Gastric varices may also be found in patients with thrombosis of the splenic vein, into which the short gastric veins that drain the fundus of the stomach flow. The latter may be a complication of acute pancreatitis , pancreatic cancer , or other abdominal tumours, as well as hepatitis C .
Portal hypertensive gastropathy can also be treated with endoscopic treatment delivered through a fibre-optic camera into the stomach. Argon plasma coagulation and electrocautery have both been used to stop bleeding from ectatic vessels, and to attempt to obliterate the vessels, but have limited utility if the disease is diffuse.
The splenic vein is formed from small venules that leave the spleen. It travels above the pancreas, alongside the splenic artery.It collects branches from the stomach and pancreas, and most notably from the large intestine (also drained by the superior mesenteric vein) via the inferior mesenteric vein, which drains in the splenic vein shortly before the origin of the hepatic portal vein.
Balloon-occluded retrograde transvenous obliteration (BRTO) is an endovascular procedure used for the treatment of gastric varices.When performing the procedure, an interventional radiologist accesses blood vessels using a catheter, inflates a balloon (e.g. balloon occlusion) and injects a substance into the variceal blood vessels that causes blockage of those vessels.
Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg.

Splenopancreatic and gastric disconnection (SPGD) [ edit ] DSRS is typically done with splenopancreatic and gastric disconnection (ligation of the gastric veins and pancreatic veins (that drain into the portal vein ) and complete detachment of the splenic vein from the portal venous system ), as it improves the outcome.
Splenic vein; Superior mesenteric vein; Inferior mesenteric vein; The superior mesenteric vein and the splenic vein come together to form the actual hepatic portal vein. The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein.
Splenectomy is then performed. The abdominal esophagus is devascularized from the stomach. The posterior gastric vagus nerve requires ligation due to its close proximity. The lesser curvature of the stomach and abdominal esophagus are then devascularized, and the cardioesophageal branches of the left gastric vessels are ligated and divided.
