Ultrasound has been gradually applied to the field of cerebral small vessel disease (CSVD) due to its unique advantages. This paper summarized the studies related to ultrasound in CSVD, and summarized the relationship between CSVD and various evaluation indicators of vascular ultrasound. What’s more, this paper described the role of ultrasound in the evaluation and diagnosis of multi-system diseases such as heart, brain, and kidney coexisting with CSVD, and provided a theoretical basis for comprehensive and effective evaluation of CSVD by ultrasound.

Persistent artery is an abnormal anastomotic branch between the permanent internal carotid artery and the vertebrobasilar artery, which is a rare cerebrovascular variation. Typically, persistent arteries have a blood supply function and do not cause specific clinical symptoms; however, when accompanied by atherosclerotic lesions of the arteries and other vascular variants, they result in a complex clinical presentation. At present, ultrasonography is the first choice for clinical evaluation of cerebral and cervical vascular abnormalities. Correct diagnosis of persistent arteries improves clinical interpretation and reduces the risk of improper operation during related surgical or interventional procedures. Most persistent arteries are discovered incidentally through imaging, and their imaging manifestations are characteristic. There are many reports on the imaging diagnosis of persistent arteries at home and abroad, but few on ultrasonography staging and hemodynamics. Based on the literature, this paper innovatively proposed an ultrasound diagnostic concept and staging of the persistent artery in an effort to improve the early and accurate diagnosis of the persistent artery.
