Abstract:
Objective To investigate the imaging characteristics and main clinical manifestations of patients with respiratory and/or cardiac arrest after medullary infarction (MI).Methods The study included patients with respiratory and/or cardiac arrest after MI,who were hospitalized in the Department of Neurology of Huanhu hospital between 2016 and 2021.The patients were divided into groups and analyzed according to the infarct location and infarct size shown by MRI-DWI,the degree of vascular stenosis shown by MRA and the main clinical manifestations.Results The study enrolled a total of 28 patients, including 19 patients with lateral medullary infarction (LMI) and 9 patients with medial medullary infarction (MMI).For LMI patients,from head to tail,there were 4 cases with upper MI,11 cases with middle MI,and 4 cases with lower MI.On the axial plane,there were 4 cases in the middle,14 cases in the dorsal,and 1 case through the middle and dorsal.Among the 28 patients,50% were large area MI (DWI high signal≥1/3 of the total area of medulla oblongata) and medium area MI (1/4 of the total area of medulla oblongata≤DWI high signal<1/3 of the total area of medulla oblongata).Sixteen cases completed brain MRA examination,of which 12 cases were moderate and severe vascular stenosis.Among the 28 patients,16 cases were complicated with infarction in other parts,of which 9 cases were complicated with cerebellar infarction.The main clinical symptoms were dizziness and dysarthria.For the 19 LMI patients,dizziness was the main complaint in 16,dysarthria in 16,dysphagia in 10,limb weakness in 7.For the 9 MMI patients,dizziness was the main complaint in 6,dysarthria in 8,dysphagia in 3,limb weakness in 7.Conclusion LMI is the main type of respiratory and/or cardiac arrest after MI,and it is more common in patients with dorsal medulla oblongata in the middle part.The proportion of patients with medium and large area MI is relatively high.Most patients have moderate and severe vascular stenosis and often complicated with cerebellar infarction.The main complaints were dizziness and dysarthria.LMI was more prone to dysphagia and MMI to limb weakness.
