Abstract:
Objective:To analyze the clinical and radiological features of patients with hypoplasia of the internal carotid artery.Methods:Four patients with hypoplasia of the internal carotid artery (including 3 patients with congenital absence of the internal carotid artery), admitted to our hospital from January 2010 to December 2021, were chosen in our study. The clinical data and imaging features of these patients were retrospectively analyzed.Results:The age of these patients ranged from 31 to 73 years, and two patients were female. Clinically,2 patients presented with dizziness, 1 patient presented with limb weakness, and 1 patient was asymptomatic. In 3 patients with congenital absence of the internal carotid artery, DSA results showed that the internal carotid artery was not developed, and CT bone window showed that the internal carotid artery canal was absent; 1 patient with hypoplasia of the internal carotid artery showed thin imaging in DSA results. One patient was combined with anterior communicating artery aneurysm and left internal carotid artery aneurysm. One patient was with vertebral arterial dolichoectasia. The collateral circulation compensation: type A was noted in 3 patients and type C was noted in 1 patient.Conclusion:The patients with hypoplasia of the internal carotid artery are usually asymptomatic, and patients with congenital absence of the internal carotid artery can have ischemic symptom; these patients can be complicated with vascular abnormalities such as aneurysm and vascular thickening.
