Abstract

Purpose: Ophthalmic artery (OphA) embryogenesis is a complex process with various origins. We describe herein a case in which the OphA stemmed from the persistent primitive trigeminal artery (PPTA), which has never been reported.

Methods: A man in his 70s was admitted to our hospital following the sudden onset of altered consciousness. A computed tomography (CT) scan revealed a cerebellar hemorrhage, brainstem compression, and hydrocephalus. The patient underwent emergency craniotomy for hematoma evacuation and decompression. Digital subtraction angiography (DSA) was performed 14 days postoperatively to determine the source of the bleeding.

Results: DSA of the right vertebral artery revealed retrograde filling of the left PPTA, originating from the distal two-thirds of the basilar artery (BA) and extending to the cavernous segment of the left internal carotid artery (ICA) as well as a small artery extending from the intermediate part of the PPTA into the orbit and passing through the superior orbital fissure (SOF). DSA of the left common carotid artery showed the typical supracavernous origin of the OphA.

Conclusion: This is the first reported case of double OphAs originating from the ICA and PPTA. It is possible that the OphA traversing the SOF had an anastomosis with the primitive trigeminal artery (PTA) during the embryonic period. Persistence of only the BA side of the PTA results in the OphA originating from the BA, whereas persistence of only the ICA side results in the OphA originating from the meningohypophyseal trunk.

双眼动脉起源于颈内动脉和持久的原始三叉动脉。

目的：眼动脉（OphA）胚胎发生是一个复杂的过程，具有多种起源。我们在此描述了一个病例，其中OphA源于持久的原始三叉动脉（PPTA），这从未被报道过。方法：一位70多岁的老人因突然发生意识改变而入院。计算机断层扫描（CT）显示小脑出血，脑干压迫和脑积水。病人接受了紧急开颅手术以清除血肿和减压。术后14天行数字减影血管造影（DSA）确定出血来源。结果：右侧椎动脉DSA显示左侧PPTA逆行充盈，起源于基底动脉（BA）远端三分之二延伸至左侧颈内动脉（ICA）的海绵状段，以及PPTA中间部分延伸至眶上裂（SOF）的小动脉。左侧颈总动脉DSA显示典型的海绵体上起源的OphA。结论：这是首次报道的起源于ICA和PPTA的双OphAs病例。可能在胚胎时期，横过sofa的OphA与原始三叉动脉（PTA）有吻合。只有PTA的BA侧的持续存在导致起源于BA的OphA，而只有ICA侧的持续存在导致起源于脑膜垂体干的OphA。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
