1 MIXED CHRONIC LEG ULCER Palliative treatment results on 132 patients Enrique G. Bertranou Enrique G. Bertranou José Antonio Olivencia José Antonio Olivencia Sergio E. Gonorazky Hospital Privado de Comunidad. Mar del Plata, Argentina Iowa Vein Center. Des Moines, Iowa

2 The similar clinical features of a group of chronic leg ulcer, permit its inclusion under a distinct group called: “mixed chronic leg ulcer” (MCLU) for its better management. INTRODUCTION

3 BRIEF DEFINITION OF THE NEW CLINICAL ENTITY Leg ulcer resulting of chronic, progressive and irreversible impairment of the venous, arteriolar and lymphatic circulation, in aged patients with unbearable pain and remote possibilities of cure.

4 OBJECTIVES Description of mixed chronic leg ulcer Description of mixed chronic leg ulcer(MCLU). Description of the leg ulcer palliative Description of the leg ulcer palliative care program (LUPC). Evaluation of 12 year – leg ulcer palliative Evaluation of 12 year – leg ulcer palliative care program (LUPC). Determination of mixed chronic leg ulcer Determination of mixed chronic leg ulcer survival rate. Survival rate comparison between MCLU Survival rate comparison between MCLU and matched control group.

5 CLINICAL FEATURES Elderly patients. Frequently women. Background of venous and/or arteriolar ulcer. Extensive, profound, necrotic, transudating ulcer. Unbearable pain (mostly by night). Torpid evolution. No peripheral pulses. No foot gangrene. Arterial hypertension. No cognitive deterioration. Remote possibilities of cure.

Treatment cost: $152 patient/month. Treatment cost: $152 patient/month. No survival difference between patients with No survival difference between patients with mixed leg ulcer and general population. RESULTS

17 1)Patient/family compliance of leg ulcer palliative care program resulted in adequate ulcer maintenance and satisfactory pain control. 2) The patient survival rate was high despite the presence of MCLU. 3) No survival rate difference between patients and controls. 4) Leg ulcer palliative care program offer quality of life on these incurable patients. on these incurable patients. 5) MCLU management with complex diagnostic and therapeutic methods is futile.
