The perforating artery first (arteria perforans prima) is a small artery that passes through the anterior part of the upper jaw and connects the internal carotid artery with the anterior cerebral artery. It is one of the important elements of the vascular system of the brain and plays an important role in the blood supply to the brain.
The perforating artery first passes through a canal called the Kisselbach-Fleischl canal, which is located between the upper jaw and the temporal bone. This canal contains many small vessels that provide blood supply to the teeth, gums and upper jaw.
When the perforating artery first reaches the anterior cerebral artery, it divides into two branches: the circumflex artery and the anterior cerebral artery. The circumflex artery runs around the internal carotid artery and provides blood supply to the brain. The anterior cerebral artery continues to the front of the brain and supplies the frontal lobes and other parts of the brain.
Dysfunction of the first perforating artery can lead to various brain diseases, such as stroke, cerebral hemorrhage and others. Therefore, it is important to monitor the condition of this artery and, if necessary, take preventive measures.
