[Idiopathic hypertrophic pachymeningitis]. / Idiopaticheskii gipertroficheskii pakhimeningit.

The article presents a case of idiopathic hypertrophic pachymeningitis of a 61-year-old male patient with severe cephalgia and progressive neuropathy of the oculomotor nerves. The diagnosis was confirmed by MRI with gadolinium, which revealed thickening of the dura mater with accumulation of paramagnetic in the convexital parts of the frontal and temporal regions, as well as on the base of the skull and tentorium. During the use of pulse therapy with glucocorticosteroids (GCS) the symptoms regressed, but when the therapy was stopped, there was a relapse of ptosis and oculomotor abnormalities on the other side followed by a slower effect of GCS therapy. The article also presents a brief review of current knowledge about this pathology.

[Russian study on brain aneurysm surgery: a continuation (RIHA II)]. / Rossiiskoe issledovanie po khirurgii anevrizm golovnogo mozga: prodolzhenie (RIKhA II).

OBJECTIVE: To assess the main performance indicators of neurosurgical departments in surgical treatment of cerebral aneurysms in the Russian Federation. MATERIAL AND METHODS: We analyzed 22 neurosurgical departments (19 regional and 3 federal hospitals) in 2017 and 2021. The study enrolled 6.135 patients including 3.160 ones in 2017 and 2.975 ones in 2021. We studied the features of surgical treatment of cerebral aneurysms in different volume hospitals and factors influencing postoperative outcomes. RESULTS: The number of surgeries for cerebral aneurysms decreased from 2.950 in 2017 to 2.711 in 2021. Postoperative mortality rate was 6.3% and 5.6%, respectively. The number of microsurgical interventions decreased from 60% in 2017 to 48% in 2021. The share of endovascular interventions increased from 40% to 52%, respectively. Endovascular embolization was accompanied by stenting in 55% of cases. Simultaneous revascularization was carried out in 2% of cases. In 2021, the number of patients undergoing surgery in acute period of hemorrhage increased to 70% (in 2017 - 61%). The number of hospitals performing more than 50 surgical interventions for cerebral aneurysms annually increased from 14 in 2017 to 17 in 2021. CONCLUSION: Certain changes in neurosurgical service occurred in 2021 compared to 2017. Lower number of surgical interventions for cerebral aneurysms, most likely caused by the COVID-19 pandemic, is accompanied by lower postoperative mortality. Endovascular interventions and revascularization techniques became more common. The number of surgeries in acute period after aneurysm rupture and hospitals performing more than 50 surgical interventions for cerebral aneurysms annually increased.

[Ischemic stroke at a young age on the context of chronic myeloleukosis]. / Ishemicheskii insul't v molodom vozraste na fone khronicheskogo mieloleikoza.

The article describes the clinical search for diagnosis and treatment of a patient who developed a severe ischemic stroke at a young age, when specifying the cause of which chronic myeloleucosis was identified. The unavailability of patient compliance and non-compliance with the recommended examination at the outpatient stage led to the development of severe complications. It would seem that the diagnosis of chronic myeloid leukemia, which does not represent excessive complexity, with the development of an acute condition in a young patient, such as an ischemic stroke, results in a complex diagnostic search, complicated by developing comorbidities due to general decompensation of the body.

[Surgical treatment of cerebral aneurysms in the Russian Federation]. / Khirurgicheskoe lechenie tserebral'nykh anevrizm v Rossiiskoi Federatsii.

OBJECTIVE: The objective of this study was to evaluate the results of surgical treatment of cerebral aneurysms in the Russian Federation. MATERIAL AND METHODS: We analyzed performance indicators in neurosurgical departments of regional and federal health institutions of the Russian Federation for 2017. The results of surgical treatment of cerebral aneurysms (CAs) were analyzed in 19 regional vascular centers (RVCs) in several federal districts and in 3 federal centers (FCs) with the most dynamically developing vascular neurosurgery and smoothly running system of statistical data processing. RESULTS: The study included 3160 patients hospitalized to 22 medical institutions in 2017. Of these, 1808 patients were treated in RVCs, and 1352 patients were treated in FCs. We analyzed factors affecting the treatment outcome in CA patients. We identified features of CA treatment in clinics with a different amount of surgical intervention. CONCLUSION: An increase in the surgical activity in centers and simultaneous development of microsurgical and endovascular treatments for cerebral aneurysms reduce postoperative mortality. Due to the presence of a RVC network in the Russian Federation, many patients could receive necessary specialized treatment. The number of operations for cerebral aneurysms has increased 6-fold for the past 10 years.
