Role of the Trigeminal System on Posterior Communicating Artery Remodelization After Bilateral Common Carotid Artery Ligation

CONCLUSION: BCCAL may lead to important beneficial and hazardous histomorphological changes at the posterior communicating artery. The high neuron density of TGG may provide a beneficial effect by facilitating PComA enlargement via its vasodilatory properties for the increase of decreased cerebral circulation, although this situation may be hazardous for certain subjects with congenital or acquired cerebrovascular pathologies
