Endovascular Treatment of Vein of Galen Malformation in Kenya, East Africa

Vein of Galen aneurysmal malformations (VGAM) are arteriovenous fistulas between the choroidal or quadrigeminal arteries and the embryonic precursor of the vein of Galen – the median prosencephalic vein. VGAM represents 30% of arteriovenous malformations in the paediatric age group. They are associa...

description Vein of Galen aneurysmal malformations (VGAM) are arteriovenous fistulas between the choroidal or quadrigeminal arteries and the embryonic precursor of the vein of Galen – the median prosencephalic vein. VGAM represents 30% of arteriovenous malformations in the paediatric age group. They are associated with a high morbidity and 90% mortality if untreated but respond well to intervention with mortality reduced to below 40%. There are few documented cases of VGAM worldwide and scarce data about these lesions in sub-Saharan Africa with challenges in diagnosis and management. We present two cases of infants diagnosed with VGAM and treated with endovascular embolisation. We examine the clinical and radiological data at presentation, intervention and follow-up at one year. We report on some of the technical neuro-interventional details. Both patients had satisfactory radiological results and the interventions resulted notable clinical improvements from baseline. Physicians should maintain a high index of suspicion treating infants and toddlers presenting with macrocephaly, neurocognitive decline and cardiopulmonary symptoms. Upon diagnosis endovascular interventions are feasible and available.
