Effects of Compression in Mixed Ulcers (ULCEREMIXTE)
About 15% to 30% of patients with venous leg ulcers have a peripheral arterial disease (PAD) associated. The compression band is still a controversial issue in this context. It allows the reduction of venous hypertension and edema, but it could potentially degrade the arterial infusion of high levels of compression. The French High Authority for Health (HAS) defines mixed ulcers by IPS between 0.5 and 0.9. Investigators distinguish mixed ulcers blood predominance for IPS between 0.5 and 0.7; and mixed ulcers predominantly venous blood with moderate involvement for IPS values between 0.7 and 0.9.
Several studies have shown that IPS> 0.8 allowed a high compression, between 30 and 40 mmHg. In the case of mixed ulcers with IPS between 0.6 and 0.8, the HAS recommends using a lighter compression, bit by elastic bands (exercising low power compression at rest) under medical supervision, informing the patient to remove the bandage if pain or aggravation. It is therefore necessary to adapt the compression therapy in case of venous ulcers associated with arterial disease by providing a lower compression 30 mmHg short stretch. For HAS, IPS <0.6 against indicates compression.
A recent study showed that compression bit elastic bands could not only improve venous return, but it would also increase the distal arterial flow in a patient population with mixed ulcers. In this study, 25 patients had between IPS 0.5 and 0.8; or for certain patients below the threshold of 0.6 indicates that against a compression according to HAS. To our knowledge this is the only study that has examined the effect of compression on blood perfusion.

Detaljeret beskrivelse
Objectives:
- Principal: Study the distal arterial infusion in a patient population with mixed ulcers under compression leg with little elastic bands
- Secondary: To evaluate the safety of the little compression elastic band in a mixed population of patients with leg ulcers
Methodology :
- Study non-interventional prospective single-center that evaluates professional practice from 25 patients with mixed leg ulcers and followed in the vascular medicine department of St. Joseph Hospital Group Paris.
- Applying a bit compression elastic bandages to a pressure level between 30 and 40mmHg.
Anonymous data reports on the grid standardized collection, by a numbering system from 1 to 30 and then captured on a computer file
- Age, risk factors and cardiovascular history of the patients,
- Age, ulcer description
- Palpation of pulse
- morphological vascular profile of patients with arterial and venous Doppler dating less than a year,
Series following data before installation, 10 minutes after application and 24 hours after installation of the inelastic compression:
o Evaluation of tolerance:
- measurement of pain numeric scale (NS)
description of the skin condition of the leg by a dermatologist, seeking signs of suffering skin after application of compression: possible appearance of erythema, cyanosis, purpura. A search particularly in areas of bony prominences and the banks of the ulcer.
o distal arterial pressures of the compression carrier leg:
- IPS (systolic pressure index): ankle and arm pressures will be measured with a cuff and a continuous Doppler. GPI is calculated by dividing the lowest pressure at the ankle (at the dorsalis pedis or posterior tibial artery) by the humeral pressure.
- Transcutaneous Oxygen Pressure (TcPO2) o Measuring pressure exerted by low elastic bandages by Kikuhime® system.
In case of bad tolerance of compression at any time after installation, the compression will be removed and the study stopped for the patient in question. Poor tolerance is defined by an increase in pain than or equal to 2 points on the digital scale.
expected benefits for patients:
- Demonstration of good tolerance, defined as no worsening of the skin condition and the lack of increase in pain associated with inelastic compression.
- Demonstration of no worsening of arterial infusion by inelastic compression.
- Evidence of improved distal arterial hemodynamics (increased IPS and tcpO2) with a little elastic compression, which validate the results of the only study ever conducted on the subject.

Exclusion Criteria:
- Topics aged under 18,
- A normal IPS that is to say between 0.9 and 1.3, a critical ischemia (defined as ankle pressure <70 mmHg and / or systolic pressure of the big toe <50 mmHg)
