[Chorangiomas (hemangiomas of the placenta). I. Pathological anatomy and pregnancy complications].
Clinical and pathologic-anatomic criteria were compared in 233 cases of chorangiomas from literature (7 own observations among them). Concerning parity and age of the patients there were no peculiarities. Hemorrhages before, during and after birth could be observed more frequently. Operations like caesarean section, forceps and manual removal of placenta have not been carried out more than in a normal frequency. In chorangiomas there were more gemini and more female fetuses. An explanation of these phenomena cannot be given. The same can be applied to the accumulation of gestoses and hydramnios, especially in large chorangiomas. A histologic examination of the placentas is proposed in complicated pregnancies, especially in gestoses and hydramnios. Only in this way it may be possible to detect microscopically small chorangiomas connections with the complications of pregnancy listed above.
