Abstract

A 50-year-old woman reported to the emergency department with thunderclap headache and vomiting. Non-enhanced brain computed tomography (CT) showed a subarachnoid hemorrhage of Hunt-Hess Grade II and Fisher Grade III. Brain angiography CT and transfemoral cerebral angiography (TFCA) revealed an aneurysm of the anterior communicating artery. A direct neck clipping was performed using the pterional approach. The post-operation CT was uneventful. Six days postoperatively, the patient became lethargic. The mean velocity (cm/s) of the middle cerebral artery peaked at 173 cm/s on the right side and 167 cm/s on the left. A TFCA revealed decreased perfusion in both recurrent arteries of Heubner (RAH), but no occlusion in either. Intra-arterial nimodipine injection was administered. On the 7th postoperative day, CT demonstrated a newly developed low-density lesion in the RAH territory bilaterally. The cause of the infarction was attributed to decreased perfusion caused by cerebral vasospasm. The patient was discharged with no definite neurologic deficit except for mild cognitive disorder.

Figures

Fig. 1
Fig. 1. A 50-year-old woman reported at the emergency department with thunderclap headache and vomiting. (A) A non-enhanced brain computed tomography (CT) showed a subarachnoid hemorrhage in the suprasellar cistern, both sylvian and interhemispheric fissure. (B) Brain angiography CT revealed an aneurysm of the anterior communicating artery. The aneurysm was left dominant, inferior in direction, and multi-lobulated.
Fig. 2
Fig. 2. A transfemoral cerebral angiography was performed pre operatively. (A, B) TThe recurrent artery of Heubner (RAH) (arrows) originated bilaterally from the junction of the anterior cerebral artery and the anterior communicating artery. The mean diameter of right and left RAH was 8 mm and 4 mm, respectively.
Fig. 3
Fig. 3. (A) Both the recurrent artery of Heubner (RAH) (arrows) were evidently visible on the pre-operative transfemoral cerebral angiography (TFCA). (B) On the TFCA performed 6 days postoperatively before chemical angioplasty, a blurred right RAH (arrowhead) was seen due to decreased perfusion. The left RAH (arrow) was not visible. (C) On the TFCA performed after chemical angioplasty, the perfusion of right RAH (arrowhead) improved and left RAH (arrow) was visible.
Fig. 4
Fig. 4. (A) A 7-day postoperative follow-up brain computed tomography (CT) showed a newly developed low density lesion in the recurrent artery of Heubner (RAH) territory bilaterally, caudate nucleus, anterior portion of basal ganglia, and internal capsule. (B) The 14-day postoperative follow-up brain CT showed no progression of the low density lesion. The low density lesion in both of the RAH territory was blurred.
