心脏导管插入术为一优良新技术,操作熟练时甚少引起严重合并症。1968年的估计发生率为3.4%,1974年统计许多研究所的总发生率为1.5%,其中少于1/4为神经系统合并症。关于神经系统合并症的确切发病机理目前尚不十分清楚,根据对许多病例的观察似与对比荆的反应、心肌的应激性、心肌梗塞及栓塞有关。 Cardiac catheterization is an excellent new technique that rarely causes serious comorbidities when manipulated. The estimated incidence in 1968 was 3.4%. In 1974, the total incidence of many research institutes was 1.5%, of which less than 1/4 was neurologic complications. The exact pathogenesis of neurological comorbidities is not well understood at present, and is based on the observation of many cases that it is related to the response to stress, myocardial stress, myocardial infarction, and embolism.
