodenal varix outflow was into the left renal vein proper.
Multifocal gastrointestinal varices: a rare manifestation of immunoglobulin G4-related disease
Published in Postgraduate Medicine, 2019
The branches of the splenic vein include the short gastric vein (distributed at the fundus and left part of the gastric greater curvature) and the left gastroepiploic vein (distributed at the anterosuperior and posteroinferior surfaces of the stomach) [3]. Both the pancreaticoduodenal vein (from the pancreas and duodenum) and middle colic vein (from the transverse colon) flow into the superior mesenteric vein [3]. In light of the anatomic relationship, it is reasonable to discover that segmental occlusion in the portal venous system leads to the multiple GI varices in our case.
