观察超声引导穿刺抽吸和置管引流对细菌性肝脓肿的临床疗效.2017年1月—2019年10月,肝脓肿患者75例86个脓肿行超声介入治疗,对<4 cm的脓腔穿刺抽吸治疗,≥4 cm的脓腔置管引流.结果显示,<4 cm 53个脓肿,1次抽吸治愈率86.8(46/53),2次抽吸治愈率占9.4(5/53),3次抽吸治愈率占3.7(2/53).>5 cm 33个脓肿行置管引流治疗,30个一次性置管成功,2个实施二次置管,1个失败,转外科手术治疗,75例均在穿刺引流24 h后体温明显下降,3 d后白细胞计数及中性粒细胞计数恢复至正常,临床症状改善,随访6个月未见复发.结果表明,超声引导穿刺治疗细菌性肝脓肿为临床治疗细菌性肝脓肿的有效方法.
Objective:To evaluate the sternocleidomastoid muscle hardness in patients with tension-type headache (TTH) by acoustic radiation force impulse (ARFI), and to explore its clinical value in evaluating TTH.Methods:Thirty-five patients with TTH admitted to our hospital from March 2019 to March 2020 and 35 subjects accepted physical examination at the same time period were enrolled in this study. The thicknesses of sternocleidomastoid muscles were measured by two-dimensional ultrasound. On this basis, shear wave velocity (SWV) of sternocleidomastoid muscles was quantitatively evaluated by ARFI. The correlation between thicknesses of sternocleidomastoid muscles and headache was further analyzed.Results:The thickness of sternocleidomastoid muscles, SWV in transverse and longitudinal sections, visual analogue scale (VAS) scores in patients with TTH during headache and after massage were significantly higher than those in the heathy subjects ( P<0.05). Meanwhile, SWV in transverse and longitudinal sections, VAS scores decreased significantly in TTH after massage, which showed significant difference as compared with those during headache ( P<0.05). During headache, the thickness of sternocleidomastoid muscles was negatively correlated with VAS scores ( r=-0.397, P=0.002), SWV in longitudinal section of sternocleidomastoid muscles was positively correlated with VAS scores ( r=0.643, P=0.000). Conclusions:The thickness and hardness of sternocleidomastoid muscle are closely related with TTH. ARFI can quantitatively evaluate the thickness and hardness of sternocleidomastoid muscle.
目的 探讨高频超声在周围神经疾病诊断及治疗效果评价中的临床价值.方法 回顾性分析39例周围神经疾病患者的超声表现,并与术中及病理结果对照.结果 外周神经创伤性损伤15例,外周神经卡压16例,肢体外周神经源性肿瘤8例.超声对神经损伤、神经卡压及神经肿瘤的诊断符合率分别为73.3％、100％、62.5％.行神经吻合术患者中,16例神经束由吻合口近端向远端延伸,提示神经通路建立;5例吻合口明显膨大,吻合口内神经束对位较差;2例吻合处缩窄,提示神经通路未建立.结论 高频超声在诊断四肢周围神经疾病方面能精确判断损伤部位,较准确评估损伤的程度,为临床提供重要的诊断信息,有助于临床治疗方案的制定,同时能及时直观地评价神经损伤的治疗效果.
目的:探讨超声在膀胱占位性病变诊断及鉴别诊断中的价值。方法:回顾性分析45例膀胱占位性病变的声像图特征,并与病理结果对照分析。结果:45例膀胱占位性病变中恶性肿瘤42例,其中移行细胞癌37例,腺癌2例,鳞癌2例,低分化癌1例;良性病变3例,均为腺性膀胱炎。术前超声诊断对膀胱恶性肿瘤的诊断符合率为83%,对良性病变诊断的符合率为100%。结论:超声对膀胱占位性病变有较高的诊断价值,膀胱癌早期超声诊断容易误诊。
