Echocardiographic assessment of interior vena cava (IVC) is a part of estimation of right atrial pressure. In young women values exceeding norm are observed. The aim of our study was an echocardiographic assessment of IVC dimension depending on the phase of menstrual cycle among young, healthy women.
Materials and methods
Female students of Medical University of Gdansk were enrolled to the study. Each patient underwent echocardiographic examination of IVC diameter (d-IVC) and respiratory decrease in dimension in two time points, depending on the phase of menstrual cycle: in the first days of menstruation (Phase M), in the second part of menstrual cycle (Phase L).
Results
31 patients completed the study. There was a significant difference between the d-IVC in Phase M and Phase L (1.98±0.25cm vs 1.86±0.3cm; p <0.05). We did not observe correlation in terms of the inspiratory collapsibility. In the Phase M 77% patients achieved at least 50% decrease in dimension during inspiration comparing to 87% in Phase L (p=0.89). 35% patients had d-IVC exceeding reference values.
Conclusion
In population of young women diameter of IVC exceeding reference values can be observed. IVC dimension dependents on the menstrual cycle.
