超声引导下腮腺导管生理盐水灌注诊断干燥综合征

目的探讨超声引导下腮腺导管注射生理盐水诊断干燥综合征(Sj gren′s syndrome,SS)的价值。方法对16例确诊的SS女性患者在超声实时监测下采用自制的磨去针尖的5.5号头皮针,沿腮腺导管开口插入腮腺主导管约2 cm,缓慢注入生理盐水2 mL左右,全程记录腮腺导管注水前后的宽度、光滑度、恢复时间、导管末端是否有生理盐水向组织渗漏等,与X线下泛影葡胺造影结果比较。结果SS患者超声引导下腮腺导管生理盐水灌注结果与X线下泛影葡胺造影结果相关性良好。结论超声引导下腮腺导管生理盐水灌注可以替代X线下泛影葡胺造影诊断SS。

Ultrasound-guided parotid duct's normal saline perfusion to diagnose Sj(o)gren's syndrome

Objective To detect the value of ultrasound-guided injecting normal saline into parotid duct to diagnose Sjgren′s syndrome(SS).Methods Sixteen diagnosed SS females,under an ultrasound real-time inspection,were slowly injected with some 2 mL of normal saline(NS) into their main parotid ducts(some 2 cm) by a self-made blunt scalp needle(size No.5.5) along the duct openings;a whole-coursed record was made for the parotid duct′s width,smoothness,recovery time,and whether NS leaking into tissue at the duct ends before and after theNSinjections,compared with those data from meglucamine diatrizoate X-ray contrast exams.Results A good concordance was found between the two above-mentioned methods.Conclusion Ultrasound-guided parotid duct′s NS perfusion can be used to diagnose SS as a substitute for X-ray contrast exam.
