[Intralesional sclerotherapy of venous malformations in the hand with methyl tetradecyl sulfate].

Congenital venous malformations (VM) at the hand are rare. VM consist of dysplastic venous vessels without progressive cellular proliferation. The therapy for VM is considerably different from that for vascular tumours (e. g., haemangiomas). Treatment options for vascular malformations are antithrombotic medication, local compression, resection of the VM, and obliteration of the lumina by percutaneous sclerosation. Here, the percutaneous sclerosation for the treatment of VM with sodium tetradecyl sulfate has been illustrated and discussed on the basis of 2 case reports.
