Doppler sonographic evaluation of venogenic extremity swellings: Analysis of 170 patients from Kano, Nigeria
Conclusion: There was a predominance of females and femoro-popliteal segments in DVT. Doppler ultrasound is very useful in the evaluation of extremity DVT. All clinically suspected cases should be evaluated with this modality due to limited sensitivity of clinical evaluation in the diagnosis of DVT. Further correlative studies in comparison to venography and hematologic indices are also recommended.

Clinical outcomes of state-of-the-art percutaneous coronary revascularization in patients with de novo three vessel disease: 1-year results of the SYNTAX II study
ConclusionAt one year, clinical outcomes with the SYNTAX-II strategy were associated with improved clinical results compared to the PCI performed in comparable patients from the original SYNTAX-I trial. Longer term follow-up is awaited and a randomized clinical trial with contemporary CABG is warranted.ClinicalTrials.gov IdentifierNCT02015832

Inertial cavitation effect of catheter- based Q-switched ND:YAG laser enhance extracorporeal pulsed- focused ultrasound thrombolysis
Aim: A plaque may rupture with high risk of subsequent thrombus- mediated acute clinical events such as myocardial infarction and stroke. Catheter-based lasers have been extensively studied as an effective method to treat thrombosis. Focused ultrasound is one of the non- invasive methods to treat abnormal tissues. In pulsed- focused ultrasound with low duty cycle, which is used for thrombolysis, energy deposition rates are low enough that temperature rises are well below the threshold for thermal damage.

Sonographic and Doppler Sonographic Diagnosis of  Neonatal Ischemic Stroke.
Sonographic and Doppler Sonographic Diagnosis of Neonatal Ischemic Stroke. Ultraschall Med. 2017 Jul 13;: Authors: Deeg KH Abstract Children are particularly at risk for stroke in the neonatal period. 1/3 of all strokes in children occur during the perinatal period. The incidence of perinatal stroke is 1:4000. A differentiation is made between ischemic stroke and hemorrhagic stroke. Ischemic strokes are caused by arterial occlusion due to thrombosis or embolism. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom...

The Thrombolytic Effect of Diagnostic Ultrasound–Induced Microbubble Cavitation in Acute Carotid Thromboembolism
Conclusions: High MI 20-microsecond pulse duration impulses during a commercial microbubble infusion can be used to recanalize acutely thrombosed carotid arteries and restore downstream flow without anticoagulants. However, this effect is only seen with SC-inducing impulses and not at higher mechanical indices, when a paradoxical reversal of the thrombolytic effect is observed. Diagnostic ultrasound–induced SC can be a nonsurgical method of dissolving CA thrombi and preventing thromboembolization.

Ischemic stroke in a patient with Parry-Romberg syndrome (P4.064)
Conclusions:The only other reported patient with PRS and stroke was also found to have a PFO. It is possible that the elevated ANA seen in this patient correlates with propensity towards small venous clots not seen on ultrasound. This may lead to paradoxical emboli and ischemic strokes. It is important to note this potential association between PRS and ischemic stroke in young patients without other known risk factors. It would be worthwhile to treat this subset of patients with medications for secondary stroke prevention.Disclosure: Dr. Ebiana has nothing to disclose. Dr. Singh has nothing to disclose.

Emergent Endovascular Management of Long-Segment and Flow-Limiting Carotid Artery Dissections in Acute Ischemic Stroke Intervention with Multiple Tandem Stents EXTRACRANIAL VASCULAR
CONCLUSIONS: Emergent stent reconstruction of long-segment and flow-limiting carotid dissections in acute ischemic stroke intervention is safe and effective, with favorable clinical outcomes, allowing successful thrombectomy, vessel salvage, restoration of cerebral perfusion, and/or prevention of recurrent thromboembolic stroke.

Crucial role of carotid ultrasound for the rapid diagnosis of hyperacute aortic dissection complicated by cerebral infarction: A case report and literature review.
Abstract Aortic dissection is a life-threatening rare condition that may virtually present by any organ system dysfunction, the nervous system included. Acute cerebral infarction among multiple other neurological and non-neurological presentations is part of this acute aortic syndrome. Rapid and correct diagnosis is of extreme importance keeping in mind the possibility of thrombolytic treatment if a patient with a suspected ischemic stroke arrives to the Emergency Department within a 4.5-h window after symptom onset. Systemic intravenous thrombolysis in the case of an acute brain infarction due to aortic dissectio...

Association of Subjective and Objective Sleep Duration as well as Sleep Quality with Non-Invasive Markers of Sub-Clinical Cardiovascular Disease (CVD): A Systematic Review.
CONCLUSIONS: Overall, our review provided mixed results, which is generally in line with published literature, with most of the studies showing a significant relationship with subclinical CVD, but only some studies failed to demonstrate such an association. Although such mechanistic relationship needs further evaluation in order to determine appropriate screening strategies in vulnerable populations, this review strongly suggested the existence of a relationship between abnormal sleep duration and quality with increased subclinical CVD burden.

Fifty years of brain imaging in neonatal encephalopathy following perinatal asphyxia.
Abstract In the past brain imaging of term infants with hypoxic-ischemic encephalopathy (HIE) was performed with cranial ultrasound (cUS) and computed tomography (CT). Both techniques have several disadvantages sensitivity and specificity is limited compared with magnetic resonance imaging (MRI) and CT makes use of radiation. At present MRI including diffusion weighted MRI during the first week of life, has become the method of choice for imaging infants with HIE. In addition to imaging, blood vessels and blood flow can be visualized using MR angiography, MR venography, and arterial spin labeling. Since the use of...

Elevated serum homocysteine level as an independent risk factor for erectile dysfunction: a prospective pilot case –control study
Summary Homocysteine is an amino acid that is produced from the metabolic demethylation of dietary methionine. It has gained arising attention for its association with increased risk of myocardial infarction, stroke and venous thromboembolism. Erectile dysfunction (ED), especially for vasculogenic ED, is a vascular disorder of cavernosal vascular bed. In this prospective pilot case–control study, we investigated plasma homocysteine levels in 32 ED patients and 20 healthy control men. Related patients characteristics including age, weight, height, marital status, smoking and drinking status, level of education were collec...

The Enhancing Effect of Focused Ultrasound on TNK-Tissue Plasminogen Activator-Induced Thrombolysis Using an In Vitro Circulating Flow Model
The limited efficacy of thrombolytic therapy in patients with ischemic stroke has created the need to use focused ultrasound (FUS) energy as a way to enhance thrombolysis efficacy (sonothrombolysis). Using an in vitro circulating flow model, we evaluated the role of physical parameters on tenecteplase (TNK-tPA)-mediated thrombolysis.
