Acute myocardial infarction (AMI) is uncommon in the acute phase of acute ischemic stroke (AIS) and occurs in approximately 1% of the population. Here, we report a paradoxical case of AMI during tissue plasminogen activator (t-PA) infusion for AIS. We review and analyze the previously reported cases. We found that only patients with AMI which occurred after thrombolytic therapy for AIS who received an adequate combination of anticoagulation plus percutaneous coronary intervention survived their events. Several mechanisms have been proposed for the development of AMI after thrombolytic therapy...

Objective Intraventricular hemorrhage (IVH) is a negative prognostic factor in intracerebral hemorrhage (ICH) and is associated with permanent shunt dependency in a substantial proportion of patients after ICH. IVH treatment by intraventricular fibrinolysis (IVF) was recently linked to reduced mortality rates in the CLEAR III study and IVF represents a safe and effective strategy to hasten clot resolution that may reduce shunt rates. Additionally, promising results from observational studies reported reductions in shunt dependency for a combined treatment approach of IVF plus lumbar drains (LD)...

BACKGROUND: The Interventional Management of Stroke III (IMS-III) trial demonstrated no benefit for intravenous recombinant tissue plasminogen activator (IV rt-PA) followed by endovascular therapy versus IV rt-PA alone. However, IMS-III mostly included earlier generation devices. The recent thrombectomy trials have incorporated the stent-retriever technology, but their generalizability remains unknown. METHODS: The North American Solitaire Acute Stroke (NASA) registry recruited patients treated with the Solitaire FR™ device between March 2012 and February 2013...

We herein report three ischemic stroke patients who underwent emergency carotid artery stenting after receiving intravenous tissue plasminogen activator (t-PA) treatment. All patients received antiplatelet medications immediately before stent placement for loading as well as dual antiplatelet therapy after stenting. Under high-dose and dual antiplatelet therapy, none of the three patients showed symptomatic intracranial hemorrhaging. However, one case showed reocclusion of the placed stent after acute thrombosis...

Cardiovascular disorders are on the rise worldwide due to alcohol abuse, obesity, hypertension, raised blood lipids, diabetes and age-related risks. The use of classical antiplatelet and anticoagulant therapies combined with surgical intervention helped to clear blood clots during the inceptive years. However, the discovery of streptokinase and urokinase ushered the way of using these enzymes as thrombolytic agents to degrade the fibrin network with an issue of systemic hemorrhage. The development of second generation plasminogen activators like anistreplase and tissue plasminogen activator partially controlled this problem...

Tissue plasminogen activator (t-PA) is the only FDA approved drug for acute ischemic stroke treatment, but its clinical use is limited due to the narrow therapeutic time window and severe adverse effects, including hemorrhagic transformation (HT) and neurotoxicity. One of the potential resolutions is to use adjunct therapies to reduce the side effects and extend t-PA's therapeutic time window. However, therapies modulating single target seems not satisfying, and a multi-target strategy is warranted to resolve such complex disease...

Heparin and thrombolytic agents such as tissue plasminogen activator (t-PA) are frequently used to prevent and treat occluded hemodialysis (HD) catheters. Thrombolytic agents have not been well studied for systemic effects. We present a post-operative neurosurgical patient who experienced a symptomatic intracranial hemorrhage (ICH) after t-PA was used to treat an occluded HD catheter. This case highlights that using t-PA to treat dysfunctional catheters may be associated with ICH in neurosurgical patients. Management strategies are discussed with a review of pertinent literature...

OBJECTIVE: We recently described TURN (Thrombolysis risk Using mRS and NIHSS), a computationally simple tool for predicting symptomatic intracerebral hemorrhage (sICH) after IV thrombolysis (rt-PA). Our objective was to compare TURN to existing scores for predicting sICH. METHODS: Our internal dataset consisted of 210 ischemic stroke patients receiving IV rt-PA from January 2009 until July 2013 at Yale New Haven Hospital. Our external dataset included 303 patients who received IV rt-PA during the NINDS rt-PA trial...

The treatment options for high risk acute pulmonary embolism (PE) patients with failed systemic thrombolytic treatment (STT) is limited. The clinical use of catheter directed thrombolysis with the EkoSonic Endovascular System (EKOS) in this population has not been evaluated before. Catheter directed thrombolysis is an effective treatment modality for high risk PE patients with failed STT. Thirteen consecutive patients with failed STT were included in the study. EKOS catheters were placed and tissue plasminogen activator (t-PA) in combination with unfractionated heparin were given...

BACKGROUND: Known risk factors for intracerebral hemorrhage (ICH) include age, hypertension, smoking, alcohol intake, and anticoagulant use. Some previous reports have indicated that hemostatic factors measured many years before the onset of ICH might predict the later occurrence of ICH. The objective of this analysis was to test whether selected hemostatic factors measured years before the onset of ICH could identify patients at higher risk for future ICH. METHODS: We performed a nested case-control study within the Women's Health Initiative (WHI) cohort...

One of the primary strategies for the management of acute ischemic stroke is intravenous (IV) thrombolysis with tissue plasminogen activator (t-PA). Over the past decade, endovascular therapies such as the use of stent retrievers to perform mechanical thrombectomy have been found to improve functional outcomes compared to t-PA alone. We aimed to reassess the functional outcomes and complications of IV thrombolysis with and without endovascular treatment for acute ischemic stroke using conventional meta-analysis and trial sequential analysis...

AIM: Women with pre-eclampsia (PE), placenta previa (PP), placental abruption (PA), and placental mesenchymal dysplasia (PMD) have been described as having placental permeability dysfunction. This study was performed to determine whether occult fetomaternal hemorrhage (FMH) is common in women with such complications and in women with non-reassuring fetal status. METHODS: Forty-one antenatal and 39 postnatal blood samples were obtained from 46 women, including 11 with placental permeability dysfunction (5, 3, 2, and 1 with PE, PP, PA, and PMD, respectively) and 35 controls without such complications...

Recombinant tissue plasminogen activator (t-PA) is the only FDA approved therapy for acute ischemic stroke. Cerebral microbleeds (CMBs) or cerebral amyloid angiopathy (CAA) are currently not contraindications, however, data regarding this complex issue are limited. We report 2 cases of fatal intracerebral hemorrhage (sICH) after IV t-PA, each with evidence of CAA. Patients with CAA may have increased risk for IV thrombolysis-associated sICH. We highlight the severe and catastrophic pattern of ICH, which may be a defining characteristic, and discuss the limitations of our current understanding of the risk of thrombolysis-associated ICH in patients with CAA and/or CMBs...

BACKGROUND: Patients may experience stroke while being admitted to the hospital (in-hospital stroke (IHS)) and they may be important candidates for reperfusion therapy. IHS patients may have various comorbidities and show worse outcomes compared with patients with an out-of-hospital stroke (OHS). On the other hand, the time from onset to treatment may be shorter in IHS patients than OHS patients. Most outcome studies of reperfusion therapy have been based on findings in OHS patients, and little information is currently available regarding outcomes of IHS, whether the outcomes differ between patients with IHS and those with OHS who receive reperfusion therapy...

BACKGROUND AND PURPOSE: The most feared complication after treatment with recombinant tissue-plasminogen activator (rt-PA) is the occurrence of symptomatic intracerebral hemorrhage (sICH). The aims of the study were to predict the risk of sICH (ECASS II definition) after a therapy with rt-PA and to examine whether associations exist between SEDAN score and the early mortality in patients with acute ischemic stroke in a monocenter study. METHODS: During a 6-year period (2008-2013), 542 consecutive stroke patients (mean age, 73 ± 3 years; 51...
