肺动静脉畸形的再栓塞治疗

肺动静脉畸形右向左分流的治疗是通过栓塞治疗（Pulmonary Arteriovenous Malformations are R→L shunts treated with embolotherapy）

大约25%的被治疗的肺动静脉畸形CT随访过程中仍然持续存在动静脉血管团的显影（Up to 25% of treated PAVMs have persistent sac filling at CT follow up）

这是由于（被栓塞）肺动脉再通，邻近肺动脉再灌注，或通过全身侧支循环以及仍然未治疗的供血动脉再灌注

• Attributed to recanalization, reperfusion via adjacent pulmonary arteries, reperfusion via systemic collaterals, or remaining untreated feeders

定义

定义	描述	示意图
再通（Recanalization）:	灌注来自穿过以前放置的弹簧栓子巢的血流（Perfusion by flow through a previously placed coil nest）
再灌注（Reperfusion）:	通过邻近肺动脉小的侧支动脉（Perfusion through small collateral feeders from adjacent pulmonary arteries）
初次治疗不完全（Incomplete primary treatment: ）	灌注来自以前未治疗的复杂动静脉畸形供血动脉（Perfusion through previously untreated feeders of a complex PAVM）
