Aneurysm-like kialations of the membranous septum are described with increasing frequency in association to a ventricular septal defect (VSD). Their etiology may be congenital, though with different pathogenesis and acquired. An anatomical distinction between true aneurysm of the membranous septum and pseudoaneurysm is proposed. The acquired forms may be joined to a decrease of left to right shunt and are regarded as the mechanism of closure of a VSD. Nine cases of aneurysm-like dilation of the membranous septum are presented: an interpretation of their etiology and pathogenesis is discussed, on the basis of the history and clinical and instrumental data.
膜周部间隔瘤样扩张与室间隔缺损（VSD）相关的报道日益增多。其病因可能是先天性的，尽管发病机制不同，也可能是后天获得性的。本文提出了膜周部真正动脉瘤与假性动脉瘤的解剖学区分。后天性形式可能与左向右分流减少有关，并被视为室间隔缺损闭合的机制。本文报告了9例膜周部间隔瘤样扩张病例：根据病史、临床和检查资料，对其病因和发病机制进行了讨论。
