Tandem coarctation of the thoracic aorta with hypoplasia of the abdominal aorta.

After resection of the coarctation in a 3-year-old child with end-to-end anastomosis, a second membrane was found 1.5 cm lower. After a successful reoperation with an aortoplasty using Gore-Tex weak femoral pulses persisted. At catheterization, an area of irregular narrowing of the abdominal aorta just distal to the superior mesenteric artery was found with hypoplasia of the iliac and femoral arteries. In addition, this child had a two-sided cheilo-gnatho-palatoschisis, vesicoureteral reflux and absence of gall bladder and hepato-duodenal ligament. It is worthwhile considering that a second or third aortic abnormality can be hidden by a coarctation of the aorta.
