Overview
Portal hypertension is increased hepatic venous pressure gradient (HVPG) above 5 mmHg. The symptoms of portal hypertension usually develop in the third to fourth decades of life, and generally start with symptoms such as esophageal varices, caput medusae, spider angioma, and splenomegaly. Esophageal varices typically developes at the rate of 5-15% per year in cirrhosis patients. Most of the cirrhotic patients will develop the varices, atleast once during the lifetime. Approximately 60% of patients with cirrhosis develop ascites in 10 years. 10% of hospitalized patients with cirrhosis will involve in spontaneous bacterial peritonitis (SBP). If left untreated, 20-40% of patients with SBP may progress to death. The presence of variceal bleeding, spontaneous bacterial peritonitis, and hepatorenal syndrome are associated with a particularly poor prognosis among patients with portal hypertension. They are the leading causes of death among patients with portal hypertension.
Natural History, Complications, and Prognosis
- Portal hypertension is increased hepatic venous pressure gradient (HVPG) above 5 mmHg.
- 90% of the cases are due to hepatic cirrhosis.[1]
- The stage of cirrhosis severity is determined base on Child-Pugh-Turcotte (CPT) scoring system, including Child A if 5-6 points, Child B if 7-9 points, and Child C if 10-15 points.
| Parameter | Points | ||
|---|---|---|---|
| 1 | 2 | 3 | |
| Ascites | None | Mild/Moderate | Tense |
| Hepatic encephalopathy | None | Grade 1-2 | Grade 3-4 |
| Bilirubin μMol/L (mg/dL) | <34.2 (<2) | 34.2–51.3 (2-3) | >51.3 (>3) |
| Albumin g/L (g/dL) | >35 (>3.5) | 28–35 (2.8–3.5) | <28 (<2.8) |
| PT (Sec) or INR |
<4 | 4–6 | >6 |
| <1.7 | 1.7–2.3 | >2.3 | |
Natural History
- The symptoms of portal hypertension usually develop in the third and fourth decades of life, and generally start with symptoms such as esophageal varices, caput medusae, spider angioma, and splenomegaly.
- The HVPG threshold for portal hypertension to become clinically symptomatic is 10-12mm Hg.[2]
- Esophageal varices occur when the HVPG reaches 10 mmHg. 40% of Child A and 85% of Child C cirrhosis may progress to esophageal varices.[3]
- Esophageal varices are typically developed 5-15% per year after cirrhosis. Most of the cirrhotic patients will develop the varices during the lifetime.[1]
- Esophageal varices enlarge and progress about 8% per year.[4] The varices are bleeding 5-15% per year.[5]
 |  | ||||||||||||||||||||||||||||||||||
| Gastroesophageal varices type 1 Extend along the lesser curvature | Gastroesophageal varices type 2 Extend along the fundus | ||||||||||||||||||||||||||||||||||
 |  | ||||||||||||||||||||||||||||||||||
| Isolated gastric varices type 1 Located in the fundus and tend to be tortuous and complex | Isolated gastric varices Located in the body, antrum, or around the pylorus | ||||||||||||||||||||||||||||||||||
- Approximately 60% of patients with cirrhosis develop ascites in 10 years.[6]
- At least 1500 cc ascites is necessary to become identifiable through physical exam. The severe increase in intraabdominal pressure may lead to respiratory problems or abdominal hernias.[7]
- Based on grade of cirrhosis, international ascites club presented a grading system.[8]
| Grade | Definition |
|---|---|
| Grade 1 | Mild ascites only detectable by ultrasound |
| Grade 2 | Moderate ascites evident by moderate symmetrical distension of abdomen |
| Grade 3 | Large or gross ascites with marked abdominal distension |
- 10% of hospitalized patients with cirrhosis will involve in spontaneous bacterial peritonitis (SBP).[9]
- If left untreated, 20-40% of patients with SBP may progress to death.[10]
- Hepatorenal syndrome incidence rate in cirrhotic patients is 20% in 1 year and 40% in 5 years period.[11]
- If left untreated, 100% of patients with type 1 hepatorenal syndrome may progress to death.[12]
- If left untreated, most of the patients with portal hypertension and cirrhosis may progress to hepatic encephalopathy.
- Grading for different stages of hepatic encephalopathy, called West Haven Criteria, is as following:[13]
| West Haven Criteria hepatic encephalopathy grading | |||||||||||||||||||||||||||||||||||
| Grade 1 | Grade 2 | Grade 3 | Grade 4 | ||||||||||||||||||||||||||||||||
| •Mild loss of consciousness •Euphoria or anxiety • Lowered attention span •Impaired performance of addition | •Lethargy or apathy •Minimal disorientation to time and place •Subtle personality change •Inappropriate behavior •Impaired performance of subtraction | •Somnolence to semi-stupor, but responsive to verbal stimuli •Confusion •Gross disorientation | •Coma (unresponsive to verbal or noxious stimuli) | ||||||||||||||||||||||||||||||||
Complications
- Common complications of portal hypertension include:
Prognosis
- The presence of variceal bleeding, spontaneous bacterial peritonitis, and hepatorenal syndrome are associated with a particularly poor prognosis among patients with portal hypertension. They are the leading causes of death among patients with portal hypertension.
- When esophageal varices bleed the average rate of 6-week mortality become ≥ 20%, despite improved therapies.[14]
- When ascites occurs the 2-year mortality rate become 50%, without liver transplantation.[15]
- When SBP occurs the mortality rate of 20-40% is expected.[10]
- Prognosis is generally very poor in type 1 hepatorenal syndrome, all of them would die despite appropriate treatments.[12]
- General prognosis in cirrhotic patients is as follows:
| HVPG of 10 mmHg | • Gastroesophageal varices • Hepatocellular carcinoma • Decompensation after hepatocellular carcinoma resection | ||||||||||||||||||||||||||||||||||||||
| Compensated cirrhosis | HVPG of 12 mmHg | • Variceal bleeding | |||||||||||||||||||||||||||||||||||||
| HVPG of 16 mmHg | • First decompensation after varices • Mortality | ||||||||||||||||||||||||||||||||||||||
| Prognostic significance of HVPG in cirrhotic patients | |||||||||||||||||||||||||||||||||||||||
| HVPG of 16 mmHg | • Variceal rebleeding • Mortality | ||||||||||||||||||||||||||||||||||||||
| HVPG of 20 mmHg | • Uncontrollable active variceal bleeding • Low 1-year survival | ||||||||||||||||||||||||||||||||||||||
| Decompensated cirrhosis | |||||||||||||||||||||||||||||||||||||||
| HVPG of 22 mmHg | • Mortality in alcoholic cirrhosis and acute alcoholic hepatitis | ||||||||||||||||||||||||||||||||||||||
| HVPG of 30 mmHg | • Spontaneous bacterial peritonitis (SBP) | ||||||||||||||||||||||||||||||||||||||
