RESUMO
OBJECTIVE: The aims of the study were to (1) characterize the findings of flexible endoscopic evaluation of swallowing (FEES) in stroke patients undergoing mechanical thrombectomy (MT); (2) analyse the screening performance of the Standardized Swallowing Assessment (SSA); and (3) study the impact of FEES-defined dysphagia on 3-month outcomes. METHODS: This single-centre study was based on a local registry of consecutive acute ischaemic stroke patients undergoing MT during a 1-year period. Patients received FEES within 5 days of admission regardless of the result of dysphagia screening. We compared baseline demographic and clinical characteristics of patients with and without FEES-defined dysphagia. We collected 3-month modified Rankin Scale (mRS) and individual index values of the European Quality of Life 5 Dimensions (EQ-5D-iv). Using univariable and multivariable regression analyses we predicted 3-month outcomes for presence of dysphagia and for FEES-defined dysphagia severity. RESULTS: We included 137 patients with a median age of 74 years, 43.1% were female, median NIHSS was 12 and successful recanalization was achieved in 92.7%. Stroke-associated pneumonia occurred in 8% of patients. FEES-defined dysphagia occurred in 81% of patients. Sensitivity of the SSA as a dysphagia screening was 67%. Presence of dysphagia and increasing severity of dysphagia were independently associated with increasing 3-month mRS score. Increasing dysphagia severity dysphagia was independently associated with lower EQ-5D-iv. INTERPRETATION: Early FEES-defined dysphagia occurs in four in every five patients undergoing MT. SSA has a suboptimal dysphagia screening performance. Presence of dysphagia and increasing dysphagia severity predict worse functional outcome and worse health-related quality-of-life.
