Aneurysmal subarachnoid haemorrhage in pregnancy: a case series

Pregnancy is a recognized risk factor for aneurysmal subarachnoid hemorrhage (SAH). Headache is very frequent in normal pregnancy and it is a common sign shared between several intracranial diseases. We present a case series of 10 women in the third trimester of pregnancy admitted to our intensive care unit (ICU) with neurological signs and symptoms. 4 of these patients were diagnosed with SAH. Data in this study suggest that a timely diagnosis and an appropriate treatment is crucial for mother and baby

Acute ischemic stroke with cervical internal carotid artery steno-occlusive lesion: multicenter analysis of endovascular approaches

open14noBackground Occlusions of internal carotid artery (ICA), whether isolated or in tandem lesions (TL) have a poor response to treatment with intravenous thrombolysis. Previous studies ​​have demonstrated the superiority of mechanical thrombectomy in the treatment of acute ischemic stroke (AIS) following large vessel occlusion, compared to standard intravenous fibrinolysis. The aim of our study was to describe endovascular treatment (EVT) in AIS due to ICA occlusion, whether isolated or in TL. Methods we assessed the association between 90-day outcome and clinical, demographic, imaging and procedure data in 51 consecutive patients with acute isolated ICA or TL occlusion who underwent endovascular treatment (EVT). We evaluated baseline NIHSS and mRS, ASPECTS, type of occlusion, stent placement, use of stent retrievers and/or thromboaspiration, duration of the procedure, mTICI, procedural therapy and complications. Results A favorable 90-day outcome (mRS 0–2) was achieved in 34 patients (67%) and was significantly associated with the use of dual antiplatelet therapy after the procedure (p = 0.008), shorter procedure duration (p = 0.031), TICI 2b-3 (p < 0.001) and lack of post-procedural hemorrhagic transformation (p = 0.001). Four patients did not survive, resulting in a mortality rate of 8% Conclusions EVT in the treatment of AIS due to ICA occlusion is safe and effective; mortality rates are in agreement with the current literature. The use of the stent is safe and promotes good angiographic results, as well as therapy with a GpIIb / IIIa inhibitor immediately after stent release which is also associated with better 3-month outcome and good revascularization.openLuigi Cirillo, Daniele Giuseppe Romano, Gianfranco Vornetti, Giulia Frauenfelder, Chiara Tamburrano, Francesco Taglialatela, Salvatore Isceri, Renato Saponiero, Rosa Napoletano, Mauro Gentile, Michele Romoli, Ciro Princiotta, Luigi Simonetti, Andrea ZiniLuigi Cirillo, Daniele Giuseppe Romano, Gianfranco Vornetti, Giulia Frauenfelder, Chiara Tamburrano, Francesco Taglialatela, Salvatore Isceri, Renato Saponiero, Rosa Napoletano, Mauro Gentile, Michele Romoli, Ciro Princiotta, Luigi Simonetti, Andrea Zin

Technical note and first results on JET 7 thromboaspiration device for T-ICA occlusions

Abstract Background To describe technical features and initial results of a novel large-bore reperfusion catheter as first thromboaspiration approach for endovascular stroke treatment in terminal internal carotid artery (T-ICA) occlusions. Methods All patients treated with A Direct Aspiration first-Pass Technique (ADAPT) using JET 7 “Standard Tip” Penumbra Reperfusion catheter for acute T-ICA occlusion were retrospectively included in the study. Baseline data, puncture to recanalization time, number of attempts, switch to second device/technique rate and successful recanalization rate were assessed. Successful recanalization was defined by a thrombolysis in cerebral infarction (TICI) score ≥ 2b and favorable functional outcome was defined according to modified Rankin scale (score, 0–2). Catheter specifics and thromboaspiration reperfusion technique with JET 7 were reported. Results A total of 21 patients who underwent ADAPT with JET 7 Reperfusion catheter were enrolled for the final analysis. ADAPT was performed as first approach in all cases (100%). First attempt successful recanalization (eTICI ≥2b) was obtained in 90,5% of cases. Mean puncture to recanalization time was 16 minutes. Final successful recanalization was reached in 96.5%. Functional independence at 90 was achieved in 57,1% cases. Symptomatic intracranial hemorrhage occurred in one patient within 24 h. Conclusion The large-bore JET 7 reperfusion catheter could be considered as first-line in patients with acute T-ICA occlusion, allowing rapid recanalization and low rate of rescue therapy with stent retriver. Further series and/or trial evaluation are required to confirm our results

Cortical pattern of reduced perfusion in hearing loss revealed by ASL-MRI

Age-related hearing loss (HL) can be related to brain dysfunction or structural damage and may result in cerebral metabolic/perfusion abnormalities. Arterial spin labeling (ASL) magnetic resonance imaging (MRI) allows investigating noninvasively brain perfusion changes. Pseudocontinuous ASL and T1-weighted MRI (at 3 T) and neuropsychological testing (Montreal Cognitive Assessment) were performed in 31 HL (age range = 47-77 years, mean age ± SD = 63.4 ± 8.4 years, pure-tone average [PTA] HL > 50 dB) and 28 normal hearing (NH; age range = 48-78 years, mean age ± SD = 59.7 ± 7.4 years) subjects. Cerebral blood flow (CBF) and gray matter volume (GMV) were analyzed in the cortical volume to assess perfusion and structural group differences. Two HL subjects showing cognitive impairment were excluded from group comparisons. No significant differences in either global or local atrophy were detected between groups but the HL group exhibited significant regional effects of reduced perfusion within the bilateral primary auditory cortex, with maximal CBF difference (-17.2%) in the right lateral Heschl's gyrus. For the whole sample of HL and NH subjects (n = 59 = 31 HL + 28 NH), the regional CBF was correlated positively to the regional GMV (p = 0.020). In HL subjects (n = 31), the regional CBF was correlated negatively to the audiogram steepness (frequency range: 2-4 kHz, right ear: p = 0.022, left ear: p = 0.015). The observed cortical pattern of perfusion reduction suggests that neuronal metabolism can be related to HL before the recognition of brain structural damage. This also illustrates the potential of ASL-MRI to contribute early functional markers of reduced central processing associated with HL

Efficacy of ADAPT with large-bore reperfusion catheter in anterior circulation acute ischemic stroke: a multicentric Italian experience

A direct aspiration first pass technique (ADAPT) is an alternative technique as first-line thrombectomy for large vessel occlusion in acute ischemic stroke, still debated when compared to first-line stent retriever. To retrospectively evaluate technical and clinical outcomes of the ADAPT as first-line treatment for anterior circulation acute ischemic stroke with large-bore reperfusion catheters

The Impact of Covid-19 Lockdown on Stroke Admissions and Treatments in Campania

Objectives: The enforcement of complete lockdown with home confinement has been necessary to limit SARS-CoV-2 contagions in Italy, one the most affected countries worldwide. Simultaneously, in several Emergency Departments, a reduction in cardio- and cerebrovascular presentations was noticed. This study analyses the impact of Covid-19 pandemic and lockdown measures on the incidence of stroke, in Campania, the most densely-populated region in Italy. Materials and Methods: We retrospectively analyzed data regarding acute stroke patients presenting at 5 Campania stroke hubs, before and after the issue of lockdown in Italy on March 9th, 2020. Results: Compared to the pre-lockdown, we observed a significant reduction in the number of acute reperfusion treatments in stroke (P for interact 0.001); however the global number of patients presenting with acute stroke did not significantly differ. The time to reach medical attention was significantly longer in the lockdown phase (230 versus 154 min, P 0.016). For patients who underwent acute reperfusion treatment we also observed significantly longer time-to-imaging (30 versus 40 min, P 0.0005) and a trend to longer time-to-needle (75 versus 90 min P 0.23), but not time-to-groin. Conclusions: This study showed the reduction in acute reperfusion treatments for acute ischemic stroke and the slowdown of stroke pathways, during the lockdown phase of Covid-19 pandemic, in Campania, the third-most-populous and the most-densely populated Italian Region. In the next future, the risk for high-grade disability and death, due to delayed or even avoided hospital presentation due to fear of contagion, may be high
