The study objective is to analyze surgical outcomes in patients with hemorrhagic stroke treated by endoscopic aspiration in five regional vascular centers in Russia and to evaluate capabilities and benefits of this surgical procedure. Material and methods. The study included 296 patients with hemorrhagic stroke (with various locations of the hemorrhage) that underwent endoscopic aspiration between 2006 and 2018 at one of the following institutions: N.V. Sklifosovsky Research Institute for Emergency Medicine (Moscow), City Clinical Emergency Hospital No. 1 (Omsk), Regional Clinical Hospital (Yaroslavl), N.A. Semashko Republic Clinical Hospital (Simferopol), Irkutsk Regional Clinical Hospital. Neurosurgery departments of these healthcare institutions are the parts of regional vascular centers. We used Glasgow Outcome Scale to evaluate outcomes of surgical treatment. Results. Complete recovery was observed in 52 (17.5 %) patients, while 52 (17.5 %) patients developed moderate disability and 131 patients (44.5 %) developed severe disability. Four (1.5 %) patients developed a vegetative state. Fifty-seven (19 %) patients died after surgery. Conclusion. The experience of treating hemorrhagic stroke in five neurosurgical centers demonstrates that endoscopic aspiration of hypertensive intracerebral hemorrhages is in no way inferior to microsurgery. It ensures satisfactory results and can be used in patients with various hemorrhages.

Atlas dislocation after transverse ligament injury is one of the most rare types of trauma to the upper cervical level. If magnetic resonance imaging of the craniovertebral junction reveals the Kassam line passing through the cervix of the odontoid process, a transnasal approach can be used for surgical treatment. Here, we present a case in which an endoscopic endonasal approach was used to treat chronic traumatic transligamentous atlas dislocation. A 26-year-old male underwent two-stage surgical treatment; during the first stage, posterior decompression and fixation were performed under halo immobilization. In the second stage, a transnasal endoscopic approach to the odontoid process was used. A transnasal approach permitted complete decompression of the medulla oblongata and facilitated early extubation of the patient without any postoperative complications such as respiratory or pharyngopalatine deficiency. The patient was discharged in good condition 9 days after the surgery.
