Evolution of treatment options for vein of Galen malformations: A review
Vein of Galen Malformations
Endovascular embolization has considerably improved outcomes in patients with VGAM. In the past, the prognosis for patients with VGAM was dismal, and successful procedures were considered to be those that partially or completely obliterated the lesion, but did not necessarily improve the patient's symptoms. More recently, with the continued development and improvement of endovascular techniques, many patients are found to be neurologically normal on follow-up, and mortality rates have dropped substantially when compared with microsurgical treatment.
