RESUMO
BACKGROUND AND AIMS: The effect of surgical treatment for spontaneous intracerebral hemorrhage (ICH) remains uncertain. We conducted an observational retrospective cohort study on supra-centimeter spontaneous ICH treated with either neurosurgical or conservative management. The baseline demographics and risk factors were correlated with in-hospital mortality and 3 and 6-month survival rates stratified by management. METHODS: We included all patients with evidence of spontaneous ICH > 1 cm detected by CT and admitted between august 2020 and march 2021 to the "SMM" Hospital in Perugia. RESULTS: Onehundredandtwentytwo patients were included in the study, and 45% (n.55) were surgically treated. The mean age was 71.9 ± 15.3, and 61% (n.75) were males. Intra-hospital mortality ended up being 31% (n.38), 3 months-survival was 63% (n.77) and 6 months-survival was 60% (n.73). From the multivariate analysis of the surgical patients versus medical patient, we observed that the surgical patients were younger (67.5 ± 14.9 vs 75.5 ± 14.7 y; OR 0.87; Cl 95% 0.85-0.94; p 0.001), with greater ICH volume at the onset (61 ± 39.4 cc vs 51 ± 64 cc; OR 1.03; Cl 95% 1.005-1.07; p 0.05), more midline shift (7.61 ± 5.54 mm vs 4.09 ± 5.88 mm; OR 1.37; Cl 95% 1.045-1.79; p 0.023), and a higher ICH score (3 vs 2 mean ICH score; OR 21.12; Cl 95% 2.6-170.6; p 0.004). Intra-hospital mortality in the surgical group and in the conservative treatment group was respectively 33% vs 30%, 3 month-survival was 64% vs 63% and 6 month- survival were 60% in both groups. CONCLUSIONS: Our patient cohort shows no overall benefit from surgery over conservative treatment, but surgical patients were younger and had larger ICH volume.

BACKGROUND AND PURPOSE: Transient global amnesia (TGA) is characterized by a sudden onset of anterograde amnesia lasting up to 24 h. One major differential for TGA is transient epileptic amnesia, which typically lasts < 1 h. However, TGA can also be short in duration and little is known about the time trends, characteristics and prognosis of TGA cases lasting < 1 h. METHODS: We compared the clinical features of TGA ascertained in two independent cohort studies in Oxfordshire, UK [Oxford cohort 1977-1987 versus Oxford Vascular Study (OXVASC) 2002-2018] to determine the time trends of clinical features of TGA. Results were validated in another independent contemporary TGA cohort in Italy [Northern Umbria TGA registry (NU) 2002-2018]. We compared the risk factors, clinical features and long-term prognosis (major cardiovascular events, recurrent TGA and seizure/epilepsy) of patients presenting with episodes lasting < 1 h versus those lasting ≥ 1 h. RESULTS: Overall, 639 patients with TGA were included (114 Oxford cohort, 100 OXVASC, 425 NU). Compared with the original Oxford cohort, there were more cases with TGA lasting < 1 h in OXVASC [32 (32.0%) vs. 9 (8.8%)] and NU (11.8% vs. 8.8% in Oxford cohort). In both OXVASC and NU, patient age, vascular risk factors and clinical features were largely similar between those with TGA lasting < 1 h versus those lasting ≥ 1 h. Moreover, there was no difference in the long-term risk of seizure/epilepsy or major cardiovascular events between TGA lasting < 1 h versus TGA lasting ≥ 1 h. CONCLUSIONS: Short-duration TGA episodes (<1 h) were not uncommon and were more frequent than in earlier studies. The clinical features and long-term prognosis of short-duration TGA did not differ from more typical episodes lasting ≥ 1 h.

AIM: The role of anticoagulants for the prevention of venous thromboembolism in acute hemorrhagic stroke is uncertain. We performed an updated meta-analysis of studies to obtain the best estimates of the efficacy and safety of anticoagulants for the prevention of venous thromboembolism in patients with acute hemorrhagic stroke. METHODS: Using electronic and manual searches of the literature, we identified randomized and non-randomized studies comparing anticoagulants (unfractionated heparin or low-molecular-weight heparin or heparinoids) with treatments other than anticoagulants (elastic stockings, intermittent pneumatic compression or placebo) in patients with acute hemorrhagic stroke. Study outcomes included symptomatic and asymptomatic deep venous thrombosis (DVT), symptomatic and asymptomatic pulmonary embolism (PE), any hematoma enlargement or death. Risk ratios (RRs) for individual outcomes were calculated for each study and data from all studies were pooled using the Mantel-Haenszel method. RESULTS: Four studies (two randomized) involving 1000 patients with acute hemorrhagic stroke met the criteria for inclusion in this meta-analysis. Compared with other treatments, anticoagulants were associated with a significant reduction in PE (1.7% vs. 2.9%; RR, 0.37; 95% CI, 0.17-0.80; P = 0.01), a DVT rate of 4.2% compared with 3.3% (RR, 0.77; 95% CI, 0.44-1.34; P = 0.36), an increase in any hematoma enlargement (8.0% vs. 4.0%; RR, 1.42; 95% CI, 0.57-3.53; P = 0.45), and a non-significant reduction in mortality (16.1% vs. 20.9%; RR, 0.76; 95% CI, 0.57-1.03; P = 0.07). CONCLUSIONS: Our findings indicate that in patients with hemorrhagic stroke, early anticoagulation is associated with a significant reduction in PE and a non-significant reduction in mortality, with the trade-off of a non-significant increase in hematoma enlargement. These results must be taken with caution and should encourage the assessment of the clinical benefit of antithrombotic prophylaxis in patients with cerebral bleeding by properly designed clinical trials.

BACKGROUND: Studies in experimental animals have suggested that antithrombotic agents may have a neuroprotective effect after an ischemic injury. The aim of this study was to analyze the effect of prior use of antithrombotic agents (antiplatelets or anticoagulants) on neurological functional outcome in patients with acute ischemic stroke. SUBJECTS AND METHODS: Consecutive patients included in the Perugia Stroke Registry were considered for this analysis. Neurological functional outcome was evaluated at discharge using the modified Rankin Scale (mRS >or= 3 disabling stroke). RESULTS: Of the 1921 patients included in the analysis (mean age 76.3 +/- 12.5 years; 53% males), 662 (34.5%) were on antithrombotic treatment (581 antiplatelets, 71 anticoagulants and 10 antiplatelets associated with anticoagulants). One hundred and twenty-two patients (6.4%) died in hospital; at discharge 712 patients (37.1%) were disabled and 1,087 patients (56.6%) were non-disabled. Fifty-four (44.3%) of the deceased patients and 270 (37.9%) of disabled patients were on antithrombotic treatment, while 338 (31.1%) non-disabled patients were taking antithrombotic agents. From multivariate analysis, age and stroke severity were associated with an adverse outcome. Male gender, dyslipidemia, stroke due to small vessel disease and no history of previous stroke were associated with an improved outcome, while no correlation was found between prior use of antithrombotic agents and outcome (mortality odds ratio; OR = 1.32, 95% confidence interval; CI 0.85-2.04; P = 0.20, mortality or disability OR = 0.95, 95% CI 0.72-1.25; P = 0.80). CONCLUSION: Prior use of antithrombotic agents does not improve the functional outcome in patients with acute ischemic stroke.

BACKGROUND AND PURPOSES: Atrial fibrillation (AF) is an independent risk factor for stroke. The aims of this study were to assess: (i) the frequency of known or unknown AF in patients admitted to the hospital for a first-ever ischemic stroke and whether AF is associated with an adverse outcome at discharge (death or disability); (ii) the rates and determinants for the use of antithrombotic agents before stroke in patients with known AF and the adherence to the current treatment guidelines; and (iii) whether the lack of adherence to the current guidelines is associated with adverse outcome at discharge. METHODS: Consecutive patients with acute first-ever stroke admitted to an individual Stroke Unit between January 2000 to December 2003, were included in the study. Twelve-lead electrocardiogram (ECG) was performed in all patients on admission. Functional outcome was measured at discharge according to modified Rankin Score. RESULTS: A total of 1549 patients were included in the study: 238 patients (15.4%) were known to have AF and 76 (4.9%) were diagnosed with AF (unknown) on ECG performed on admission. At discharge 91 patients (5.9%) had died and 605 patients (39.0%) had died or were functionally dependent. Multivariate analysis showed that AF on admission was correlated with mortality or disability (OR = 1.58, 95% CI 1.09-2.30, P = 0.015). Before stroke, 124 out of 238 patients with known AF (52.1%) were not on antithrombotic therapy, 83 (34.9%) were receiving antiplatelet and 31 (13.0%) anticoagulant treatment. Previous transient ischemic attack, history of ischemic heart disease and hyperlipidemia were associated with the use of antithrombotic therapy. Only 24 out of 114 patients on antithrombotic treatment on admission were adequately treated according to the current guidelines. Of the adequately treated patients, 41.7% died or were disabled at discharge respect to 52.3% of the patients non-adequately treated (RR = 0.80, 95% CI 0.48-1.30). CONCLUSIONS: AF (on history or new diagnosis) was present in 20.3% of the patients with first-ever stroke admitted to a Stroke Unit and it was associated with increased mortality or disability. Only 10% of patients with known AF were previously receiving an adequate antithrombotic treatment according to current guidelines.

BACKGROUND: Some investigators have stated that monoparesis is almost never the result of a lacunar infarct or cerebral haemorrhage. OBJECTIVE: To describe the topography and aetiology in a consecutive population where first ever stroke was manifested by isolated monoparesis. METHODS: Patients with motor paresis of only one limb were included consecutively in the study. A neuroradiologist determined stroke location, while a neurologist reviewed the clinical records to assign stroke subtype. Both physicians worked blind to each other's findings. RESULTS: 51 of 2003 patients (2.5%) had isolated monoparesis, and of these 39 (76.5%) were ischaemic strokes and 12 (23.5%) were haemorrhagic. Cardioembolism was the cause of stroke in 15.7%, atherosclerosis in 9.8%, and small artery disease in 39.2%. Most of the haemorrhages were in the thalamic-capsular region (5/12). Most of the ischaemic lesions were in the deep territory of the middle cerebral artery, the corona radiate, or the centrum semiovale (20/39); 16 of 39 were in the cortical territories or the watershed region. CONCLUSIONS: Isolated monoparesis is a rare symptom in stroke patients and is often caused by small artery disease or a small haemorrhage.

UNLABELLED: We studied the correlation between the potential causes of stroke (TOAST etiological groups) and the involvement of different vascular territories seen on computed tomography (CT) scans in patients with ischemic stroke. Information from consecutive patients with a first-ever stroke have been prospectively coded and entered into a computerized data bank (Perugia Stroke Registry). A population of 1,719 patients were evaluated: 1,284 patients (74.7%) had ischemic stroke. Large artery disease was the main cause of entire middle cerebral artery (MCA) territory infarcts (40.9%), superficial MCA territory infarcts (35.7%), and watershed infarcts (68.2%). The highest presence of emboligenic heart disease was found in the entire MCA territory infarcts (28.8%) or superficial (29.4%) supratentorial infarcts and in cerebellar infarcts (36.8%). Small artery disease was the most common presumed cause of deep MCA infarcts (75.0%) and posterior cerebral artery (PCA) territory infarcts (52.1%). IN CONCLUSION: stroke location could depend on its etiology. Lacunar infarcts are the most prevalent (36.7%), being mostly localized in the deep MCA territory; large artery disease includes more than two-thirds of watershed infarcts; the most prevalent territories involved in cardioembolic stroke are the entire MCA and posterior fossa.
