Anatomic variations in basilar artery termination: a systematic review and meta-analysis with presentation of an illustrative case.

PURPOSE: Despite extensive literature on anatomical variations of the basilar artery, evidence on its termination patterns is limited. We sought out to systematically pool the prevalence of basilar ar...

Migrating Needle in Right Ventricle Wall With Purulent Tamponade.

BACKGROUND Migration of foreign bodies to the right ventricle is a very rare condition, but may lead to a life-threatening state in the patient. Moreover, the presentation of symptoms in such cases ma...

Prognostic value of the TAPSE/PASP-ratio in patients with severe mitral regurgitation undergoing transcatheter edge-to-edge mitral valve repair.

BACKGROUND: Transcatheter edge-to-edge mitral valve repair (M-TEER) represents an effective treatment modality for high-grade mitral valve regurgitation. The right ventricle (RV) to pulmonary artery (...

Documented arteriovenous fistula thrill category and Doppler hemodynamics in mature radiocephalic fistulas: A single-center retrospective study.

ObjectiveTo evaluate the cross-sectional association between routinely documented arteriovenous fistula thrill categories and Doppler hemodynamic parameters in mature radiocephalic fistulas.MethodsThi...

Coats disease: A narrative review of clinical spectrum, imaging features, and contemporary management.

Coats disease is a rare idiopathic retinal vascular disorder characterized by telangiectatic and aneurysmal retinal vessels, intraretinal and subretinal lipid exudation, and variable progression to ex...

Visualization of new vessel formation during venous thrombus organization using genetic fate mapping.

BACKGROUND: Endothelial cell (EC) dysfunction contributes to venous thrombosis, and disrupting endothelial angiogenic signaling delays venous thrombus resolution. However, the time course of EC appear...

Association of Early M2 Pulsatility Index Ratio With Outcomes After Successful Endovascular Thrombectomy.

BACKGROUND AND PURPOSE: We investigated whether early transcranial Doppler (TCD) ultrasound asymmetry indices could serve as bedside predictors of hemorrhagic transformation (HT) and 90-day outcome af...

Alternating pattern formation in oscillatory media with spatially uniform and nonuniform global feedback.

Alternating (temporally period-2) stripes, clusters, and labyrinths have been observed in chemical and biochemical reactions, in Min-protein dynamics in E. coli and in vitro systems, and in calcium al...

Temporary Cement Prosthesis as a Bridge After Control of Axillary Artery Hemorrhage in Proximal Humeral Fracture-Dislocation: A Case Report.

CASE: A 64-year-old woman underwent open reduction and internal fixation for four-part proximal humeral fracture-dislocation with palpable distal pulses. Upon dislocated head removal, life-threatening...

Avoiding Iatrogenic Axillary Artery Injury in Reverse Total Shoulder for Fracture: The Use of a Separate Axillary Incision: A Case Report.

CASE: A 71-year-old woman sustained a left proximal humerus fracture dislocation. Imaging demonstrated displacement of the humeral head medial to the axillary artery without initial injury. To avoid i...

Distinct triglyceride-associated lipid profiles in coronary artery ectasia and ascending thoracic aortic aneurysm: A 10-year retrospective single-center case-control study.

ObjectiveCoronary artery ectasia (CAE) and ascending thoracic aortic aneurysm (ATAA) are vascular dilative disorders with unclear lipid profiles. We compared lipid parameters among patients with CAE, ...

Transcranial Ultrasound in the Helicopter Emergency Medical Services-A Feasibility Study.

BACKGROUND AND PURPOSE: Transcranial color-coded Doppler (TCCD) is a noninvasive, widely available diagnostic method that may identify large vessel occlusion (LVO) in acute stroke patients. This study...

Vascular dynamics in diabetic retinopathy: A systematic review and meta-analysis of ophthalmic Doppler indices in diabetic and non-diabetic populations.

BackgroundOphthalmic Doppler ultrasonography is a non-invasive technique for evaluating hemodynamic changes in diabetic patients. This meta-analysis assessed ophthalmic Doppler indices in diabetic pat...

Crossing Vessels in Retroperitoneal Laparoscopic Pyeloplasty: Anatomy and Outcomes.

PURPOSE: Crossing vessels are commonly encountered during pyeloplasty for ureteropelvic junction obstruction (UPJO) and may influence surgical strategy. We aimed to describe the anatomical distributio...

Diagnostic accuracy of zero Coronary Artery Calcium (CAC) score in a Malaysian cohort: A 20-year retrospective analysis.

INTRODUCTION: The Agatston coronary artery calcium (CAC) score is a widely used screening tool. However, its negative predictive value (NPV) in the Southeast Asian population, prone to premature non-c...

Polystyrene microplastics size as a key localization determinant for isolated adult cardiomyocytes.

There is growing evidence of the cytotoxic effects of micro- and nanoplastics (MPs) on the cardiovascular system. However, the proof of their direct interaction with living cardiomyocytes is limited. ...
