Sonographic Venous Velocity Index Identifies Patients with Chronic Kidney Disease and Severe Diastolic Dysfunction 

Markus Meier et al.

DOI: 10.1055/a-0684-9483

Diagnosing cardiorenal syndrome (CRS) in patients with chronic kidney disease (CKD) continues to remain challenging in outpatient practice. In this study, the authors investigate whether a newly developed venous velocity ultrasound index (VVI) can differentiate between patients with CRS and patients with CKD of other cause or normal renal function (NRF).

Fig. 1 Exemplary kidney duplex ultrasound investigations of a patient with CKD. Venous Doppler spectrum of a patient with ADPKD a shows a monophasic negative flow pattern, whereas a patient with nephrosclerosis shows a biphasic flow pattern b. Calculation of the venous duplex index (VVI) in patient A (no positive flow): VVI = 0; patient B: VVI = V1 / V2 = 0.16.

Phantom Nodules Detected by Ultrasound Examination of the Neck: The Possibility of Ectopic Cervical Thymic Tissue in Adults

The aim of this study was to investigate the ultrasound characteristics and clinical significance of slightly hyperechoic lesions, referred to as phantom nodules, in the perithyroidal area in patients.

Sonographic Evaluation of Nodules Newly Detected in the Neck After Thyroidectomy: Suture Granuloma Versus Recurrent Carcinoma 

Hitomi Aga et al.

DOI: 10.1055/a-0749-8688

The team of authors retrospectively analyzed ultrasound reports with images of 25 cases of suture granuloma and 18 cases of recurrent carcinoma that newly appeared in the resected area after thyroidectomy in their institution.
