Slender versus threatening angiodysplasias: observe, operate or obturate? A delusive decision.
Beside the immediate success of surgery and of embolization of angiodysplasias, certain number of patients return to medical consultation, because recanalization of the arteriovenous fistulae after their resection or obturation. From the presentation of two clinical cases of thoracic angiodysplasia: one of them slender, and threatening the other, the authors point out the complications and recurrence after surgical resection or arterial embolization. The recurrence takes place even when only one artery remains permeable after resection or embolization of the fistula. There are cases where the affected limb has to be amputated. However, angiodysplasia shows itself in the stump of the amputee limb. Uncontrolled angio-genesis is the natural history or postoperatory evolution of angiodysplasias, probably originated by an erroneous genetic program, which persist in spite of resection of the vascular malformation, causing a therapeutic failure.
