The role of contrast-enhanced ultrasound in the classification of CT-indeterminate renal lesions.

Objective: Focal renal lesions are common incidental findings on computed tomography (CT). For lesions with a cystic appearance, the Bosniak classification system has enabled an important separation of benign and (potentially) malignant cysts, giving a practical guide for management. The purpose of this study was to evaluate contrast-enhanced ultrasound (CEUS) as a problem-solving modality for classification of indeterminate renal lesions detected with CT.

[Doppler sonography of arteriovenous fistulas for haemodialysis].

Background: Permanent and reliable vascular access is of utmost importance for patients (with chronic renal failure) in need of haemodialysis. Autogenous arteriovenous fistula (AVF) on the forearm are robust and have the benefits of providing long-term access with relatively few complications. The main problem is insufficient blood flow due to stenoses requiring early intervention.

[Ultrasonography of temporal arteries in suspected temporal arteritis].

Background: In order to avoid complications in temporal arteritis, early diagnosis and start of treatment is essential. In many cases, however, the symptoms and clinical signs are non-specific. Surgical biopsy has disadvantages, and false-negative results occur.

[Treatment with percutaneous transluminal angioplasty of the popliteal and crural arteries].

Background: The role and benefit of percutaneous transluminal angioplasty (PTA) for treatment of arteriosclerotic lesions in the crural arteries has been controversial. The purpose of this study was to review our experience.

Material And Methods: 88 patients were treated with PTA for stenoses and/or occlusions of the popliteal or crural arteries.
