[Complications of subclavian and femoral cannulas]

In the course of 15 years in the author's department some 15,000 cannulas were inserted into the subclavian or femoral vein. This number included cca 2300 cannulas inserted to dialyzed patients. 213 patients (inl. 28 dialyzed) died with the inserted cannula. In these patients the incidence of complications was evaluated. A parietal thrombosis was the most frequent complication and was recorded in 119 cases, i.e. in 56% (in non-dialyzed in 57% and in dialyzed in 50%). In two non-dialyzed patients it was the cause of embolization into the lungs. In the incidence of complications there is no significant difference in dialyzed and non-dialyzed patients. For completeness the authors present a preliminary calculation per approximate number of inserted cannulas during this period. From the total number of 15,000 inserted cannulas fatal complications occurred in 0.06% (in dialyzed in 0.13% and non-dialyzed in 0.047%).
