Carotid endarterectomy (CEA) after an unstable neurological presentation is still a controversial issue. The aim of this study was to evaluate outcomes of urgent (≤48 hr) CEA in patients with crescendo transient ischemic attack (cTIA) or stroke in evolution (SIE).A retrospective analysis was performed using prospectively collected data from all consecutive neurologically unstable patients who underwent urgent CEA during the period from January 2013 to November 2018. End points were 30-day any stroke and death rate, symptomatic intracerebral hemorrhage (ICH), myocardial infarction (MI), surgical site bleeding requiring intervention, National Institutes of Health Stroke Scale (NIHSS) score variation, and functional outcome at 90 days assessed by the modified Rankin scale (mRS). Patients were evaluated according to clinical presentation (cTIA or SIE).A total of 46 neurologically unstable patients with cTIA (20 patients; 43.5%) and SIE (26 patients; 56.5%) were included. The 30-day risk of any stroke or death was 10.0% (2 of 20) in the cTIA group and 7.7% (2 of 26) in the SIE group. No symptomatic ICH or MI was detected after surgery in either study group. A total of 2 patients (4.3%; 1 cTIA, 1 SIE) underwent reoperation for surgical site bleeding. In patients with SIE, the mean NIHSS score on admission was 9.85 ± 5.12. Postoperatively, 22 (84.6%) of the 26 patients with SIE had clinical improvement of their neurological deficit, 3 (11.5%) patients had no change, and 1 (3.8%) patient died. On discharge, the mean NIHSS score was 4.31 ± 6.09 points and was significantly improved compared with NIHSS scores at admission (P0.001). At 3 months, 21 patients (80.8%) with SIE had a good clinical outcome (mRS ≤ 2).Urgent CEA in neurologically unstable patients can be performed with acceptable perioperative risks. Moreover, in well-selected patients with SIE, urgent CEA may be associated with significantly improved final functional outcomes.

Real-world data report worse 3-month clinical outcomes in elderly patients with acute ischemic stroke (AIS) treated with mechanical thrombectomy (MT). The aim was to identify factors influencing clinical outcome in elderly patients with anterior circulation AIS treated with MT (±intravenous thrombolysis (IVT)). In a retrospective, monocentric study, analysis of prospectively collected data of 138 patients (≥80 years) was performed. IVT was an independent negative predictor (OR 0.356, 95% CI: 0.134–0.942) and female sex an independent positive predictor (OR 4.179, 95% CI: 1.300–13.438) of 3-month good clinical outcome (modified Rankin scale 0–2). Female sex was also an independent negative predictor of 3-month mortality (OR 0.244, 95% CI: 0.100–0.599). Other independent negative predictors of 3-month good clinical outcome were older age, lower pre-stroke self-sufficiency, more severe neurological deficit and longer procedural intervals. Mortality was also independently predicted by longer procedural interval and by the occurrence of symptomatic intracerebral hemorrhage (p &lt, 0.05 in all cases). Our results demonstrated, that in patients aged ≥80 years with anterior circulation AIS undergoing MT (±IVT), IVT reduced the chance of 3-month good clinical outcome and female sex was associated with a greater likelihood of 3-month good clinical outcome and lower probability of 3-month mortality.

We aimed was to assess the factors influencing therapy choice and clinical outcome after 3–4 months in patients with cerebral venous sinus thrombosis (CVST). In a retrospective, bi-centric study, the set consisted of 82 consecutive CVST patients (61 females; mean age 33.5 ± 15.7 years). Following data were collected: baseline characteristics, presence of gender-specific risk factors (GSRF), location and extent of venous sinus impairment, clinical presentation, type of treatment, recanalization, presence of parenchymal lesions, and clinical outcome after 3–4 months (assessed using the modified Rankin Scale [mRS], with excellent outcome defined as mRS 0–1). Multivariate logistic regression analysis was used for statistical evaluation. After 3–4 months, complete recovery was achieved in 41 (50%) and excellent clinical outcome in 67 (81.7%) patients. Female sex (OR 0.11; p = 0.0189) and presence of focal neurologic deficit (OR 0.16; p = 0.0165) were identified as significant independent negative predictors and, the presence of GSRF (OR 15.63; p = 0.0011) as significant independent positive predictor of excellent clinical outcome. In conclusion, in our CVST patients, the presence of GSRF was associated with excellent clinical outcome, while the female sex itself was associated with poorer clinical outcome.

Background and Purpose— We aimed to determine the safety and mortality after mechanical thrombectomy in patients taking vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs). Methods— In a multicenter observational cohort study, we used multiple logistic regression analysis to evaluate associations of symptomatic intracranial hemorrhage (sICH) with VKA or DOAC prescription before thrombectomy as compared with no anticoagulation. The primary outcomes were the rate of sICH and all-cause mortality at 90 days, incorporating sensitivity analysis regarding confirmed therapeutic anticoagulation. Additionally, we performed a systematic review and meta-analysis of literature on this topic. Results— Altogether, 1932 patients were included (VKA, n=222; DOAC, n=98; no anticoagulation, n=1612); median age, 74 years (interquartile range, 62–82); 49.6% women. VKA prescription was associated with increased odds for sICH and mortality (adjusted odds ratio [aOR], 2.55 [95% CI, 1.35–4.84] and 1.64 [95% CI, 1.09–2.47]) as compared with the control group, whereas no association with DOAC intake was observed (aOR, 0.98 [95% CI, 0.29–3.35] and 1.35 [95% CI, 0.72–2.53]). Sensitivity analyses considering only patients within the confirmed therapeutic anticoagulation range did not alter the findings. A study-level meta-analysis incorporating data from 7462 patients (855 VKAs, 318 DOACs, and 6289 controls) from 15 observational cohorts corroborated these observations, yielding an increased rate of sICH in VKA patients (aOR, 1.62 [95% CI, 1.22–2.17]) but not in DOAC patients (aOR, 1.03 [95% CI, 0.60–1.80]). Conclusions— Patients taking VKA have an increased risk of sICH and mortality after mechanical thrombectomy. The lower risk of sICH associated with DOAC may also be noticeable in the acute setting. Improved selection might be advisable in VKA-treated patients. Registration— URL: https://www.clinicaltrials.gov . Unique identifier: NCT03496064.

Background The composition of intra-arterial clots might influence the efficacy of mechanical thrombectomy (MT) in ischemic stroke (IS) due to the acute occlusions within large cerebral arteries. The aims were to assess the factors associated with blood clot structure and the impact of thromboembolus structure on MT using stent-retrievers in patients with acute large artery IS in the anterior circulation.Methods and Results:In an observational cohort study, we studied the components of intra-arterial clots retrieved from large cerebral arteries in 80 patients with acute IS treated with MT with or without i.v. thrombolysis (IVT). Histology of the clots was carried out without knowledge of the clinical findings, including the treatment methods. The components of the clots, their age, origin and semi-quantitative graded changes in the architecture of the fibrin components (e.g., "thinning") were compared via neuro-interventional, clinical and laboratory data. The most prominent changes in the architecture of the fibrin components in the thromboemboli were associated with IVT (applied in 44 patients; OR, 3.50; 95% CI: 1.21-10.10, P=0.02) and platelet count (OR, 2.94; 95% CI: 1.06-8.12, P=0.04). Conclusions In patients with large artery IS treated with the MT using stent-retrievers, bridging therapy with IVT preceding MT and higher platelet count were associated with significant changes of the histological structure of blood clots.

Background: Endovascular therapy (EVT) with stent retrievers has been shown to be superior and safe (in the anterior circulation) in comparison with intravenous thrombolysis (IVT) alone or no specific therapy. We compared clinical outcome between patients undergoing EVT admitted directly to comprehensive stroke centers (CSCs) and patients transferred from primary stroke centers (PSCs) to a CSC. Materials and methods: Demographics, risk factors, and medical history of all consecutive EVT-treated stroke patients in collaborating stroke centers were collected. Patients were divided into three groups: treatment with IVT in a PSC before transfer to a CSC for EVT; treatment with IVT directly in a CSC with subsequent EVT in the same center; no treatment with IVT before EVT. Neurological status using the National Institutes of Health Stroke Scale (NIHSS) on admission and at day and self-sufficiency using the modified Rankin Scale (mRS) at day-90 were assessed. “Favorable clinical outcome” was defined as a mRS score of 0–2. Control computed tomography (CT) or magnetic resonance imaging (MRI) was done to determine symptomatic intracerebral hemorrhage (SICH). Results: A total of 568 patients (313 males; mean age, 66.1±13.2 years) were registered from January 2006 to the end of July 2015. Patients in all three groups did not differ in baseline characteristics except for the time to the start of EVT. The average delay of EVT start in patients transferred from PSC to CSC was 45 min. Subgroups did not differ significantly in SICH prevalence (overall prevalence 5.5%) and favorable clinical outcome (overall 46.7%). Conclusion: The benefit of direct transfer to a CSC merits further investigation. The present study showed both ways of stroke patients transport organization in the Czech Republic are comparably efficient and safe.

Background The timing of carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) is still a controversial issue. The aim of this study was to assess the safety of early carotid interventions in patients treated with thrombolysis for acute ischemic stroke. Methods A retrospective analysis was performed using prospectively collected data from consecutive patients who underwent CEA for symptomatic internal carotid artery stenosis within 14 days after the index neurological event during the period from January 2013 to July 2016. Patients who had undergone IVT before CEA were identified. The primary outcome measures were any stroke and death rate at 30 days, symptomatic intracerebral hemorrhage and surgical site bleeding requiring intervention. Results A total of 93 patients were included for the final analysis. Among these, 13 (14.0%) patients had undergone IVT before CEA while 80 (86.0%) patients had CEA only. The median time interval between IVT and CEA was 2 days (range: 0–13). A subgroup of 6 patients underwent CEA within 24 hours of administration of IVT. The 30-day combined stroke and death rate was 7.7% (1 of 13) among patients undergoing IVT before CEA and 5.0% (4 of 80) among those undergoing CEA only (P = 0.690). In the IVT group, there were no cerebral hemorrhages or significant surgical site bleeding events requiring reintervention. Conclusions Our experience indicates that CEA performed early after IVT for acute ischemic stroke, aiming not only to reduce the risk of stroke recurrence but also to achieve neurological improvement by reperfusion of the ischemic penumbra, may be safe and can lead to favorable outcomes.

Background: Strokes secondary to acute internal carotid artery (ICA) occlusion are associated with an extremely poor prognosis. The best treatment approach in this setting is still unknown. The aim of our study was to evaluate the efficacy, safety, and outcomes of emergent surgical revascularization of acute extracranial ICA occlusion in patients with minor to severe ischemic stroke. Methods: A retrospective analysis was performed using prospectively collected data of consecutive patients who underwent carotid thromboendarterectomy for symptomatic acute ICA occlusion during the period from January 2013 to December 2015. Primary outcomes were disability at 90 days assessed by the modified Rankin Scale (mRS) and neurological deficit at discharge assessed using the National Institute of Health Stroke Scale (NIHSS). Secondary outcomes were the recanalization rate, 30-day overall mortality, and any intracerebral bleeding. Results: During the study period, a total of 6 patients (5 men and 1 woman) with a median age of 64 years (range: 58-84 years) underwent emergent reconstruction for acute symptomatic ICA occlusion within a median of 5.4 hours (range: 2.9-12.0 hours) after symptoms onset. The median presenting NIHSS score was 10.5 points (range: 4-21). Before surgery, 4 patients (66.7%) had been treated by systemic recombinant tissue plasminogen activator lysis. The median time interval between initiation of intravenous thrombolysis and carotid thromboendarterectomy was 117.5 minutes (range: 65-140 minutes). Patency of the ICA was achieved in all patients. On discharge, the median NIHSS score was 2 points (range: 0-11 points). There was no postoperative intracerebral hemorrhage and zero 30-day mortality rate. At 3 months, 5 patients (83.3%) had a good clinical outcome (mRS ≤ 2). Conclusion: Patients presenting with minor to severe ischemic stroke syndromes due to isolated extracranial ICA occlusion may benefit from emergent carotid revascularization. Thorough preoperative neuroimaging is essential to aid in selecting eligible candidates for acute surgical intervention.

Anterior circulation stroke (ACS) is associated with typical symptoms, while posterior circulation stroke (PCS) may cause a wide spectrum of less specific symptoms. We aim to assess the correlation between the initial presentation of acute ischemic stroke (AIS) symptoms and the treatment timeline. Using a retrospective, observational, single-center study, the set consists of 809 AIS patients treated with intravenous thrombolysis (IVT) and/or endovascular treatment (EVT). We investigate the impact of baseline clinical AIS symptoms and the affected vascular territory on recanalization times in patients treated with IVT only and EVT (±IVT). Regarding the IVT-only group, increasing the National Institutes of Health Stroke Scale (NIHSS) score on admission and speech difficulties are associated with shorter (by 1.59 ± 0.76 min per every one-point increase, p = 0.036, and by 24.56 ± 8.42 min, p = 0.004, respectively) and nausea/vomiting with longer (by 43.72 ± 13.13 min, p = 0.001) onset-to-needle times, and vertigo with longer (by 8.58 ± 3.84 min, p = 0.026) door-to-needle times (DNT). Regarding the EVT (±IVT) group, coma is associated with longer (by 22.68 ± 6.05 min, p = 0.0002) DNT, anterior circulation stroke with shorter (by 47.32 ± 16.89 min, p = 0.005) onset-to-groin time, and drooping of the mouth corner with shorter (by 20.79 ± 6.02 min, p = 0.0006) door-to-groin time. Our results demonstrate that treatment is initiated later in strokes with less specific symptoms than in strokes with typical symptoms.

The benefit of mechanical thrombectomy over intravenous thrombolysis was definitively proved by several studies in 2015. It is relevant for proximal, large artery occlusions in the anterior circulation with onset of clinical symptoms lasting 6 hours. Two trials published in 2018 showed that in patients who are selected using CT perfusion or MR diffusion weighted imaging, thrombectomy significantly improves outcome even up to 24 hours from onset. The benefit of the vertebrobasilar circulation, where occlusion of large arteries occurs in 7 % cases, has not been proved by randomised studies yet. However, mechanical thrombectomy is performed in this arterial territory because of very poor prognosis of nonrecanalized occlusions there. Patients with acute ischemic stroke should be transferred to comprehensive stroke centres. These centres should provide parenchymal CT imaging and CT arteriography. These two modalities provide sufficient information to determine eligibility for endovascular treatment in the first 6 hours from stroke onset. Physicians performing endovascular therapy of stroke must be properly trained in clinical neuroscience, neuroimaging and neurointerventions. Success rate of this therapy depends on its organization which includes fast transport of patients, fast clinical and diagnostic evaluation, fast decisions, and availability of trained interventional team.

The results of treatment for spinal dural arteriovenous fistula (SDAVF) have been controversial. The goal of this study was to compare results of endovascular and surgical treatments to contribute to determining an optimal treatment strategy.A retrospective analysis of the set of 24 SDAVF patients (11 in the endovascular and 13 in the surgical group) was performed. The clinical effect (using the modified Rankin scale [mRS]), the radicality, and the number of clinical recurrences as well as the impact of age, the level of impairment, and the duration of symptoms before the treatment were evaluated.The average age was 60.1 ± 8.4 years. The median duration of symptoms before establishing a diagnosis was 12 (1-70) months. Clinical improvement was reported in 11 out of 24 (45.8%) patients (36.4% following embolization and 53.8% following surgery, p = 0.444). Radical performance was achieved in 47.4% of endovascular versus 92.9% of surgical procedures (p = 0.009). Clinical recurrence was reported in 35.3% of patients in the endovascular group, whereas no clinical recurrence was reported in the surgical group (p = 0.0133). The graphical residuum after 1 surgery out of 14 (7.1%) was cured early during the control angiography. Clinical improvement was reported 42.1% of patients with mRS ≤ 3 versus 60% of patients with mRS ≥ 4 and, in 57.1% of patients aged ≥ 60 versus in 30% of patients 60 years (p 0.05 in both cases). The impact of the duration of symptoms on the clinical results was not statistically significant.The surgical treatment of SDAVF appeared to be a more efficient method in terms of the clinical effect, radicality, and lower recurrence rate in comparison with the endovascular treatment. No statistically significant dependence of the clinical result on age, deficit burden, or symptom duration was found.

AIM To assess the safety and efficacy of mechanical thrombectomy (MT) with stent-retrievers in anterior circulation stroke (ACS) patients due to the occlusion of major cerebral arteries, and to compare the results achieved in patients on oral anticoagulation (OAC) and those not on OAC. MATERIALS AND METHODS The present retrospective study comprised 285 consecutive patients (115 males; mean age 74±13 years). The following data were collected: baseline characteristics, occurrence of risk factors, pre-event treatment with OAC, neurological deficit at the time of treatment, time to therapy, recanalisation rate (successful recanalisation defined as Thrombolysis in Cerebral Infarction score ≥2b), post-treatment imaging findings. The 90-day clinical outcome was assessed using modified Rankin scale (good outcome defined as 0–2). RESULTS The following statistically insignificant differences were found in 26 patients on OAC versus 259 patients without OAC: occurrence of symptomatic intracerebral haemorrhage 7.7% versus 8.1%, achievement of successful recanalisation 69.2% versus 82.6%, good 90-day clinical outcome 34.6% versus 56.8%, 90-day mortality 26.9% versus 20.8% (p>0.05 in all cases). Age and neurological deficit at the time of treatment were identified as independent negative predictors of good 90-day clinical outcome (odds ratio [OR]=0.90, 95% confidence interval [CI]: 0.88–0.94 and OR=0.83, 95% CI: 0.77–0.90, respectively) and as independent positive predictors of mortality (OR=1.12, 95% CI: 1.06–1.18 and, OR=1.17, 95% CI: 1.07–1.27, respectively; p CONCLUSIONS MT with stent-retrievers is safe and effective in ACS patients on OAC.

The goal of this study is to evaluate therapeutic trends for several diseases that represent risk factors for stroke. The relative frequency of therapy with compounds that influence the risk factors for stroke was monitored in a group of 3,290 patients who were hospitalised in the Stroke Unit at the University Hospital in Hradec Kralove between 2005 and 2012. For most drugs monitored, the reasons for the significant decrease or increase in use were causes other than the reduction of stroke risk. Despite this finding, the majority of statistically significant changes had, according to review of comparative studies, a posi- tive effect on prevention of stroke. Motivation to change treatment of stroke risk factors, such as hypertension, diabetes mellitus and hypercholesterolemia, was mainly aimed at sufficient disease management with a minimum of adverse effects. On the other hand, optimization of stroke recurrence and economic factors were motivations to treatment changes in prevention with antiplatelets. Antidiabetics were associated with an increase in met- formin use and reduction in insulin use. For antihyperten- sives, the most significant reduction was associated with the use of diuretics, although calcium channel blockers and beta-blockers are also less used. Additionally, the use of the ACE inhibitor ramipril increased

Aim To evaluate the safety and efficacy of multimodal endovascular treatment (EVT) of acute basilar artery occlusion (BAO), including bridging therapy [intravenous thrombolysis (IVT) with subsequent EVT], to compare particular EVT techniques and identify predictors of clinical outcome. Materials and methods This retrospective, multi-centre study comprised 72 acute ischaemic stroke patients (51 males; mean age 59.1 ± 13.3 years) with radiologically confirmed BAO. The following data were collected: baseline characteristics, risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, localization of occlusion, time to therapy, recanalization rate, post-treatment imaging findings. Thirty- and 90-day outcomes were evaluated using the modified Rankin scale with a good clinical outcome defined as 0–3 points. Results Successful recanalization was achieved in 94.4% patients. Stepwise binary logistic regression analysis identified the presence of arterial hypertension (OR = 0.073 and OR = 0.067, respectively), National Institutes of Health Stroke Scale (NIHSS) at the time of treatment (OR = 0,829 and OR = 0.864, respectively), and time to treatment (OR = 0.556 and OR = 0.502, respectively) as significant independent predictors of 30- and 90-day clinical outcomes. Conclusion Data from this multicentre study showed that multimodal EVT was an effective recanalization method in acute BAO. Bridging therapy shortens the time to treatment, which was identified as the only modifiable outcome predictor.

Introduction: The issue of resistance to antiplatelet therapy has raised many questions in the area of neurovascular diseases. The first objective of this work was to determine the prevalence of aspirin resistance in neurovascular patients with clinical non-responsiveness to aspirin treatment and a high-risk of atherothrombotic complications using two interpretable and independent methods (aggregation and PFA 100). The second objective was to find the correlation between both assays and to evaluate the results in groups at risk for various cerebrovascular diseases. Material and methods: Laboratory tests of aspirin resistance were performed in 79 patients with clinical non-responsiveness to aspirin treatment suffering from neurovascular diseases. Patients were divided into the two groups: expected low risk for aspirin resistance due to the first manifestation of a neurovascular disease (n = 34) and expected high risk due to the second clinical manifestation of a neurovascular disease (n = 45). Results: The prevalence of aspirin resistance in both groups combined as determined by the PFA-100 and CPG techniques were 50.6% and 17.7%, respectively. No correlation was found between the two techniques. Conclusions: No significant prevalence of aspirin resistance was demonstrated by either method despite the heterogeneous pathophysiological mechanisms. However, we are presently unable to provide an accurate opinion on the value of laboratory test result or routine monitoring in clinical neurology.

The frequency of patients diagnosed with cerebral venous sinus thrombosis (CVST) has increased due to the expanded use of noninvasive brain imaging methods. The aim of this study was to assess the correlations between the location and extent of venous sinus impairment, clinical presentation during the acute phase, recanalization, the presence of parenchymal lesions, and clinical outcome after 3 to 4 months in patients with CVST. In a retrospective study, clinical and magnetic resonance imaging data from a cohort of 51 consecutive patients with CVST (mean age 33.1 ± 15.4 years) were collected and analyzed. Good clinical outcome after 3 to 4 months, which was assessed using the modified Rankin scale, significantly negatively correlated with a thrombosis location in the left transverse, left sigmoid, or superior sagittal sinus ( P = .022, P = .045, and P = .046, respectively) and positively correlated with recanalization ( P = .048). The clinical outcome was significantly more favorable in the females with gender-specific risk factors than in the males ( P = .029). In conclusion, successful recanalization substantially helps to achieve good clinical outcome in patients with CVST.

Intracranial atherosclerotic stenosis is a major cause of stroke and yet there are currently no proven effective treatments for it. The SAMMPRIS trial, comparing aggressive medical management alone with aggressive medical management combined with intracranial angioplasty and stenting, was prematurely halted when an unexpectedly high rate of periprocedural events was found in the endovascular arm. The goal of our study is to report the immediate and long-term outcomes of patients with ≥ 70 % symptomatic intracranial atherosclerotic stenosis treated with balloon angioplasty and stent placement in a single centre.This is a retrospective review of 37 consecutive patients with 42 procedures of ballon angioplasty and stenting for intracranial atherosclerotic stenosis (≥ 70 % stenosis) treated between 1999 and 2012. Technical success (residual stenosis ≤ 50 %), periprocedural success (no vascular complications within 72 hours), and long-term outcomes are reported.Technical and periprocedural success was achieved in 90.5 % of patients. The within 72 hours periprocedural stroke/death rate was 7.1 % (4.8 % intracranial haemorrhage), and the 30-day stroke/death rate was 9.5 %. Thirty patients (81 %) had clinical follow-up at ≥ 6 months. During follow-up, 5 patients developed 6 ischemic events; 5 of them (17 %) were ipsilateral. The restenosis rate was 27 %, and the retreatment rate was 12 %.Our outcomes of the balloon angioplasty/stent placement for intracranial atherosclerotic stenosis are better than those in the SAMMPRIS study and compare favourably with those in large registries and observational studies.Hintergrund: Die intrakranielle atherosklerotische Stenose ist eine der Hauptursachen von zerebralen Schlaganfällen, doch gibt es noch keine nachweislich wirksame Methode zu deren Behandlung. Die SAMMPRIS Studie verglich eine aggressive medikamentöse Behandlung mit einer aggressiven interventionellen Behandlung kombiniert mit intrakranieller Angioplastie und Stenting. Sie wurde vorzeitig abgebrochen, weil eine unerwartet hohe Zahl periprozeduraler Ereignisse im endovaskulären Studienarm auftrat. Das Ziel unserer Studie ist es, über die unmittelbaren und langfristigen Ergebnisse der Ballon-Angioplastie mit Stent-Implantation bei Patienten mit70 % symptomatischer intrakranieller atherosklerotischer Stenose an einem einzelnen Zentrum zu berichten. Patienten und Methoden: Dies ist eine retrospektive Analyse von 37 konsekutiven Patienten mit 42 Ballon-Angioplastien und Stenting, die zwischen 1999 und 2012 behandelt wurden. Technischer Erfolg (Reststenose ≤ 50 %), periprozeduraler Erfolg (keine vaskulären Komplikationen innerhalb von 72 Stunden) und Langzeit-Ergebnisse werden berichtet. Ergebnisse: Technischer und periprozeduraler Erfolg wurde in 90,5 % der Patienten erreicht. Periprozedural (bis 72 Stunden) traten Schlaganfall / Tod in 7,1 % (4,8 % intrakranielle Blutungen) ein, und die 30-Tage Rate an Schlaganfall/Tod betrug 9,5 %. Dreißig Patienten (81 %) konnten ≥ 6 Monate nachverfolgt werden. Während des Follow-up entwickelten 5 Patienten 6 ischämische Ereignisse, 5 von diesen (17 %) waren ipsilateral. Die Restenose-Rate betrug 27 %, 12 % wurden noch einmal behandelt. Schlussfolgerungen: Unsere Ergebnisse der Ballon-Angioplastie/Stent-Platzierung für intrakranielle atherosklerotische Stenosen sind besser als die in der SAMMPRIS Studie und vergleichbar mit denen in großen Registern und Beobachtungsstudien.

We report on a 72-year-old female with an unusual intracranial bleeding complication after an extracranial carotid artery stenting procedure performed for a tight left ICA stenosis associated with contralateral carotid occlusion. Two hours after the procedure, the initial signs of intracranial bleeding appeared that led to the patient's demise 5 days later. A brain CT showed and autopsy proved massive intraventricular bleeding. To our knowledge, our case is only the second report of isolated reperfusion intraventricular hemorrhage post-CAS.

Introduction Taxine alkaloids cause fatal poisoning, in particular due to the compound’s toxic effect on the cardiovascular apparatus. Case presentation We describe the case of a 39-year-old Caucasian man with common yew intoxication for whom cardiopulmonary resuscitation using all available methods, although delayed and extended, was successful. Conclusions Extended and delayed cardiopulmonary resuscitation can be used successfully to treat common yew intoxication.
