Objective: Most large-vessel occlusions (LVOs) amenable to acute recanalization occur in the internal carotid or middle cerebral artery. However, few LVOs with a multivessel disease can be difficult to treat. This study aimed to determine the outcomes of mechanical thrombectomy in patients with both anterior and middle cerebral artery occlusions.Methods: We retrospectively collected data for patients who had undergone mechanical thrombectomy since January 2016 at Fukushima Medical University and its affiliated institutions (10 institutions). Patients with occluded vessels in the anterior and middle cerebral arteries were selected, and patient background, treatment course, and outcomes were reviewed.Results: A total of 341 mechanical thrombectomies were performed during the study period. Seven patients had occlusions involving both anterior and middle cerebral arteries. In these seven patients, the median time from onset to imaging, imaging to puncture, and puncture to recanalization was 106, 60, and 74 min, respectively. Only one patient (14%) had a modified Rankin Scale of 0–2 at 90 days.Conclusion: Comorbid anterior cerebral artery occlusion may worsen the outcome of patients with middle cerebral artery occlusion.

Le Fort I osteotomy is a common surgical technique for correcting jaw deformities. Although it is generally a safe procedure, there have been cases of postoperative vascular complications, which include arteriovenous fistulas. Published reports describe the development of arteriovenous fistulas that originate from the maxillary artery after this procedure; nevertheless, no cases of arteriovenous fistulas arising from the middle meningeal artery (MMA) have been reported. We present the case of a 19-year-old woman who developed pulsatile tinnitus immediately following a Le Fort I osteotomy. Angiography with proximal flow control of the external carotid artery showed an arteriovenous fistula between the extracranial portion of the MMA and the pterygoid venous plexus. The fistula was successfully treated using coil embolization, preserving the maxillary artery, which results in tinnitus resolution. In this report, the effectiveness of endovascular treatment for arteriovenous fistulas of the MMA that occur following a Le Fort I osteotomy was demonstrated. Angiography with proximal flow interruption was effective in shunt location detection.
