Miniaturized Stacked Transducer for Intravascular Sonothrombolysis With Internal-Illumination Photoacoustic Imaging Guidance and Clot Characterization
Thromboembolism in blood vessels can lead to stroke or heart attack and even sudden death unless brought under control. Sonothrombolysis enhanced by ultrasound contrast agents has shown promising outcome on effective treatment of thromboembolism. Intravascular sonothrombolysis was also reported recently with a potential for effective and safe treatment of deep thrombosis. Despite the promising treatment results, the treatment efficiency for clinical application may not be optimized due to the lack of imaging guidance and clot characterization during the thrombolysis procedure. In this paper, a miniaturized transducer was d...

Left ventricular thrombus in a patient with recurrent ischemic stroke events —The role of echocardiography
We present a patient with an ischemic stroke, and the cardiac ultrasound revealed a reduced ejection fraction and the presence of LV thrombus at the apex. The patient had no prior history of cardiovascular diseases. Even in a resource-limited setting, cardiac ultrasound is recommended to investigate stroke or transient ischemic attack events, especially in patients with a prior history of myocardial infarction. Although patients with LV thrombus should be treated with oral anticoagulants for at least 3  months, the role of direct oral anticoagulants and the optimal period of anticoagulation in this setting needs further investigation.

What Are the Classifications of Perinatal Stroke?
Discussion Perinatal stroke occurs in about 1:1000 live births and is a “focal vascular injury from the fetal period to 28 days postnatal age.” Perinatal stroke is the most common cause of hemiparetic cerebral palsy and causes other significant morbidity including cognitive deficits, learning disabilities, motor problems, sensory problems including visual and hearing disorders, epilepsy, and behavioral and psychological problems. Family members are also affected because of the potential anxiety and guilt feelings that having a child with a stroke presents, along with the care that may be needed over the child&#...

Ultrasound Criteria for Diagnosing Spontaneous Cervical Artery Dissections
This article describes the diagnostic criteria and typical findings of spontaneous dissection, in which no dissecting membrane is to be expected as in aortic dissection. Traumatic dissections following blunt or penetrating injuries also present with different findings. Examiners should be aware of possible differential diagnoses whose ultrasound image may mimic a dissection. A frequently occurring but avoidable cause of misdiagnosis is idiopathic carotidynia. Ultrasound also enables differentiation between dissection and vasculitis or carotid web and detection of normal variants such as fenestration of the vertebral artery...

In vitro study about prevention of vascular reocclusion by low intensity ultrasonic irradiation
Drug Discov Ther. 2022 Oct 9. doi: 10.5582/ddt.2022.01064. Online ahead of print.ABSTRACTFor the treatment of acute ischemic stroke, the current standard of care is thrombolysis by the administration of intravenous (IV) recombinant tissue-type plasminogen activator (rt-PA). Although this approach is proven to be effective, reocclusion within 24 hours occurs in about 20% of patients who receive recanalization by rt-PA. In addition, the administration of anticoagulants within 24 hours after IV rt-PA increases the risk of intracranial hemorrhage; therefore, treatment with anticoagulants is contraindicated in this population. ...

Detecting vulnerable carotid plaque and its component characteristics: Progress in related imaging techniques
This study compares existing clinical imaging methods, and the advantages and limitations of different imaging techniques for identifying vulnerable carotid plaque are reviewed to effectively prevent and treat cerebrovascular diseases.PMID:36188371 | PMC:PMC9515377 | DOI:10.3389/fneur.2022.982147

Point of care ultrasound detection of thrombus straddling a patent foramen ovale in a patient with acute chest syndrome
We report a case of a young woman with sickle cell disease who was hospitalized for vaso-occlusive crisis and subsequently developed worsening acute chest syndrome and stroke, discovered on point of care ultrasound to have right heart failure and a thrombus straddling a patent foramen oval. POCUS is highly specific for the detection of right heart dilation/dysfunction and should be a routine component of the assessment of acutely decompensating patients.PMID:36017251 | PMC:PMC9396226 | DOI:10.1016/j.rmcr.2022.101724

Relevance of Carotid Reocclusion in Tandem Lesions
CONCLUSIONS: CRO has a relevant clinical impact in our study, associating lower rates of good functional outcomes at 3 months. Independent factors of CRO were the recanalization degree, presence of pial collateral circulation, use of a stent as a protective factor, and use of general anesthesia during thrombectomy.PMID:35989291 | DOI:10.5551/jat.63560
