BACKGROUND:The effectiveness of intravenous thrombolysis (IVT) before endovascular treatment (EVT) has been investigated in randomized trials and meta-analyses. These studies mainly concerned anterior circulation occlusions. All patients with a posterior circulation occlusion were included.
Circulation: Cardiovascular Interventions, Ahead of Print. BACKGROUND:Prior clinical trials have demonstrated the efficacy of ultrasound-facilitated catheter-directed thrombolysis (USCDT) for the treatment of acute intermediate-risk pulmonary embolism (PE) using reduced thrombolytic doses and shorter infusion durations.
Introduction:Strokes affecting the posterior circulation (PCS) account for 20% of all ischemic strokes. Recent studies indicate that PCS are half as likely to receive thrombolytic therapy and threefold less likely to receive intervention with mechanical thrombectomy compared to anterior circulation strokes (ACS). in 2021, 37.5
ConclusionsIn thrombectomy‐eligible patients with anterior circulation large‐vessel occlusion, IVT improves functional outcome independent of grade of reperfusion and distal thrombus migration. to –0.17];P=0.002) and remained beneficial in those with unsuccessful reperfusion (mTICI ≤2a; ß=–0.47 [95% CI, −0.96 to 0.01];P=0.05).ConclusionsIn
Background:Patients with acute ischemic stroke and a large vessel occlusion (LVO) admitted to primary stroke centers (PSC) often require inter-facility transfer for thrombectomy.
Background and Aims:Endovascular treatment (EVT) alone has been confirmed to be non-inferior to intravenous thrombolysis (IVT) followed with EVT in acute ischemic stroke (AIS) due to large-vessel occlusion of the anterior circulation. Stroke, Volume 56, Issue Suppl_1 , Page AWP253-AWP253, February 1, 2025.
IntroductionIntracranial atherosclerotic disease (ICAD) is associated with up to 32% of posterior circulation strokes.1 Rescue treatment with stenting, balloon angioplasty, and/or intraarterial thrombolysis or antiplatelets are often required to treat the underlying stenosis.
Posterior circulation tandem occlusion was defined as stroke due to intracranial vertebral (V4), basilar, or posterior cerebral artery (PCA) occlusions, with tandem steno-occlusive lesion >70% of the extracranial vertebral artery and impaired distal flow or partial filling of the VA from collaterals.
Introduction:Large vessel recanalization (LVR) is a well described phenomenon following intravenous thrombolysis (IVT). Better collateral circulation was independently associated with both higher odds of LVR, as well as lower odds of infarct progression. Higher Tan CS was significantly associated with higher odds of LVR (2.95 [95%CI 1.60-5.45],
However, tPA is a more complex enzyme than expected, being for instance able to promote thrombolysis, but at the same time, also able to influence neuronal survival and to affect the integrity of the blood-brain barrier. In this context, the impact of endogenous parenchymal tPA is limited.
The retraction has been issued at the authors’ request.Patel et al Anterior Circulation Thrombectomy in Patients With Low National Institutes of Health Stroke Scale Score: Analysis of the National Inpatient Sample. Specifically, the variables for endovascular therapy and intravenous thrombolysis were mistakenly switched. 2023, e000998.
P < 0.001) and more likelihood of achieving Thrombolysis in Cerebral Infarction 3 (79.5% Use of intravenous tissue‐type plasminogen activator, hypertension, final Thrombolysis in Cerebral Infarction 3, and lower baseline National Institutes of Health Stroke Scale score were independent predictors of functional outcome.
During spontaneous reperfusion -- whether via thrombolysis, or recruitment of collateral circulation -- there exists characteristic ST/T changes on the ECG. Coronary thrombosis is a dynamic process of platelet aggregation and subsequent coagulation. Case Review: [link]
In the external set, patients with LVO treated with endovascular therapy achieving modified Thrombolysis in Cerebral Infarction score 2b and available baseline NCCT, CT angiography, and CT perfusion were included.RESULTSA total of 2858 studies of patients with stroke alerts were used for training (80%) and internal validation (20%).
Background:The effectiveness and safety of intravenous Tirofiban as an adjunct to endovascular therapy (EVT) in posterior circulation patients with tandem lesions (PCTL) remain uncertain.Methods:This study utilized individual patient data pooled from two multicenter observational studies: the BASILAR and the PERSIST registries.
In multivariable models, intravenous thrombolysis was independently associated with higher odds of routine discharge (adjusted OR, 1.78; 95% CI, 1.57–2.01;P<0.001) Patients treated with intravenous thrombolysis had greater odds of routine discharge. P<0.001) and higher rates of death (adjusted OR, 2.11; 95% CI, 1.20–3.70;P
Twenty-three (88%) patients received IV thrombolysis and 7 (27%) had mechanical thrombectomy. Conclusions:This study found the acute stroke response for circulating inflammatory factors IFN, IL-17 and IL-2 correlated with stroke lesion volume and IFN correlated with severity on the NIHSS. Median lesion volume on MRI was 1.4
Nineteen (68%) MSU patients were diagnosed as stroke, with 17 (61%) confirmed and 2 likely TIA or stroke averted by thrombolysis; 9 were stroke mimics. Median initial NIHSS score was 7 (range 1-22) and 12 (71%) received intravenous thrombolysis with tPA or TNK. IL-6 was independent of lesion volume and NIHSS.
Purpose:Clot Burden Score (CBS) is a semiquantitative measure of thrombus extent on CTA for proximal anterior circulation strokes whose relationship with perfusion metrics has not been fully explored. Final infarct ASPECTS were scored for those without thrombolysis or thrombectomy.
Clinical outcomes were assessed using uni- and multivariable logistic regression models.Results:A total of 216 patients were included, with target vessels located within the anterior circulation (133; 63.4%) and posterior circulation (79; 36.6%). 10.43, p=0.0325).Conclusions:The

Random-effect models in a meta-analysis were employed to get the pooled risk ratios (RRs) and their corresponding 95% confidence intervals (95% CI) for sICH with MT, compared to other reperfusion treatment regimens, including best medical treatment and intravenous thrombolysis (IVT).Results:MT 2.07; P = 0.037). 1.03; P = 0.079).
Circulation: Cardiovascular Interventions, Ahead of Print. BACKGROUND:It is uncertain whether adjunctive thrombolysis is beneficial for patients with ST-segment–elevation myocardial infarction undergoing percutaneous coronary intervention (PCI) within 120 minutes of presentation. The median symptom to thrombolysis time was 252.5
We included AIS patients treated with MT for ICA, M1, or M2 occlusion with successful recanalization (modified Thrombolysis in Cerebral Infarction [mTICI] score ≥ 2C) and procedure durations under 60 minutes. FR was defined as successful recanalization with 90-day modified Rankin Scale (mRS) 3-6.
The primary outcome measure was successful recanalization defined as modified Thrombolysis in Cerebral Ischemia (mTICI) score of 2b or higher. Data from 29 stroke centers for 10,229 AIS patients treated with MT for LVO between January 2010 and December 2022 was investigated.
Is primary PCI superior to thrombolysis in the first hour of STEMI ? The fact of the matter is, at best, pPCI fights for equipoise in the first hour, but thrombolysis is a clear winner in moral, scientifc & holistic perspective, as it can be administered very early, at a fraction of cost ,independent of expertise and infrastructure.
The bootstrap resampling method was considered internal validation of the model.Results:Age (< 70 years), premorbid status (mRS 0), National Institutes of Health Stroke Scale (NIHSS) (< 20), and recanalization status after the MT (modified Thrombolysis in Cerebral Ischemia [mTICU] ≥2b) were related to 90-day mRS 0-3.
12% of the cohort (n=34) had posterior circulation stroke. Area under the receiver operating characteristic curve (AUC) with its 95% confidence interval was calculated for each prognostic model.Results:A total of 279 patients were included in this study. Of those, 43% (n=119) were male. Median age (IQR) was 69 (57-80) years.
Trichosanthes pericarpium is a well-known Chinese traditional herb described with the effect of activating blood circulation to dissipate blood stasis and improve blood circulation. However, its effects on microcirculation in patients with AMI after primary PCI remain unknown.
