[Aortic arch interruption and cutaneous PO2].
In three neonates with cardiac failure and coarctation the cutaneous PO2 (cPO2) has been measured during the administration of a high concentration of oxygen. One sensor was fitted to the skin just below the right clavicle (preductal) and the other on one of the legs (postductal). The difference in the cPO2 provided evidence for a large right to left shunt through the duct. This finding in conjunction with the clinical syndrome of co-arctation is characteristic, in our view, of atresia of the aortic arch. The results of the test, with clinical and echocardiographic details enable more accurate decisions to be made before catheterisation and surgery.
