eng Abstract:
[eng][cze] At the present paper we report values of opening angles in human aortic bifurcations. A standard method of opening angle measurement was used. Three aortas were measured. Ten samples were excised from each aorta. Three rings were obtained from abdominal aorta close to the bifurcation, arteria iliaca communis dextra and sinistra and one form the bifurcation. The last one was composed of two rings, left and rignt, which were measured together. The residual strains were occurred in human aortic bifurcations and had different values in the left and the right branch of the bifurcated artery. The results of at the bifurcation can be influenced by fact that the branches of iliac arteries are still intergrown here. Two kinds of the opening angle investigation at the bifurcation were tested, a bifurcation septum fixed method and a circular sector fixed method. But both revealed differences in the opening angle values at the bifurcation.Cílem práce bylo popsat a změřit velikost zbytková deformace v bifurkaci lidské aorty. Bylo zjištěno, že i v těchto místech se zbytková deformace objevuje. Její velikost byla charakterizována pomocí úhlu rozevření kroužku tepenné stěny. Z každé aorty bylo vystřiženo deset kroužků. Porovnávány byly dva způsoby měření přímo v bifurkaci. Byly naměřeny různé hodnoty úhlu rozevření v jednotlivých větvích bifurkace při obou metodách uchycení vzorku. Hodnoty úhlu rozevření se pohybovaly v očekávaných mezích.
