PURPOSE
The aim of this study was to present a case of basilar artery (BA) formed by persistent primitive trigeminal artery (PPTA), which was diagnosed using digital subtraction angiography (DSA).
DISCUSSION
PPTA is a common branching variation of embryological origin. The prevalence of PPTA ranges between 0.1 and 0.6%. It has been reported that PPTA typically joins the BA proximally and supplies the superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA) or posterior inferior cerebellar artery (PICA) branches. This is the first report of a case where the vertebral artery (VA) terminates in the PICA, and PPTA forms the BA and solely supplies the posterior circulation.
CONCLUSION
No study or case report has been identified in the English literature on persistent primitive trigeminal artery serving as the sole source of blood supply to basilar artery alone.
目的
本研究旨在报告一例基底动脉（BA）由永存原始三叉动脉（PPTA）形成的病例，该病例通过数字减影血管造影（DSA）进行诊断。
讨论
PPTA 是一种常见的胚胎起源的分支变异。PPTA 的发生率在 0.1%至 0.6%之间。据报道，PPTA 通常在近端加入 BA，并供应小脑上动脉（SCA）、小脑前下动脉（AICA）或小脑后下动脉（PICA）分支。这是首例报告椎动脉（VA）终止于 PICA，而 PPTA 形成 BA 并单独供应后循环的病例。
结论
在英文文献中，没有发现关于永存原始三叉动脉作为 BA 唯一供血来源的研究或病例报告。
