Management of Portal Hypertension
The management of portal hypertension should follow a stepwise approach based on the clinical presentation, with transjugular intrahepatic portosystemic stent-shunt (TIPSS) recommended for refractory variceal bleeding and selected patients with refractory ascites. 1
First-Line Management
Variceal Bleeding
- Non-selective beta blockers (NSBBs) remain the pharmacotherapy of choice for primary prevention of variceal bleeding and secondary prophylaxis 2
- For acute variceal bleeding, early administration of vasoactive agents followed by endoscopic therapy is recommended 1
- Combination therapy with endoscopic treatment plus vasoactive drugs significantly improves 5-day hemostasis rates (77% vs 58% with endoscopy alone) 1
- Antibiotic prophylaxis in cirrhotic patients with acute upper gastrointestinal bleeding reduces mortality, bacterial infections, and rebleeding 1
- Carvedilol is more potent than traditional NSBBs (propranolol, nadolol) in reducing portal pressure and is better tolerated in many patients 3, 2
Ascites and Other Complications
- Medical management with diuretics is first-line for ascites 1
- For portal hypertensive gastropathy, NSBBs and iron therapy are recommended as initial treatment 1
- Regular monitoring of hemodynamic parameters is essential in patients with portal hypertension 4
Advanced Management: TIPSS Indications
For Variceal Bleeding
- TIPSS is strongly recommended for gastro-oesophageal variceal bleeding refractory to endoscopic and drug therapy (as defined by Baveno 6 criteria) 1
- Early or pre-emptive TIPSS should be considered within 72 hours of a variceal bleed in patients who:
- Have Child's C disease (C10-13) or MELD ≥19
- Are bleeding from oesophageal varices or GOV1/GOV2 gastric varices
- Are hemodynamically stable 1
- Salvage TIPSS is not recommended where Child-Pugh score is >13 1
- In secondary prevention of gastric variceal bleeding, TIPSS ± embolization is recommended when patients rebleed despite endoscopic injection therapy 1
For Ascites
- In selected patients with refractory or recurrent ascites, TIPSS is strongly recommended provided there are no contraindications 1
- TIPSS should only be undertaken after discussion with the regional transplant center for transplant-eligible patients 1
- Contraindications for TIPSS in ascites include:
- Bilirubin >50 μmol/L
- Platelets <75×10^9
- Pre-existing encephalopathy
- Active infection
- Severe cardiac failure
- Severe pulmonary hypertension 1
For Other Complications
- Selected patients with refractory hepatic hydrothorax may be considered for TIPSS insertion 1
- TIPSS is recommended for Budd-Chiari syndrome when patients fail to respond to medical therapy with anticoagulation or hepatic vein interventions 1
- TIPSS for hepatorenal syndrome remains experimental 1
- For bleeding from ectopic varices refractory to local and pharmacological therapies, TIPSS with embolization is suggested 1
TIPSS Procedure and Follow-up
- Covered stents are preferred over bare metal stents due to superior patency rates 1
- A Doppler ultrasound is recommended one week after TIPSS implantation in patients with prothrombotic conditions 1
- Regular Doppler ultrasound follow-up at 6-12 month intervals is recommended 1
- The main complications of TIPSS include hepatic encephalopathy (affecting approximately one-third of patients), bleeding, infection, heart failure, liver failure, and kidney failure 1
Special Considerations
- Portal vein thrombosis is not an absolute contraindication to TIPSS placement, although cavernoma presence is associated with higher failure rates 1
- In patients with esophageal varices or history of variceal bleeding, appropriate prophylaxis should be maintained with NSBBs or endoscopic band ligation 4
- The role of TIPSS in idiopathic non-cirrhotic portal hypertension should follow similar indications as in cirrhosis 1
By following this structured approach to portal hypertension management, clinicians can optimize outcomes while minimizing complications in this complex patient population.
