[Flow obstruction and infection associated with the two-lumen subclavian catheter].
BACKGROUND
The aim of this study was estimate correlation between catheter clotting and catheter-related injection in haemodialysis (HD) patients with temporary double lumen catheters (TDLC).


METHODS
We analysed 128 TDLC where we had exact microbiological result from catheter tip. There were 107 patients, mean age 54.70 +/- 15.02 years (15.80); 52 (48.60%) male ad 55 (51.40%) female, which were on haemodialysis 1162.62 +/- 183,424 (6-7200) days.


RESULTS
Major reasons for application TDLC were acute HD in 56 (43.75%), a function of A-V fistula in 40 (31.25%) patients, and a function of previous TDLC in 32 (25%) patients. The primary causes of chronic renal disease were diabetes mellitus in 34 (27%), pyelonephritis in 31 (24%), glomerulonephritis in 24 (19%), polycistic kidney disease in 14 (11%), nephropathia endemic in 10 (8%) and others disease in 15 (12%) of patients. The analysed TDLC remained in place for an average of 51.34 +/- 64.03 (range 2-518) days. In case of 92 (71.88%) we got positive microbiological result (Staphylococcus coagulasa negative 33%, Staphylococcus aureus 16%, Bacillus species 9%). In 38 of these catheters (41.30%) we diagnosed problems with blood flow. Totally, we had 50 TDLC with obstruction, but in 12 of them we did not have microbiological confirmation of infection.


CONCLUSIONS
Catheter clotting is one of the important factors that increase risk for developing catheter-related infection.
