In medicine, a distal splenorenal shunt procedure (DSRS), also splenorenal shunt procedure and Warren shunt, [1] is a surgical procedure in which the distal splenic vein (a part of the portal venous system) is attached to the left renal vein (a part of the systemic venous system).
Methods of treating the portal hypertension include: transjugular intrahepatic portosystemic shunt (TIPS), distal splenorenal shunt procedure, or liver transplantation. [citation needed] Nutritional supplementation is necessary if the person has been unable to eat for more than four days. [10]
Warren was a pioneer in surgery for portal hypertension and developed the distal splenorenal shunt. [3] He was the recipient of many honours and served as President of the American College of Surgeons. His memory is honored by an annual lectureship at Emory University.
The side-to-side shunt is often preferred in the management of refractory ascites associated with the portal hypertension. [6] End-to-side portacaval shunt: connects the end of the portal vein to the side of the inferior vena cava, creating a new connection between the two vessels. The end-to-side may be used if the patient's anatomy calls for it.
A Peritoneovenous shunt: (also called Denver shunt) [2] is a shunt which drains peritoneal fluid from the peritoneum into veins, usually the internal jugular vein or the superior vena cava. It is sometimes used in patients with refractory ascites. It is a long tube with a non-return valve running subcutaneously from the peritoneum to the ...
The shunt also has a valve which serves to maintain one-way flow of the CSF and regulates the flow rate. The end with the catheter is placed in the third ventricle to drain the excess CSF and the other end is placed in the peritoneal cavity or atrium of the heart (making it a ventriculoperitoneal or ventriculoatrial shunt, respectively). The ...
Vascular access steal syndrome is a syndrome caused by ischemia (not enough blood flow) resulting from a vascular access device (such as an arteriovenous fistula or synthetic vascular graft–AV fistula) that was installed to provide access for the inflow and outflow of blood during hemodialysis.
Another leading cause of shunt failure is a blockage of the shunt at either the proximal or distal end. At the proximal end, the shunt valve can become blocked due to the buildup of excess protein in the CSF. The extra protein will collect at the point of drainage and slowly clog the valve. The shunt can also become blocked at the distal end if ...
