Background: Abdominal aortic aneurysms are rare in children and are usually found in association with congenital cardiac or aortic malformations, connective tissue disorders, mycotic aneurysms, inflammatory arterial disorders, or trauma. Despite its rarity, early diagnosis and intervention are essential to prevent fatal complications.
Case: A 17-year old female adolescent presented at the Emergency Room with recurrent abdominal pain with radiation to the right flank area and vomiting for the past 2 weeks. Pertinent PE findings were systolic BP 130/98mmHg right upper extremity and 124/94mmHg on the left upper extremity and 176/124 on the right lower extremity and 162/122 on the left lower extremity and costovertebral angle tenderness on the right. Patient had a past history of essential hypertension and was only given Amlodipine and Losartan for a month. There were no blood pressure monitoring and follow-up consultations in their localilty. Computed tomography of the abdomen showed abdominal aortic aneurysm at the juxtarenal level. She was transferred to Philippine Heart Center and underwent abdominal aortic aneurysmorrhaphy and left renal artery re-implantation. Further, investigation was done to elucidate the ma etiology of aneurysm formation.
Conclusion: We report a case of abdominal aortic aneurysm in the pediatric age group. Most common causes are familial connective tissue and arterial inflammatory disorders. Prompt evaluation and management is needed to avoid fatal complications.
