Summary
One hundred-five patients (median age 14 months) in whom a PTFE prosthesis was used to create a systemic-pulmonary artery shunt were studied between 1978 and 1980. The prosthesis was mainly used to create a modified Blalock-Taussig anastomosis.
Nine patients died in hospital (8.5%, 70% confidence limits: 5.7% to 12.3%).
The clinical condition did not appear to be an incremental risk factor, while the young age and the underlying type of disease accounted for the hospital mortality to a large extent. All 96 survivals were available for follow-up information.
One graft, which was damaged intraoperatively, occluded 3 months later. The remaining patients have a patent graft 3 manths to 36 months (median 24 months) postoperatively.
In 6 patients the patency was assessed angiographically and no damages of the pulmonary artery were observed, therefore this type of palliation is advisable for any patient, particularly in the first year of life.
