Abstract

Purpose: to identify the onset site of the pharyngeal swallow response and correlate it with lesion topography in acute ischemic stroke (AIS).

Methods: an observational, cross-sectional, and prospective study involving 30 patients from a stroke unit, conducted in four phases: (1) dysphagia risk screening, (2) topographic analysis of brain lesions, (3) objective swallowing assessment, using videofluoroscopy, and (4) blinded analysis of videofluoroscopic exams by two speech-language pathologists. The onset of the pharyngeal swallow response was determined by using the Modified Barium Swallow Impairment Profile (MBSImP™), considering component 6. Statistical analysis included Spearman’s correlation, chi-square, and Cohen’s kappa tests (p < 0.05).

Results: the sample consisted of 13 (43.0%) females and 17 (57.0%) males, with a mean age of 69.1 ± 9.21 years. No correlation was found between the onset site of the pharyngeal swallow response and brain lesion topography.

Conclusion: the onset site of the pharyngeal swallow response did not correlate with the brain lesion topography in this population.

Resumo

Objetivo: identificar o local de início da resposta faríngea da deglutição e correlacionar com a topografia da lesão no Acidente Vascular Cerebral Isquêmico (AVCi) agudo.

Métodos: estudo observacional, transversal e prospectivo, envolvendo 30 pacientes de uma unidade de AVC. O estudo ocorreu em quatro fases: (1) avaliação do risco de disfagia; (2) análise topográfica das lesões cerebrais; (3) avaliação objetiva da deglutição por meio da videofluoroscopia; e (4) análise cega dos exames videofluoroscópicos por duas fonoaudiólogas.O início da resposta faríngea foi determinado pelo protocolo Modified Barium Swallow Impairment Profile (MBSImP TM ), considerando o componente 6. Para a análise estatística, utilizaram-se os testes de correlação de Spearman, qui-quadrado e Kappa de Cohen (p < 0,05).

Resultados: a amostra foi composta de 13 (43,0%) mulheres e 17 (57,0%) homens, com idade média de 69,1±9,21 anos. Não houve correlação entre o local de início da resposta faríngea e a topografia das lesões cerebrais.

Conclusão: não se observou correlação entre o local de início da resposta faríngea da deglutição e topografia da lesão encefálica.
