Histologic findings in 71 elastase-induced rabbit aneurysms embolized with platinum coils were retrospectively reviewed. Mature bone formation was found in 2 aneurysms, one with coils implanted for 3 months and the other with coils implanted for 1 year. We present the histologic findings and offer potential explanations for these observations. These findings may be relevant in understanding mechanisms of aneurysm healing after coil embolization.
回顾性分析了71只用铂弹簧圈栓塞的弹性蛋白酶诱导的兔动脉瘤的组织学结果。在2个动脉瘤中发现了成熟骨形成,其中一个动脉瘤的弹簧圈植入了3个月,另一个植入了1年。我们展示了组织学结果并对这些观察结果提供了可能的解释。这些结果可能与理解弹簧圈栓塞后动脉瘤愈合的机制相关。
