What causes a Splenorenal shunt?
What causes a Splenorenal shunt?
Results: The elevation of portal pressure and resistance in cirrhosis leads to an increased gradient between portal pressure and systemic blood flow, potentially initiating portosystemic (PS) shunt formation.
What is spontaneous Splenorenal shunt?
Spontaneous splenorenal shunts (SSRSs) are a common type of portosystemic shunt (occurring in an estimated 14% to 60% of patients with cirrhosis) that decompress the portal circulation through the left renal vein and inferior vena cava (Fig. 1).
How is a portosystemic shunt diagnosed?
What is the diagnosis? Diagnosis of a portosystemic shunt (PSS ) can be made from bloodwork, urinalysis, abdominal ultrasound, and other modalities, such as contrast enhanced X-Rays, computed tomography (CT) scan, MRI, and nuclear scintigraphy. Often, the definitive diagnosis will be made at the time of surgery.
What is a large Splenorenal shunt?
A splenorenal shunt refers to an abnormal collateral portosystemic communication between the splenic vein and the left renal vein. It is one of the features of portal hypertension.
What are Splenorenal varices?
Varices develop across the esophagus and stomach from the pressure in the portal vein. The backup of pressure also causes the spleen to become enlarged. Fig 2: After the distal splenorenal shunt surgery is performed.
What is a Rex shunt?
The Rex Shunt The shunt bypasses the blocked portal vein and restores venous blood flow to the liver. A vein (usually the jugular vein in the neck) is used to build a bridge around the blockage. Blood flows from the large intestinal veins, across the bridge, around the blockage and back into the liver.
What is Ehpvo?
Extrahepatic portal venous obstruction (EHPVO) is the commonest cause of portal hypertension and variceal bleeding in children.
What do portosystemic shunts cause?
Portosystemic shunts are vascular anomalies that cause blood from the portal circulation to bypass the liver and flow into the systemic circulation, allowing metabolic byproducts that are normally removed and detoxified by the liver to accumulate in the circulation.
What does portosystemic shunting mean?
A portosystemic shunt (PSS) is an abnormal connection between the portal vascular system and systemic circulation. This means that a portion of the toxins, proteins and nutrients absorbed by the intestines bypass the liver and are shunted directly into the systemic circulation.
What is the distal splenorenal shunt procedure called?
What is the distal splenorenal shunt procedure? A distal splenorenal shunt is a surgical procedure. During the surgery, the vein from the spleen (called the splenic vein) is detached from the portal vein and reattached to the left kidney (renal) vein.
What kind of shunt is the splenic vein?
A splenorenal shunt refers to an abnormal collateral portosystemic communication between the splenic vein and the left renal vein. It is one of the features of portal hypertension.
Can a cirrhotic patient have a spontaneous splenorenal shunt?
Spontaneous splenorenal shunt is a rare condition, sometimes causing complications in cirrhotic patients. We report a 30-year old man with liver cirrhosis, hypertrophic caudal lobe and spontaneous splenorenal shunt.
What kind of shunt is used for portal hypertension?
Portal hypertension is a condition characterized by increased pressure in the portal vein (the vein that carries blood from the digestive organs to the liver). Your physician has chosen the distal splenorenal shunt procedure to treat this condition.
