The role of vegetovascular malfunction in primary dysmenorrhea pathogenesis

Abstract

Peculiarities of vegetovascular malfunction at functional dysmenorrhea has been investigated. 107 women with dysmenorrhea and 10 healthy women have been examined. Methods of pelvis minor organ rheography, rheoencephalography and cardiointervalography have been used. It has been revealed that at women with dysmenohhrea a disorganization  of  pelvis  minor  regional circulation developed during the first phase of menstrual cycle. It was evident in simultaneous decrease of cerebral vessel blood filling and increase of venous drainage, development of microcirculation disturbances. Simultaneously the enhancement  of  sympathetic effect and decrease of the effect degree of parasympathetic nervous system have been observed. On the contrary, at healthy women it is observed the enhancement of parasympathetic effect and the hemodynamic factors remain fixed.

The obtained results are evidence that at women with dysmenorrhea the marked vegetovascular disturbances connected with sympathetic tone prevalence and being evident mainly at cerebral hemodymanics level take place in the first  days  of  menstrual cycle. The nature of revealed disturbances is connected with the peculiarities of disease clinics.
