Abstract
Background:
Silicone Cuffed Centrally Inserted Central venous catheters (CICCs) were a type of catheters that have been used for a long time especially in cancer patients. Recently, thanks to biomedic research progresses, polyurethane catheters have resulted in higher surgical performances compared to classical silicone ones. Indeed, the inferior calibers of these new catheters lead to an extremely faster infusion rate. The presence of a valve at the tip of the catheter could suggest an impossible replacement procedure over a Seldinger guidewire.
Method:
The aim of this article is to explain our replacement technique over guidewire of silicone cuffed and valved tunneled CICCs with a power injectable polyurethane cuffed tunneled CICC. The casistic presented was evaluated at the Vascular Access Unit of ASST Spedali Civili in Brescia, Italy. The study involved 35 successful catheter replacement over guidewire, meanwhile cases where patients presented sepsis, exit site infection, or catheter damage were premeditatedly excluded.
Results:
The maneuver was always conducted following the same procedure without noticing particular complications associated with CICC insertion. Indeed, the operation was quick, feasible, and safe. Septic, thromboembolic, or hemorrhagic complications also related to patients presenting dysfunctional coagulation cascade were not encountered.
Conclusions:
Our experience regarding the replacement technique of silicone cuffed and valved catheters over guidewire was considered feasible, accurate, and efficient for all patients treated, even in those presenting thrombocytopenia or a dysfunctional coagulation cascade.
