Trans-mesencephalic arteries and veins. Angiographic aspects in tectal vascular lesions.
The authors present the trans-mesencephalic arteries and their rôle in the differentiation of pure and secondary vein of Galen arterio-venous malformations (AVM). They illustrate the trans-mesencephalic draining veins of the so-called venous angiomas, which are normal variants, often associated with cavernous haemangiomas representing the clinically active lesion.
