Transvenous serial xero-arteriography: a new non-invasive angiographic method for AV-fistulas in haemodialysis patients.

A new technique--transvenous serial Xero-arteriography (TSXA)--was evaluated in order to avoid the risks of the commonly used angiographic methods in av-fistulas. The contrast medium is injected intravenously in the contralateral forearm, an average of 5 per cent of the total contrast medium appearing in the arm to be examined. The Xerox-system now allows visualisation of both arteries and fistulated veins. Using a cassette-changer morphologic and functional alterations can be examined. TSXA is largely free of risk, avoiding arterial access and patient discomfort. TSXA gives reliable information about the real haemodynamic situation of av-fistulas including morphologic and functional alterations. Thus, surgical procedures can be performed more precisely, more carefully and time-saving.

[Cystic pseudotumors (baker cysts) of the popliteal fossa (author's transl)].

Report on 38 Baker cysts found in 300 knee arthrographies performed for clinically suspected meniscus lesions. In order not to miss these cysts, fluoroscopy and/or X-ray documentation immediately following the instillation of contrast material and air into the knee joint is mandatory, because these contrast agents tend to disappear fairly rapidly, leaving the lesion poorly visible towards the end of the examination. Furthermore, the clinical significance and the therapeutic aspects of Baker cysts are discussed.

[Localized interstitial calcinosis (author's transl)].

Case report of an unusual case of soft tissue calcification in the lower leg of a 50 year old patient examined for compensation problems for a gunshot fracture suffered in World War II. The differential diagnosis "localized interstitial calcinosis", "myositis ossificans" and "myositis ossificans progressiva" is being discussed.
