  • Title: The Blalock-Taussig shunt in the first two years of life: a safe and effective procedure.
    Author: Tyson KR, Larrieu AJ, Kirchmer JT.
    Journal: Ann Thorac Surg; 1978 Jul; 26(1):38-41. PubMed ID: 666406.
    Abstract:
    Many surgeons have been reluctant to perform Blalock shunts in patients who are in infancy or early childhood (less than 24 months old) and have done instead direct aortopulmonary anastomoses. Recently, others have advocated complete repair of tetralogy of Fallot in early infancy because of the high mortality of direct aortopulmonary shunts. We believe the Blalock-Taussig anastomosis is a safe and effective palliative procedure for all infants with inadequate pulmonary blood flow regardless of size. During the past nine years, 24 babies less than 2 years old who were followed had construction of Blalock-Taussig anastomosis for inadequate pulmonary blood flow. There were no operative deaths and no shunt-related late deaths. Of the 24 babies, 12 were less than 12 months old. Eighteen of the 24 had tetralogy of Fallot. The remaining 6 had a variety of lesions with inadequate pulmonary blood flow. The mean weight of the entire group was 7.3 +/- 1.6 kg. Of those infants less than 12 months old, the mean weight was 6.8 +/- 2.0 kg. More than 6 months following construction of the shunt, 2 babies died from sepsis unrelated to cardiovascular status. All infants had adequate but not excessive pulmonary blood flow after shunting. There were no late shunt failures.
