室间隔缺损的解剖分型及其临床意义

Anatomic classification of ventricle septal defects and its clinical significance

目的：探讨室间隔缺损解剖分型的临床意义。方法：按照Ｓｏｔｏ的分类方法略加改进，将３５０例室间隔缺损分为４个解剖类型，并与其临床表现相对照。结果：３５０例室间隔缺损中，７６％（２６６例）为膜周型，缺损均与室间隔膜部关连；１９．４％（６８例）为干下型，位于肺动脉与主动脉相遇的左右瓣环下；０．９％（３例）为肌型，可见于肌部间隔的任何一处；３．７％（１３例）为混合型，包括单个大型缺损涉及室间隔多个部位或同时出现两种以上的单个室间隔缺损。描述了各型室间隔缺损的主要临床征象。外科医生可据此选择合适的手术切口及手术方法。

Objective:To demonstrate the clinical significance of the anatomical classification of ventricular septal defect (VSD)Methods:We modified the Soto′s classification,and divided 350 cases of VSD into four anatomical typesTheir clinical signs were compared with their anatomical typesResults:The four types are:I:76% of them (266 cases) are perimembranous type,the defects are variously related to the ventricular portion of the membranous septumⅡ:194% of them (68 cases) are subpulmonary type,the defects are lying immediately beneath the pulmonary and aortic valvesⅢ:09% of them (3 cases) were muscular types,the defects are anywhere in the muscular septumⅣ:37% of them (13 cases) were mixed typesThe main clinical signs of each type of VSD were described in detailConclusions:The anatomical classification of VSD is valuable for their clinical diagnosis and treatment
