PURPOSE
To evaluate the indication and advantages of venous sac embolization of pulmonary arteriovenous malformations (PAVMs) using interlocking detachable coils (IDCs).
METHODS
We performed percutaneous embolization in 12 PAVMs in four patients using IDCs, initially placed in the venous sac or at the feeding artery to prevent systemic migration of additional coils. We placed the IDCs in the venous sac in PAVMs with the following vascular architecture: the draining vein was larger than the feeding arteries and both vessels were interposed with the venous sac or there were short feeding arteries.
RESULTS
Complete occlusion was achieved in all 12 PAVMs without significant complications. We deployed IDCs in the venous sac in eight PAVMs and in the feeding artery in four.
CONCLUSION
Venous sac embolization may be beneficial in PAVMs with large out-flow vessels or short feeding arteries. IDCs are suitable for this procedure.
目的
评估使用可脱卸弹簧圈（IDC）对肺动静脉畸形（PAVM）进行静脉囊栓塞的适应症及优势。
方法
我们对4例患者的12处PAVM采用IDC进行经皮栓塞，最初将其置于静脉囊或供血动脉处，以防止额外弹簧圈发生体循环迁移。对于具有以下血管结构的PAVM，我们将IDC置于静脉囊中：引流静脉大于供血动脉，且两者均与静脉囊相连，或存在短供血动脉。
结果
所有12处PAVM均实现完全闭塞，且无明显并发症。我们在8处PAVM的静脉囊中以及4处PAVM的供血动脉中部署了IDC。
结论
对于具有大流出血管或短供血动脉的PAVM，静脉囊栓塞可能有益。IDC适用于此操作。
