Background
Congenital abdominal aortic aneurysm (AAA) is a rare condition in neonates. To our knowledge, the natural course of the disease in a Thai neonate has not yet been reported.
Objectives
To report the characteristics and clinical course of congenital AAA in a Thai neonate.
Methods
A female Thai infant was born spontaneously at term (3,990 g) having a large, pulsatile, abdominal mass. Computed tomographic angiography (CTA) of the abdominal aorta showed a large infrarenal AAA, and a fusiform aneurysm at the left common iliac artery. Two small right renal arterial aneurysms were also noted. The large aneurysm was partially resected and a Gore-Tex vascular graft was placed at 15 days old. Histopathology of the aneurysmal wall revealed no specific etiology. Ultrasonography revealed thrombosis of the graft on the 13th day after surgery.
Results
Repeated CTA of the abdominal aorta at age 13 mo showed complete thrombosis of the graft with reconstitution of collateral circulation. The infrarenal AAA and left common iliac aneurysm and 2 small right renal artery aneurysms were completely thrombosed. The patient grew and developed normally to the most recent follow up at age 36 mo.
Conclusions
Congenital AAA with failure of graft replacement may regress spontaneously.
