Anatomical repair of a congenital aneurysm of the distal abdominal aorta in a newborn

Abstract

Congenital (primary) neonatal abdominal aortic aneurysm (AAA) is an extremely rare truncular arterial abnormality among numerous congenital vascular malformations. Only seven cases have been reported as congenital origin in newborns. This report presents the case of a male infant in whom a 33-mm congenital AAA was diagnosed prenatally and was successfully treated 10 days after birth without exogenous graft material or aneurysmorrhaphy. Follow-up study at 39 months demonstrated excellent clinical, ultrasound scan, and computed tomography scan findings. Anatomic reconstruction with native vessels is the preferred surgical technique to ensure the child's potential for harmonious growth.

Surgical repair of congenital abdominal aortic aneurysm in a 1-year-old child with literature review

“…[7] Although there has not been any study comparing individual surgical approaches in CAAA, aneurysmorrhaphy has been found to have higher recurrence rate. [8] Among the 26 cases reported so far, surgical correction could not be done in 11 (42%) patients due to late presentation, extensive involvement, renal dysfunction, or rupture of aneurysm during exploration. Of these 11, six either died in theater or in early follow-up after surgery (<1 month).…”

Diagnosis and treatment of congenital abdominal aortic aneurysm: a systematic review of reported cases

“…In the present review, reconstruction of AAA was achieved using native vessels without exogenous material in a 10-day-old boy [ 23 ]. This method was feasible, allowed natural vessel growth, and avoided graft-related complications.…”

Mycotic Saccular Abdominal Aortic Aneurysm in an Infant after Cardiac Catheterization: A Case Report

“…Some authors have advocated against the use of cryopreserved human allografts in children given their lack of growth potential and propensity to evoke an immune reaction with subsequent fibrosis, degradation, and propensity for aneurysm formation as chief concerns. 20 Adult data have demonstrated, however, that use of cryopreserved human allografts in the setting of infection carries similar mortality risk and serves as a functional alternative to vascular reconstruction in patients without adequate autogenous conduit 21 dof which children would be a prime example. Others have also recommended use of cryopreserved vascular conduits in children under 6 years of age because of anatomic limitations on vessel size.…”
