AIM: Mechanical edema (MO) is frequently found in a lot of the lower extremities' orthopedic diseases. In absence of deep vein thrombosis, MO is caused by the change in the dynamics of calf muscle pump with venous hypertension and by the change in capillary permeability which offsets the extra-vascular fluid balance resulting in edema formation. The correct treatment includes specific training for musculo-skeletal and gait recovery, together with medical treatment focused on venous endothelium. Little information is available about pharmacological treatment of this condition. Some studies suggest the efficacy of mesoglycan in venous pathology. Aim of this study was to evaluate the clinical efficacy of the pharmacological treatment (mesoglycan 50 mg p.o., twice a day) in patients affected by MO.
METHODS: Forty-four patients with MO, aged 20-89 years, were randomized in two treatment groups: specific physiotherapy (Fkt) alone or physiotherapy plus mesoglycan 50 mg twice a day, per os. The patients were evaluated before treatment (t0), and after 1 month of treatment (t1), measuring ankle joint range of motion (degrees), calf circumference and malleolar circumference (cm), pain Borg CR10 Scale and adapted lymphedema Weiss Scale. Statistical analysis was performed by the Pearson's c2 test and the Mann-Whitney-Wilcoxon test.
RESULTS: At the final evaluation of the objective and subjective parameters, the mesoglycan effect combined to the Fkt provided statistical differences on nearly all the parameters in comparison with the patients randomised to Fkt alone.
CONCLUSIONS: The present study suggest that mesoglycan treatment (50 mg p.o., twice a day) can improve the recovery of MO, and it is well tolerated by the patients. Specific physiotherapy remains the first treatment for the recovery of both muscular pump and correct walking, but the optimal treatment of MO seems to be a synergic approach, including both pharmacological and mobilization programs.
