Title: Extracranial and intracranial angiographic changes in patients subjected to cervical internal carotid stenting


Background: Stroke is the third most common cause of mortality. About 25% of cases are caused by carotid atherosclerotic diseases.

Objective: To explore and analyze the extra cranial and intracranial angiographic changes of the internal carotid artery like stenosis, prolonged circulation time, degree of dilatation and associated pathological changes like elongation, kink and tortuosity inpatients subjected to cervical internal carotid artery stenting.

Patients and Methods: The study was a prospective study that conducted on 13 patients with high-grade asymptomatic or symptomatic carotid artery stenosis who were scheduled to undergo carotid artery stenting. The patients were recruited from Neurosurgery department, AlAzhar University and Ministry of Health hospitals during the period from august 2019 to December 2020.

Results: 69.2% of cases had no intracranial finding, 15.4% of cases had MCA & ACA attenuation with collaterals opening. 15.4% of cases had ICA stenosis at petrous bone. Diameter of stent increased much 2.7 times in cases without hypertension more than cases with hypertension.

Conclusion: Majority of cases of internal carotid artery stenosis have no intracranial attenuation. Hypertension affected the degree of post stenting dilatation and subsequently, the circulation time.
