AN ANALYSIS OF HEMODYNAMICS OF THE ANTERIOR DESCENDING BRANCH OF THE ARTERIA CORONARIA SINISTRA

This paper analyses the anterior descending branch of the arteria coronaria sinistra from the view of hemodynamics.The results show that the branching of the anterior descending branch with an angle of 90?at the opening and the formation of the mural arteria coronaria are the hemodynamic characteristics.The shearing stress of the turbulent flow, the additional pressure, the formation of the blood vertex, and the impulsive pressure, caused by these characteristics, are hemodynamic reasons that leads to the occurence of atherosclerosis in anterior descending branch.

单纯阻断肾静脉左肾静脉下移治疗胡桃夹综合征的临床护理

目的探讨单纯阻断肾静脉左肾静脉下移治疗胡桃夹综合征围手术期的护理。方法回顾性分析总结6例单纯阻断肾静脉左肾静脉下移术后患者围手术期护理过程及经验。结果对6例单纯阻断肾静脉左肾静脉下移术的护理要点包括心理护理、尿道准备、术后特殊体位的护理;血尿的观察及腹膜后出血、血肿等并发症的严密观察。结论良好的具有针对性的全程性护理对单纯阻断肾静脉左肾静脉下移术治疗胡桃夹综合征的成功至关重要。
