阻塞性睡眠呼吸暂停低通气患者舌动脉CT成像测量及其意义

目的探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者间舌动脉CT血管成像(CTA)特点,为临床中线舌部分切除手术提供参考。方法对93例OSAHS患者进行舌咽区上呼吸道CT扫描和舌动脉CTA成像测量,比较不同舌腭关系分型的OSAHS患者组各项测量参数的差异。结果 4组不同舌腭关系分型的OSAHS患者间年龄、AHI、LSaO2和舌宽无明显差别,但BMI、舌后区呼吸道截面积、舌宽、舌长和舌厚度存在明显差别。4组间舌动脉长度(mm)分别为93.6±15.84、95.9±16.39、99.6±15.19、110.0±12.16;舌盲孔区舌动脉深度(mm)分别为27.4±5.81、27.3±4.28、28.0±4.43、31.2±6.38;舌动脉间距(mm)分别为21.7±3.57、23.1±4.90、22.8±5.53、25.6±4.60,组间差异均显著。舌动脉深度和间距分别与舌厚和舌宽显著相关。结论不同舌腭关系分型的OSAHS患者间舌动脉走行和测量参数存在明显差别,差别的原因与舌体肥厚等解剖改变有关。

Lingual arterial CT angiography and its clinic significance for patients of the obsturctive sleep apnea hypopnea syndrome

Objective　To explore imaging features of lingual arterial CT angiography (CTA) among patients of obstructive sleep apnea hypopnea syndrome (OSAHS) with different lingua-palate position types. Methods: Ninety-three patients with OSAHS were included in the study and the lingual upper airway CT and lingual arterial CTA were obtained. The CT data among 4 groups of patients with different lingua-palate position types were compared.　Results　 There were no difference in the ages, AHI and LSaO2 among 4 groups of patients, however, the difference appeared in the BMI, area of lingual airway, length and thickness of lingua. For 4 groups, the length of lingual artery(mm) were 93.6±15.84, 95.9±16.39, 99.6±15.19 and 110.0±12.16, respectively, and the depth(mm) at the site of lacuna of tongue 27.4±5.81, 27.3±4.28, 28.0±4.43 and 31.2±6.38, respectively. The distance between bilateral lingual arteries (mm)  were 21.7±3.57, 23.1±4.90, 22.8±5.53, and 25.6±4.60，respectively, with the significant difference. There were correlation between the depth of lingual artery and lingual thickness, as well the distance of bilateral lingual arteries and the lingual width.　Conclusions　For OSAHS patients, the courses of lingual artery and imaging data are different, which maybe concerned with the anatomic features of tongue.
