Cíl: Na základě výročního dotazníku byla provedena analýza použitých technik při endovaskulární rekanalizaci uzávěrů velkých mozkových tepen při léčbě akutních ischemických cévních mozkových příhod (iCMP) v roce 2021. Metodika: V roce 2022 byla dotazníkem oslovena všechna centra vysoce specializované i cerebrovaskulární péče a dvě iktová centra v České republice. Strukturovaný dotazník v části o endovaskulámfch výkonech pro iCMP se zaměřil na počet trombektomovaných pacientů, poměr výkonů, kdy byl technicky použit pouze stentretriever oproti kombinaci stentretrievera aspirační katétra počet výkonů, kdy byl použit pouze aspirační katétr. Dále byly dotázány počty akutně implantovaných stentů extra- a intrakraniálně v rámd těchto výkonů a procento použití balónkových pracovních katétrů. Výsledky: Mechanická trombektomie byla v roce 2021 provedena u 1439 pacientů: ve 13 komplexních cerebrovaskulámích centrech v rozsahu od 70 do 147 léčených pacientů a ve dvou iktových centrech pak bylo léčeno 41 a 49 pacientů. Vzájemný poměr použitých technik stentretriever: kombinace stentretriever + aspirační katétr: aspirační katétr byl zhruba 0,8 : 1 : 0,6. Celkem bylo akutně implantováno 147 extrakraniálních stentů (na centra v rozmezí 0 až 19) a 23 intrakraniálních stentů (na centra v rozmezí 0 až 6). Celkově byl akutně implantován stentů 11,8 % pacientů. Balónkové katétry byly použity v 55% výkonů. Závěr: V dotazovaných parametrech je patrné, že počet endovaskulámě léčených pacientů pro iCMP v České republice v roce 2021 mírně klesl (na 99,3 % roku 2020), počet výkonů v komplexních centrech se počtem lišil až dvojnásobně. Akutně byly implantovány stenty u 11,8 % výkonů a technika zástavy toku v přístupové tepně byla použita ve zhruba 55 % výkonů.
Aim: Based on an annual questionnaire, an analysis of the techniques used in endovascular recanalization of large cerebral artery occlusions in the treatment of acute ischemic stroke (AIS) in 2021 was performed. Method: In 2022, all centres of highly specialised cerebrovascular care and 2 primary centres in the Czech Republic were surveyed. The structured questionnaire in the section on endovascular procedures for AIS focused on the number of patients thrombectomized, the proportion of procedures where technically only a stent retriever was used versus a combination of stent retriever and aspiration catheter, and the number of procedures where only an aspiration catheter was used. The numbers of acutely implanted extra- and intracranial stents in these procedures and the percentage of balloon guiding catheters used were also queried. Results: Mechanical thrombectomy was performed in 1439 patients in 2021, of whom between 70 and 147 patients were treated in 13 comprehensive cerebrovascular centres, and 41 and 49 patients were treated in two ict centres. The ratio of stentretriever: stentretriever + aspiration catheter: aspiration catheter combination techniques used was approximately 0,8 : 1: 0, 6. A total of 114 extracranial stents (per centre ranging from 0-19) and 19 intracranial stents (per centre ranging from 0-6) were implanted acutely. Overall, a stent was acutely implanted in 11.8% of patients. Balloon catheters were used in 55% of the procedures. Conclusion: The surveyed parameters show that the number of patients treated endovascularly for iCMP in the Czech Republicin 2021 slightly decreased (to 99.3% in 2020), the number of procedures in complex centres differed by up to two times. The stent were acutely implanted in 11.8% procedures. The technique of flow arrestin the access artery was used in about 55% of procedures.

Cíl: Autoři podávají analýzu počtů endovaskulárních neurointervenčních výkonů na akreditovaných pracovištích v České Republice v letech 2013-2020. Metodika: V letech 2013-2020 byla obesílána dotazníkem všechna centra vysoce specializované cerebrovaskulární péče a dvě iktová centra v České republice. Strukturovaný dotazník se zaměřil na počty jednotlivých endovaskulárních intervenčních výkonů. Na základě zaslaných počtů tří nejčastěji prováděných výkonů (endovaskulární léčba akutních ischemických cévních mozkových příhod, stenóz mozkových tepen intrakraniálních i extrakraniálních a mozkových aneurysmat) byly vytvořeny osmileté vývoje počtu výkonů a dále pak úhrnných počtů všech endovaskulárních výkonů (léčby disekcí krkavic, mozkových a míšních arteriovenózních zkratů, tumorů báze lební, epistaxe a vazospazmů při subarachnoidálním krvácení). Výsledky: Mechanická trombektomie byla na vzestupu ze 417 výkonů v roce 2013 na 1468 v roce 2019. Do roku 2019 jsme zaznamenali meziroční nárůst těchto výkonů o 132 v roce 2017, o 154 v roce 2018, o 148 v roce 2019. V roce 2020 došlo k celkovému poklesu o 19 výkonů. U počtu pacientů léčených pro stenózy extra- a intrakraniálních tepen angioplastikou, případně se zavedením stentu, a u endovaskulárně léčených mozkových aneurysmat je trend stagnující. Závěr: Ve sledovaných podskupinách nemocných léčených endovaskulárně pro akutní ischemickou mozkovou příhodu, pro ateromatózní stenózu extra- a intrakraniálních tepen a aneurysmat mozkových tepen přetrvávají nadále významné rozdíly mezi akreditovanými centry. V roce 2020 došlo k poklesu počtu výkonů v důsledku epidemie SARS-CoV-2.
Aim: The authors analysed numbers of endovascular neurointerventional procedures in Czech Republic comprehensive neurovascular centres in the years from 2013 to 2020. Methods: The questionnaire was sent to all tertiary and two secondary neurovascular centres in Czech Republic. Numbers of each specified procedure were required. On basis of the 3 most frequently performed procedures (endovascular therapy of acute ischemic stroke, extra- and intracranial stenoses, and intracranial aneurysms) the eight-year trends of each procedure frequency, and total numbers of all neurovascular procedures (i.e. carotid dissections, intracranial stenoses, cerebral and spinal arteriovenous shunts, skull base tumors, epistaxis, vasospasms after subarachnoid hemorrhage) were evaluated. Results: Frequency of the mechanic thrombectomy increased from 417 procedures in the year 2013 to 1468 procedures in the year 2019. There was yearly increase of the number of procedures by 132 in 2017, by 154 in 2018, by 148 in 2019. In 2020 number of procedures for ischemic stroke decreased by 19. There was stagnation in numbers of carotid angioplasties, and treated cerebral aneurysms during the studied period. Conclusion: There were significant differences revealed among cerebrovascular centres regarding numbers of treated patiens for acute ischemic stroke, extra- and intracranial stenoses, and cerebral aneurysms. The number of neurovascular procedures decreased due to the SARS-CoV-2 pandemic in 2020.
Intradural spinal arteriovenous fistulas (sAVF) are spinal vascular lesions that usually manifest due to myelopathy or local symptoms caused by venous congestion and ischemia. In addition, perimedullary arteriovenous fistulas (PMAVF) in particular may rupture and cause subarachnoid or intramedullary hemorrhage along with relevant symptoms. Subarachnoid hemorrhage (SAH) can propagate into cranial space with clinically dominant symptoms and signs of typical aneurysmal intracranial SAH. The standard workup for cerebral SAH, after excluding an intracranial source of hemorrhage, is usually limited to a cervical spine MRI; therefore, thoracolumbar sources of hemorrhage can be missed, or their diagnosis may be delayed. Here we present a case of a pregnant patient who presented with cerebral SAH. The source of hemorrhage was not initially identified, leading to a presumptive diagnosis of benign pretruncal non-aneurysmal SAH. The correct diagnosis of spinal thoracolumbar PMAVF was revealed 2.5 months later due to the progression of local symptoms. While the diagnosis was being refined and endovascular treatment was being planned (but delayed due to pregnancy), there was a recurrence of intraconal hemorrhage followed by brainstem hemorrhage. This led to significant clinical deterioration. The PMAVF was then treated microsurgically and the patient experienced partial recovery.

BACKGROUND: There are presently no grading scales that specifically address the outcomes of cranial dural arteriovenous fistula (dAVF) after stereotactic radiosurgery (SRS). OBJECTIVE: To design a practical grading system that would predict outcomes after SRS for cranial dAVFs. METHODS: From the International Radiosurgery Research Foundation (University of Pittsburgh [41 patients], University of Pennsylvania [6 patients], University of Sherbrooke [2 patients], University of Manitoba [1 patient], West Virginia University [2 patients], University of Puerto Rico [1 patient], Beaumont Health System 1 [patient], Na Homolce Hospital [13 patients], the University of Virginia [48 patients], and Yale University [6 patients]) centers, 120 patients with dAVF treated with SRS were included in the study. The factors predicting favorable outcome (obliteration without post-SRS hemorrhage) after SRS were assessed using logistic regression analysis. These factors were pooled with the factors that were found to be predictive of obliteration from 7 studies with 736 patients after a systematic review of literature. These were entered into stepwise multiple regression and the best-fit model was identified. RESULTS: Based on the predictive model, 3 factors emerged to develop an SRS scoring system: cortical venous reflux (CVR), prior intracerebral hemorrhage (ICH), and noncavernous sinus location. Class I (score of 0-1 points) predicted the best favorable outcome of 80%. Class II patients (2 points score) had an intermediate favorable outcome of 57%, and class III (score 3 points) had the least favorable outcome at 37%. The ROC analysis showed better predictability to prevailing grading systems (AUC = 0.69; P = .04). Kaplan-Meier analysis showed statistically significant difference between the 3 subclasses of the proposed grading system for post-SRS dAVF obliteration (P = .001). CONCLUSION: The proposed dAVF grading system incorporates angiographic, anatomic, and clinical parameters and improves the prediction of the outcomes following SRS for dAVF as compared to the existing scoring systems.

BACKGROUND: Dural arteriovenous fistulas (DAVFs) can be categorized based on location. OBJECTIVE: To compare stereotactic radiosurgery (SRS) outcomes between cavernous sinus (CS) and non-CS DAVFs and to identify respective outcome predictors. METHODS: This is a retrospective study of DAVFs treated with SRS between 1988 and 2016 at 10 institutions. Patients' variables, DAVF characters, and SRS parameters were included for analyses. Favorable clinical outcome was defined as angiography-confirmed obliteration without radiological radiation-induced changes (RIC) or post-SRS hemorrhage. Other outcomes were DAVFs obliteration and adverse events (including RIC, symptomatic RIC, and post-SRS hemorrhage). RESULTS: The overall study cohort comprised 131 patients, including 20 patients with CS DAVFs (15%) and 111 patients with non-CS DAVFs (85%). Rates of favorable clinical outcome were comparable between the 2 groups (45% vs 37%, P = .824). Obliteration rate after SRS was higher in the CS DAVFs group, even adjusted for baseline difference (OR = 4.189, P = .044). Predictors of favorable clinical outcome included higher maximum dose (P = .014) for CS DAVFs. Symptomatic improvement was associated with obliteration in non-CS DAVFs (P = .005), but symptoms improved regardless of whether obliteration was confirmed in CS DAVFs. Non-CS DAVFs patients with adverse events after SRS were more likely to be male (P = .020), multiple arterial feeding fistulas (P = .018), and lower maximum dose (P = .041). CONCLUSION: After SRS, CS DAVFs are more likely to obliterate than non-CS ones. Because these 2 groups have different total predictors for clinical and radiologic outcomes after SRS, they should be considered as different entities.

OBJECTIVE: This study aims to evaluate the outcomes of Gamma Knife stereotactic radiosurgery (SRS) for dural arteriovenous fistulas (dAVFs) in older patients (≥65 years) compared with younger patients (age <65 years). METHODS: Two groups with a total of 96 patients were selected from a database of 133 patients with dAVF from 9 international medical centers with a minimum 6 months follow-up. A 1:2 propensity matching was performed by nearest-neighbor matching criteria based on sex, Borden grade, maximum radiation dose given, and location. The older cohort consisted of 32 patients and the younger cohort consisted of 64 patients. The mean overall follow-up in the combined cohort was 42.4 months (range, 6-210 months). RESULTS: In the older cohort, a transverse sinus location was found to significantly predict dAVF obliteration (P = 0.01). The post-SRS actuarial 3-year and 5-year obliteration rates were 47.7% and 78%, respectively. There were no cases of post-SRS hemorrhage. In the younger cohort, the cavernous sinus location was found to significantly predict obliteration (P = 0.005). The 3-year and 5-year actuarial obliteration rates were 56% and 70%, respectively. Five patients (7.8%) hemorrhaged after SRS. Margin dose ≥25 Gy was predictive of unfavorable outcome. The obliteration rate (P = 0.3), post-SRS hemorrhage rate (P = 0.16), and persistent symptoms after SRS (P = 0.83) were not statistically different between the 2 groups. CONCLUSIONS: SRS achieves obliteration in most older patients with dAVF, with an acceptable rate of complication. There was no increased risk of postradiosurgery complications in the older cohort compared with the younger patients.

OBJECTIVE: In this multicenter study, the authors reviewed the results obtained in patients who underwent Gamma Knife radiosurgery (GKRS) for dural arteriovenous fistulas (dAVFs) and determined predictors of outcome. METHODS: Data from a cohort of 114 patients who underwent GKRS for cerebral dAVFs were compiled from the International Gamma Knife Research Foundation. Favorable outcome was defined as dAVF obliteration and no posttreatment hemorrhage or permanent symptomatic radiation-induced complications. Patient and dAVF characteristics were assessed to determine predictors of outcome in a multivariate logistic regression analysis; dAVF-free obliteration was calculated in a competing-risk survival analysis; and Youden indices were used to determine optimal radiosurgical dose. RESULTS: A mean margin dose of 21.8 Gy was delivered. The mean follow-up duration was 4 years (range 0.5-18 years). The overall obliteration rate was 68.4%. The postradiosurgery actuarial rates of obliteration at 3, 5, 7, and 10 years were 41.3%, 61.1%, 70.1%, and 82.0%, respectively. Post-GRKS hemorrhage occurred in 4 patients (annual risk of 0.9%). Radiation-induced imaging changes occurred in 10.4% of patients; 5.2% were symptomatic, and 3.5% had permanent deficits. Favorable outcome was achieved in 63.2% of patients. Patients with middle fossa and tentorial dAVFs (OR 2.4, p = 0.048) and those receiving a margin dose greater than 23 Gy (OR 2.6, p = 0.030) were less likely to achieve a favorable outcome. Commonly used grading scales (e.g., Borden and Cognard) were not predictive of outcome. Female sex (OR 1.7, p = 0.03), absent venous ectasia (OR 3.4, p < 0.001), and cavernous carotid location (OR 2.1, p = 0.019) were predictors of GKRS-induced dAVF obliteration. CONCLUSIONS: GKRS for cerebral dAVFs achieved obliteration and avoided permanent complications in the majority of patients. Those with cavernous carotid location and no venous ectasia were more likely to have fistula obliteration following radiosurgery. Commonly used grading scales were not reliable predictors of outcome following radiosurgery.
