Hemodynamic disorder

• Hyperemia

  • Active process in which arteriolar dilation leads to increased blood flow
• Affected tissues turn red - erythema
• Acute Appendicitis

  ETIOLOGY: overt luminal obstruction; 50-80% due to fecalith
• Acute Appendicitis —PATHOGENESIS: initiated by progressive increases in intraluminal pressure – compromise blood flow – overt luminal obstruction
• Chronic Passive Congestion (CPC) of the Lungs

  Etiology: Left-sided heart failure
• Thrombosis

  • Pathologic counterpart of hemostasis
• Blood clot (thrombus) formation in an intact blood vessel— thrombosis
• Most common is detached thrombus – thromboembolus
• Embolus — Detached intravascular solid, liquid or gaseous mass, carried by blood to a site distant from its point of origin
