Vein of Galen Aneurysmal Malformation with Transvenous Endovascular Treatment in an Adult: Case Report

AbstractVein of Galen aneurysmal malformation (VGAM) is the result of the direct communication between the arterial network and the median prosencephalic vein. It is a rare vascular congenital malformation representing less than 1% of intracranial abnormalities. This finding is very rare in adults, and it may or may not present symptoms during childhood. Most cases of VGAM can be detected in the fetus by ultrasonography. The referral of pregnant women with fetuses with this condition to centers where better facilities and resources for childbirth and immediate postpartum care are available has resulted in considerable improvement in the prognosis of newborns. Regarding treatment, the endovascular approach to VGAM includes arterial embolization and percutaneous transvenous techniques. The transvenous endovascular treatment was chosen in the case presented in this article.

Vein Of Galen Aneurysm

Vein of Galen aneurysm is a rare pathology, representing less than 1% of intracranial vascular malformations. We report on a 65 years-old man who experienced a generalized tonic-clonic seizure. Brain imaging showed a large calcified expanding mass in the pineal region, confirming the diagnosis of a vein of Galen aneurysm. Because of the spontaneous thrombosis of the malformation, there was no need for microsurgical or endovascular treatment and he is been regularly followed since that.

Rapid Ventricular Pacing

The treatment of choice of vein of Galen aneurysmal malformation (VGAM) involves endovascular procedures that can be difficult to perform in high-flow fistulas. We describe the use of rapid ventricular pacing (RVP), a well-known cardiologic technique, to safely treat a high-flow fistula in an infant with VGAM.

Direct Communication

Arteriovenous malformation (AVM) is a common form of vascular malformation, an abnormal direct communication between an artery and a vein without passing through the capillaries. AVM may just present as hematuria without plain or other symptoms. The article presents a case of a 52-year-old male with gross hematuria diagnosed as AVM of internal pudendal artery, which was successfully managed with superselective arterial embolization using temporary embolization materials.

Purpose Arteriovenous fistulas of the Vein of Galen region in adults (Ad-VGAVF) are an uncommon entity with specific anatomic features. The aim of this article is to present our experience in the endovascular treatment of this pathology and to propose a therapeutic strategy based precisely on the angioarchitecture of these lesions. Materials and methods During a 20-year period, 10 patients underwent endovascular treatment of Ad-VGAVF. They were nine men and one woman with a mean age of 50 years (23–66 years) treated with the same embolization strategy. Clinical presentation, angiographic characteristics, therapeutic strategy, and clinical outcomes were recorded. Results All patients were treated exclusively by endovascular approach. Transarterial access was performed in eight patients and combined transvenous and transarterial access in two. Complete obliteration of the fistula was obtained in all patients. There were no intraprocedural complications. Post-embolization neurological symptoms occurred in 5 of 10 with complete resolution at six months in all of them. Conclusion Arteriovenous fistulas of the Vein of Galen region in adults present uniform angioarchitecture despite their low prevalence. Based on this constant angioarchitecture and especially on the features of its venous drainage, judicious embolization strategy is feasible and effective. Ten cases treated entirely by endovascular approach with excellent clinical and angiographic outcomes show this treatment like a curative alternative for this entity of deep topography and severe prognosis.
