What does a Splenorenal shunt do?
What does a Splenorenal shunt do?
This surgical procedure detaches the splenic vein from the portal vein and reattaches it to the left kidney (renal) vein to relieve pressure in varices caused by portal hypertension.
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 is a 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).
What is Devascularization procedure?
Devascularization procedures aim to control bleeding from varices in the esophagogastric region. They do not control bleeding from ectopic varices, nor do they treat the underlying disease. However, splenectomy, which is part of most described devascularization procedures, can effectively treat hypersplenism.
What is superior mesenteric vein?
The superior mesenteric vein (SMV) is a major venous tributary of the abdominal cavity. Embryologically derived in association with the vitelline vein, the superior mesenteric vein lies lateral to the superior mesenteric artery (SMA) and serves to drain the vast majority of the organs of the abdominal cavity.
Which surgery is not use esophageal varices?
Esophagogastric devascularization procedures are performed to control bleeding from varices in the esophagogastric region. They are not intended as treatment of the underlying disease, and they do not control bleeding from ectopic varices. Splenectomy is commonly performed as part of esophagogastric devascualrization.
What is gastric Devascularization?
Gastric devascularization is a useful salvage procedure for the patient with DHG because it can be accomplished rapidly, with few complications, has a low rebleed rate, and causes no permanent sequelae.
Where does a distal splenorenal shunt take place?
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.
How are spontaneous splenorenal shunts used in cirrhosis?
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.
What kind of shunt is the splenic vein?
Dr Henry Knipe ◉ ◈ and Dr Yuranga Weerakkody ◉ et al. 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 happens to the spleen after shunt surgery?
Fig 1: Portal hypertension before the distal splenorenal shunt surgery is performed. 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.
