Balloon angioplasty of postoperative coarctation in the transverse arch in infants: protecting the common carotid artery.
We performed balloon angioplasty in three patients with postoperative coarctation in the transverse arch adjacent to the left common carotid artery. The age at arch reconstruction was 5, 6, and 2 days, while the interval between operation and balloon dilatation was 59 days, 87 days, and 12 months, respectively. Two balloons, one in the stenosis and the other in the left common carotid artery, were introduced over a wire sequentially and inflated simultaneously until the waist of the balloon in the arch disappeared. After balloon dilatation, a significant reduction in the peak-to-peak pressure gradient and an increase in vessel diameters were observed in all patients. Further growth of the transverse arch was documented at follow-up in two patients. No aneurysm has been detected in any patients. We believe that placing a protective balloon in the neck vessel increases safety during balloon dilatation of coarctation in the transverse arch.
