摘要
目的探讨多普勒超声测量睾丸包膜动脉血流动力学参数在评判外环下显微手术治疗精索静脉曲张疗效的价值.方法2011年12月至2012年4月我院共实施外环下显微手术治疗左侧精索静脉曲张手术32例,分别应用彩色多普勒超声测量患者术前及术后3个月、6个月的睾丸包膜动脉的血流动力学参数（收缩期峰值流速、舒张末期流速、阻力指数、搏动指数）.同时测量患者术前及术后6个月精液质量指标.结果术后不同时间与术前比较,左侧睾丸包膜动脉的收缩期峰值流速在术后下降（P〈0.05、P〈0.01）,舒张末期流速在术后明显增加（P〈0.05、P〈0.01）,阻力指数及搏动指数明显下降（P〈0.05、P〈0.01）.术后6个月精子的数量及活动力不同程度地提高（P〈0.01）,但精子质量指标与血流动力学参数间未发现相关关系（P〉0.05）.结论睾丸包膜动脉舒张末期血流速度的增加及包膜动脉阻力指数、搏动指数的下降提示术后睾丸组织内微循环的改善,这些参数可以较好地提示手术疗效.
Objective To investigate the value of testicular capsular artery blood flow parameters in judging the outcome of microsurgical subinguinal varicocelectomy. Methods Total of 32 patients with left varicocele who underwent microsurgical subinguinal varicocelectomy in our hospital from December 2011 to April 2012 were enrolled in the study all the patients were examined 3 times with color Doppler sonography（CDS） for testicular blood flow parameters（peak systolic velocity, end diastolic velocity, resistive index, and pulsatility index） before operation, and 3 months 6 months after operation respectively. The parameters were measured from capsular artery. Preoperative and postoperative semen parameters were also evaluated. Results Compared with that of preoperation,the mean values of blood flow velocities（peak systolic and end diastolic） decreased and increased respectively（P〈0.05, P〈0.01） in the left capsular artery, and resistance indices （resistive and pulsatility） decreased after surgery （P〈0.05, P〈0.01）. At 6th month after operation, sperm amount and motility all increased significantly （P〈0.01）. However, no significant correlation was found between sperm parameters and blood flow parameters（P〉0.05）. Conclusion The increase in blood flow velocity and decrease in resistive and pulsatility indices of the capsular artery may be indicators of an improvement in testicular microcirculation.Testicular blood flow parameters can be used for evaulating the outcome of microsurgical subinguinal varicocelectomy.
