We investigated the efficacy of steel coils for embolotherapy of pulmonary arteriovenous malformations (PAVMs) by reimaging the embolized PAVMs.
We found a high incidence (57%; 8/14) of recanalization in PAVMs embolized with steel coils. Contrast-enhanced CT is useful for detection of recanalized PAVMs. Half of the recanalized PAVMs were fed by bronchial artery branches. Thus, coil embolization should be performed as close as possible to the PAVM to avoid future development of bronchial artery-to-pulmonary artery anastomoses that may cause recanalization.
通过对栓塞后的肺动静脉畸形（PAVM）进行再次成像，研究钢圈在PAVM栓塞治疗中的疗效。
我们发现用钢圈栓塞的PAVM再通发生率很高（57%；8/14）。对比增强CT有助于检测再通的PAVM。一半再通的PAVM由支气管动脉分支供血。因此，应尽可能靠近PAVM进行钢圈栓塞，以避免未来可能导致再通的支气管动脉至肺动脉吻合的发展。
