Splenic Vein
Vein formed by the union (at the hilus of the spleen) of several small veins from the stomach, pancreas, spleen and mesentery.
Mesenteric Veins
Veins which return blood from the intestines; the inferior mesenteric vein empties into the splenic vein, the superior mesenteric vein joins the splenic vein to form the portal vein.
Esophageal and Gastric Varices
Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
Hypertension, Portal
Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN.
Splenic Artery
Splenic Diseases
Hypersplenism
Condition characterized by splenomegaly, some reduction in the number of circulating blood cells in the presence of a normal or hyperactive bone marrow, and the potential for reversal by splenectomy.
Portal System
A system of vessels in which blood, after passing through one capillary bed, is conveyed through a second set of capillaries before it returns to the systemic circulation. It pertains especially to the hepatic portal system.
Gastrointestinal Hemorrhage
Renal Veins
Short thick veins which return blood from the kidneys to the vena cava.
Splenic Rupture
A splenic rupture is a medical condition characterized by the traumatic tearing or disruption of the spleen, leading to potential internal bleeding and, if left untreated, potentially life-threatening complications.
Splenorenal Shunt, Surgical
Portasystemic Shunt, Surgical
Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.
Varicose Veins
Enlarged and tortuous VEINS.
Femoral Vein
Pulmonary Veins
The veins that return the oxygenated blood from the lungs to the left atrium of the heart.
Jugular Veins
Veins in the neck which drain the brain, face, and neck into the brachiocephalic or subclavian veins.
Tomography, X-Ray Computed
Pancreatitis
INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.
