Spanish to English Medical Medical (general) carotid stent-angioplasty

Here's the only time this term occurs in the document:

Basados en una idea original de J.C. Parodi, se valen de las conexiones del polígono de Willis y la presión retrógrada generada al ocluir la ACC y la AGE.

The ACC is the common carotid artery in English (CCA), but I can't figure out AGE. My impression is that perhaps it's a typo for Arteria Carótida Externa (ACE), but that's just a guess.

Any help would be greatly appreciated.
