How long is recovery from vascular surgery in the legs/calves?

Depends on procedure: Recovery after any surgical procedure is variable in duration and difficulty. The biggest factors that affect recovery are the procedure itself, your overall health and physical condition, your nutritional status. Some vascular surgery leg procedures are done in an outpatient setting with recovery expected to be less than a week. Some require hospital stay and rehab for recovery.

Recovery time: Procedures done on the inside starting with only a needle puncture have little or no down time. If an open procedure ( a leg bypass for instance) is done 2-4 days in hospital and a month to get back to full speed would be a rough estimate.
