This study evaluated fundal arteriole angiographic revascularization after embolization with embolic microspheres of 3 different diameters in a swine model (16 swine, 31 arterioles). In the 50-μm group, 7 of 11 (64%) arterioles recanalized completely, 3 of 11 (27%) arterioles recanalized partially, and 1 of 11 (9%) arterioles had collateralization (no recanalization). In the 100- to 300-μm group, 7 of 10 (70%) arterioles recanalized completely and 3 of 10 (30%) arterioles) recanalized partially. In the 300- to 500-μm group, 7 of 10 (70%) arterioles recanalized completely, 1 of 10 (10%) arterioles recanalized partially, and 2 of 10 (20%) arterioles had collateralization. No difference was found between the groups in the degree of recanalization (P = .64). All embolized arterioles exhibited some degree of angiographic revascularization, irrespective of the microsphere size.
本研究在猪模型中评估了用 3 种不同直径的微球栓塞后的底蜕膜动脉血管再通情况（16 头猪，31 条动脉）。在 50-μm 组中，11 条动脉中的 7 条（64%）完全再通，11 条中的 3 条（27%）部分再通，11 条中的 1 条（9%）有侧支循环（无再通）。在 100-300-μm 组中，10 条动脉中的 7 条（70%）完全再通，10 条中的 3 条（30%）部分再通。在 300-500-μm 组中，10 条动脉中的 7 条（70%）完全再通，10 条中的 1 条（10%）部分再通，10 条中的 2 条（20%）有侧支循环。各组之间的再通程度无差异（P=.64）。无论微球大小如何，所有栓塞的动脉都表现出一定程度的血管造影再通。
