Abstract
BACKGROUND AND INTRODUCTION
Interrupted aortic arch (IAA) is a very rare congenital anomaly carrying high neonatal mortality rate if left untreated. Rarer still, is its presentation in teenage or adulthood. This condition has been found to be complicated with cerebral aneurysms, which is a consequence of hemodynamic stress and hypertension secondary to arch interruption. Cerebral aneurysms can further complicate the clinical course and lead to poor clinical outcomes, especially if ruptured.
CLINICAL PRESENTATION
A 17-year-old female presented with ruptured basilar top aneurysm and was considered for endovascular coiling. Transfemoral access was chosen but the catheter could not be negotiated beyond proximal thoracic aorta. A computed tomographic angiography (CTA) of thorax and abdomen was performed, which showed isolated interruption of aortic arch. Subsequently, transradial route was used for coiling of the aneurysm.
CONCLUSION
To the best of our knowledge, the index case is one of the only seven cases of IAA with cerebral aneurysm that have been reported till date in medical literature. It also holds the unique distinction of being the first case of IAA with cerebral aneurysm treated by endovascular approach. Our case highlights the importance of transradial access in such pathological conditions.
