Total correction for tetralogy of Fallot after Brock-type operation

We present a case of tetralogy of Fallot who had previously undergone a graded Brock-type operation. The post-operative development of pulmonary arteries and pulmonary trunk after the Brock operation were very suitable for total correction, which was then performed successfully. In contrast to shunt, in Brock-type operations enlargement of the outflow tract induces symmetrical growth of hypoplastic pulmonary arteries without the risk of acquired pulmonary obstruction or peripheral stenosis at the site of anastomosis. After palliative operations, the repair can be deferred until the pulmonary arteries are of a suitable size.
