Background: The risk for contrast-induced nephropathy (CIN) after intra-arterial application of an iodine-based contrast material is unknown for patients with chronic kidney disease (CKD) and peripheral arterial disease (PAD).
Purpose: To investigate the incidence of CIN in patients with CKD and PAD.
Material And Methods: This retrospective study was approved by the local ethics committee.
Objective: To prospectively evaluate the clinical benefit of a central venous port system, which is approved for contrast media injection during contrast enhanced computed tomography.
Materials And Methods: At a university teaching hospital, 98 patients (59 female, 39 male; median age 61.7 years; range 23-83) had a power-injectable central venous port catheter system implanted.
Purpose: A prospective, randomized-controlled trail was conducted to evaluate the effectiveness of securing tunneled hemodialysis (HD) catheters with sutureless StatLock attachment devices (Bard Access Systems) compared to traditional suture fixation.
Methods: At a university teaching hospital 72 patients with chronic renal failure received cuffed tunneled HD catheters. In the study group (n=36) the HD catheters were secured with a sutureless StatLock attachment device, whereas the control group HD catheters were fixated with sutures only.
Objectives: We evaluated the precision of multislice spiral computed tomography (MSCT) for the quantification of aortic valve stenosis in comparison with echocardiography and cardiac catheterization.
Materials And Methods: An electrocardiogram-gated MSCT scan (detector collimation 40 x 6.25 mm, gantry rotation time 420 milliseconds, pitch 0.
