RESUMO
<p><b>OBJECTIVE</b>To investigate the clinical effect of electrochemical therapy (ECT) combined with pingyangmycin (PYM) injection for the treatment of high-return flow venous malformation.</p><p><b>METHODS</b>A total of 68 cases of the high-return flow venous malformation were retrospectively analyzed, in which 32 cases received simplely ECT,and 36 cases received ECT combined with PYM injection. The patients were followed up from 6 to 30 months.</p><p><b>RESULTS</b>The effectiveness of ECT was 78% (25/32), and of ECT combined with PYM injection was 97% (35/36). The effectiveness of ECT combined with PYM injection was higher than that of ECT (P < 0.05). No serious adverse effects were encountered.</p><p><b>CONCLUSIONS</b>ECT combined with PYM injection is an effective method for the treatment of high-return flow venous malformation.</p>
