  • Title: Systemic supply to a pulmonary arteriovenous malformation: potential explanation for recurrence.
    Author: Wispelaere JF, Trigaux JP, Weynants P, Delos M, Coene BD.
    Journal: Cardiovasc Intervent Radiol; 1996; 19(4):285-7. PubMed ID: 8755086.
    Abstract:
    A pregnant woman presented with hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) and a single pulmonary arteriovenous malformation (AVM) that had been embolized 5 years previously. Partly due to pregnancy, recanalization of the aneurysm occurred with subsequent hemoptysis. Despite successful therapeutic reembolization of the afferent pulmonary artery, hemoptysis recurred 5 days later. At this time, recanalization of the pulmonary artery was not demonstrated by pulmonary angiography, but a systemic angiogram revealed a bronchial arterial supply to the pulmonary AVM. A systemic supply should always be sought in cases of recurrent hemoptysis after technically successful embolization of the feeding pulmonary artery.
