Although anastomoses between the arterial branches arising from the internal carotid artery (ICA) can develop as collateral pathways between the bilateral ICAs in cases of dysgenesis of the ICA, anastomosis of the recurrent arteries branching from the first segment of the ophthalmic artery (OphA) has not been described. Herein, we report two cases of this rare anastomosis. In a 36-year-old man with left segmental dysgenesis of the ICA, an anastomosis between the bilateral ICAs developed around the sella turcica. In a 39-year-old woman with dysgenesis of the bilateral distal ICAs, an anastomosis between the superior hypophyseal trunk and bilateral ICAs was identified. The anastomoses in both cases were also supplied by recurrent arteries branching from the first segment of the OphAs. This is the first report describing recurrent arteries from the OphAs that form the anastomosis between bilateral ICAs.
尽管在颈内动脉（ICA）分支发育不良的情况下，动脉分支之间可能会形成双侧 ICA 之间的侧支通路，但来自眼动脉（OphA）第一段的再分支动脉之间的吻合尚未被描述。在此，我们报告两例这种罕见的吻合。在一名 36 岁的左侧 ICA 节段发育不良的男性中，双侧 ICA 之间在蝶鞍周围形成吻合。在一名 39 岁的双侧远端 ICA 发育不良的女性中，发现垂体上干和双侧 ICA 之间存在吻合。这两个病例的吻合均由来自 OphA 第一段的再分支动脉供应。这是首例描述来自 OphA 的再分支动脉形成双侧 ICA 之间吻合的报告。
