Journal of clinical apheresis

Many vascular access options, such as subcutaneous ports, are currently on the market for use in both medication infusion and for procedures, such as therapeutic plasma exchange and extracorporeal photopheresis. We compared the cost and time necessary to complete apheresis procedures using either Angiodynamic's Vortex or Bard's PowerFlow subcutaneous ports by reviewing our experience on two patients undergoing long-term apheresis treatments with at least 10 procedures with each type of port. ⋯ In this small pilot study, use of the PowerFlow port resulted in significant cost and time savings, with mixed results for flow rates. Our results need to be confirmed in a larger patient population prior to recommending wide implementation of Bard's PowerFlow port.

Comparative Study Clinical Trial
Mononuclear cell collection for extracorporeal photopheresis by using the "off-line" system: A comparative study between COBE Spectra and Spectra Optia devices.
Extracorporeal photopheresis (ECP) is an efficient and established therapy to treat acute and chronic graft vs host disease (GVHD). Using an "off-line" method, the first step (mononuclear cell [MNC] collection) is decisive, as long as a high MNC yield and purity in the collected product is desirable. Two "off-line" devices were compared: the COBE Spectra and the Spectra Optia (Terumo BCT), using both continuous and intermittent protocols. ⋯ In our study, Spectra Optia proved to be safe and effective in collecting MNC with high yield and purity for ECP in GvHD.
