I am Mysticdoc, experienced Internal Medicine Specialist.
I am here to help you with your concerns.
Sorry to hear about your mother's condition.
Leg ulcer can be caused by the poor blood circulation.
Hence this should be checked out by the vascular surgeon with doppler ultrasound.
Ct angiogram is another good option to check for blood circulation.
Non healing ulcer is due to the poor blood circulation in the wound.
One good option to treat non healing ulcer is to consider hyperbaric oxygen therapy.
Wound vac is another good option.
These options can be discussed with the vascular surgeon.
Unna boot is a specialized dressing material containing zinc oxide, calamine and other materials which can also promote healing of the ulcer over time.
