[The so-called recanalisation of cotyledonary vessels with endangitis obliterans of placenta vessels (author's transl)].

With a graphic reconstruction on serial sections, performed with placentas which altogether showed so-called recanalisation, it is possible to work out the fact, that the recanalisation is an effect of the paravascular capillary network and with it to clarify the problem of the so-called recanalisation. It is proved, that the paravascular capillaries undertake compensatory hemodynamic functions and this undertaking of function prevents a complete occlusion of the cotyledonary vessels, so that you have to speak of restlumen and restflow but not of recanalisation. The endangitis obliterans of cotyledonary vessels is again unequivocally pointed out by this phenomenon as a intravital process.
