Superselective arteriography and therapeutic embolisation for vascular malformations. (Angiodysplasias).

By virtue of superselective arteriography which makes possible the catheterisation of extremely fine arterial branches, the authors were able to embolise vascular malformations (angiodysplasias). Twenty seven cases were treated in this way with satisfactory results for twenty one of them. Seven patients must be operated on after the embolisation. The problem of the future of this technique is considered, and it will perhaps be possible to avoid revascularization by the use of new substances.
