INTRODUCTION: Oral anticoagulant therapy, such as vitamin K antagonists (VKAs), is prominent for the prevention of cerebral ischemic stroke or systemic embolism and all-cause mortality in patients with atrial fibrillation, venous thromboembolism, and mechanical or biological valve. VKA treatment requires monitoring of the international normalized ratio (INR) in order to maintain it in a therapeutic range, avoiding side effects, the main and most significant of which is bleeding. The aim of the present study was to evaluate the event rates of several clinical composite outcomes, such as bleeding, thromboembolic events, and all-cause death...

BACKGROUND: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...

Upon detection of foreign-body embolization to the central nervous system (CNS) following a specific invasive cardiovascular procedure in 1 autopsied child, we undertook a quality assurance analysis to determine whether other patients had had similar events. Autopsies of all infants and children with history of cardiac catheterization, heart surgery on cardiopulmonary bypass, and/or extracorporeal membrane oxygenation over a 5-year period at a single tertiary care institution were reviewed for light-microscopic evidence of foreign material...

CASE: A 44-year-old man intentionally stabbed himself in the anterior neck and left thorax with a fruit knife. Physical examination revealed two open wounds entering the thoracic cavity in the front chest, and a stab wound entering the trachea at the neck. Two chest tubes were initially inserted for the left lung injury with open hemopneumothorax. Nevertheless, the worsening oxygenation required positive pressure ventilation (PPV) with endotracheal intubation. OUTCOME: Right hemiparesis was found during weaning from PPV...

The clinical manifestations of vertebral artery (VA) injury (VAI) after cervical trauma range from asymptomatic to fatal cerebral infarction. Thrombotic occlusion and embolization to the distal arteries can cause cerebellar and brain stem infarction within days after trauma. We report a 64-year-old man who underwent arthrodesis surgery for C1 and C2 fractures. He had left VAI at the C2 transverse foramen site but was asymptomatic. The patient experiences brainstem and cerebellar infarction 3 months after injury to the VA, and we are here to discuss the treatment of VAI after cervical trauma...

BACKGROUND: Preoperative embolization is established as an advantageous adjunct in multimodality treatment of cerebral arteriovenous malformations(AVMs). However, the benefit of preoperative embolization in AVMs with favorable surgical risk profile is debatable, as it has yet to be supported by evidence in comparative studies. In this study, we assessed outcome of surgically-treated patients in a comparative setting. METHODS: Our institutional AVM database of retrospectively and prospectively collected data between 1990-2015 was reviewed...

: Atrial fibrillation is the most common arrhythmia in over-midlife patients. In addition to systolic heart failure, cerebral thromboembolism represents the most dramatic complication of this rhythm disorder, contributing to morbidity and mortality. Traditionally, anticoagulation has been considered the main strategy in preventing stroke and systemic embolism in atrial fibrillation patients and vitamin K-dependent antagonists have been widely used in clinical practice. Recently, the development of direct oral anticoagulants has certainly improved the management of this disease, providing, for the first time, the opportunity to go beyond vitamin K-dependent antagonists limits...

Surgical resection is the current standard of therapy for the treatment of arteriovenous malformation (AVM). Endovascular embolization is commonly used as an adjunct prior to surgical resection because it is believed to reduce the risk of intraoperative bleeding. Embolization has been associated with other complications including visual deficits, vessel perforation, and catheter adhesion. Catheter adhesion in which retained segments are contained within the embolization cast are not necessarily cause for concern, but retention of larger portions may confer an increased risk of thrombus formation...

An 8-month old female presented with spontaneous subarachnoid hemorrhage and was treated successfully with endovascular coil embolization of the ruptured aneurysm. Transcranial Doppler ultrasound performed four days later demonstrated middle cerebral artery (MCA) velocities greater than 350 cm/sec on the right and greater than 200 cm/sec on the left, despite medical management. The patient demonstrated no focal neurological deficits, though examination was limited by our patient's sedation and intubation. Angiography revealed severe vasospasm of the supraclinoid internal carotid and MCA territories, bilaterally...

A giant intracranial internal carotid artery(ICA)aneurysm is difficult to treat. We encountered a case with an unruptured giant intracranial ICA aneurysm with a ruptured C2 aneurysm of the ipsilateral ICA. In this case report, we describe how the treatment and review the literature. A 59-year-old man presented with sudden-onset headache and vomiting. He was diagnosed at a local neurosurgical unit as having a subarachnoid hemorrhage and admitted to our hospital. Cerebral angiogram revealed an unruptured giant ICA C3-4 aneurysm with a ruptured aneurysm of the ipsilateral ICA C2...

Duplication of the middle cerebral artery(MCA)is an anatomical variant of the MCA, originating from the distal portion of the internal carotid artery(ICA)and supplying blood flow to the tip of the temporal lobe. Cerebral aneurysms rarely develop at the bifurcation of the ICA and the duplicated MCA, but when they do develop, they may result in subarachnoid hemorrhage. We treated a 41-year-old man, who was urgently brought to our hospital because of severe headache. A computed tomography(CT)scan showed subarachnoid hemorrhage due to the rupture of an aneurysm at the origin of the duplicated MCA...

BACKGROUND AND PURPOSE: While the majority of cerebral ischemic events due to carotid occlusive disease result from atherosclerotic plaque rupture, intraluminal carotid artery thrombus occasionally occurs in patients without preexisting carotid atherosclerosis. Identification of nonatherosclerotic thrombus as the cause of the carotid occlusive disease can obviate the need for an interventional procedure, and resolution of thrombus can be monitored with B-mode duplex ultrasonography. METHODS: We reviewed 3 patients treated on The Mount Sinai Hospital Stroke Unit with anticoagulation for nonatherosclerotic carotid thrombi and followed with serial Doppler ultrasonogrpahy for resolution of thrombus...

BACKGROUND: Some intracranial aneurysms treated by stent-assisted coiling (SAC) with incomplete occlusion undergo progressive occlusion (PO) during follow-up period. We analyzed the predictors for the occurrence of PO. METHODS: Among 74 cerebral aneurysms treated by SAC using the Enterprise or Neuroform stents from 2010 to 2015, we included 43 aneurysms with occlusion grade of neck remnant (NR, n = 36) or residual aneurysm (RA, n = 7) at the post-procedure. We defined PO as improvement in occlusion grade from RA to NR, or from NR or RA to complete occlusion on angiographic follow-up imaging at 6 months after the procedure...

BACKGROUND AND PURPOSE: Flow diversion is a relatively new strategy used to treat complex cerebral aneurysms. The optimal method for radiographic follow-up of patients treated with flow diverters has not been established. The rate and clinical implications of in-stent stenosis for these devices is unclear. We evaluate the use of transcranial Doppler ultrasound (TCD) for follow-up of in-stent stenosis. MATERIALS AND METHODS: We analyzed 28 patients treated with the Pipeline embolization device (PED) over the course of 42 months from January 2009 to June 2012...

BACKGROUND: Cardiac myxoma is known to cause repeated events of cerebral embolism. Soft and irregularly shaped myxomas with high mobility are associated with a higher occurrence of cerebral embolism. In contrast, nonmobile cardiac myxomas with a round regular shape are rarely considered to be a cause of cerebral embolism. In this case, we present a patient with recurrent cerebral embolism associated with a small and nonmobile cardiac myxoma of round regular shape.

: Transesophageal echocardiography is frequently performed for further evaluation of sources of embolism and better evaluation of atrial septum in patients with cerebral ishemic events. Although two-dimensional transesophageal echocardiography can depict atrial septal aneurysm and patent foramen ovale, the full extent of the patent foramen ovale cannot be easily discerned in some cases. We describe a patient with transient cerebral ischemia where three-dimensional echocardiography provided incremental value when compared to two-dimensional transesophageal echocardiography in the assessment of atrial septal aneurysm and patent foramen ovale...

Postoperative visual loss is an extremely rare complication of nonocular surgery. The most common causes are ischemic optic neuropathy, central retinal artery occlusion, and cerebral ischemia. Acute visual loss after spinal surgery is even rarer. The most important risk factors are long-lasting operations, massive bleedings, fluid overload, hypotension, hypothermia, coagulation disorders, direct trauma, embolism, long-term external ocular pressure, and anemia. Here, we present a case of a 54-year-old male who developed acute visual loss in his left eye after a lumbar instrumentation surgery and was diagnosed with retinal artery occlusion...

BACKGROUND Given the recent completion of multiple trials demonstrating the benefit of endovascular mechanical thrombectomy for select patients with proximal large artery occlusive ischemic strokes, there has been a large increase in the performance of these procedures. In the context of increased thrombectomy performance, there have also been increased reports of rare occurrences of granulomatous inflammatory response to the hydrophilic polymer which coat many of these interventional devices.
