Abstract
BACKGROUND
Totally IntraVenous Acess Devices (TIVAD) are used to have long-term bloodstream access. The catheter connected to the subcutaneous chamber may be valved (TIVAD-V) or open-ended (TIVAD-O). Infectious and occlusion complications require the removal of the TIVAD. We compared the two types of catheters (TIVAD-V and TIVAD-O) in terms of time-to-removal and complication rates.
METHODS
A retrospective study of 636 patients treated for any malignancy using a TIVAD were included. TIVAD complication was defined as the occurrence of infection or occlusion requiring TIVAD removal. Risk factors of complications and time-to-removal of TIVAD were assessed by a Cox proportional hazard analysis.
RESULTS
A total of 55 TIVADs (8.7%) were removed including 47 for infection and eight for occlusion in 54 months. There was no significant difference in the frequency of complications between TIVAD-V and TIVAD-O. There was no significant difference in time-to-removal between TIVAD-V and TIVAD-O (17.0 months, IQR [10.5-25.0] and 18.4 months, IQR [11.5-22.9], p = 0.345, respectively).
CONCLUSION
There was no difference between TIVAD with valved and open catheter in terms of complications and time-to-removal in patients treated by chemotherapy.
