Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Severity of acute limb ischemia ____ Sensory loss involves more than the toes and may be associated with rest pain. There is mild-to-moderate muscle weakness, arterial Doppler signals are usually inaudible, and venous Doppler signals are audible.

A	Stage I
B	Stage IIa
C	Stage IIb
D	Stage III

Explanation:

Detailed explanation-1: -Causes. Most acute limb ischemia is caused by embolism (30% of the cases), thrombosis (40% of the cases), thrombosis by popliteal artery aneurysm (5%), major trauma (5%) and vascular graft thrombosis (20%).

Detailed explanation-2: -What is critical limb ischemia? Critical limb ischemia (CLI) is a severe blockage in the arteries of the lower extremities, which markedly reduces blood-flow. It is a serious form of peripheral arterial disease, or PAD, but less common than claudication.
