Treatment of Acute Stroke: Current Practices and Future Horizons.

Purpose: This review will discuss revascularization of acute ischemic stroke (AIS), discussing the concept of the ischemic penumbra and how thrombolysis and thrombectomy take advantage of it.

Summary: The goal of AIS revascularization is to rescue the ischemic penumbra and the approach to has gone from a time-based to tissue-based approach. Patients must be carefully selected for thrombolysis, which traditionally was limited to those whose last known normal time (LKNT) was known and within 4.

Giant Vertebrobasilar Aneurysm: The Rule of Decompressive Craniectomy Previous to Endovascular Treatment.

Giant vertebral-basilar aneurysms are rare and represent 1% of intracranial aneurysms. Natural history and treatment are associated with severe clinical manifestations, such as ischemia, mass effect, hydrocephalus, and subarachnoid hemorrhage, leading to high mortality and morbidity. In this case, a 51-year-old male with no relevant medical history presented to the emergency department with severe pulsatile right temporo-occipital headache, radiating to the territory of the maxillary branch of the trigeminal nerve.

Materials And Methods: Herein, we report a young adult patient with acute ischemic stroke treated with repeated mechanical thrombectomy for recurrent large vessel occlusions caused by left ventricular thrombus following a silent myocardial infarction.

Stent retriever thrombectomy in the treatment of basal artery stent thrombosis: Two case reports.

Rationale: Stent thrombosis is a rare but serious complication that requires timely treatment. Catheter thrombectomy is the first-line therapy for this condition; however, it may be challenging for patients with in-stent emboli located in the basilar artery.

Patient Concerns: Herein, we reported 2 cases with stent thrombosis in the vertebrobasilar artery, including their imaging and clinical findings.

An Institutional Experience and Literature Review on Iatrogenic Major Vascular Injury in Neurosurgery: Proposal of a Management Algorithm.

Background: Major vessel injury is among the most dreaded complications of any neurosurgical procedure. Once intraoperatively tamponaded, it can present in the form of pseudoaneurysm, dissecting aneurysm or complete occlusion of vessel. These injuries are often associated with very high morbidity and mortality.

CT Marker in Emergency Imaging of Acute Basilar Artery Occlusion: Thrombosis vs. Embolism.

Purpose: Acute basilar artery occlusion, a neurovascular emergency leading to high rates of morbidity and mortality, is usually diagnosed by CT imaging. The outcome is partly dependent on etiology, with a worse outcome in occlusions with underlying basilar artery stenosis. As this occlusion type requires a more complex angiographic therapy, this study aimed to develop new CT markers in emergency admission imaging to rapidly identify underlying stenosis.

Stand-Alone Large Bore Aspiration Catheter (0.072 Inch) for Both Guide Support and Clot Aspiration in Transradial Posterior Circulation Stroke Thrombectomy: Technical Series.

Background: The large size of guide catheters in the traditional triaxial configuration can prove limiting during transradial vertebrobasilar thrombectomy. This is especially important for the direct aspiration technique because of the large aspiration catheters that can reach an inner diameter of 0.072 in.

Endovascular thrombectomy using a stent retriever catheter for massive pulmonary thromboembolism.

Acute massive pulmonary thromboembolism (PE) has a high mortality rate of 18%-65%. Along with anticoagulation and thrombolytic therapy, treatment may require a catheter-based thrombectomy or surgical thrombectomy. We report a case of pulmonary thromboembolism treated with a Stent Retriever (Trevo® NXT ProVue Retriever, Stryker, Kalamazoo, MI, USA), which is commonly used to treat stroke.

Arterial Thrombosis of Unknown Etiology in a 10-Year-Old Male.

Arterial thrombotic events are exceedingly rare occurrences in pediatric populations. The incidence of childhood thrombosis is extremely low and the majority of cases are venous in origin. There are several well-known etiologies and genetic risk factors with an underlying predisposition to venous thrombosis, however, there have been few identified etiologies of arterial thrombotic events in pediatric patients.

Unsuccessful bypass and trapping of a giant dolichoectatic thrombotic basilar trunk aneurysm. What went wrong?

Aneurysms of the basilar trunk represent an exceptional challenge to the neurosurgeon, due to high mortality and surgical morbidity. We present a 69-year-old man with a giant dolichoectatic thrombotic basilar trunk aneurysm (BTA), who underwent right orbitozygomatic craniotomy, posterior cerebral artery (PCA) to right middle cerebral artery (MCA) bypass and trapping of the BTA. Unfortunately, patient died after surgery due to multiple foci of intraparenchymal haemorrhage and thrombosis of a short segment proximal to aneurysm trapped and his body was donated to the hospital, giving us the unique opportunity to compare intraoperative details with anatomical dissection findings, according to our previously published cadaveric neurosurgical research.

Transient Ischemic Attack Due to Unruptured Basilar Artery Aneurysm.

Intracranial aneurysms are typically asymptomatic. They are usually incidentally detected or detected only after rupture. Ischemic stroke or transient ischemic attack (TIA) due to unruptured intracranial aneurysms (UIAs) is rare.

Antiplatelets and Anticoagulants in Ischemic Stroke,Transient Ischaemic Attack: A Practice Survey Among Singapore Neurologists.

Purpose: Evidence-based stroke clinical practice guidelines provide guidance as how to best manage patients with cerebrovascular disease. Where there are grey zones, the clinician decides what she/he feels is the most appropriate in that circumstance. This study was performed to determine how adult neurologists in Singapore would use antiplatelets(AP) and anticoagulants(AC) for their ischemic stroke patients in various settings where the evidence is uncertain.

Dolichoectasia: a brain arterial disease with an elusive treatment.

Introduction: Dolichoectasia is a form of brain large artery disease associated with a high risk of mortality and morbidity. Progressive enlargement of arterial size is a predictor of mortality, but there are no specific treatments for arresting or slowing down dilatation. Additionally, dilated brain arteries can cause flow stagnation, which can trigger thrombosis and cause stroke.
