作者：Bendszus et al. (1)是最有趣的。栓塞与手术之间的平均时间为3天。我过去常常在手术台上栓塞脑膜瘤，就在做切口之前，如果可行的话，或者在打开病人并尽可能地将供血动脉与主循环隔离之后（只栓塞被证明为肿瘤供血的外动脉部分）。值得注意的是，我们发现从头皮切口开始的血管手术变得非常干燥，但仅在栓塞后几个小时内。我不相信我们曾经发表过这些观察结果，我也不认为它们是原创的，但最引人注目的是，在肿瘤床栓塞后，头皮向内出血立即减少。这种血管的急剧减少持续了几个小时，当肿瘤被切除时，头皮、颅骨和邻近结构的血管明显恢复。我们相信，栓塞的最大受益是即时的，之后迅速下降。
The article by Bendszus et al.(1) is most interesting. Their mean time between embolization and surgery was 3 days. I used to embolize meningiomas on the operation table just before making the incision, when feasible, or after opening the patient and isolating the feeding arteries from the main circulation as much as possible (embolizing only the portion of the external artery that proved to be feeding the tumor). Significantly, we found that the otherwise vascular operation from the scalp incision onward was rendered remarkably dry, but only for a few hours after embolization. I do not believe we ever published these observations, and I do not think they were original, but it was most dramatic to note the immediate reduction in all bleeding from the scalp inward after embolization of the tumor bed. This dramatic reduction of vascularity lasted several hours, with a noticeable return of vascularity to the scalp, cranium, and adjacent structures when the tumor was removed. We were convinced that the maximum embolization benefit was immediate and rapidly declined thereafter.
