RESUMO
Objective To advocate the importance of central venous access(CVA), and compare the technical characteristics and clinical values of central venous access constructed trans right subclavian vein (TSCV) and trans the right internal jugular vein (TIJV). Methods Between March 1999 and June 2001, we operated 348 cases of CVA, including 270 TSCV and 78 TIJV. The durations of reserving the accesses were 13～75 day, average 23 days. Results In 270 TSCV, 268 cases were successful, the successful rate was 99%. 11 cases had critical complications, including: 2 cases of pneumothorax, 1 access was constructed into subclavian artery, 3 accesses obstruction, 3 accesses of anomalous transfusion caused by catheter shift, infection of puncture site 2 cases. In 78 TIJV, 75 cases were successful, the successful rate were 96%. The critical complications occurred in 1 case.Conclusions The CVA is safe, easy, and practical, which would provide the special and immediate medical therapy for the tumorous and critical patients. In emergency, the TSCV procedure would be the choice.
