Abstract
To identify the predictive variables for post-stroke dysphagia (PSD) among anterior circulation large vessel occlusion (LVO) stroke patients who underwent endovascular thrombectomy (EVT).This retrospective cohort study enrolled hospitalized patients with anterior LVO stroke who underwent EVT between January 1, 2018 and October 31, 2022. PSD was defined as the unsuccessful removal of the nasogastric (NG) tube. Factors, such as premorbid characteristics, laboratory results, EVT, rehabilitation-related parameters, and neuro-imaging, were analyzed for correlations to PSD at 4 and 12 weeks.The study enrolled 136 patients, with a mean age of 72.9 ± 13.0 years, and 59 patients (43.4%) were male. At 4 weeks, 47.1% of the patients needed an NG tube, and at 12 weeks, 16.2% still required an NG tube. We found that lower albumin, lower body mass index (BMI), higher initial and 24-h post-EVT National Institute of Health Stroke Scale (NIHSS) scores, stroke-associated pneumonia, poor initial sitting balance and ability to sit up, insula or frontal operculum lesions, and bilateral hemisphere involvement were all associated with PSD at both 4 and 12 weeks in the univariate logistic regression. Multivariate analysis revealed that significant predictors of unsuccessful NG tube removal at 4 weeks included lower BMI (adjusted OR [aOR] 0.73, p = 0.005), hemorrhagic transformation (aOR 4.01, p = 0.0335), higher NIHSS scores at 24 h post-EVT (aOR 1.13, p = 0.0288), poor initial sitting ability (aOR 0.52, p = 0.0231), insular cortex ischemia (aOR 7.26, p = 0.0056), and bilateral hemisphere involvement (aOR 41.19, p < 0.0001). At 12 weeks, lower BMI (aOR 0.78, p = 0.0098), poor initial sitting balance (aOR 0.57, p = 0.0287), insular cortex lesions (aOR 4.83, p = 0.0092), and bilateral hemisphere involvement (aOR 4.07, p = 0.0139) remained significant predictors.In patients with anterior LVO following EVT, PSD was associated with lower BMI, higher NIHSS scores, poor initial sitting balance and sitting ability, insular lesions, and bilateral hemisphere involvement.
