Left internal carotid artery agenesis associated with communicating arteries anomalies. A case report.

Summary of "Left internal carotid artery agenesis associated with communicating arteries anomalies. A case report."

Agenesis, aplasia and hypoplasia of the internal carotid artery are rare congenital malformations. They are usually asymptomatic and incidentally discovered through ultrasound or imagistic tests. The aim of this study is to improve their management in our Departments. We report here the case of a 39-year-old woman addressed to our ambulatory in 2013 for benign symptoms like dizziness and headache. Imagistic findings (magnetic resonance imaging of the brain, and cervical spine, and magnetic resonance angiography of the head and neck) indicated a very rare condition: left internal carotid artery agenesis accompanied by the absence of the pre-communicant part of the left anterior cerebral artery and of the right posterior communicating artery. Internal carotid artery agenesis is an uncommon congenital anomaly and it could be misdiagnosed as stenosis/occlusion of this artery. This condition is important to be recognized due to the associated hemodynamic changes and in order to discover and evaluate other accompanying vascular malformations (aneurysms, collateral channels) and their life threatening potential risks (subarachnoid hemorrhage or ischemia). Also, it has a special importance in case of planning carotid or trans-sphenoidal hypophyseal surgery.

Medical and Biotech [MESH] Definitions

The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation.

The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.

Artery formed by the bifurcation of the internal carotid artery (CAROTID ARTERY, INTERNAL). Branches of the anterior cerebral artery supply the CAUDATE NUCLEUS; INTERNAL CAPSULE; PUTAMEN; SEPTAL NUCLEI; GYRUS CINGULI; and surfaces of the FRONTAL LOBE and PARIETAL LOBE.

Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION. (From Am J Forensic Med Pathol 1997, 18:251; J Trauma 1994, 37:473)

Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.
