16
Q

What are the diagnostics for acute arterial occlusion PVD?

A
  • Physical exam

- Blood flow assessment via doppler or you can do a angiogram

17
Q

Why do you do a blood flow assessment in acute arterial occlusion PVD?

A

Because you need to confirm blood flow

18
Q

What are the treatment options for acute arterial occlusion PVD?

A
  • thrombolytic
  • anticoagulant
  • surgery
19
Q

Thrombolytic?

A

drug that breaks down thrombus or clot

20
Q

Anticoagulant?

A

Prevents further coagulation

21
Q

When is surgery used as an intervention to treat acute arterial occlusion PVD?

A

It is used as an intervention when thrombolytics and anticoagulants do not work.
