Summary of "Unlikely association between Kawasaki disease and intracranial aneurysms: a prospective cohort study."

OBJECTIVEKawasaki disease (KD) is a vasculitis that can cause aneurysm formation in coronary arteries and, more rarely, in peripheral arteries. A possible connection between KD and intracranial aneurysms is unclear. The purpose of this study was to determine if KD is associated with intracranial aneurysms.METHODSIn this prospective cohort study, all patients hospitalized and diagnosed with KD in the authors' hospital district area in the period from 1978 to 1995 were identified. Patients with a current age ≥ 25 years and a history of KD in childhood were included in the study, which was conducted between 2016 and 2017. Magnetic resonance angiography (MRA) of the brain was performed in all patients.RESULTSForty patients (25 males), whose mean age was 33.5 ± 3.9 years (mean ± standard deviation), were eligible for study inclusion. The mean age at KD diagnosis was 3.9 ± 3.1 years, and the mean follow-up was 29.5 ± 4.3 years. Six patients (15%) had coronary arterial lesions during the acute illness of KD. None of the patients (0%) had intracranial aneurysms on brain MRA, which is significantly under the prevalence of 10% (95% CI 0%-8.8%, p = 0.03) that is the recommended limit for intracranial aneurysm screening.CONCLUSIONSThe study results suggest that KD is not associated with an increased prevalence of intracranial aneurysms and that screening for intracranial aneurysms is not warranted in patients with a history of KD.

Medical and Biotech [MESH] Definitions

Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)

Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.

Bleeding within the SKULL that is caused by systemic HYPERTENSION, usually in association with INTRACRANIAL ARTERIOSCLEROSIS. Hypertensive hemorrhages are most frequent in the BASAL GANGLIA; CEREBELLUM; PONS; and THALAMUS; but may also involve the CEREBRAL CORTEX, subcortical white matter, and other brain structures.

A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.
