Considering our own data and after reviewing the literature the following conclusions can be drawn: 1. In 0.41% of all births the incidence of a chorioangioma is to be expected. 2. Small chorioangiomas are much more frequent than large ones. In most cases, they occur solitary, only sometimes multiple. 3. Most of the chorioangiomas are located centrally in placental tissue or at the fetal side in relation to the chorion. 4. A classification of five histological types can be made: Type I: Endotheliomatous chorioangioma; Type II: Capillary chorioangioma; Type III: Cavernous chorioangioma; Type IV: Fibrosing chorioangioma; Type V: Fibroma. 5. There is no significant relationship to the mother's age. The incidence is higher in primipari. The rates of gestones as well as the rates of prematurity and still birth increased with these tumors. 6. Hydramnion as well as fetal complications are entailed with large or multiple tumors.
综合我们自己的数据并查阅文献后，可以得出以下结论：1. 在所有分娩中，预计绒毛膜血管瘤的发生率为0.41%。2. 小的绒毛膜血管瘤比大的更为常见。在大多数情况下，它们是单发的，仅偶尔多发。3. 大多数绒毛膜血管瘤位于胎盘组织中央或相对于绒毛膜的胎儿侧。4. 可分为五种组织学类型：I型：内皮瘤样绒毛膜血管瘤；II型：毛细血管性绒毛膜血管瘤；III型：海绵状绒毛膜血管瘤；IV型：纤维性绒毛膜血管瘤；V型：纤维瘤。5. 与母亲年龄无显著关系。初产妇的发生率较高。这些肿瘤会使孕酮水平以及早产和死产率升高。6. 巨大或多发肿瘤会导致羊水过多以及胎儿并发症。
