Clinical presentations of portal hypertension include:

Region	Name of clinical condition	Portal circulation	Systemic circulation
Esophageal	Esophageal varices	Esophageal branch of left gastric vein	Esophageal branches of azygos vein
Rectal	Rectal varices	Superior rectal vein	Middle rectal veins and inferior rectal veins
Paraumbilical	Caput medusae	Paraumbilical veins	Superficial epigastric vein
Retroperitoneal	Splenorenal shunt	Splenic vein	Renal vein, suprarenal vein, paravertebral vein, and gonadal vein

A dilated inferior mesenteric vein may or may not be related to portal hypertension. Other areas of anastomosis include the bare area of the liver as it connects to the diaphragm, the posterior portion of the gastrointestinal tract as it touches the posterior abdominal wall, the posterior surface of the pancreas, and the inferior part of the esophagus.
