title: The significance of femoral pulses in coarctation of the aorta.
abstract: Between January 1974 and December 1981, 80 patients aged between 1 and 13 years underwent surgical correction of coarctation of the aorta. At pre-operative examination 45 patients had absent femoral pulses (group A) and 35 had palpable femoral pulses (group B). Nineteen patients were lost to late follow-up; the remaining 61 (76%) were followed up for between 3 months and 7 years. Of the patients in group A 89% had systolic and 87% diastolic hypertension, while in group B the respective figures were 80% and 77%. At follow-up after surgery, systolic hypertension was present in 36% of patients in group A and in 16% of those in group B. Diastolic hypertension was present in 73% of patients in group A but only in 19% of those in group B (P less than 0,0001). It would appear that children with coarctation of the aorta and absent femoral pulses are more likely to continue to have diastolic hypertension after surgical correction of the anomaly than are children in whom the femoral pulses are palpable. Early operation might reduce the incidence of hypertension in this group.
