Mesoatrial Shunt for Budd-Chiari Syndrome

Area of Science:

• Hepatobiliary surgery
• Vascular surgery
• Interventional radiology

Background:

• Long-term efficacy of mesoatrial shunt (MAS) for Budd-Chiari syndrome (BCS) remains understudied.
• Budd-Chiari syndrome is a rare condition characterized by hepatic venous outflow obstruction.

Purpose of the Study:

• To investigate the long-term outcome and efficacy of MAS for BCS.
• To evaluate the durability and success rates of MAS in BCS patients.

Main Methods:

• Retrospective analysis of 11 patients who underwent MAS for BCS between April 1986 and November 1995.
• Inclusion of clinical presentations, laboratory data, Doppler ultrasonography, and radiological imaging for comprehensive evaluation.

Main Results:

• Mean follow-up of 17 years and 8 months, with a maximum of over 30 years.
• Significant reduction in portal pressure post-MAS (35.72 to 27.86 cm H2O, P=0.001).
• Achieved 5-year, 10-year, and 20-year shunt patency rates of 72.7%, 54.5%, and 36.4%, respectively. Survival rates were 63.3% at 10 years and 45.5% at 20 years.

Conclusions:

• Mesoatrial shunt (MAS) with enforced rings is an effective treatment for Budd-Chiari syndrome.
• Cautious perioperative management is crucial for successful MAS outcomes in BCS patients.
