急性腦梗死患者左心室功能的改變

【摘要】 腦梗死是一種致死、致殘的常見病。急性腦梗死可以引起患者左心室收縮及舒張功能改變,臨床上可出現心律失常,嚴重者可出現室顫、心源性猝死。急性腦梗死患者心電圖異常發生率達72%,主要表現T波低平、ST段下移、病理性Q波、心律失常。通過心臟彩超檢查,研究急性腦梗死患者心臟結構與功能改變發現,急性腦梗死與左心室射血分數、心輸出量、E/AB比值具有相關性,提示急性腦梗死可引起左室收縮及舒張功能減低。急性腦梗死后發生心電圖異常改變,與腦梗死部位有關;心功能異常可能影響腦梗死患者預后。有關左心室功能改變與腦梗死大小、部位,以及與頸動脈硬化及斑塊的相關性研究還需要進一步闡明。

高頻彩超定性診斷乳腺占位病變的應用價值

【摘要】目的 評價高頻彩超對乳腺占位病變定性診斷的應用價值。方法 總結2004年1月-2009年9月收治的200例經手術病理證實的乳腺占位病變的高頻彩超影像特征,并與病理學結果相比較。結果 高頻彩超初步定性診斷與病理診斷的符合率為94%(188/200),誤診率為6.0%(12/200)。結論 高頻彩超檢查有助于定性診斷乳腺占位病變。

彩超提示下穿刺沖洗治療兒童頜面間隙感染

摘要:目的:對兒童頜面間隙感染形成膿腫早期病例采用彩超提示下局部穿刺吸膿,藥物沖洗膿腔,保守治療,避免手術切開排膿遺留瘢痕。方法: 兒童頜面間隙感染102例, 在常規抗感染治療的基礎上采用彩超提示下經皮穿刺奧硝唑與慶大霉素沖洗治療。結果:102例中92例經穿刺治療后痊愈,10例無效作膿腫切開引流,有效率為90.20%。結論: 彩超提示下穿刺沖洗治療兒童頜面間隙感染具有創傷小、可操作性強、能有效縮短病程、愈后不留瘢痕等特點,是治療頜面間隙感染膿腫形成早期的有效方法。

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

目的　探討乳房腫物體表定位膜對乳腺彩超結果的影響。方法　回顧性分析2010年12月至2011年1月期間，筆者所在醫院乳腺門診檢查觸診陰性的180例患者共236個乳房腫物貼膜前后的彩超檢查結果，分析其血運、邊界、鈣化及分級情況的變化。結果　貼膜后，236個腫物中有2個血運情況有變化，7個邊界有變化，5個鈣化情況有變化，5個分級有變化，但貼膜前后乳房腫物的血運（P=0.500）、邊界（P=0.136）、鈣化（P=0.082）及分級（P=0.172）變化情況比較差異均無統計學意義。結論　乳房腫物體表定位膜不影響乳房腫物的彩超檢查結果。

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.
