Intrapericardial Blalock-Taussig shunt

G Pappas, C R Hawes

    The Journal of Thoracic and Cardiovascular Surgery
    |March 1, 1982

    Summary

    A novel intrapericardial approach for Blalock-Taussig (B-T) shunts offers advantages for infants with cyanotic heart disease. This method reduces complications and operating time compared to the standard B-T shunt procedure.

    Area of Science:

    • Cardiovascular Surgery
    • Pediatric Cardiology
    • Congenital Heart Disease

    Background:

    • The standard Blalock-Taussig (B-T) shunt is a common palliative procedure for cyanotic heart disease with reduced pulmonary blood flow in infants.
    • Standard B-T shunt procedures carry risks including phrenic nerve injury, excessive bleeding, and prolonged operating times due to extensive mediastinal dissection.

    Purpose of the Study:

    • To describe an alternative intrapericardial approach for Blalock-Taussig (B-T) shunt creation.
    • To evaluate the feasibility, safety, and efficacy of this novel intrapericardial technique in infants.

    Main Methods:

    • A modified Blalock-Taussig (B-T) shunt procedure using an intrapericardial approach was performed on 17 infants (age 1 day to 2 years).
    • This technique involves minimal subclavian artery dissection and anastomosis to the pulmonary artery medial to the superior vena cava (SVC) and lateral to the aorta.

    Main Results:

    • The intrapericardial shunt procedure was successfully performed in 17 infants.
    • Shunt function was good in 94% of patients at an average follow-up of 17 months (range 1-44 months).
    • Potential benefits observed include elimination of phrenic nerve injury, reduced dissection, shorter operating time, and decreased intraoperative hemorrhage.

    Conclusions:

    • The intrapericardial approach for Blalock-Taussig (B-T) shunt offers a promising alternative to the standard procedure.
    • This technique may lead to improved patient outcomes by minimizing surgical complications and enhancing shunt patency.
