Objective – to improve the treatment quality for patients with spinal arteriovenous malformations (AVM).Materials and methods. A retrospective analysis of endovascular and surgical treatment of patients was made. In SO «Scientific-practical Center of endovascular neuroradiology NAMS of Ukraine» since 2005 till 2018 were operated 55 patients (34 (61.8 %) men and 21 (38.2 %) women). The age of patients ranged from 11 to 62 years (middle age is 45.3 years). The classification proposed by Anson and Spetzler in 1992 was used in order to divide patients into experimental groups: type I, arteriovenous fistula (AVF); type II, glomus intramedullary AVM; type III, juvenile AVM; and type IV, perimedullary AVF. Patients with type I were 36 (65.5 %), with ІІ type – 10 (18.2 %), with ІIІ type – 5 (9.0 %), with IV type – 4 (7.3 %). For diagnostics were used MRI and spinal angiography. The Aminoff–Logue scale was used for assessment of the neurological deficiency severity. Early postoperative complications (CSF) leakage, wound infection, early postoperative worsening) were counted.Results. 12 (21.8 %) patients were treated using the microsurgical method and 43 (78.2 %) were treated endovascular. We used endovascular and microsurgical methods to treat patients with I type spinal AVM. Microsurgical intervention for 9 (33 %) patients was performed. Complete disconnection of fistula was achieved in 9 patients. Early postoperative complication (CSF leakage) was observed in 1 (11 %) case. Endovascular treatment was performed for 27 (67 %) patients. Total disconnection was achieved in 16 (59 %) cases, 17 patients (63 %) had early transient neurological worsening. Embolization is the first-line treatment for patients with type II AVM – 8 (80 %) patients. Complete obliteration of AVM was attained in 5 patients (62.5 %), 6 (75 %) patients suffered from early worsening of postoperative neurological symptoms. The microsurgical method was used in case of low risk of spinal cord injury in 2 patients (20 %), AVMs were excluded totally in 2 patients and in 1 patient neurological deterioration was stabilized. All patients with III type AVM were treated endovascular. AVM was obliterated complete in 1 patient (20 %). Three (60 %) patients had transient neurological deterioration. Endovascular method was used to treat 3 (75 %) patients with type IV AVM. Totally disconnection of AVM was achieved in 1 (33 %) patient. Super-selective catheterization of all conductive arteries was not possible. Neurological worsening was observed in 1 (33 %) patient.Conclusions. Angiography is the first-line diagnostic method which permits to find the most effective and safe way (endovascular or/and microsurgical treatment) to disconnect AVM from spinal cord bloodstream. Microsurgical intervention helps to achieve eye-controlled total arteriovenous disconnection. Microsurgical technique usage leads to good neurological results – neurological improvement the following day after surgery in all cases of AVM type I treatment. The structure of AVM determines effectiveness, radicality, method of treatment and the level of feeder artery catheterization. The main goal of embolization to achieve the safe catheterization level of the afferent. Multimodal treatment, which includes endovascular and microsurgical methods, is the most effective in case of AVM II and III types.

The aim: To obtain the first estimates the incidence of surgical site infection in patients undergoing neurosurgical procedures and antimicrobial resistance of responsible pathogens, and determine their impact on inpatient mortality in Ukraine. Materials and methods: We performed a multicenter prospective study was patient-based data of SSIs were according to CDC/NHSN methodology. This study included patients undergoing a neurosurgical procedure in 11 tertiary care hospitals from different regions of Ukraine from January 1st, 2018 to December 31st, 2020. Results: A total of 1697 neurosurgical procedures associated with a 90-day SSI were identified (19.4% of 8741 procedures). Of these, 69.5% SSI were identified after craniotomy and 30.5% after ventricular shunt. The Meningitis or ventriculitis (20.9%) were found to be the most common underlying condition among these patients followed by Intracranial infection (18.7%), and Osteomyelitis (14.6%) congenital malformation. Over a 90-day surveillance period, 387 died (4.4%). Fifty seven percent of deaths in SSI patients were attributable to infection. Meningitis or ventriculitis and Intracranial infection were associated with a higher mortality. Craniotomy was associated with a higher mortality more frequently than did Ventricular shunt. Escherichia coli were most commonly reported, accounting for 26.3% of all organisms, followed by Staphylococcus aureus, Enterobacter spp., Pseudomonas aeruginosa, Enterococcus spp., and Klebsiella pneumoniae. Meticillin resistance was found in 33.7% of S. aureus isolates, and vancomycin resistance was found in 12.7% of enterococci. Conclusions: The incidence of SSI and mortality after neurosurgical procedures in Ukraine is high. This is due to increase emergence of antimicrobial-resistant pathogens and risk factors in neurosurgery patients.

Today in Ukraine there is no single standardized protocol for the treatment of patients in the acute period of ischemic stroke using modern methods of diagnosis and treatment, which include thrombolytic therapy and endovascular treatment. This protocol was created and implemented in Scientific-practical Center of endovascular neuroradiology, NAMS of Ukraine and is based on the latest recommendations of AHA/ASA and ESO, as well as registers of patients with ischemic stroke. The main purpose of this publication is the creation and implementation of «instructions» for the diagnosis and selection of objective tactics for treating patients in the acute period of ischemic stroke.

Однією із найпоширеніших причин смертності населення є інсульти, котрі в більшості країн посідають третє місце серед причин смертності. Поширеність інсультів в Україні одна з найбільших в Європі-282,3 випадку на 100 тис. населення, або близько 100 тис. щорічно. Проаналізовані дані МОЗ України, низки лікувальних установ України та м.

AbstractIntracranial pial arteriovenous fistula (PAVF) is a rare cerebrovascular pathology characterized by abnormal direct high-flow connection between the pial or cortical feeding artery and draining vein. Dural arteriovenous fistula (DAVF) is a pathological shunt between the meningeal arteries and dural sinuses or meningeal veins. In case of association between PAVF and DAVF, diagnosis and treatment are more challenging. The high-flow arteriovenous shunt and deep venous drainage make PAVF more preferable for endovascular treatment; however, their embolization during single-session procedures can lead to extensive thrombosis of the draining veins and unfavorable outcomes. We present a case report of endovascular embolization of an intracranial PAVF–DAVF in a 2.5-year-old child. At the time of admission, the patient had hydrocephalus, mental retardation, pyramidal insufficiency, and seizures. Occlusion of the fistula was performed during two stages of embolization to reduce the risk of severe venous stasis and venous thrombosis. Guglielmi detachable coils (GDCs) and a liquid embolic agent (Histoacryl with Lipiodol) were used for embolization. The patient recovered well after the procedure, with significant mental improvement. This suggests that the deployment of GDCs in the afferent artery near a fistula before embolization with a liquid embolic agent can minimize the risk of uncontrolled penetration of the embolization into the draining veins and dural sinus. A multisession procedure can be an effective and reasonable method of PAVF and DAVF occlusion among existing treatment options.
