Mechanical Thrombectomy for Acute Common Carotid Artery Occlusion
Neurol Med Chir (Tokyo). 2023 Jan 5. doi: 10.2176/jns-nmc.2022-0183. Online ahead of print.ABSTRACTMechanical thrombectomy (MT) is the standard treatment for acute large occlusion of the cerebral artery. Evidence for the success of this procedure was based on the treatment of patients with internal carotid artery and middle cerebral artery thrombi. There are a few reports on thrombi extending to the common carotid artery (CCA). We document our endovascular procedure and the clinical outcome in seven consecutive patients who underwent MT for CCA thrombi between September 2016 and April 2021. Their mean National Institutes o...

Hyperacute direct thrombus imaging using CT and gold nanoparticles
Abstract Objective:Advancing the understanding and management of thromboembolic stroke requires simple and robust new methods that would be useful for the in vivo assessment of thrombus burden / distribution and for characterizing its evolution in a prompt and quantitative manner. Methods and Results:Animals (n = 127) with experimental models of thrombosis were imaged with micro‐computed‐tomography 5 min (and /or ∼ 3 weeks) after intravenous injection of glycol chitosan (GC) gold nanoparticles (AuNPs). Nanoparticles accumulated in the thrombus, allowing CT visualization of both the presence and extent of primary and ...

The Case Files: Unusual Headache
By Al-Hashimi, Siddhartha DO; Leavens, John MD A 23-year-old woman with a history of migraine headaches presented to the emergency department for a different-than-usual headache. She had a six-day history of intermittent headaches. The onset was at rest, and there was no history of trauma.   The headache was located behind her left eye, and it radiated into the posterior portion of her head. She characterized it as being 8/10 in intensity. Bright lights were reported as an exacerbating factor. The headache was associated with nausea and multiple episodes of emesis. She had 10 episodes of vomiting the evening prior to arri...

Symptomatic intracranial haemorrhage after thrombolysis with adjuvant anticoagulation in basilar artery occlusion
ConclusionsThe risk of sICH was largely determined by extension of ischaemic changes on admission computed tomography. Clinically relevantly, also higher post‐thrombolytic SBP as described earlier and lower perithrombolytic platelet counts do increase the risk, a finding requiring confirmation in other patient series.

Computed Tomography Imaging for Left Atrial Appendage Closure: A Review and Pictorial Essay
Cardioembolic stroke is an important complication of atrial fibrillation (AF). The thrombus responsible for this arises from the left atrial appendage (LAA) in>90% of cases, providing the rationale for device-based LAA closure as a means of thromboprophylaxis. While oral anticoagulant therapy remains the mainstay for reducing the risk of stroke in patients with AF, an increasing number of patients, particularly those ineligible for conventional pharmacotherapy, are being offered percutaneous left atrial appendage closure.

Calcific emboli originating from the brachiocephalic trunk causing acute cerebral infarction and worm-like calcification in the right middle cerebral artery
We report, to our knowledge, the first patient with brachiocephalic trunk calcified plaque causing the ‘salted pretzel sign’ and worm-like calcification. Arterial stenosis or occlusion caused by atherosclerosis and thrombosis are responsible for the majority of cases of cerebral infarction. However, there are a number of other causes. Interestingly, these findings were not observed on a CT scan 10days before the stroke. Acute cerebral infarction with calcifications on unenhanced head CT scans should raise suspicion for disease in the carotid system. Identification of subtle findings of acute ischemic stroke on CT scans...

Does Left Atrial Appendage Morphology Influence Left Atrial Appendage Flow Velocity?
CONCLUSIONS: The NCW-type LAA and higher BNP were associated with lower LAAFV. One reason for the frequent cardiogenic stroke in patients with the NCW-type LAA may be the lower LAAFV. PMID: 25959433 [PubMed - as supplied by publisher]

Evaluation of Cerebral Perfusion in Patients Undergoing Intravenous Recombinant Tissue Plasminogen Activator Thrombolysis.
Authors: Hirano T Abstract Currently, the indication for thrombolytic therapy using intravenous recombinant tissue plasminogen activator (rt-PA) is restricted strictly to patients with acute ischemic stroke within 4.5 h of onset. The effect of rt-PA declines over time; therefore, we need to minimize the time delay while generating imaging information. The use of cerebral blood flow imaging is not recommended within this time window. Conversely, the balance of efficacy and the risk of bleeding complications differ among patients > 4.5 h after onset. Several ongoing studies are using mismatch concepts to extend th...

A Case Report of Locked-in Syndrome Due to Bilateral Vertebral Artery Dissection After Cervical Spine Manipulation Treated by Arterial Embolectomy
Abstract: Cervical spine manipulation (CSM) is a commonly spinal manipulative therapies for the relief of cervical spine-related conditions worldwide, but its use remains controversial. CSM may carry the potential for serious neurovascular complications, primarily due to vertebral artery dissection (VAD) and subsequent vertebrobasilar stroke. Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy. A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour. Gradually, alt...
