Abstract:
Objective:To explore the characteristics of collateral circulation of moyamoya disease in CT angiography imaging.Methods: Data of 120 moyamoya disease patients diagnosed by the 94th hospital were collected. All the patients underwent CT angiography imaging and were divided into groups according to compensatory ways of collateral circulation. Lightspeed VCT was used in all patients to conduct CTA check, and assessed the clinical performance of 4 groups. Results: Group 1 consisted of 15 cases (12.5%) of ischemic type moyamoya disease. Group 2 had 53 cases (44.2%), 8 cases were ischemic type moyamoya disease, and 45 cases were beeding type group moyamoya disease. Group 3 had 38 cases (31.7%), who showed moyamoya vessel formation in the bottom of the brain, 7 of these cases were ischemic moyamoya disease, and 31 were bleeding type moyamoya disease. Group 4 had 14 cases (11.6%), all of whom belonged to bleeding type moyamoya disease, characterized by ophthalmic artery, temporal artery, middle meningeal artery, occipital artery communicating with terminal cortex intracranial vascular.Conclusion: Compensatory characteristics of collateral circulation vessels were closely correlated with the types of moyamoya disease.
