ObjectiveTo systematically review the association between migraine and lacunar infarcts on MR image.MethodsPubMed, EMbase, The Cochrane Library, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials, cohort studies and cross-sectional studies on the association between migraine and lacunar infarcts from inception to March 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 5 studies involving 5 104 participants were included. The results of meta-analysis showed that: there were no significant associations of migraine (OR=0.93, 95%CI 0.78 to 1.12, P=0.470) and aura (OR=1.10, 95%CI 0.89 to 1.36, P=0.390) with lacunar infarcts on MR image. Subgroup analysis by age, presence or absence of aura showed no significant tendency.ConclusionsThere is no significant relationship between migraine and lacunar infarcts. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Ischemic lesions, lacunar infarcts and leukoaraiosis on head CT or MRI are commonly detected in patients with non-specific symptoms such as dizziness and headache or people undergoing healthy physical examinations. Although these imaging findings are mostly related to vascular disease, especially cerebral small vessel disease, it does not mean that long-term use of antiplatelet drugs and statins are required. On the basis of literature review and clinical experiences, the article points out that the treatment methods for such manifestations include determining whether these lesions are vascular lesions, searching for risk factors or causes such as aging, hypertension, diabetes mellitus, vascular stenosis, and psychological factors, and taking strategies for the corresponding prevention and management, provides a reference for the appropriate diagnosis and treatment of these imaging manifestations in clinical practice.
