Treatment of complicated cavernous venous malformation with retained copper wires combined with pingyangmycin injection / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the therapeutic effect of retained copper wires combined with pingyangmycin (PYM) injection for complicated cavernous venous malformation.</p><p><b>METHODS</b>The location of venous malformation was detected by physical examination and MRI. The copper wires in 0.2 mm width were used to puncture the lesion repeatedly and retained in the lesion to form a net. After that, 8 mg PYM was injected into the residue malformed veins. 8-10 days later, the copper wires were taken out and necrotic tissue was squeezed out. The wounds of punctual holes healed through dressing. The patients received postoperative MRI to evaluate the therapeutic effect.</p><p><b>RESULTS</b>From Jan. 2002 to Dec. 2008, 45 cases were treated. The patients were followed up for 1-3 years. 51.1% (23/45) of the lesions shrinked markedly or even disappeared. 42.2% (19/45) of the lesions reduced. 6.67% (3/45) of the lesions didn't change. There was no complication like invasive infection.</p><p><b>CONCLUSIONS</b>It is very effective to treat complicated cavernous venous malformation with retained copper wires combined with pingyangmycin injection.</p>
