Systemic-pulmonary artery shunts remain an important treatment in cyanotic
patients. Central shunts continue to pose early and late problems when
standard Blalock-Taussig shunts are not possible. Twenty patients underwent
subclavian-pulmonary artery shunt procedures with polytetrafluoroethylene
(PTFE) prostheses between October, 1980, and August, 1982. Their ages
ranged from 1 day to 15 years; 11 patients were less than 14 days old. The
arterial oxygen tension rose from 30.7 +/- 11.9 mm Hg to 51.3 +/- 9.1 mm Hg
(standard deviation; p less than 0.001) and from 26.4 +/- 7.5 mm Hg to 50.5
+/- 9.3 mm Hg (p less than 0.001) among the 11 neonates. There were no
hospital deaths and only 2 late deaths (not shunt related). All patients
have patent shunts and excellent relief of cyanosis. The 18 survivors have
been followed for an average of 19 months (range, 7 to 29 months). No
patient has required reoperation for shunt inadequacy or thrombosis.
Recatheterization in 11 patients has demonstrated normal pulmonary
pressures and good pulmonary artery growth without vessel distortion.
Subclavian-pulmonary shunts using PTFE provide long-term palliation in
cyanotic patients. This type of shunt appears to offer important advantages
over other shunt procedures, including the classic Blalock- Taussig
operation, in newborns.
