Hemodynamic dysorder & Shock Flashcards
Embolism definition
free moving intravascular mass carried from 1 spot to another.
Types of Emboli
1-2
1) thromboemboli: venous or arterial. Can have infection thrombi = septic emboli (viridans)
2) Liquid Emboli: Fat emboli after bone fracture, Amniotic fluid into uterine veins.
Pulmonary emboli
50,000 - 70,000 deaths per year. Heprin = anticoagulant. Chronic clot = umbrella or shunt IVC
Saddle thromboembolus
Primary Pulmonary embolis
Mural thrombus
Arterial embolus; endocardium asterial side (Brain strokes, spleen, kidney, mesentaric (dead bowel), lower extremities (gangrene)
venous thrombus leads to
pulmonary embolis
Acute bacterial endocarditis
Staph aureus, Stroke and abscess
Fat embolism in
Pulmonary artery
Embolism types
3-4
3) Gaseous emboli- air embolism injecting air into veins, decompressoin sickness .
4) Solid Particle Emboli: Cholesterol crystals from atherosclerotic plaques from tumor or bone marrow.
RCC spreads by embolis
Bone marrow embolis = CPR broken rib particle.
Most common Emboli
Venouse Embolism final destination?
Thromboemboli
Pulmonary Artery (from right ventricle)
Sources of Venous emboli
Tumor (RCC), Amniotic, Deep Vein, Saddle, Infaction, Fracture with fat.
Arterial Emboli originate and destination and causes
From L. atrium, ventricle, or aorta. Via arterial blood to peripheral arteries.
Causes: endocardium or valvular thrombi. results in ischemia or bacterial emboli (S. aureus). Other sources are ulerated atherosclerotic plaques from aorta
Paradoxical emboli
Via foreman ovale
Venous embolism that enter arterial circulation via foreman ovale or Interventricular spetal defect. Bypass lungs
Arterial Embolism, what sized arteris are involved?
Medium or smaller arteries recieved larger arterial plaques.
Mural thrombus - endocardium
heart quivers, builds up a clot, and clot leaves the heart with a return to normal rhythm.
