Case Study: Diabetic Ulcer Healing
The color bar can be used to quickly identify
different regions of tissue oxygenation that then can be quantified
by using the HyperVu software. HT-oxy levels are related to color
changes (low to high, yellow to purple) – HT-deoxy levels
are related to brightness (low to high, pale to brilliant).
This 43 year old Indian female with type I diabetes with an ulcer
of the sub hallux interphalangeal joint of the right foot was
followed for 1 year. She also had diagnoses of hyperlipidemia,
hypertension, hypothyroidism and peripheral neuropathy. She had
been admitted two months previously for acute cellulitis of the
right foot and diagnosed with osteomyelitis of the right hallux
distal and proximal phallanx by MRI and bone scan. She had been
treated with IV ertapenem for 6 weeks followed by oral antibiotics.
The ulcer can be seen to be largely healed one month later.
A positive HTcOM Healing Index around the ulcer at the first
visit was consistent with healing wounds and would support continued
conservative therapy. In other subjects, a negative HTcOM Healing
Index was associated with non-healing and would support a more
aggressive approach including offloading, hyperbaric therapy,
or angiography and revascularization.
