Introduction Impairment of intellectual functions is a classic symptom of portal-systemic encephalopathy in humans. The hippocampal system is important for learning and memory both in humans and animals. Different subcortical neurotransmitter systems participate in the regulation of hippocampal activity and thus play a role in the cognitive process. It has been suggested that endogenous histamine, particularly neuronal histamine in the hippocampus and hypothalamus, may be involved in the process of learning and memory in rats. Long-term portacaval anastomosis in the rat results in dramatic, region-selective changes in the brain histamine system, characterized by a marked increase in the tissue levels and a moderate elevation in the extracellular concentrations of histamine, and an increase in the tissue concentrations of tele -methylhistamine, most evident in the hypothalamus.

Preamble
Introduction
Hepatic encephalopathy (HE) may be defined as a disturbance in central nervous system function because of hepatic insufficiency. This broad definition reflects the existence of a spectrum of neuropsychiatric manifestations related to a range of pathophysiological mechanisms. Present in both acute and chronic liver failure, these neuropsychiatric manifestations are potentially reversible.
Clinical Considerations Pathophysiology The main tenet of all theories of the pathogenesis of HE is firmly accepted: nitrogenous substances derived from the gut adversely affect brain function. These compounds gain access to the systemic circulation as a result of decreased hepatic function or portal-systemic shunts. Once in brain tissue, they produce alterations of neurotransmission that affect consciousness and behavior. Abnormalities in glutamatergic, serotoninergic, -aminobutyric acid-ergic (GABA-ergic), and catecholamine pathways, among others, have been described in experimental HE (

portal-systemic shunt procedures The use of portal-systemic shunt procedures for the treatment of acutely bleeding oesophageal varices is now reserved for the 5-10% of patients who fail to respond to pharmacotherapy or sclerotherapy. Portal-systemic shunts have a high intraoperative mortality and a poor 5 year survival, particularly in patients with significant hepatic decompensation. The most common problem is chronic hepatic encephalopathy. There are two types of portal-systemic shunt procedures:
  • non-selective procedures:
      the whole portal system is decompressed include the end-to-side and the side-to-side porta-caval shunts carry a high risk of hepatic encephalopathy selective procedures:
        only decompress the oesophagogastric venous network have a lower risk of encephalopathy include the spleno-renal and the left-gastric -inferior venal cava shunts
      Transjugular intrahepatic portal-systemic shunting (TIPSS) is a new procedure which is particularly useful in the treatment of acutely bleeding oesophageal varices if liver transplantation is being considered.

Portal-Systemic Shunts
Portosystemic Shunt Congenital Portal Shunts are due to a defect in the circulation around the liver-instead of blood entering the liver to be de-toxified it is bypassed. The liver usually eliminates toxins derived from the gut. There is a bridging between the veins around the liver and the toxic material bypasses the liver causing an elevation of ammonia in the circulation. This defect may be within the liver (intrahepatic) or occur outside of the liver (extrahepatic)- most are single vessels Acquired—develops subsequent to portal hypertension (high blood pressure); typically multiple-This occurs due to a lack of valves in the portal vein permits circulatory accommodation through the shunt. Portal hypertension—usually associated with liver scarring or cirrhosis) The shunt may lead to episodic development of hepatic encephalopathy (seizures or bizarre behavior) associated with ingestion of high- protein food, and administration of certain drugs. Another effect of the shunt is the development of bladder stones due to inability of the liver to delete uric acid from the blood. SYSTEMS AFFECTED Nervous system signs include episodic hepatic encephalopathy (seizures).

The Transjugular Intrahepatic Portal-Systemic Shunt (TIPS) Procedure The transjugular intrahepatic portal-systemic shunt, or TIPS, procedure is not a surgical operation a radiologist performs the procedure in the x-ray room under x-ray guidance. During the TIPS procedure, a radiologist places a stent (a tubular device) in the middle of the liver to reroute blood flow from the portal vein, which leads to the liver, directly into the hepatic veins and to the vena cava (the largest vein leading from the liver to the heart). The TIPS procedure reroutes blood flow around the liver and reduces pressure in all abnormal veins not only in the stomach and esophagus, but also in the bowel and liver. TIPS provides immediate control of variceal bleeding in more than 90 percent of patients. Needless to say, innumerable TIPS procedures have been performed successfully at the Thomas E. Starzl Transplantation Institute. The procedure lasts from 1 to 3 hours. Patients usually remain in the hospital for two to three days after the procedure. Before discharge, the physician orders a repeat Doppler sonogram to determine whether the shunt is functioning properly.

13. Hepatic Encephalopathy / L.J. Worobetz page 537 Hepatic encephalopathy (HE) is a complex, potentially reversible neuropsychiatric condition that occurs as a consequence of acute or chronic liver disease. It is characterized by changes of personality, consciousness, behavior and neuromuscular function ( Table 20 ). Early features include reversal of sleep pattern, apathy, hypersomnia, irritability and personal neglect. In later stages, delirium and coma may occur. Neurologic signs may include hyperreflexia, rigidity, myoclonus and asterixis. Asterixis is not specific to hepatic encephalopathy and may be present in other causes of metabolic encephalopathy. Seizures and lateralizing signs are uncommon and are more commonly seen in acute than chronic liver failure. Clinically, a number of encephalopathic patterns can be observed: acute, acute recurrent, chronic recurrent and chronic permanent encephalopathy (the last often forms part of the spectrum of acquired hepatocerebral degeneration).

Hepatic Encephalopathy
DEFINITION: Hepatic encephalopathy is a syndrome seen in patients with cirrhosis of the liver. It is characterized by personality changes, intellectual impairment, and a depressed level of consciousness , fluctuating neurologic signs, asterixis or "flapping tremor," and distinctive electroencephalographic changes. An important prerequisite for the syndrome is diversion of portal blood into the systemic circulation through porto-systemic collateral vessels. Indeed, hepatic encephalopathy may develop in non-cirrhotic patients who have undergone portocaval shunt surgery. The development of hepatic encephalopathy is explained to some extent by the effect of neurotoxic substances, which occurs in the setting of cirrhosis and portal hypertension. Subtle signs of hepatic encephalopathy are seen in nearly 70% of patients with cirrhosis. Symptoms may be debilitating in a significant number of patients and are seen in 24-53% of patients who undergo portosystemic shunt surgery. About 30% patients dying of end-stage liver disease will experience significant encephalopathy, approaching coma. Encephalopathy may be acute and reversible or chronic and progressive . In severe cases, irreversible coma and death may occur. Acute episodes may recur with variable frequency

Distal spleno-renal shunt was made in 20 patients. In six patients this was combined with partial splenic resection. Fifteen cases underwent mesocaval shunt with H-graft, while in 4 patients coronaro-caval shunt was made. Postoperative follow-up studies demonstrated stable liver function tests in 36 cases. Variceal size was greatly reduced in 27 patients. No variceal bleeding occurred during the immediate postoperative period. Haematologic indices of hypersplenism were reversed in 18 cases. Ascites did not recur in 27 patients. In 4 cases shunts became thrombosed. In the very first 2 cases this occurred during immediate postoperative period, in another 2 after couple of years. Acute postoperative encephalopathy was recorded in 3 patients, while chronic in 4 cases. Hepatic perfusion index was slightly decreased in 4 patients. Thirty-four patients survived from 2.5 to 4.5 years in average.

Esophageal Varices
Definition:
Esophageal varices are the enlarged veins (varicose veins) located in the lower end of the esophagus (swallowing tube). These veins develop because cirrhosis blocks blood from flowing freely through the liver. Once the blood is blocked from flowing through the liver, it must find another way to return to the heart. The veins surrounding the esophagus and stomach provide a pathway for blood to return to the heart. Over time, these veins become larger and develop into varicose veins or varices. The enlarged veins surrounding the esophagus are esophageal varices, and the veins surrounding the stomach are gastric varices. If the pressure within these veins becomes high enough the veins can rupture, leading to life threatening bleeding.
Symptoms:
Bleeding from varices is generally brisk and associated with symptoms. The most frequent symptoms include: weakness, light-headedness, nausea, vomiting of blood or coffee colored material, and passage of bowel movements that are bloody or black (like tar). Bleeding from varices represents a life-threatening medical emergency. If you develop signs of bleeding, someone should take you to the nearest hospital immediately.

portal systemic encephalopathy Hepatic encephalopathy is a metabolic disorder of the central nervous system and neuromuscular system that may complicate liver failure from any cause. It is particularly associated with advanced cirrhosis on account of the diffuse parenchymal damage and portosystemic shunting. The features depend on the aetiology and precipitating factors, eventually developing into stupor and then coma. Some aetiologies of the hepatic failure, for example paracetamol overdose, can precipitate this condition within three or four days, with a very rapid progression through the grades of encephalopathy. Other aetiologies, for example viral hepatitis, are associated with a much more variable onset. The grade of the encephalopathy can be used to predict the prognosis - for example grades I and II have and excellent prognosis, grades III and IV have poorer prognoses with the development of complications.
