In arterial insufficiency, edema is typically what?

Explanation:
The main concept is that arterial insufficiency causes ischemia, not fluid buildup. Edema arises when fluid leaks into tissues due to venous hypertension or lymphatic obstruction, or from systemic factors like heart failure. With arterial disease, arterial inflow is reduced, and capillary hydrostatic pressure isn’t elevated to drive edema, so edema tends to be absent or minimal. If edema is present, it usually points to concurrent venous disease or other conditions rather than pure arterial insufficiency.
