摘要
目的 深入探讨精索内静脉(ISV)反流的血流动力学变化及其检测方法。方法 应用彩色多普勒超声对287例精索静脉曲张患者进行检查。平卧位或站立位,Valsalva试验时,腹股沟内环处ISV至蔓状静脉丛连续出现反流为阳性。手术证实128例。结果 对腹股沟内环至睾丸上方的ISV血流状态进行检测,有助于区别生理性或病理性反流。Valsalva试验时的腹腔压力高低直接影响反流的程度。结论 股总静脉内径的变化可作为Valsalva试验有效腹压的参照标准。根据静脉的引流途径,ISV曲张可分为三种类型:回流型、分流型和瘀滞型目的 深入探讨精索内静脉(ISV)反流的血流动力学变化及其检测方法。方法 应用彩色多普勒超声对287例精索静脉曲张患者进行检查。平卧位或站立位,Valsalva试验时,腹股沟内环处ISV至蔓状静脉丛连续出现反流为阳性。手术证实128例。结果 对腹股沟内环至睾丸上方的ISV血流状态进行检测,有助于区别生理性或病理性反流。Valsalva试验时的腹腔压力高低直接影响反流的程度。结论 股总静脉内径的变化可作为Valsalva试验有效腹压的参照标准。根据静脉的引流途径,ISV曲张可分为三种类型:回流型。
Objective To study the hemodynamic change of varicocele and its detection method by color Doppler ultrasound(CDU).Methods 287 cases with varicocele were examined by CDU.The CDU study was interpreted as positive if the regurgitation through internal spermatic vein(ISV) in abdominal inguinal ring to pampiniform plexus was observed on Valsalva maneuver in the supine,and erect position.24 cases underwent venography and 128 cases were confirmed by surgery.Results The detection of hemodynamic change of IVS from abdominal inguinal ring to root of scroum was help to distinguish the physiological reflux from pathological.The blood volume of reflux was directly influenced by the intensity of intra abdominal pressure on Valsalva maneuver.Conclusions The diameter of common femoral vein can be used as a consulting standard of effective abdomal pressure on Valsalva maneuver.According to the route of venous drainage,varicocele is divided into three types:reflux type,shunt type and stagnation type.
