Overview
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]

- 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 intra-abdominal pressure may lead to respiratory problems or abdominal hernias.[7]
- 10% of hospitalized patients with cirrhosis will involve in spantanous bacterial peritonitis (SBP).[8]
- If left untreated, 20-40% of patients with SBP may progress to death.[9]
- Hepatorenal syndrome incidence rate in cirrhotic patients is 20% in 1 year and 40% in 5 years period.[10]
- If left untreated, 100% of patients with type 1 hepatorenal syndrome may progress to death.[11]
- If left untreated, most of the patients with portal hypertension and cirrhosis may progress to hepatic encephalopathy.
Complications
- Common complications of portal hypertension include:
- Spontaneous bacterial peritonitis
- Hepatorenal syndrome
- Hepatic encephalopathy
- Congestive gastropathy
- Hypersplenism
- Ascites
- Variceal bleeding
- Renal failure
- Hepatic hydrothorax
- Hepatopulmonary syndrome
- Portopulmonary hypertension
- Cirrhotic cardiomyopathy
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.[12]
- When ascites occurs the 2-year mortality rate become 50%, without liver transplantation.[13]
- When SBP occurs the mortality rate of 20-40% is expected.[9]
- Prognosis is generally very poor in type 1 hepatorenal syndrome, all of them would die despite appropriate treatments.[11]
