Proper selection of patients for percutaneous embolo-sclerotherapy in patients with congenital vascular malformations (CVMs).

For the treatment of congenital vascular malformation (CVM), conservative, endovascular and/or surgical treatment have been sporadically attempted according to the type, location and clinical manifestations of the vascular lesions. At current practice, with no established treatment guidelines for CVM patients, there is much room for ineffective interventions and occurrence of complications related with the treatment. Therefore, it is important to select proper candidates for the endovascular or surgical treatment in CVM patients to avoid ineffective treatment and its complications and to obtain better treatment results. We describe the basic considerations before the selection of candidates for percutaneous embolo-sclerotherapy in patients with CVM based on our own experiences at a specialised CVM clinic.
