单心室解剖形态观察(附17例尸检报告)

Morphological study of single ventricle ( Report of 17 autopsied cases )

单心室是一种极复杂的先天性心血管畸形。心室区多数伴有一个残留室腔。患者能否长期存活和具有手术矫治的机会,要视心内畸形、体静脉、肺静脉回流和大动脉发育状况的复杂程度而定。本文通过17例尸检心脏的解剖形态研究,按房室连接方式将单心室划分为两大类:即经典类和左房室或右房室连接缺如类。根据主室腔的解剖特征,每类又分为左室和右室两型.

Single ventricle is a very complicated cardiovascularmalfor- mation.In the majority of cases a rudimentary chamber is accompanied within the ventricular mass whether the patient being able to have a long life span or receive surgical intervention is depending on the compl- exity of the intracardic lesions,the systemic and pulmonary venous circul- ation and the development of the major arteries.A series of 17 cases were studied morphologically and segmentally.There were two groups of single ventricle which had been classified by the mode of AV connexion—the classic and the absent of right or left AV connection groups.According to the morphological characters of primary chamber,each group could be also divided into left and right ventricular type.
