A clinical study of pingyangmycin sclerotherapy for venous malformation: an evaluation of 281 consecutive patients.


PMID 24924412

Abstract

In China, lidocaine together with 2xa0mg/mL of pingyangmycin (PYM, also known as bleomycin A5) is recommended for the treatment of venous malformations (VMs). The purpose of this study was to investigate whether lidocaine has a synergistic effect with PYM in improving the therapeutic outcomes of patients with VMs. Additionally, this study aimed to evaluate the outcomes of sclerotherapy for VMs using an intralesional injection of a low concentration of PYM (0·5xa0mg/mL). A total of 281 patients with VMs were treated with 0·5 or 2xa0mg/mL of PYM with or without lidocaine and dexamethasone (DEX). All of the patients received a direct intralesional injection at a rate of 1xa0mL/min, and the volume of the solution varied from 1·5 to 6·0xa0mL per injection. No significant differences were observed in the clinical outcomes between the PYM and PYMxa0+xa0lidocaine treatment groups (Pxa0>xa00·05). The clinical outcomes were similar between the groups that were treated with 0·5 and 2xa0mg/mL of PYM, but the swelling and pain in the patients who were treated with 0·5xa0mg/mL of PYM were less severe compared with the patients who were treated with 2xa0mg/mL of PYM. A total of 29 patients with VM lesions on the glans penis were treated with 0·5xa0mg/mL of PYMxa0+xa00·5% lidocaine. Of these patients, 26 were cured, whereas three experienced a marked improvement. Lidocaine does not have a synergistic effect with PYM in improving the therapeutic outcomes of patients with VMs. Sclerotherapy with a low concentration of PYM (0·5xa0mg/mL) combined with lidocaine and DEX is a safe and effective therapy for small superficial VMs of critical organs, such as the lips and the glans penis.
