Q

> 95% origin is in deep veins of legs

sudden death, right heart failure, or CV collapse occurs when more than 60% of pulmonary circulation obstructed

16
Q

occludes main pulmonary artier and branches into L and R pulmonary arteries

A

saddle embolus

17
Q

may be multiple and occur over time

pass into smaller branching arteries

tend to be clinically silent
-mulitple emboli over time cause pulmonary hypertension

A

small pulmonary emboli

18
Q

arterial emboli

80% intracardiac mural thrombi

lower extremities and brain affected

A

systemic thromboembolism

19
Q

microscopic fat globules found in circulation after fractures of long bones

A

fat embolism

20
Q

gas bubbles in the circulation can coalesce causing obstruction of vascular flow (ischemia)

small venous gas emboli have no deleterious effects

can enter circulation via:

  • obstetric procedures
  • chest wall injury
  • iatrogenic
  • decompression sickness
A

air embolism

21
Q

grave but uncommon complication of labor and delivery

-sudden severe dyspnea, cyanosis and hypotensive shock

A

amniotic fluid embolus

22
Q

localized area of ischemic necrosis caused by obstruction of arterial supply or venous drainage

A

infarction
