[Congenital abdominal infrarenal aortic aneurysm in infants: 2 case reports and literature review]

Abdominal aortic aneurysm is extremely rare in infant and is generally due to infection, umbilical artery catheterization, vasculitis, connective tissue diseases and tuberous sclerosis. At the absence of these evident causes, it is a congenital primary aortic aneurysm which is exceedingly rare and only a few cases have of which have been reported. Here we report two cases of aortic wall reconstruction done by a Gore tex patch. The immediate result is excellent with a reestablishment of the femoral pulse and an excellent Doppler control. The problem which we may face in the future is probably the aortic out come with this Gore tex patch a continaons follow up of these patients is necessary.

Use of Palmaz stents in a newborn with congenital aneurysms and coarctation of the abdominal aorta

Anomalies of the abdominal aorta are rare in the pediatric population limiting the reported knowledge base from which management decisions can be made. A 3-week-old male with congenital abdominal aortic coarctation and multiple aneurysms presented with malignant hypertension. We report the safe deployment of overlapping Palmaz stents using a 4-French catheter delivery system with significant relief of the coarctation gradient and restoration of adequate renal perfusion.

Congenital abdominal aortic aneurysm and renal dysplasia

We report a 6-month-old boy with abdominal aortic aneurysm and dysplastic kidneys. To the best of our knowledge, this is the first report of abdominal aortic aneurysm associated with dysplastic kidneys. Serial US, MR angiography and scintigraphy were performed. No underlying cause of the aneurysm was identified. Spontaneous thrombosis occurred within 2.5 years of diagnosis, but there was persistent renovascular hypertension and progressive deterioration of renal function.

Congenital abdominal aortic aneurysm: a case report

Abdominal aortic aneurysm (AAA) is distinctly uncommon in infants and children, and usually results from infection, iatrogenic trauma, vasculitis, connective tissue disorder, or tuberous sclerosis. Congenital "primary" neonatal AAA is exceedingly rare. The few reported cases of repair of congenital AAA describe use of synthetic graft material or aneurysmorrhaphy. We report the first successful treatment of a known 6 cm congenital infrarenal AAA repaired with a 5 mm cryopreserved allograft in a 4-month-old infant girl. The graft was pretreated with an antigen reduction process (SynerGraft), which preliminary studies suggest may inhibit allograft degeneration. The postoperative course was unremarkable. Lower extremity pulses and results of duplex ultrasound flow studies remained excellent at 14-month follow-up. Panel reactive antibodies against class I alloantigens remain negative. The use of an antigen-reduced allograft provides an acceptable conduit, which potentially may decrease allograft degeneration and relative graft stenosis associated with growth of the child, but requires follow-up.

Congenital abdominal aortic aneurysm causing renovascular hypertension, cardiomyopathy, and death in a 19-day-old neonate

A full-term baby girl who was sent home day of life 2 was admitted to the hospital on day of life 7 for respiratory distress and poor feeding. The child was found to be hypertensive and in heart failure. Further workup led to the diagnosis of a suprarenal abdominal aortic aneurysm, but the infant had deteriorated clinically with heart failure, modest renal failure, renovascular hypertension, and no operative cure. The child died on day of life 20. Early diagnosis and prompt surgical resection are essential to managing this rare and lethal condition.

Congenital abdominal aortic aneurysm in the infant: case report and review of the literature

Congenital abdominal aortic aneurysms are a distinct entity from acquired aortic aneurysms. The authors present the case of a 6-week-old boy with a 6-cm aneurysm involving the abdominal aorta and common iliac arteries. Three other cases of congenital aortic aneurysms are reviewed, and an approach to these rare patients is discussed. J Pediatr Surg 36:657-658.
