A 52 year old obese female presents to the outpatient wound clinic complaining of a 3 week history of a draining wound to her right lower extremity. She states she believes the wound began as a bug bite, and has gradually been increasing in size. She states the wound pain is worse in the evening, and the wound feels better when she has her leg elevated. Upon inspecting her right leg you note a 3x3cm ulceration to the medial peri-malleolar area.
Based on the patient presentation this wound is most likely:
You note that around 74% of venous leg ulcers begin with a trigger event such as bug bite, that her wound pain is relieved with elevation, and that the wound is located in her peri-malleolar space. The patient is diagnosed with a venous leg ulcer, and you decide to begin compression therapy. An important intervention prior to selecting compression therapy for this patient is:
You order an ankle brachial index to determine whether the patient’s arterial status can tolerate the recommended 30-40mmHg to heal and prevent venous leg ulcers. The patient’s results are: Right ABI 0.7 and Right TBI 0.5. The patient denies any calf pain with elevation or activity. Given these results the correct level of compression would be:
Based on the patient ABI result 0.5-0.8 and TBI <0.7 you decide to trial the patient in 20-30mmHg compression. Prior to initiating treatment the patient points to her right lateral ankle indicating a patch of white atrophic skin with small red dots within. There is no drainage from the lesion. She asks what the spot is and if it’s still safe to apply the compression wrap. You explain to the patient that the lesion is likely:
You explain that the lesion is likely atrophie blanch, and that the red spots are tiny dilated capillaries. You teach her to monitor the lesion as this can be a source of a new ulceration, and is another reason why she should begin to wear compression every day. Once the ulcer has healed education for application of her new compression stockings should include:
