Ulcers Caused by Poor Blood Flow

An ulcer caused by poor blood flow is judged by whether anyone looked at the blood supply, not only at the wound. This article sets out what a sound plan asks and what a shortcut skips.

The condition and the standard

MedlinePlus says ischemic ulcers (wounds) can occur when there is poor blood flow in your legs, or, much less often, other body parts. MedlinePlus adds that poor blood flow causes cells to die and damages tissue. The standard follows from that: if blood flow is the cause, treatment has to address blood flow and not only the wound it produced. For the wider setting of these ulcers, read the American Diabetes Association's page on foot complications.

Signs the standard is being met, and signs it is not

The standard is being met when someone has named blood flow as a question and the plan says how it will be checked. It is not being met when the wound has been dressed visit after visit and nobody has mentioned circulation.

The shortcut and what it costs

The shortcut is treating the wound as a surface problem. Because poor blood flow damages tissue, a dressing without a circulation question treats the visible damage while the cause stays in place. Cleveland Clinic's page on poor circulation: symptoms, causes and treatment lays out the basics, and it is worth reading before a visit where circulation has not come up.

What adequate follow-up looks like

Follow-up should keep returning to the cause. Each visit should record whether the wound is changing and what has been done about blood flow. If the honest answer to the second item is nothing, ask why.

The one check to make

At the next visit, ask one question: what is being done about blood flow in this foot? Write the answer down. If you want a reference text beside you, a PubMed Central (NIH) article titled Diabetic foot is available.
