Katheterinduzierte Thrombosen - duplexsonographische Untersuchungen zu Häufigkeit und Ausmaß

Abstract

The aim of the study was to detect the frequency and the extension of thrombosis caused by central venous catheters by means of Doppler-duplex ultrasound. 36 patients were examined. The visualization rate of catheters in jugular (91%) and femoral (62%) veins was excellent. In contrast, catheters in the subclavian vein could be detected only in 33 per cent of all cases. As a result the overall patency rate of catheters was only 37 per cent after a period between 8 hours and 60 days (12.2 +/- 11.3 days) following the introduction. There was no significant relation between the type of catheter, the management with central venous catheters and the rate of thrombosis.
