The rapid atrial swirl sign for ultrasound-guided tip positioning of antegrade-tunneled hemodialysis catheters: A cross-sectional pilot study.

Background: We have previously reported that the rapid atrial swirl sign (RASS) is an accurate and safe procedure for ultrasound (US)-guided tip positioning of retrograde-tunneled hemodialysis catheters (HDCs). However, application of RASS for placement of antegrade HDCs has not been investigated yet. Therefore, we here report our first experience of applying RASS for US-guided tip positioning of antegrade-tunneled HDCs.

The Rapid Atrial Swirl Sign for Ultrasound-Guided Tip Positioning of Retrograde-Tunneled Hemodialysis Catheters: A Cross-Sectional Study from a Single Center.

Background: Chronic kidney disease (CKD) is a common medical problem in patients worldwide, with an increasing prevalence of patients with end-stage kidney disease (ESKD) requiring renal replacement therapy (RRT). In patients requiring RRT for more than two weeks or those who develop ESKD, tunneled hemodialysis catheter (HDC) insertion is preferred, based on a lower risk for infectious complications. While the efficacy of ultrasound (US)-guided tip positioning in antegrade-tunneled HDCs has previously been shown, its application for the insertion of retrograde-tunneled HDCs has not been described yet.

Eligibility for Baroreflex Activation Therapy and medication adherence in patients with apparently resistant hypertension.

Uncontrolled hypertension is a main risk factor for cardiovascular morbidity. Baroreflex activation therapy (BAT) is an effective therapy option addressing true resistant hypertension. We evaluated patients' eligibility for BAT in a staged assessment as well as adherence to antihypertensive drug therapy.

[The Cardiorenal Syndrome].

Chronic heart failure is associated with high morbidity and mortality and is the most common hospital diagnosis for elderly patients. Concomitant or superimposed acute or chronic kidney injury, as is the case with cardiorenal syndrome, has a dramatic impact on the outcome. The inhibition of the neurohumoral axis and the adequate treatment of hypervolemia are fundamental elements of modern cardiac insufficiency therapies.
