Vasa vasorum of the coronary arteries in an animal heart model
Patzelt, Matěj ; Stingl, Josef (advisor) ; Laichman, Stanislav (referee) ; Slížová, Dáša (referee)
The vasa vasorum of the coronary arteries is a system of tiny vessels that nourish the wall of the coronary arteries. Recently, the vasa vasorum has been attributed importance in the pathogenesis of atherosclerosis, necrosis of the tunica media, or in excessive healing of the intima after stenting. The vasa vasorum system is described in detail on pathologically altered hearts, however, studies that would deal with a detailed description on a healthy human heart or on its animal model are minimal. The aim of the dissertation was to describe the structure and origin of the vasa vasorum of the coronary arteries on an animal model of the heart of a pig, to describe the history of the term vasa vasorum and possibly to describe secondary findings on the examined samples. A total of 36 healthy pig hearts were used in the study. Part of them was injected with India ink through the ostium of the coronary arteries and subsequently histologically processed, other hearts were directly fixed in toto in formalin and histologically processed, the remaining part of the hearts was injected through the ostium of the coronary arteries with mercox resin and then corrosive casts of the coronary arteries were created. These samples were evaluated using a scanning electron microscope. Histological processing of the...

Morphology of the Proximal Human Femur in Relation to Fractures of Trochanteric Massif
Báča, Václav ; Stingl, Josef (advisor) ; Koudela, Karel (referee) ; Chomiak, Jiří (referee) ; Laichman, Stanislav (referee)
AIM: Fractures of proximal end, especially fractures of trochanteric massif are very common particularly in old patients. The aim of the work was to try to find a morphological correlate of trochanteric fractures in the region of proximal end of the human femur. It means to find if a "locus minoris resistentiae" for trochanteric fractures origin exists. METHOD: The detailed overview of literature on femur as a bone, classification of trochanteric fractures and treatment of proximal end of the femur was accomplished (sources from medieval books to recent anatomical and clinical studies). Czech and Latin terminological aspect (Terminologia anatomica 1998) of the femur as well as their development were carefully studied. 40 femurs from embalmed bodies with muscles and ligaments were studied by detailed dissection. 99 X-ray pictures of pertrochanteric fractures were checked. 106 dry femurs from the vascular canal distribution point of view were evaluated and compared with previous group of X-rays. Statistic evaluation of normal distribution according to Kolmogorov-Smirnov's test and Liliefors's modification was made in 15 regions of trochanteric massif. 20 dry femurs according to Heřt, Fiala and Petrtýl's method were repeatedly ground to depict the central vascular canals and to describe the course of osteons...

The variability of the arteries of the shoulder, arm and forearm Clinical anatomy and study of the terminology in the relation to the efficacy of the catheterisation
Koňařík, Marek ; Kachlík, David (advisor) ; Stingl, Josef (referee) ; Laichman, Stanislav (referee)
The variability of the arteries of the shoulder, forearm and arm is the theme that may look as unimportant due to many of previous surveys made in the past years. Our work should point on a better understanding and simplification of the knowledges and the easy implication in the clinical medicine. Due to a massive development of microsurgery and radiological methods is the understanding of the vascular anatomy of the upper extremity crucial. During 10 years 423 upper limbs was dissected. We also evaluated 6709 angiography pictures of the upper limbs undergoing catheterisation from the archive of cardiological clinic of the university hospital in Pilsen and hospital in Liberec. Anatomical part of our study shows that the variability of the arteries of the upper limb ist approximately at 77%. The evaluation of the catheterisation shows, that in 99% of the patients undergoing the procedure, nevertheless the variability, via arteria radialis, was successful. Catheterisation via arteria radialis, also by the patients with vascular variation, is very safe procedure.
