[Vascular dysplasias of the hand].

The author presents 4 cases of angiodysplasia of the hand. The first is an angioma of the thumb, with active arteriovenous communications, leading the author to analyze the difficulties inherent in the surgical treatment of cirsoid aneurysms. The second is a limited digital arteriovenous angioma, this group being easily operable. The remaining two are extensive angiomas, one treated by embolization followed by sclerosis of the remaining venous lakes, and the other by embolization followed by surgical removal of the part of the angioma which was not collapsed. These cases demonstrate the major value of embolization. This prepares for and facilitates surgery, and, alone or associated with surgery, now permits a lasting cure of this type of lesion while avoiding the risks of surgical treatment alone.
