Tandem coarctation of the thoracic aorta. An unusual congenital anomaly
U Hvass, J Langlois, P Robinson and PE Valere
The coarctation involving the aortic isthmus, with hypoplasia of the upper
aortic segment, was satisfactorily repaired in a 15-year-old girl. The
technique used was subclavian flap arterioplasty followed by reimplantation
of the distal subclavian artery into the left carotid artery. Suprisingly
weak femoral pulses were noted postoperatively and prompted a control
angiogram. This showed an intraluminal diaphragm 2 cm below the site of the
previous repair, with a 100 mm Hg gradient. At reoperation, a centrally
performed fibrous diaphragm was excised, and the aorta was enlarged with a
small Dacron patch. The postoperative course was uneventful.
