Partial portal decompression has become a popular option in the treatment of complicated portal hypertension. This study was undertaken to report long-term follow-up after partial portal decompression obtained utilizing 8 mm prosthetic H-graft portacaval shunts. A total of 110 consecutive patients underwent H-graft portacaval shunting through a protocol that detailed ...

Thrombocytopenia is frequently present in patients with cirrhosis. The effect of portal decompression on thrombocytopenia using a variety of shunt procedures has been contradictory. Transjugular intrahepatic portosystemic shunt (TIPS) has been proposed as a less invasive procedure for portal decompression, mainly for control of variceal bleeding or intractable ascites. Its ...

Although epilepsy is commonly associated with shunt-treated hydrocephalus, its relation to the shunting procedure and the criteria identifying postoperative epilepsy remain controversial. Of 283 patients shunted at Würzburg University Hospital over a 24-year period (1970 to 1994), 182 were followed up for a minimum of 1 year after shunt insertion ...

BACKGROUND: The bidirectional cavopulmonary shunt has become a mainstay in the palliation of patients with a functional single-ventricle heart. However, there remain a number of unresolved issues regarding this procedure, many of which concern the response of the pulmonary vasculature to this unique circulatory physiology. Among the issues of debate ...

Internal drainage of cerebrospinal fluid (CSF) to the abdominal cavity via a ventriculo-peritoneal shunt (VPS) is a procedure that is commonly used for the treatment of obstructive hydrocephalus. As this condition is often caused by brain tumors blocking the natural CSF pathways, a VPS, as an artificial anastomosis, can provide ...

Shunt surgery is considered to be the treatment of choice in patients with non-cirrhotic portal hypertension. There is little data on the effect of side-to-side lieno-renal (SSLR) shunt on oesophageal variceal size, splenic size and splenic pulp pressure (SPP) in patents with non-cirrhotic portal hypertension.
