Mechanical Thrombectomy for Acute Ischemic Stroke: A Case Study Using the Penumbra Stroke System

Abstract: Over recent years, there have been dramatic advances in the ability to treat an acute ischemic stroke. Thrombolysis with intravenous recombinant tissue plasminogen activator can now be performed up to 4.5 hr after stroke onset in certain circumstances, and new mechanical thrombectomy devices allow intervention up to and beyond 8 hr in some instances. The Penumbra Stroke System (Penumbra Inc., Alameda, CA), one of these mechanical thrombectomy devices, uses a series of catheters to aspirate thrombus from occluded cerebral arteries and thus restore flow to the adjacent ischemic brain.This case study highlights the clinical and procedural issues involved in the treatment and postprocedural care of a patient with an acute ischemic stroke treated with the Penumbra Stroke System.

AbstractThe Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is widely used for the assessment of early ischemic changes (EICs) before thrombolysis. However, for symptomatic intracerebral hemorrhage (sICH) following intravenous recombinant tissue plasminogen activator (rt-PA), the prediction abilities of CT-ASPECTS, diffusion-weighted imaging (DWI)-ASPECTS, and DWI-ASPECTS including EICs in deep white matter (DWI-ASPECTS  + W) are unclear. We investigated associations between each score and sICH following intravenous rt-PA. Data from consecutive patients who received intravenous rt-PA for acut...

Carotid artery disease is a well-known cause of stroke. In Malaysia, stroke is the third most common cause of death [1]. To our knowledge, there is still limited information regarding stroke and its associated risk factors. Strokes from ischemic infarction of the brain is due to narrowing or occlusion from local thrombosis or embolization of a proximal thrombus. The incidence of ischemic stroke from carotid artery stenosis in an asymptomatic western population is approximately 2.7% according to a report from Netherlands by Hartog et al.

In conclusion, tetramethylpyrazine protected BMECs and inhibited platelets adhesion to BMECs after OGD/R injury, which was partially mediated by inhibiting P38 MAPK and NF-κB signaling pathways.

ConclusionThe polymorphisms Glu298Asp and C677T, affecting the eNOS and 5,10-MTHFR enzymes, respectively, and smoking, hypertension, and family history of stroke were associated with ischaemic stroke in young Mexican patients; this was not the case for the Thr325Ile, Ala147Thr, 4 G/5 G, and PLA1/A2 polymorphisms of the genes coding for fibrinolytic proteins and platelet receptors.ResumenIntroducciónDiversos polimorfismos en genes candidatos que codifican proteínas del sistema hemostático se han propuesto como factores de riesgo para el desarrollo de trombosis.MétodosCasos y controles, ...

Complete spontaneous thrombosis of intracranial aneurysms is uncommon. Although this type of thrombosis is largely asymptomatic, in rare cases it can be accompanied by parent artery occlusion and ischemic stroke. There are limited reports of complete thrombosis of an unruptured aneurysm of the internal carotid artery and middle cerebral artery. Furthermore, there are no reports of occlusion of the vertebral artery caused by thrombosis of an aneurysm. The mechanisms of spontaneous thrombosis are not established.

AbstractPatients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post ‐stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transfo rmation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemo...

ConclusionsThe most frequent causes of cSAH in our series were cerebral amyloid angiopathy, ischaemic stroke, and vasculitis. This type of haemorrhage has a worse prognosis than other non-aneurysmal cSAH. There are numerous possible causes, and prognosis depends on the aetiology. In elderly patients, intracranial haemorrhage is frequently associated with cognitive impairment.ResumenIntroducciónLas hemorragias subaracnoideas corticales (HSAc) tienen numerosas etiologías. No hay estudios prospectivos que indiquen su evolución a largo plazo. El objetivo de este trabajo es describir las característi...
