Study Notes
Lymphatic Obstruction Edema
- Lymphoedema is a type of edema where edema fluid is a lymph, except in inflammatory edema (exudate) and lymphatic edema (lymph).
Hemorrhage
- Hemorrhage is the escape of blood outside the cardiovascular system.
- Causes of hemorrhage:
- Local: trauma, erosion of blood vessel by tumor
- General: bleeding tendencies, anticoagulant therapy
- Types of hemorrhage:
- Interstitial hemorrhage: accumulation of blood within interstitium
- Internal hemorrhage: blood escape inside body cavities
- External hemorrhage: escape of blood through body orifices
Interstitial Hemorrhage
- Definition: accumulation of blood within interstitium
- Types:
- Petechiae: 1-2 mm in diameter, found in skin, mucous membranes, or serosal surfaces
- Purpura: larger hematomas, more than 3 mm in diameter
- Ecchymosis: larger subcutaneous hematomas, 1-2 cm in diameter
Internal Hemorrhage
- Definition: blood escape inside body cavities
- Types:
- Hemothorax: hemorrhage into the pleura
- Hemopericardium: hemorrhage into the pericardium
- Hemoperitonium: hemorrhage into the peritoneum
- Hemoartherosis: hemorrhage into a joint cavity
- Hematocele: hemorrhage into the tunica vaginalis
External Hemorrhage
- Definition: escape of blood through body orifices
- Examples:
- Epistaxis: bleeding from the nose
- Hemoptysis: coughing of blood from lung or bronchi
- Hematemesis: vomiting of blood from esophagus, stomach, duodenum
- Melena: digested blood passing with stools
- Blood per Rectum: undigested blood passing with stools
- Hematuria: blood passing with urine
- Menorrhagia: prolonged excessive menstrual bleeding
- Metrorrhagia: irregular uterine bleeding not related to menstruation
Gangrene
- Definition: necrosis with putrefaction
- Types:
- Dry gangrene: occurs especially in toes, caused by gradual arterial obstruction, characterized by minimal tissue fluid, black, dry, and shrink
- Wet gangrene: occurs in internal organs and feet of elderly, especially intestine, caused by sudden arterial and venous obstruction, characterized by excess tissue fluids
Edema
- Definition: abnormal accumulation of fluid in the interstitial tissue or body cavities
- Sites:
- Subcutaneous tissue
- Serous sacs: pleura, peritonium, and pericardium
- Pathogenesis:
- Increased intravascular hydrostatic pressure
- Increased vascular permeability
- Decreased plasma oncotic pressure
- Lymphatic obstruction
- Classification:
- According to site: localized, generalized
- According to consistency: pitting, non-pitting
- According to fluid: transudate, exudate, lymph
Ischemia and Infarction
- Ischemia: decreased blood supply to tissue due to occlusion of its artery
- Types:
- Acute: caused by embolus, thrombus
- Chronic: caused by atherosclerosis, pressure by tumor
- Infarction: an area of necrosis due to acute ischemia in an organ with endarteries
- Gangrene: necrosis with putrefaction
This quiz provides an overview of circulatory disturbances such as hyperemia, congestion, edema, hemorrhage, ischemia, infarction, gangrene, thrombosis, and embolism explained by Dr. Dina Abdallah Elnady. The topics covered include different types of hyperemia and congestion, as well as factors contributing to active hyperemia and passive hyperemia.
