Ischemic stroke after pellet embolization
A 9-year-old boy was shot with a pellet shotgun and developed a visual field deficit. Head CT revealed a pellet in the left ambien cistern, in the left posterior cerebral artery on catheter angiography (figure). Chest fluoroscopy revealed multiple thoracic pellets, including a mobile cardiac pellet (video on the Neurology® Web site at Neurology.org). There was no clear cardiac injury, patent foramen ovale, or skull penetration. Arterial embolization of a pellet from the chest to the intracranial vasculature likely caused a stroke.1,2 We considered arteriotomy, endovascular retrieval, and medical therapy. The establishe...

Propensity Score-Matched Analysis of Lesion Patterns in Stroke Patients With Patent Foramen Ovale and Patients With Spontaneous Intracranial Artery Dissection
Conclusion: The present study suggests that lesion patterns observed from DWI of patients with PFO and SIAD might provide clues to the etiology of infarcts. Single lesions (cortical or subcortical) might be a typical feature of PFO associated strokes, while multiple lesions in one vascular territory might be a specific feature of SIAD associated strokes. Introduction Both patent foramen ovale (PFO) and spontaneous intracranial artery dissection (SIAD) are important stroke risk factors, especially in young and middle-aged adults (1–3). About 25% of patients with ischemic stroke are cryptogenic (4), and PFO is ...

Imaging Characteristics of Ischemic Strokes Related to Patent Foramen Ovale Clinical Sciences
Conclusions— A PFO-stroke usually appears as a single cortical or multiple small ischemic lesions in the vertebrobasilar circulation without any visible vessel occlusion on angiography. The recanalization rate is significantly lower than in AF-stroke. These imaging characteristics of PFO-stroke may help to diagnose the mechanism and determine the treatment strategy.

A Case of Multiple Recurrent Ischemic Stroke in a Patient with Cholangiocarcinoma and Initiation of Anticoagulation Therapy for Secondary Stroke Prevention (P4.342)
CONCLUSIONS: Initiation of anticoagulation therapy and the optimal medications for secondary stroke prevention in cancer associated stroke remain controversial. Further randomized prospective studies are needed to establish treatment guidelines.Disclosure: Dr. Cheng has nothing to disclose. Dr. Then has nothing to disclose.

Diagnostic Yield of Venous Thrombosis and Pulmonary Embolism by Combined CT Venography and Pulmonary Angiography in Patients with Cryptogenic Stroke and Patent Foramen Ovale
Background: Paradoxical embolism via a patent foramen ovale (PFO) has been suggested as a potential stroke mechanism. Combined CT venography and pulmonary angiography (CVPA) is a simple, validated and accurate technique to diagnose deep venous thrombosis (DVT) or pulmonary embolism (PE). We sought to assess the prevalence of DVT or PE among patients with PFO and cryptogenic stroke (CS) by CVPA. Methods: Patients were identified retrospectively from a clinical registry of consecutive patients with stroke admitted to our Stroke Unit. The following criteria were required for inclusion in this study: CS, PFO identified by tran...

Advances in stroke medicine.
Authors: Campbell BC Abstract In recent years, reperfusion therapies such as intravenous thrombolysis and endovascular thrombectomy for ischaemic stroke have dramatically reduced disability and revolutionised stroke management. Thrombolysis with alteplase is effective when administered to patients with potentially disabling stroke, who are not at high risk of bleeding, within 4.5 hours of the time the patient was last known to be well. Emerging evidence suggests that other thrombolytics such as tenecteplase may be even more effective. Treatment may be possible beyond 4.5 hours in patients selected using brain imagi...

Value of Eye Movement Exam in Aiding Precise Localization in Stroke (P1.016)
We present an unusual presentation of midbrain stroke presenting with bilateral ptosis in an African American male with vascular risk factors and concurrent use of bevacizumab. This case illustrates how detailed knowledge of anatomy and detailed neurologic exam remain valuable tools for localizing and diagnosing subtle presentations of common neurologic disease. Case description: A 69 year-old African American man with vascular risk factors including hypertension, hyperlipidemia and poorly controlled diabetes experienced sudden onset horizontal diplopia associated with fatigue. The patient presented to the Emergency Depart...

Advanced imaging in acute ischemic stroke.
Abstract The evaluation and management of acute ischemic stroke has primarily relied on the use of conventional CT and MRI techniques as well as lumen imaging sequences such as CT angiography (CTA) and MR angiography (MRA). Several newer or less-established imaging modalities, including vessel wall MRI, transcranial Doppler ultrasonography, and 4D CTA and MRA, are being developed to complement conventional CT and MRI techniques. Vessel wall MRI provides high-resolution analysis of both extracranial and intracranial vasculature to help identify previously occult lesions or characteristics of lesions that may porten...

Pulmonary Embolism in Ischemic Stroke.
Abstract Silent pulmonary embolism (PE) may be associated with acute ischemic stroke (AIS). We identified 10 patients from 3,132 unique patients (3,431 CT scans). We retrospectively examined CT angiogram of patients with AIS to determine the frequency of concurrent PE in AIS. The period prevalence of PE was 0.32. Seven patients had concurrent PE, whereas three had PE diagnosed 2 days after their AIS presentation. We suspected paradoxical embolism via patent foramen ovale as the cause of stroke in three patients and thrombophilia in four patients. Seven patients had poor outcome including four deaths. CT angiogram ...

Coronary Artery Disease in Adults Undergoing Percutaneous Patent Foramen Ovale Closure Following Cryptogenic Stroke
CONCLUSIONS: Coronary angiography identified a low prevalence of CAD in patients with cryptogenic stroke undergoing PFO closure, suggesting that coronary angiography is not routinely indicated in patients undergoing PFO closure.PMID:34653956
