[Cerebral arteriovenous malformation (author's transl)].

Area of Science:

• Neurology
• Pediatrics
• Cardiology

Background:

• Congenital cerebral arteriovenous malformations (AVMs) are rare vascular anomalies.
• Early-onset congestive heart failure is a critical complication in neonates with AVMs.

Observation:

• Three neonates presented with immediate congestive heart failure.
• Clinical signs included scalp murmurs, cardiac murmurs, gallop rhythm, cardiomegaly, and hepatomegaly.
• Diagnosis was confirmed via carotid arteriography.

Findings:

• Two cases involved aneurysms of the great cerebral vein of Galen (vena cerebri interna Galeni).
• One case had an aneurysm in the sylvian artery distribution.
• Two patients died due to the non-feasibility of surgical intervention.
• One patient underwent successful resection of the AVM and is recovering well.

Implications:

• Early diagnosis and intervention are crucial for managing neonatal congestive heart failure secondary to AVMs.
• Surgical resection can be a viable treatment option for select cases.
• This highlights the severe hemodynamic impact of AVMs in the neonatal period.
