主动脉内球囊反搏术后患者的观察及护理

主动脉内球囊反搏术（IABP）是对左心室功能衰竭和缺血性心血管疾病的机械性循环支持疗法之一。本院近年收治6例行IABP的患者，现将术后护理体会介绍如下。     

升主动脉成形术中期效果分析

Objective Reduction ascending aortoplasty is an alternative procdure to the replacement of the ascending aorts in case of ascending aorta dilation. However,its applicabikity is still under debate.This retrospective study was designed to evaluuate the midterm follow-up of unsupported ascending reduction aortoplasty for of the ascending aorta in petients with aortic valve dis- ease.Methods From October ,1996 to April,2007, a total of 54 patients with aortic valve disease and dilatation of the ascending aorta underwent unsupported reduction aortoplasty in combination with aortic valve replacement at our institution The diameter of the ascending aorta was measyred before and early after sugery and then later between 13 and 96 menths [mean (23 ±16)months] posto- perativeiy using echocardiography.Results Two patients were dead with thean overall perioperative mortality rate was of 3.7%. The reduction aortoplasty decreased the diameter of the aorta from (45.77±6.02) mm p～eope～afive]y to (34.67 ～4.81) mm early after surgery (P<0.01). During follow-up, the diameter d aorta increased from (34.67±4.81) mm early after surgery to (37.65± 6.35) mm after a mean follow-up of (23±16) months (P<0.01), including the diameters are greater than > 45 mm within 5 pa- tients. Aortic stenosis and an early postoperative diameter greater than 40 mm m'e independent risk factors for redilatation. Conchusion Because of the unsatisfied midterm follow-up redilation of unsupported reduction aortoplasty for dilation of the ascending aorta with aortic valve disease, this group of patients needs continued intimate fallow-up or even reoperation. The patients of stenosis is the surtable indication for RAA, and it is necessary to reduce the diameter of aorta to be lees than 40 mm to prevent redilation.     

动脉粥样硬化的实验研究 Ⅳ动脉粥样硬化家兔主动脉平滑肌细胞…

探讨动脉粥样硬化家兔主动脉平滑肌细胞增殖与血小板胞浆游离钙水平、血小板聚集性变化的关系。发现高脂血症家兔主动脉平滑肌细胞较正常平滑肌细胞增殖明显增强。经高脂血清孵育的平滑肌细胞增殖增强。此外高血脂动物的血小板胞浆游离钙水平与聚集性也增强，提示高脂血清及血小板释放ＰＤＧＦ增多可能是刺激平滑肌细胞增殖的原因。用具有降脂作用的中药有效成分８５０１处理的家兔主动脉平滑肌细胞和用８５０１处理的家兔血清孵育后     

主动脉夹层瘤10例护理体会

<正> 主动脉壁中层囊性坏死时,若受到大的血流动力的冲击,可发生夹层动脉瘤。密切观察及护理对疾病的预后有重要意义。现结合10例分析,将我们的护理体会报告如下。 1 临床资料 我院从1986年6月到1996年6月收治10例夹层动脉瘤,均为男性,年龄42—81岁。均有高血压病。2例有高心病,3例有陈旧性心梗,1例急性肾衰,4例主动脉瓣关闭不全并急性左心衰。1例自动出院、2例死亡,治愈好转率70％。     

主动脉夹层动脉瘤误诊分析

目的分析主动脉夹层动脉瘤的误诊情况,以期提高对此病的认识。方法回顾性地对新乡市中心医院1991-2002年间收治的8例主动脉夹层动脉瘤患者的临床表现、初期诊断情况进行分析。结果初期误诊5例,初期误诊率为62.5％。结论主动脉夹层动脉瘤病情复杂,误诊率高,预后差,临床医生应提高对该病的认识,以期早诊断、早治疗。

胸主动脉假性动脉瘤致食管狭窄1例

1临床资料患者,男,30岁,因车祸伤及胸部致右侧多发性肋骨骨折、右侧气胸、左侧血胸入院。给予双侧胸腔置管引流术等处理,病情稳定,能下床活动。伤后12天突发截瘫,经MRI证实为胸主动脉左锁骨下动脉分支假性动脉瘤,长约4cm,管腔基本被极化血块堵塞,致使瘤以下血流缺失,导致截瘫,无尿;截瘫后30小时在全麻体外循环下行动脉瘤切除人造血管置换术,术后病情稳定,截瘫未恢复,出现进行性吞咽困难,术后1个月余完全不能进水,钡餐透视显示食管中下段交界以下重度狭窄,行胸部CT检查排除食管机械外压情况,发现下段食管贲门上不狭窄,狭窄段仅位于中下段交…
