HEMODYNAMIC DISEASE II TERMS

Question 1

maintenance of the blood in a fluid clot free state in normal vessels

poised to induce a rapid and localized and localized hemostatic plug at a site of vascular injury

Answer 1

normal hemostasis

Question 2

pathology of hemostasis; formation of clotted mass of blood constituents in uninterrupted vascular system

Answer 2

thrombosis

Question 3

retarded flow of blood (especially in veins but also in arteries causes aneurysms or LV diastasic)

Answer 3

stasis

Question 4

activation of platelets
endothelial injury
retards inflow of inhibitors

Answer 4

turbulence

Question 5

pale platelet and fibrin deposits alternating with darker red cell-rich layers

Answer 5

lines of zahn

Question 6

thrombi accumulate additional platelets and fibrin

Answer 6

propagation

Question 7

thrombi dislodge and travel other sites in the vasculature

Answer 7

embolization

Question 8

result in fibrinolysis which lead to rapid and shrinkage and total disappearance of recent thrombi?

Answer 8

dissolution

Question 9

older thrombi become organized by ingrowth of endothelial cells, SM cells and fibroblasts

Answer 9

organization

Question 10

most occur in superficial and deep veins of the leg

Answer 10

venous thrombosis

Question 11

cause local problems but rarely embolism

Answer 11

superficial venous thrombosis

Question 12

more likely to embolize to the lungs and gives rise to pulmonary infarction

Answer 12

deep venous thrombosis

Question 13

common cause of death, assoc. with atherosclerosis

Answer 13

arterial thrombosis

Question 14

detached intravascular solid, liquid, or gaseous mass

Answer 14

embolism

Question 15

> 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

Answer 15

pulmonary embolism

Question 16

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

Answer 16

saddle embolus

Question 17

may be multiple and occur over time

pass into smaller branching arteries

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

Answer 17

small pulmonary emboli

Question 18

arterial emboli

80% intracardiac mural thrombi

lower extremities and brain affected

Answer 18

systemic thromboembolism

Question 19

microscopic fat globules found in circulation after fractures of long bones

Answer 19

fat embolism

Question 20

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

Answer 20

air embolism

Question 21

grave but uncommon complication of labor and delivery

-sudden severe dyspnea, cyanosis and hypotensive shock

Answer 21

amniotic fluid embolus

Question 22

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

Answer 22

infarction
