Endovascular embolisation strategies for pulmonary arteriovenous malformations

PURPOSE: To assess the immediate efficacy of distinct embolisation devices in the endovascular treatment of pulmonary arteriovenous malformations as well as to identify and analyse the possible determinants of the technical success of the procedure. MATERIAL AND METHODS: Prospective analysis of 16 c...

description PURPOSE: To assess the immediate efficacy of distinct embolisation devices in the endovascular treatment of pulmonary arteriovenous malformations as well as to identify and analyse the possible determinants of the technical success of the procedure. MATERIAL AND METHODS: Prospective analysis of 16 consecutive patients was carried out, who underwent transcatheter endovascular embolisation therapy for pulmonary arteriovenous malformations between 2005 and 2017. Pre- and post-procedural angiography studies were implemented to confirm the diagnosis and to evaluate the technical success defined as the complete occlusion of the feeding artery. Embolisation devices – coils, microcoils, occluders, or combination of the above – were used. All the patients were advised to conduct a follow-up computed tomography evaluation 12 months after the procedure. RESULTS: A total of 40 pulmonary arteriovenous malformations (PAVMs) were observed and embolised. The immediate technical success was achieved in all (n = 40; 100%) treated PAVMs, as confirmed by the post-procedural angiographic result. The statistical analysis revealed no significant impact of the number of PAVMs per patient (p > 0.05), their angioarchitecture (p > 0.05), localisation within the lung (p > 0.05) or particular lobe (p > 0.05), and the selection of embolisation device (p > 0.05) on the procedural success rates. The procedure-related complication rate was equal to 6.25%. CONCLUSIONS: The immediate success rate of the transcatheter PAVM embolisation reached 100% in this study. The statistical model of logistic regression revealed no significant impact of the number of PAVMs per patient, their angioarchitecture, localisation, and distribution pattern, as well as device selection, on the immediate technical success of the procedure.
