Purpose: To describe a novel configuration of venous access for the performance of intermittent apheresis. Participants: 20 participants at UNC who were referred for change from a vortex port to a powerflow port. Procedures (methods): Placement of one of two configurations of the powerflow port and follow up visits between January 1, 2019 and December 31, 2023.
Study Type
OBSERVATIONAL
Enrollment
20
The study will compare pheresis sessions with the old system versus pheresis sessions with one of two new configurations.

Change in Flow Rate
The study will compare mean change flow rate for pheresis sessions with the old system versus pheresis sessions with one of two new configurations by averaging the flow rate for up to 5 sessions using the new port configuration.
Time frame: 1 year following new port configuration placement
Change in Procedure Time
The study will compare mean change in procedure time for pheresis sessions with the old system versus pheresis sessions with one of two new configurations.
Time frame: 1 year following new port configuration placement
Change in Use of Tissue Plasminogen Activator
The study will compare mean change in use of tissue plasminogen activator for pheresis sessions with the old system versus pheresis sessions with one of two new configurations.
Time frame: 1 year following new port configuration placement
