Assessing surgical risk in idiopathic portal hypertension: some answers, an extrapolation, and more questions.

Summary of "Assessing surgical risk in idiopathic portal hypertension: some answers, an extrapolation, and more questions."

Preoperative risk assessment of patients with chronic liver disease is an important part of hepatology practice. Patients with cirrhosis undergoing major surgery are at significantly increased risk of postoperative morbidity and mortality. It is the hepatologist's responsibility to estimate such risk and advise the surgical team and the patient on how to proceed. Continued advances in surgical technologies and medical care are leading to increasing numbers of referrals for preoperative evaluation. This article is protected by copyright. All rights reserved.

Medical and Biotech [MESH] Definitions

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.

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).

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.

A type of surgical portasystemic shunt to reduce portal hypertension with associated complications of esophageal varices and ascites. It is performed percutaneously through the jugular vein and involves the creation of an intrahepatic shunt between the hepatic vein and portal vein. The channel is maintained by a metallic stent. The procedure can be performed in patients who have failed sclerotherapy and is an additional option to the surgical techniques of portocaval, mesocaval, and splenorenal shunts. It takes one to three hours to perform. (JAMA 1995;273(23):1824-30)

A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
