Carotid artery dissection (CAD) is a rare cause of ischemic stroke, and its prognosis is often poor.If not diagnosed and treated in time, it may lead to serious complications such as intracranial stroke and even death. Accurate diagnosis of CAD, formulation of reasonable treatment plans, and prediction of vascular recanalization are crucial for improving the prognosis of patients.However, there is currently a lack of large-scale randomized controlled trials to provide guidance for clinical practice, and the industry has not yet reached a unified consensus on the standardized diagnosis and treatment of CAD. Therefore, this article reviews the imaging examination methods for recanalization of CAD, the analysis of related factors affecting recanalization, and the methods of recanalization treatment, and combines the latest research progress to provide a perspective on the recanalization of carotid artery dissection, aiming to provide a reference basis for the precise diagnosis and treatment of CAD recanalization.respectively [6]. This disease is characterized by high mortality, high disability rate, and high recurrence rate, making it a significant public health issue threatening the health of the nation.Current research indicates that the majority of CAD cases are spontaneous, but it is worth noting that approximately 90% of traumatic dissections are caused by minor trauma, including neck massage, weightlifting, yoga, childbirth, and other daily activities [7]. Additionally, multiple studies have identified various potential risk factors, such as recent infection, pregnancy status, oral contraceptive use, smoking history, migraine, elongated styloid process, vascular anatomical variations, and genetic susceptibility [5,[8][9][10]. Interestingly, recent studies have even found an association between higher education levels and CAD-related ischemic stroke in young people [11]. However, the relationship between these factors and vascular recanalization after CAD remains to be further confirmed. In clinical practice, due to the relative rarity of CAD, the existing evidence mainly comes from case reports and case series studies, lacking the support of largescale randomized controlled trials, which has led to the absence of a unified consensus on diagnosis and treatment at the international level [7]. With the rapid development of modern
