- 2. Main groups of the hemodynamic disturbances violations of the blood volume (filling): hyperemia or congestion anemia
- 3. Reasons of circulatory disturbances Heart failure: of the myocardium (pump function failure) obstruction of blood outflow
- 4. Classification of blood circulation disorders According to the time of development: а) acute chronic According to
- 5. Types of systemic violations of blood circulation Shock Acute disorders of blood circulation at acute arrhythmia
- 6. Systemic disorders of blood circulation Reasons of development: Violations of heart rhythm and pump function. Violation
- 7. Shock It is a clinical state of cardiovascular collapse that develops under influence of extra-powerful stimuli
- 8. Classification of shock according to etiology and pathogenesis Hypo-volemic at: blood loss, trauma, peritonitis, cholera Cardiogenic
- 9. Stages of shock Compensation (non-progressive) – it is stage of centralization of blood circulation: а) blood
- 10. Shock morphology Main pathological processes at shock: DIC (disseminated intravascular coagulation) syndrome Hemorrhagic diathesis Liquid cadaver
- 11. Shock changes in organs а) Lungs – acute swollening of interstitial, lungs mass is increased in
- 12. It is a consequence of widespread activation of the coagulation system through endothelial injury and/or release
- 13. Reasons of death ⮚Acute respiratory insufficiency ⮚Acute kidney insufficiency ⮚Acute liver and renal insufficiency ⮚Perforation of
- 14. PATHOLOGY OF BLOOD FILLING Hyperemia Arterial General Ishemia General Vein Local Local Physiological Pathological neuroparalitical collateral
- 15. Hyperemia Hyperemia may be caused by: an increased supply of blood from the arterial system -
- 16. Generalized passive hyperemia (Congestion) Acute passive congestion is clinical consequence of acute left or right ventricular
- 17. Regional vein hyperemia It is a local vein plethora, observed at difficulty of outflow of vein
- 18. Arterial plethora Arterial plethora (active hyperemia) is promoted blood- involving of organ or tissue because of
- 19. Bleeding Bleeding (hemorrhage) — it is coming out of blood from the blood vessel or cavity
- 20. BLEEDING Internal Into serous cavities Hemopericardium Hemoperitoneum Hemarthrosis Hemothorax Into the tissue Hematoma Petechiae Purpura Ecchymosis
- 21. Reasons of bleeding: Break down of vessel wall Erosion of vessel wall Increased permeability of vessel
- 22. Thrombosis – It is rolling up of blood in the vessels or chambers of heart during
- 23. Virchow triad in thrombosis Endothelial integrity is the single most important factor, Local blood flow and/or
- 24. Thrombosis macroscopically It is necessary to distinguish a blood clot from the postmortem clot: A thrombus
- 25. Classification of thrombus, according to composition red blood clot – red coloring, quickly appears and consists
- 26. Classification according to the relation to vessel’s walls obstructive, that means, that a vessel is closed
- 27. Outcomes 1. organization - germination by the connecting tissue 2. petrification - deposition of calcium salts
- 28. Outcomes of thrombosis Arterial thrombi occlude the vessel and lead to ischemic necrosis of tissue (infarct).
