Venous malformations of the lower limb with severe localized intravascular coagulopathy treated with radiofrequency ablation and resection.

Diffuse venous malformations (VMs) are relatively rare, especially the lesions locting special anatomical sites, and they are prone to casuse localized intravascular coagulopathy (LIC). Diffuse VMs can also cause bleeding and life-threatening disseminated intravascular coagulopathy (DIC) from trauma, surgery, and improper treatments. Thus, the treatment of diffuse VMs with LIC is quite tough. We report of a diffuse VMs with severe LIC that was treated with the combined use of minimally invasive treatment and open surgery.
