[Clinical treatment of venous malformations with retained copper needles].

UNLABELLED: OBJECTIVE; To evaluate a technique with retained copper needles for the treatment of venous malformations. METHODS: With 78 venous malformation cases, there were three methods were applied for the treatment respectively, including copper needles in the lesion only, vascular ligation with the copper needles in the lesion, and electrical puncture with the copper needles in the lesion. RESULTS: There were totally 96% effective rate achieved in this clinical data. CONCLUSIONS: The retained copper needles technique may be a simple and effective method for the treatment of venous, malformations resulting in vessel denaturation, fibrosis and disappearance of structure.
