简介：【摘要】目的 探讨经腹部与经阴道彩色多普勒超声诊断早期异位妊娠的临床应用价值。方法 选取 2019年 3月～ 2020年 3月期间我院收治的早期异位妊娠患者参与研究调查，并抽取其中的 60例按照随机数字表法 分为两组--对照组 和观察组，均为30例。以手术病理结果作为金标准，其中选用经腹部彩色多普勒超声的设为对照组，而选用经阴道彩色多普勒超声的设为观察组，分析讨论两组的诊断结果。结果 观察组的检出准确率高于对照组，差异有统计学意义（ p＜ 0.05）。观察组的胎心、盆腔积液等超声影像学的检出阳性率均高于对照组，差异有统计学意义（ p＜ 0.05）。结论 早期异位妊娠应用经阴道彩色多普勒超声检查，可大幅度提升患者的检出准确率，降低漏诊例数，可较经腹部彩色多普勒超声更早发现异位妊娠，值得推行。

简介：　　 [摘要 ] 目的 探讨分析彩超用于早期诊断糖尿病患者下肢血管病变的临床价值。方法 随机选取 2018年 12月— 2019年 12月期间该院收治的糖尿病患者 45例和非糖尿病患者 45例作为研究对象，将 45例糖尿病患者分为观察组， 45例非糖尿病患者分为对照组，对所有研究对象进行彩色多普勒超声检查，观察比较两组的检查结果。结果 观察组患者中有 34例（ 75.56%）出现动脉粥样硬化，有 35例（ 77.78%）出现动脉斑块，有 33例（ 73.33%）患者出现管腔狭窄或者闭塞；对照组患者中有 4例（ 8.89%）出现动脉粥样硬化，有 12例（ 26.67%）出现动脉斑块，有 8例（ 17.78%）患者出现管腔狭窄或者闭塞，观察组患者的动脉粥样硬化、动脉斑块以及管腔狭窄或者闭塞发生率明显高于对照组；观察组患者的血管动脉血流速为（ 35.12±3.27） cm/s、血流量为（ 27.84±9.18） mL/min；对照组患者的血管动脉血流速为（ 44.58±3.93） cm/s、血流量为（ 45.67±10.34） mL/min，观察组患者的血管动脉血流速与血流量明显低于对照组，差异有统计学意义（ P<0.05）。结论 综上所述，彩超在糖尿病患者下肢血管病变的早期诊断中临床价值较高，检出率高，值得推广。  　　 [关键词 ] 彩超：早期诊断糖尿病；下肢血管病变；临床价值  　 [Abstract] Objective To explore the clinical value of color Doppler ultrasound in the early diagnosis of diabetic patients with lower extremity vascular disease. Methods 45 cases of diabetic patients and 45 cases of non-diabetic patients in our hospital from December 2018 to December 2019 were randomly selected as the research objects. 45 cases of diabetic patients were divided into the observation group and 45 cases of non-diabetic patients were divided into the control group. All the subjects were examined by color Doppler ultrasound, and the examination results of the two groups were observed and compared. result In the observation group, 34 cases (75.56%) had atherosclerosis, 35 cases (77.78%) had arterial plaque, 33 cases (73.33%) had lumen stenosis or occlusion; in the control group, 4 cases (8.89%) had atherosclerosis, 12 cases (26.67%) had arterial plaque, 8 cases (17.78%) had lumen stenosis or occlusion The incidence of atherosclerosis, atherosclerotic plaque and lumen stenosis or occlusion in the observation group was significantly higher than that in the control group; the blood flow rate and blood flow of the observation group were (35.12 ± 3.27) cm / s and (27.84 ± 9.18) ml / min; the blood flow rate and blood flow of the control group were (44.58 ± 3.93) cm / s and (45.67 ± 10.34) ml / min, respectively The flow rate was significantly lower than that of the control group (P < 0.05). Conclusion to sum up, color Doppler ultrasound in the early diagnosis of diabetic patients with lower extremity vascular disease has high clinical value and detection rate, which is worthy of promotion.
