选择性动脉插管灌注化疗治疗中晚期胃癌２０例疗效观察洛阳市老城区医院耿振江，马星１９９０年１０月至１９９１年１２月，我们采用选择性动脉插管灌注抗癌药物治疗中晚期胃癌２０例，现报告如下。临床资料本组２０例中，男１６例，女４例。年龄５２～６８岁，平均６０岁...     

急症心脏瓣膜置换术(附15例报告)

本文报告急症心瓣膜置换术15例。按术前临床与病理的不同情况分为3组:①急性风湿性心脏炎;②感染性心内膜炎;③慢性心力衰竭急性发作。主动脉瓣置换术2例,二尖瓣置换术13例。市后早期死亡6例,长期生存9例。生存一年以上7例均恢复工作。本文对急症瓣膜置换术的指征,手术的特殊处理与术后处理的特点进行了讨论。     

高压氧治疗厌氧性感染(梭状芽胞杆菌属)的实验性观察(附临床病例报告)

一、实验菌液的配制:本组实验系采用产气荚膜杆菌06号菌株接种子肉渣汤内,经37℃孵育18～20小时后,用普通肉汤稀释成不同浓度,分别注射于豚鼠(体重300～500克)肌肉内务0.5毫升。每种菌液浓度注射2只动     

心肌内膜纤维化:临床表现与外科治疗的作用

心肌内膜纤维化在赤道非洲常见。到过赤道非洲或居住过的人也可发生。特点为病变侵犯心室腔,特别在心尖与瓣膜下部位。临床上很象风湿性心脏病。心脏 X 线检查为重要诊断方法之一。心肌活组织检查可确诊。治疗至今仍为内科处理。据报道,自出现症状平均生存时间为2年。外科手术纠正异常血流动力学的效果很好,虽然其最终预后不会改变,但可使患者获得较好的生活。例1:28岁男性,入院前6年开始活动后心慌气     

体外循环时应用甲基去氢氢化可的松:427例总结

体外循环的目的在于维持足够的组织灌注,达到此目的有赖于在足够的灌注压下维持充分的流量。流量与灌注压的平衡取决于周围血管张力。当体外循环进行时,血循环内肾上腺素和去甲肾上腺素增加,引起血管收缩,因此预期降低血管收缩反应将可获得     

用Hall-Kaster:瓣膜置换主动脉瓣的初步临床经验

Hall-Kaster瓣膜(附图)的主要设计目的是开放时对血流的阻碍减少到最小程度,并增大小孔的开口,开放时瓣碟将瓣口分为近似的两等份。瓣碟的厚度小于2毫米,中央有一孔。石墨基体内有钽,使瓣碟不透X光,表面涂盖各向同性碳使瓣碟得到最大耐磨性、光洁度和电阴性。瓣架由整块钛雕挖     

带环涤纶人造血管移植胸主动脉动物实验观察

应用合成纤维制作的人造血管作胸主动脉移植,应用已久。但对主动脉瘤两端血管病变范围广泛,管壁脆弱者,采用人造血管缝合的方法,可因缝线割裂,引起致命性大出血;而且缝合法多需采用左心辅助循环装置,增加了手术的复杂性与危险性。为此,作者设计了一种带环涤纶人造血管,采用套合结扎法,作胸主动脉移植术,实验证明效果良好,报告如下。     

EXPERIENCE WITH 124 CONSECUTIVE E.LECTIVE MITRAL VALVE REPLACEMENT WITH SHANGHAI-MADE TILTING DISC PR.OSTHESIS

124 consecutive elective mitral valve replace- ments were performed with Shanghai-made tilting disc prosthesis without early mortality. All patients had chronic theumatic valvular diseases with mitral valve stenosis and insufficiency. Functional classi- fication revealed that 96.78'70 0f the patients belong- ed to Class III and IV. 66To had moderate and severe pulmonary hypertension, of these 14.51To (18 patients) had early postoperative complications with out sequalae. Follow-up for 4-36 months (mean: 18.39+8.03 months) showed 6 late deaths (3.15'70 0ne year). The causes of two deaths were bleeding due to overdose of anticoagulant and septicemia respec- tively, whereas the rest four died of unknown cause. 118 patients were long-term survivors, 113 0f them have been living more than 6 months. The cardiac function of most patients was improved from Class III or IV to Class I or II postoperatively. 74 (89.15+) of 83 patients have been living more than one year and resumed their work. We consider that there are many reasons for the achievement of ex- cellent results, and seven of them are described in detail.     

深低温体外循环下二尖瓣狭窄合并关闭不全的直视手术治疗(附15例报告)

闭式手术矫正二尖瓣狭窄,虽应用二尖瓣扩张钳扩张较手指分离为佳,但仍由于带有一定的盲目性,难以适当地扩张至理想程度,尤其对病变较为严重如瓣叶钙化、瓣下粘连及收缩等,不但难以获得良好的疗效,而且易损伤瓣膜或腱索并发关闭不全,造成术后病情恶化。此
