Methods for balloon dilatation of stenosis of the aortic orifice through an arterial and venous approaches are suggested. The method was approved in treatment of 51 patients whose ages ranged from 4 to 63 years. Retrograde advancement of the balloon to the constricted part is most rational. In antegrade movement of the balloon there is a hazard of inflicting injury to the structures of the mitral valve (4 cases). Both methods produce a similar therapeutic effect: the area of the orifice increased 4.3 times, the systolic pressure gradient reduced by 3.3 times. II degree aortic insufficiency developed in 2 patients and I degree insufficiency in 3 patients. The method may be an alternative in the treatment of valvar and membranous subvalvular aortic stenosis.
提出了经动脉和静脉途径对主动脉口狭窄进行球囊扩张的方法。该方法已被批准用于治疗51例年龄在4岁至63岁之间的患者。将球囊逆行推进至狭窄部位最为合理。在球囊顺行移动时，存在损伤二尖瓣结构的风险（4例）。两种方法产生相似的治疗效果：瓣口面积增加4.3倍，收缩期压力梯度降低3.3倍。2例患者出现Ⅱ度主动脉瓣关闭不全，3例患者出现Ⅰ度关闭不全。该方法可能是治疗瓣膜性和膜性瓣下主动脉狭窄的一种替代方法。
