RESUMO
Objective To analyze the clinical features of obstructive sleep apnea-hypopnea syndrome(OSAHS)with initial diagnosis of aorta dissection(AD)and therefore to improve its diagnosis.Methods The clinical data of 6 cases of AD with OSAHS were retrospectively analyzed.Results There were six male cases of obesity whose average body mass index(BMI)was 32.72±3.57,with an average age of(43.83±2.14)and the leading symptoms were daytime hypersomnolence,nocturnal wake by suffocation and habitual snoring.ESS was(13.83±2.14),apnea hypopnea index(AHI)was≥62/h[on averaga of(73.35±9.16)/h],the lowest pulse oxygen saturation(LSpO2%)was(58.67±10.95)%,time of oxygen saturation level lower than 90%(min)[T90(min)]was(244.20±144.74)min,the percent of the total time with oxygen saturation level lower than 90%(TS90%)was 54.48±30.18.They had more than two years history of hypertension.Conclusion Severe OSAHS affects the prognosis of AD.Early diagnosis and timely treatment can delay the progress of AD and lower death rate,with an important significance in improving the prognosis of AD.
