title: Reperfusion of complex pulmonary arteriovenous malformations after embolization: report of three cases.
abstract: The purpose of this report is to discuss the different mechanisms of reperfusion of pulmonary arteriovenous malformations (PAVMs) after embolization. Transcatheter embolotherapy is currently the first-line treatment of PAVMs to prevent neurologic complications or pulmonary hemorrhage. Initial good results can be expected but we report three cases of reperfusion of complex large PAVMs after coil embolization. After adequate embolization, reperfusion of PAVMs may occur by several mechanisms including recanalization of embolized arteries, recruitment of normal arterial branches, growth or enlargement and development of a systemic arterial supply.
