Abstract

To evaluate the characteristics of cricopharyngeal dysfunction (CPD), the frequency, and correlation with a brain lesion in patients with first-ever ischemic stroke, and to provide basic data for developing a therapeutic protocol for dysphagia management. We retrospectively reviewed the medical records of a series of subjects post-stroke who underwent a videofluoroscopic swallowing study (VFSS) from January 2009 to December 2015. VFSS images were recorded on videotape and analyzed. CPD was defined as the retention of more than 25% of residue in the pyriform sinus after swallowing. The location of the brain lesion was assessed using magnetic resonance imaging. Among the 262 dysphagic patients with first-ever ischemic stroke, 15 (5.7%) showed CPD on the VFSS. Patients with an infratentorial lesion had a significantly higher proportion of CPD than those with a supratentorial lesion (p=0.003), and lateral medullary infarction was identified as the single independent predictor of CPD (multivariable analysis: odds ratio=19.417; confidence interval, 5.560-67.804; p<0.0001). Compared to patients without CPD, those with CPD had a significantly prolonged pharyngeal transit time, lower laryngeal elevation, and a higher pharyngeal constric...Continue Reading

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.
