Stroke is the leading cause of physical disability, and thrombolysis is a promising treatment for acute ischaemic stroke. Alteplase has significant benefits for patients if it is administered within four and a half hours of stroke onset. This article uses a case study approach to explore a patient's journey through admission, triage, eligibility and administration of alteplase therapy. It emphasises the post-monitoring role of the nurse.
Alteplase is the only approved drug for the treatment of acute ischemic stroke, but it is offered to a minority of patients, not only because of the short therapeutic window but also because of the numerous contraindications associated with thrombolysis, such as thrombocytopenia. There is some controversy on the true risk associated with thrombolysis in patients with thrombocytopenia. Here we report the case of a young patient, who developed an in-hospital acute ischemic stroke involving a large territory o...
Given that alteplase has been the only approved thrombolytic agent for acute ischemic stroke for almost two decades, there has been intense interest in more potent and safer agents over the last few years. Tenecteplase is a bioengineered mutation of alteplase with advantageous pharmacodynamics and pharmacokinetics. The superiority of tenecteplase over alteplase has been proven by in vitro and animal studies, and it was approved for use in myocardial infarction more than a decade ago. In patients with acute ...
Pulmonary embolism can present with a wide range of symptoms, from asymptomatic to cardiac arrest, making diagnosis challenging. Alteplase is a fibrinolytic that is indicated for the treatment of pulmonary embolism in intermediate- and high-risk patients. Controversy exists as to the patient population that will benefit most from fibrinolytic therapy, as well as the proper dose and administration technique. The patient's risk of bleeding should be weighed against the potential benefits of treatment in light...
Currently, there are 2 strategies to increase the effect of systemic thrombolysis with alteplase (rtPA) in acute major stroke: endovascular treatment via stent retrieval and ultrasound enhancement (sonothrombolysis). This study compares these 2 approaches in patients with proximal intracranial occlusion of the anterior circulation.
A rare, yet serious, complication of mechanical heart valves is symptomatic obstructive prosthetic valve thrombosis. The risk of valve thrombosis is magnified in patients who are nonadherent to prescribed anticoagulation. In this case report, we describe a 48-year-old male patient with a history of mechanical aortic valve replacement surgery, who stopped taking prescribed warfarin therapy 2 years before presentation and subsequently developed acute decompensated heart failure secondary to valvular dysfuncti...
A 79-year-old woman with hypertension was evaluated 3 hours and 20 minutes after the sudden onset of left-sided weakness which lasted about 15 minutes and was followed by involuntary, coarse, flinging movements of the left extremities (hemiballistic), occurring every few minutes, and facial asymmetry. Brain computed tomography revealed no abnormalities. The patient received intravenous thrombolysis with 0.9 mg/kg of alteplase 4 hours after the symptom onset. Involuntary movements and central facial nerve pa...
Intravenous recombinant tissue plasminogen activator (alteplase) was approved by the US Food and Drug Administration in 1996 for the treatment of acute ischemic stroke. Nearly 20 years later, it remains the only approved treatment, despite limitations in both efficacy and safety. With a growing capacity for stroke treatment worldwide, physicians need to understand where we have come from and what the future of stroke treatment might be.
A 20-year-old male with asymptomatic inherited type 1 antithrombin deficiency and a family history of thrombosis started injecting himself with testosterone 250 mg intramuscularly twice weekly for 5 weeks. He presented to the hospital with progressive dyspnea on exertion, chest pain and hemoptysis. Workup revealed bilateral submassive pulmonary embolism and proximal right lower extremity deep vein thrombosis. He was treated with intravenous (IV) unfractionated heparin and underwent catheter-directed thr...
The rate of intravenous thrombolysis with tissue-type plasminogen activator or urokinase for stroke patients is extremely low in China. It has been demonstrated that a telestroke service may help to increase the rate of intravenous thrombolysis and improve stroke care quality in local hospitals. The aim of this study, also called the Acute Stroke Advancing Program, is to evaluate the effectiveness and safety of decision-making concerning intravenous thrombolysis via a telemedicine consultation system for ac...
To study the safety of off-label IV thrombolysis in patients with very severe stroke (NIH Stroke Scale [NIHSS] scores >25) compared with severe stroke (NIHSS scores 15-25), where treatment is within European regulations.
Approximately 10 years have passed since intravenous (IV) recombinant tissue plasminogen activator therapy was approved in Japan. The aim of this retrospective study was to identify the effectiveness and safety of IV alteplase therapy with the Japanese original dose around Hiroshima via consideration of the patients' backgrounds, examination findings, and outcomes.
Recanalization of an occluded intracranial artery is influenced by temperature-dependent enzymes, including alteplase. We assessed the relation between body temperature on admission and recanalization.
Intravenous thrombolysis increases disability-free survival after acute ischaemic stroke in a time-dependent fashion. We aimed to determine whether pre-hospital notification, introduction of a CT scanner near to assessment site and introduction of out-of-hours thrombolysis services affect thrombolysis timing. Methods Timings related to thrombolysis were collected between May 2012 and June 2014 at a single hospital site; these included time to stroke physician assessment, time to cranial CT imaging and door ...
Intravenous thrombolysis is considered to be standard of care for acute ischemic stroke patients arriving within 3-4.5 h of stroke symptom onset. Recently, endovascular therapies have been proposed to extend and enhance stroke outcomes by targeting large vessel occlusions. Different radiologic methods, time windows, and treatment tools have delineated differences between trials. Overall, intravenous thrombolysis remains the treatment of choice for all acute ischemic stroke patients, with a small subset ben...
Stroke is a leading cause of adult disability and mortality. Intravenous thrombolysis can minimize disability when patients present to the emergency department for treatment within the 3 - 4½ h of symptom onset. Blacks and Hispanics are more likely to die and suffer disability from stroke than whites, due in part to delayed hospital arrival and ineligibility for intravenous thrombolysis for acute stroke. Low stroke literacy (poor knowledge of stroke symptoms and when to call 911) among Blacks and His...
The impact of the side in middle cerebral artery (MCA) ischemic stroke is not well established. Our aim was to analyze the differences between right (RMCA) and left middle cerebral artery (LMCA) stroke in patients submitted to intravenous thrombolysis and the influence of the affected side in the patient's mortality after 3 months. Method Patients with MCA ischemic stroke submitted to intravenous thrombolysis from March 2010 to December 2011 at two Brazilian Stroke Centers were included. Differences between...
Thrombolytic treatment for acute ischaemic stroke improves prognosis, although there is a risk of bleeding complications leading to early death/severe disability. Benefit from thrombolysis is time dependent and treatment must be administered within 4.5 hours from onset of symptoms, which presents unique challenges for development of tools to support decision making and patient understanding about treatment. Our aim was to develop a decision aid to support patient-specific clinical decision-making about thr...
Thrombolysis for ischemic stroke has been increasing in the United States. We sought to investigate recent trends in thrombolysis use in older adults.
The drip and ship model is a method used to deliver thrombolysis to acute stroke patients in facilities lacking onsite neurology coverage. We sought to determine whether our drip and ship population differs from patients treated directly at our stroke center (direct presenters).
In recent years ischemic stroke caused by an intracranial vessel occlusion has become a treatable disease. Over decades intravenous thrombolysis by recombinant tissue plasminogen activator was the only accepted causal treatment of ischemic stroke supported by the results of randomized, controlled trials. However, there has been continuous development of endovascular treatment strategies over recent years. Today there are 5 prospective, randomized multicenter studies showing the highly significant superiorit...
The goal of the present study was to determine whether the presence or absence of parenchymal FLAIR hyperintensity alone, before thrombolysis, might be a predictive factor of ischemic stroke outcomes after the acute phase of stroke and at 3 months.
Perfusion computed tomography (PCT) has emerged as alternative to magnetic resonance imaging (MRI) for assessment of patients clinically qualifying for off-label thrombolysis within 4.5 to 9 hours after onset of ischemic stroke. However, disadvantage of PCT is its often limited anatomic coverage with only 2 or 3 slices when using a 4- to 64-section scanner. Our purpose was therefore to evaluate the value of 2- and 3-slice perfusion compared to whole-brain perfusion.
