Critical limb ischaemia

When arteries become blocked, slowing or limiting blood flow, it can cause pain and sometimes the loss of a limb. Severe cases of critical limb ischaemia can be life threatening. Around 70% of patients are eligible for surgery; those who are not have had few options other than amputation. But regenerative therapies could change that.
