宫外孕氨甲喋呤静脉途径保守治疗的超声监测价值

本文对１２例主要用氨甲喋呤（静脉点滴或推注，每日２０ｍｇ，连用５天）治疗的输卵管妊娠时行超声监测。使用东芝ＳＳＡ－２４０型超声诊断仪，探头频率是３．７５ＭＨｚ。按常规进行探查。１２例输卵管妊娠均经超声发现附件区的异位妊娠包块，最大径线２．１～４．７ｃ...

Venous Valvular Incompetence of Lower Extremity Assessed by CDFI Using Different Patient Positions and Evoking Reflux Methods

Objective:To explore the effect of CDFI with different patient positions and evoking reflux methods for diagnosing venous valvular incompetence(VVI).Methods:30 Lower limbs veins with chronic venous insufficiency were tested by Valsalva and limb compression maneuver in supine position,14 of 30 in addition of erect position.Results:The reflux times in supine or erect,Valsalva method were longer than that in limb compression maneuver,the velocities achieved the same results.Valsalva method is better for common femoral vein and great saphenous vein.Compression maneuver is more suitable for popliteal vein and superficial femoral vein,especially in erect position,erect was superior to supine.Valsalva combined with compression was better than single method.Valsalva combined with compression in supine position provided the sensitivity 94 6%,specificity 69 2% and accuracy 89 1%.This method can present sufficient clinical informations.It is more practical and more easy to perform for aged and debilitated patients.Conclusion:Valsalva combined with compression maneuver in supine position might be the first of choice for detect VVI.
