    • Research progress on echocardiography evaluation for left atrial remodeling and reverse remodeling

      With the deepening of research on cardiovascular diseases, left atrial remodeling (LAR) and left atrial reverse remodeling (LARR) have become important research hotspots, closely related to various adverse cardiovascular pathological changes. As a non-invasive and convenient diagnostic tool, echocardiography plays a crucial role in the diagnosis, treatment monitoring, and prognosis evaluation of LAR and LARR. This article reviews the research progress of echocardiography in evaluating LAR and LARR, involving transthoracic echocardiography, tissue Doppler imaging, two-dimensional speckle tracking echocardiography, and three-dimensional speckle tracking echocardiography, and explores their advantages and limitations in clinical practice.

    • Analysis of the Treatment for Acute Stanford Type A Aortic Dissection in Primary Hospital

      目的探討急性Stanford A型主動脈夾層的臨床特點、基層醫院救治策略及圍術期常見并發癥的處理措施。 方法回顧性分析遂寧市中心醫院2010年2月至2013年9月16例采用三分支主動脈支撐型覆膜支架重建弓部手術治療的Stanford A型主動脈夾層患者的臨床資料,其中男12例、女4例,馬凡綜合征1例,原發性高血壓病15例。分析其臨床特點、影像學表現及治療效果。 結果16例患者手術均成功。本組體外循環時間(202.2±50.4)min,升主動脈阻斷時間(94.6±16.9)min,深低溫停循環時間(11.5±7.4)min,選擇性腦灌注時間(40.6±6.8)min,術后胸腔及心包積液引流量(700.6±368.6)ml,重癥監護室停留時間3~26 d。住院期間死亡1例,于術后28 d突發遠端夾層破裂死亡。術后發生慢性心臟壓塞導致胸骨哆開1例,10例出現一過性精神障礙,5例并發急性腎功能不全,4例出現急性呼吸功能不全,3例出現急性肝功能不全。術后隨訪15例,門診及電話隨訪6~49個月;2例于術后1年隨訪中因其他慢性疾病死亡;其余13例均存活。 結論基層醫院采用三分支主動脈支撐型覆膜支架重建弓部手術治療急性Stanford A型主動脈夾層,簡化了手術方式,針對圍術期并發癥采取有效的治療措施可顯著提高患者生存率。
