彩超提示下穿刺冲洗治疗儿童颌面间隙感染

摘要:目的:对儿童颌面间隙感染形成脓肿早期病例采用彩超提示下局部穿刺吸脓,药物冲洗脓腔,保守治疗,避免手术切开排脓遗留瘢痕。方法: 儿童颌面间隙感染102例, 在常规抗感染治疗的基础上采用彩超提示下经皮穿刺奥硝唑与庆大霉素冲洗治疗。结果:102例中92例经穿刺治疗后痊愈,10例无效作脓肿切开引流,有效率为90.20%。结论: 彩超提示下穿刺冲洗治疗儿童颌面间隙感染具有创伤小、可操作性强、能有效缩短病程、愈后不留瘢痕等特点,是治疗颌面间隙感染脓肿形成早期的有效方法。

高频彩超定性诊断乳腺占位病变的应用价值

【摘要】目的 评价高频彩超对乳腺占位病变定性诊断的应用价值。方法 总结2004年1月-2009年9月收治的200例经手术病理证实的乳腺占位病变的高频彩超影像特征,并与病理学结果相比较。结果 高频彩超初步定性诊断与病理诊断的符合率为94%(188/200),误诊率为6.0%(12/200)。结论 高频彩超检查有助于定性诊断乳腺占位病变。

急性脑梗死患者左心室功能的改变

【摘要】 脑梗死是一种致死、致残的常见病。急性脑梗死可以引起患者左心室收缩及舒张功能改变,临床上可出现心律失常,严重者可出现室颤、心源性猝死。急性脑梗死患者心电图异常发生率达72%,主要表现T波低平、ST段下移、病理性Q波、心律失常。通过心脏彩超检查,研究急性脑梗死患者心脏结构与功能改变发现,急性脑梗死与左心室射血分数、心输出量、E/AB比值具有相关性,提示急性脑梗死可引起左室收缩及舒张功能减低。急性脑梗死后发生心电图异常改变,与脑梗死部位有关;心功能异常可能影响脑梗死患者预后。有关左心室功能改变与脑梗死大小、部位,以及与颈动脉硬化及斑块的相关性研究还需要进一步阐明。

Effects of Mammary Tumor Surface Positioning Membrane on Results of Mammary Gland Ultrasound Examination

目的　探讨乳房肿物体表定位膜对乳腺彩超结果的影响。方法　回顾性分析2010年12月至2011年1月期间，笔者所在医院乳腺门诊检查触诊阴性的180例患者共236个乳房肿物贴膜前后的彩超检查结果，分析其血运、边界、钙化及分级情况的变化。结果　贴膜后，236个肿物中有2个血运情况有变化，7个边界有变化，5个钙化情况有变化，5个分级有变化，但贴膜前后乳房肿物的血运（P=0.500）、边界（P=0.136）、钙化（P=0.082）及分级（P=0.172）变化情况比较差异均无统计学意义。结论　乳房肿物体表定位膜不影响乳房肿物的彩超检查结果。

Effect of Preoperative Carotid Duplex Ultrasound to Prevent Nonrecurrent Laryngeal Nerve Injury During Thyroid Surgery

ObjectiveTo investigate the clinical value of cervical vascular color Doppler ultrasound for dignosis of nonrecurrent laryngeal nerve before thyroid surgery. MethodsThere were 1931 cases of thyroid patients treated between January 2010 to Jule 2014, group these patients according to the results of preoperative chest radiograph examination, the chest radiograph shows abnormal vessels image were group A (45 cases), no abnormalities were group B (1886 cases). Before operaton, made patients of group A to have routine carotid duplex ultrasound to identify whether the right subclavian artery abnormalities. All patients were exposed to conventional methods of recurrent laryngeal nerve during surgery. ResultsThe 45 patients of group A, chest angiography showed 17 cases with right subclavian artery abnormalities, they were confirmed that all the 17 patients were nonrecurrent laryngeal nerve by surgery, no damage cases. The other 28 cases showed a normal right subclavian artery and no cases of nonrecurrent laryngeal nerve. The 1886 patients in group B, surgical exploration found four cases with nonrecurrent laryngeal nerve, injury in 1 case. The 21 patients whose nonrecurrent laryngeal nerve were on the right side, there were no left side with nonrecurrent laryngeal nerve and no co-exist cases of nonrecurrent and recurrent laryngeal nerve. The average exposure time of nonrecurrent laryngeal nerve in patients of group A (17 cases) was significantly shorter than that group B[(4.28±1.08) min vs. (15.50±2.08) min, t=-15.978, P=0.000]. ConclusionsThe cervical vascular color Doppler ultrasound examination before thyroid surgery can be adjuvant used, if there is the right subclavian artery abnormalities, it showes that there is the right side nonrecurrent laryngeal nerve. So as to effectively prevent the damage of nonrecurrent laryngeal nerve during thyroid surgery.
