What to know about arterial and mixed wounds

An arterial ulcer is an open sore that develops because the arteries feeding the leg or foot have narrowed and can no longer carry enough blood to keep skin alive and repair it. Clinicians also call these ischemic wounds. They show up most on the tips of the toes, between the toes, on the heel, over the ankle bone and along the shin, places far from the heart or pressed on by shoes. The sore is often small, deep and dry, with a clean border. A mixed wound, sometimes called a mixed arterial-venous ulcer, sits on a leg where the veins are also failing, so swelling and drainage appear alongside the signs of a poor arterial supply.

How the care plan is built

Bedside findings are often backed up by circulation tests. Depending on the situation, the treating clinician may order or request results from:

  • An ankle-brachial index, which compares blood pressure at the ankle and the arm
  • Toe pressures, often used when ankle arteries are too stiff to give a reliable reading
  • An arterial ultrasound that maps where flow narrows
  • A skin oxygen measurement near the wound

The numbers answer practical questions: whether the wound has a reasonable chance of closing with local care, whether a vascular specialist should be involved soon, and how much compression, if any, a swollen leg can tolerate.

Local context: University City

People in University City often move between settings without going far: a hospital stay for a vascular procedure, a few weeks in a nearby skilled nursing or rehabilitation center, then home or to a senior living community close by. An arterial wound has to be followed through each move, and orders about compression, dressings and weight on the foot must travel with it. Gateway keeps the wound records and the treating clinician’s current orders together across those handoffs, so each new nursing team starts from the same plan and the family is not left carrying paperwork.

Homes in University City are mostly older: brick houses with front steps and second-floor bedrooms, two-family flats, and apartment and condominium buildings, some with elevators and some without. Senior apartments, assisted living and skilled nursing care are found within the city or a short drive away. Gateway arranges visits with partner clinicians in all of these places. When you call, mention details such as a buzzer entry, a walk-up floor or street-only parking, so the clinician knows what to expect on arrival.

Care at home

At a home visit, the treating clinician sees things a clinic never shows: the shoes by the door, the chair where you spend the afternoon, the bed where a heel rests all night. For an arterial wound those details matter, because pressure and rubbing on a poorly supplied foot can undo careful dressing work.

Gateway schedules the visit, gathers earlier vascular records and test results beforehand, and sends the clinician’s orders where they need to go afterward. For people whose leg pain limits walking, being seen at home removes the hardest part of getting care, which is the trip.

For residents of nursing and senior living communities

In a skilled nursing facility, partner clinicians see residents with arterial or mixed wounds on site and write recommendations for the attending physician and nursing staff. Facility nurses carry out the daily dressing orders and are well placed to catch change early, since they see the foot every shift.

Gateway coordinates the visit schedule with the director of nursing or wound nurse, sends visit notes for the chart, and tracks open items such as a pending circulation test. Clear documentation of whether compression is ordered for each leg matters here, because staff rotate and a routine wrap on the wrong leg is an avoidable error.

Changes to report

Arterial wounds can change quietly, so small differences are worth a call. Contact the treating clinician’s team promptly if you notice:

  • Pain that is stronger, or that now wakes you at night
  • A toe or patch of skin turning dusky, purple or black
  • The wound getting wider or deeper
  • New drainage or odor, or a dry scab turning soft
  • Redness or warmth spreading out from the wound

Call 911 if a foot or leg suddenly turns cold, pale or blue, goes numb, or becomes severely painful or hard to move. A sudden loss of blood flow is an emergency.

Why primary care matters here

People with arterial or mixed wounds often take a long list of medications: for blood pressure, cholesterol, diabetes, heart rhythm, fluid and pain. Some affect swelling, some affect bleeding at the wound, and pain medicine may need review as the wound changes. Only the prescribing clinician should adjust any of them, which is one reason a current primary care relationship matters.

A primary care visit at home can include a full medication review. Gateway then sends the updated list to the wound care clinician and any vascular office involved, ahead of the next appointment or procedure.

Arranging arterial and mixed wound care in University City

Before anything is scheduled, Gateway checks two things for every request for arterial and mixed wound care in University City: whether a partner clinician serves that address and care setting, and what the patient’s plan requires from the treating provider. Neither is assumed. If both line up, we arrange the visit and gather records. If something stands in the way, we say so, and our guide to following up on a request explains what to ask next. Gateway coordinates the care and does not make clinical decisions. Those belong to the treating clinician who sees the wound. Start by calling 314-325-0126, or ask a family member to call for you.

A few things make a University City request go smoothly. Have the street address and unit number, a phone number that will be answered, the name of the regular doctor and any hospital paperwork. Tell us about stairs, locked entries and where a visitor can park. Gateway also coordinates care nearby in Clayton and Central County, Overland, the Central West End, Ladue and Creve Coeur. Availability is confirmed by location and care setting, so we will ask whether the patient is at home or in a facility.

Common questions

Can a wound care clinician come to a home in University City to look at an arterial ulcer?

Gateway arranges home visits from partner clinicians for arterial and mixed wounds, and availability is confirmed by location and care setting. Call 314-325-0126 or send a callback request with your name and phone number. We will ask where in University City the patient lives, what kind of home or facility it is, and whether any vascular records exist, then explain what happens next.

What should I have ready before the first visit for an arterial or mixed wound?

Helpful items include a current medication list, the names of your primary care clinician and any vascular or heart specialists, and results of past circulation tests or leg procedures if you have them. Set out the shoes and slippers you wear most. Write down when the wound started and when pain is worst. Gateway can request outside records for the treating clinician, so missing paperwork is no reason to delay calling.

Should I keep my legs up or down with an arterial or mixed wound?

It depends on your circulation, so this is a question for the treating clinician. Raising the legs helps vein-related swelling but can increase pain when arterial flow is low. Letting the legs hang can ease arterial pain but adds swelling. With a mixed wound, both effects are in play. The clinician can suggest positions for sitting and sleeping based on your test results and symptoms.

My father in University City no longer drives. Can primary care come to his house?

It can be arranged. Gateway connects people who cannot easily get to an office with partner clinicians who provide primary care follow-up at home. Call 314-325-0126 with his address and phone number. We will ask a few questions, confirm availability for his part of University City and request records from his current doctors.
