摘要 目的探讨超声造影剂(USCA)观察小腿急性下肢深静脉血栓(DVT)形成后股总静脉造影剂微泡灌注特征及时间-强度曲线(TIC)变化规律与股总静脉血流动力学变化的关系。方法选取小腿急性DVT形成患者15例作为研究组,行经肘静脉超声造影,分析双侧股总静脉造影剂微泡灌注特征及TIC特点,并设立对照组12例。检测参数包括双侧股总静脉造影剂微泡出现时间、达峰值时间、峰值强度及达峰值后造影剂微泡与静脉管壁间低回声带宽度。结果研究组患侧造影剂出现时间及达峰时间为(56.76±11.24)s、(61.43±7.12)s,健侧造影剂出现时间及达峰时间为(42.46±7.28)s、(51.57±5.79)s,双侧比较差异有统计学意义(P<0.05);研究组患侧低回声带宽度为(0.31±0.08)cm,健侧为(0.09±0.03)cm,二者差异有统计学意义(P<0.05),余参数比较差异无统计学意义(P>0.05);对照组双侧各参数比较差异无统计学意义(P>0.05)。结论经肘静脉超声造影可显示双侧股总静脉微泡灌注情况,间接判断脑卒中后有无急性小腿DVT形成,即造影后发现一侧股总静脉的微泡灌注出现时间及达峰值时间较对侧明显延长、低回声带较对侧明显增宽则高度提示该侧小腿DVT形成。
