目的 改进肺动脉栓塞诊断治疗技术，降低死亡率，提高治愈率。方法 总结了1987年9月至1998年3月11例肺动脉栓塞病例。重点分析了常见病因、临床表现及核素肺扫描等检查方法，比较了治疗方法及疗效。结果 7例呼吸困难等症状消失，6例肝脏肿大等体征明显好转，6例血气指标恢复正常，肺核素扫描正常。治愈率63.3%(7/11)，死亡率36.4%(4/11)。结论 放射性核素肺扫描有很高的诊断价值，应作为必检项目，及时诊断和有效治疗，是提高存活率、增加治愈率的重要因素。“,”Objective To improve the technique for diagnosis and treatingpulmonary embolism,reduce the mortality rate and raise the cure rate.Methods Eleven cases of pulmonary embolism from September 1987 to March 1998 were summarized.The common pathogeny,clinical manifestation,nuclein lung scanning and some examination methods were emphatically analyzed.Further more,kinds of treatments and effects were compared.Results Some symptoms,like dyspnea in 7 cases disappeared.Some signs,like hepatauxe in 6 cases were obviously improved.The index of blood gas and nuclein lung scanning in 6 cases return to normal.Over all clinic cure was 63.6%(7/11) and hospital mortality was 36.4%(4/11).Conclusion Radioactive nuclein lung perfusion scanning plays an important role in diagnosing pulmonary embolism and valid treatment are the most important factors for raising the survival rate and increasing the cure rate.
