    Abstract:
    BACKGROUND: The aim of this study was to evaluate the late results in adult patients who underwent surgery of the abdominal aorta as children. METHODS: During a 17-year period, eight children underwent surgery for lesions of the abdominal aorta. There were 6 boys and 2 girls, with an average age of 10 years. The presenting symptom that led to diagnosis of abdominal aortic lesions was hypertension in five cases and lower-limb claudication in three. The underlying disease was middle aortic syndrome in three cases, infrarenal aortic hypoplasia in two, infrarenal aortic aneurysm in two, and Takayasu's disease in one. Five children had associated renal artery lesions, including four with bilateral lesions and one with a unilateral lesion. Aortic bypass was used in all cases. A straight tube graft was placed between the distal descending thoracic or supraceliac aorta and the infrarenal aorta in six cases, and a bifurcated bypass was placed between the infrarenal aorta and the iliac arteries in two. Renal artery revascularization procedures (n = 9) included ex vivo repair with renal autotransplantation in five cases, direct reimplantation on the arch of Riolan in two, and direct reimplantation of the renal artery onto the aortic graft in two. RESULTS: One patient died on postoperative day 1. The remaining seven patients recovered uneventfully. Mean follow-up was 10.2 years. No patient was lost to follow-up. Further surgical intervention was required in three patients. The indications for additional surgery were fibrosis of a renal artery reimplanted onto the graft at 3 years, deterioration of the aortoaortic graft at 5 years, and false iliac aneurysm at 20 years. All seven patients had normal physical development. The average increase in height and weight were 28.5 cm and 26.2 kg, respectively. All patients had normal sexual function, and two are parents. All patients are currently asymptomatic. Short Form 36 scores for quality-of-life parameters were 78% to 83%. CONCLUSIONS: Late results of abdominal aortic surgery in children, in our experience, are encouraging. Quality of life in adulthood was excellent. Insofar as possible, correction should be deferred until the child is 8 to 10 years old so that a prosthesis of sufficient diameter can be used.
