Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms. On the other hand, a persistent trigeminal artery variant feeding both the anterior inferior cerebellar artery and the posterior inferior cerebellar artery territory is very rare. We present this uncommon anomalous artery along with digital subtraction angiography findings and discuss its clinical significance in light of the literature.
永存三叉动脉变异被描述为直接发自颈内动脉海绵窦段的小脑动脉。在 0.18%的脑导管血管造影中观察到了这种情况。另一方面，永存三叉动脉变异同时供应小脑前下动脉和小脑后下动脉区域是非常罕见的。我们展示了这条不常见的异常动脉，并结合数字减影血管造影结果讨论了其在文献中的临床意义。
