Aim. To evaluate short- and long‑term angiographic and clinical outcomes of endovascular treatment of patients with distal aneurysms of cerebellar arteries.Materials and methods. The outcomes of endovascular treatment of 6 patients with distal aneurysms of cerebellar arteries who underwent surgery at the Neurosurgical Division No. 3 of the Polenov Russian Research Institute of Neurosurgery between January 1 of 2017 and March 31 of 2023 were analyzed.Results. The following endovascular methods were used: occlusion of the aneurysm sac using only detachable coils (n = 2); occlusion using stent‑assisted coiling (n = 3); deconstructive intervention with occlusion of the main artery (n = 1). In 1 of 2 cases of coil‑only aneurysm occlusion, additional stent‑assisted occlusion was performed due to recurrence. Among 6 aneurysms, 1 (16.65 %) aneurysm was radically excluded from the blood flow (class А); 4 (66.7 %) were excluded subtotally (class B); 1 (16.65 %) was excluded partially (class С). Control angiography at least 6 months after showed radical exclusion of the aneurysm from the blood flow (class A) in 5 (83.3 %) patients, subtotal exclusion (class В) in 1 (16.7 %) patient. Clinical outcome was excellent in 5 (83.3 %) patients (0 points per the modified Rankin scale); in 1 patient after deconstructive surgery, augmentation of neurological symptoms with following partial regression was observed (2 points per the modified Rankin scale). Complications during deconstructive surgery were observed in 1 (16.7 %) patient.Conclusion. Deconstructive surgery of the distal aneurysms of cerebellar arteries can be associated with high risk of postoperative ischemic complications with development of persisting neurological deficit. Surgical interventions with preservation of the artery lumen (including reconstructive surgeries) should be the method of choice in endovascular treatment of distal aneurysms of cerebellar arteries due to minimal risk of ischemic complications and improved clinical outcomes of surgical treatment.

Posterior inferior cerebellar artery (PICA) infarction can lead to ischemic stroke at the lateral part of the medullary oblongata. PICA dissection can also elicit an ischemic event in this region but its detection on radiological images is difficult due to the small diameter of the vessel. We report a 48-year-old male with Wallenberg syndrome due to PICA dissection, which was difficult to diagnose on first admission. He reported sudden-onset sensory disturbance on the right side of his face, ataxic gait, and headache.Brain magnetic resonance imaging (MRI) revealed a fresh cerebral infarct in the right lateral medulla oblongata. Serial MRI and magnetic resonance angiography (MRA) performed at the time of his admission failed to demonstrate cerebral vessel abnormalities. MRI study performed 18 months after the attack revealed a fusiform aneurysm on the lateral medullary segment of the PICA; its site was extremely close to the cerebral infarct. We concluded that the infarct was due to PICA dissection because it was sudden onset of the symptom at the event and the lesion enlarged dissecting aneurysm located to be coincident with symptoms of Wallenberg syndrome. The aneurysm was trapped, and an occipital artery-PICA bypass was placed. At the latest follow-up, one year after the operation, he manifested no neurological symptoms.Imaging findings at the time of his first admission indicated that the PICA was
