아급성 뇌졸중 환자의 비디오 투시 연하 검사 소견과 뇌병변 부위 및 임상적 요인들의 연관성

Objective: To investigate whether patterns of dysphagia were associated with the location of the brainlesion and clinical factors in subacute stroke patients. Method: One hundred and seventy-eight first-ever subacute stroke patients who underwentvideofluoroscopic swallowing study (VFSS) from January 2006 to April 2012 were enrolled in the presentstudy. Swallowing-related parameters were assessed by VFSS. The location of brain lesions wereclassified into the cortical, subcortical, and brain stem. The degree of cognitive impairment and theindependency of activities of daily living were assessed by the Korean version of mini-mental statusexamination and Korean version of modified Barthel index (K-MBI). Aphasia and hemineglect wereassessed by Korean version of Western aphasia battery and line bisection test. These data werecollected via retrospective chart review. Results: A reduced laryngeal elevation and prolonged pharyngeal delay time were associated with brainstem lesion. Other swallowing parameters were not associated with lesion topology. Pyriform sinusresidue was associated with the presence of aphasia and low K-MBI scores. Prolonged pharyngealdelay time was associated with the patient's age, type of stroke and brain stem lesion. Conclusion: Pyriform sinus residue was associated with clinical factors such as aphasia and K-MBIscores rather than with the location of brain lesion. However, reduced laryngeal elevation and prolongedpharyngeal delay time were predominant in brain stem lesions. KCI Citation Count: 3
