Abstract
The central venous catheter (CVC) is considered the most reliable type of temporary blood access, and longer-term blood purification has become possible with its improvement. We report the clinical evaluation of a new CVC, the Tornado catheter, and discuss complications associated with the long-term use of the CVC (L-CVC). We placed Tornado catheters in the internal jugular vein for 1–2 weeks in 10 patients. L-CVC were employed in 14 patients undergoing maintenance hemodialysis (HD). In only 2 of 10 patients with a Tornado catheter, the blood flow was decreased during HD due to clot formation on the arterial side. No patients had other complications. In patients with L-CVC, poor blood flow often occurred. In two patients with cardiac dysfunction, we have been using CVC for more than 12 months. The development of a CVC that will serve as a permanent blood access is expected.
