双源CT上气道检查联合多导睡眠监测在阻塞型睡眠呼吸暂停低通气综合征诊断中的应用价值
Application of dual-source CT airway examination combined with polysomnography in diagnosis of obstructive sleep apnea syndrome
摘要
Abstract
Objective:To investigate the diagnostic efficacy of dual-source CT airway examination combined with polysomnography(PSG)in obstructive sleep apnea syndrome(OSAS)and analyze the correlation between the two methods.Methods:A retrospective analysis was conducted on 120 patients suspected of OSAS.PSG results were used as the gold standard,and based on apnea-hypopnea index(AHI),120 patients were divided into the non-OSAS group(11 cases),mild OSAS group(35 cases),moderate OSAS group(43 cases),and severe OSAS group(31 cases).The diagnostic efficacy of dual-source CT airway examination for OSAS was analyzed based on PSG results,and the dual-source CT airway examination parameters and PSG parameters were compared among different groups.Spearman correlation analysis was conducted.Results:The diagnostic accuracy of dual-source CT for OSAS was 93.33%(112/120),with a sensitivity of 94.50%(103/109),a specificity of 81.82%(9/11),a positive predictive value of 98.10%(103/105),a negative predictive value of 60.00%(9/15),which was moderately consistent with the PSG results(K=0.656).PSG results showed that as the severity of OSAS increased,the patients'blood oxygen saturation(SpO2)decreased,and apnea duration increased(both P＜0.001).Dual-source CT showed significant differences in minimum airway cross-sectional area,airway volume,soft palate collapse rate and tongue base collapse rate among different OSAS severity levels(all P＜0.001).As the severity increased,the minimum airway cross-sectional area and airway volume decreased,while the soft palate and tongue base collapse rates increased.Spearman correlation analysis revealed that the minimum airway cross-sectional area and airway volume on dual-source CT were negatively correlated with AHI and apnea duration and positively correlated with SpO2(all P＜0.001).The soft palate and tongue base collapse rates were positively correlated with AHI and apnea duration and negatively correlated with SpO2(all P＜0.001).Conclusion:Dual-source CT airway examination combined with PSG can more comprehensively assess the anatomical structure of the upper airway and respiratory function,providing a more precise basis for the clinical diagnosis of OSAS.关键词
