Spontaneous Thrombosis in Giant Aneurysm of the Anterior Communicating Artery Complex in Pediatric Age: Five-Year Follow-Up

Abstract EN

Intracranial aneurysms are rare in the pediatric population, especially in infancy, representing less than 1% of all aneurysms.

In this age group, they are more frequent at the carotid bifurcation and in the posterior circulation, with a greater number of giant aneurysms and spontaneous aneurysm thrombosis when compared with the adults.

They are life-threatening, and, therefore, early investigation, characterization of the lesion, and treatment are essential.

The appropriate management depends on the child’s condition, aneurysm characteristics, and the experience of a multidisciplinary team.

Noninvasive and radiation-free imagiological studies play an important role in the diagnosis and follow-up of these young patients.

We present the case of a 3-month-old boy with an intracranial hemorrhage secondary to the rupture of a giant aneurysm of the anterior communicating artery complex, with spontaneous thrombosis, which is a rare situation due to its location.

A conservative approach was assumed and noninvasive evolutive imagiological studies revealed a reduction in the thrombosed aneurysm size and no signs of recanalization.

The child recovered to his baseline neurological condition and has had no rehemorrhage until 5 years of follow-up.
