    Bilateral asymmetry of the pericardial neurovascular bundles
    (2025) Khmara, T.V.; Skypnyk, V.M.; Osypenko, Ye.Ye.
    The study investigates the morphological features and the existence of bilateral asymmetry in the pericardial neurovascular bundles (NVBs). It is substantiated that NVBs, which include nerves and blood vessels supplying the pericardium, play a key role in the autonomic regulation of heart function. An analysis of the bundles' structure on the right and left sides of the pericardium is conducted. It is established that there is pronounced asymmetry in the number, diameter, and topography of the constituent elements, with the right side often exhibiting greater structural complexity. The content highlights the clinical significance of this asymmetry, particularly for cardiac and thoracic surgeons. The conclusion is made that detailed anatomical knowledge of NVB asymmetry is critical to minimize the risk of damage to the autonomic innervation and blood supply during surgical procedures involving the pericardium.

    Ultrasound examination of the bones of the lower leg in human fetuses
    (ПВНЗ «Харківський міжнародний медичний університет», 2024) Khmara, T.V.; Pankiv, T.V.; Kovalchuk, P.Ye.
    The study presents the results of intravital ultrasound examination of the tibia and fibula in 32 human fetuses. Morphometric analysis revealed uniform growth of the right and left tibia and fibula during the fetal period. From the 4th to the 10th month of pregnancy, the tibia length increased 2.61–2.64 times, and the fibula length increased 2.66 times. The findings provide normative age-related values for ossification centers of the tibia and fibula, which are important for assessing gestational age, early diagnosis of chromosomal abnormalities, and skeletal dysplasias.
