Background:
Totally implantable access ports (TIAP) with cutdown method has few complications, but needs assessment of fluoroscopic system.
Methods:
We present a method to confirm the position of TIAP catheter without fluoroscopic assessment. We use the cutdown method and trigger arrhythmia while introducing the TIAP catheter.
Results:
This method was applied in 54 patients and no complications were found.
Conclusions:
Checking the position by triggering arrhythmia while performing TIAP with cephalic vein cutdown in case of C-arm was not available is simple and safe.
