Port Access and Needle Specifications for Port-a-Cath Devices

Introduction to Port Access

For totally implantable ports, non-coring Huber needles must be used and should not remain in place for more than one week, as recommended by the American College of Radiology, to prevent port damage and skin erosion 1

Port access requires specialized non-coring Huber needles to prevent damage to the port reservoir, with the American College of Radiology suggesting their use 1
The needle gauge selection depends on the required infusion rate, with larger gauge Huber needles allowing higher flow rates, according to the Journal of the American College of Radiology 2
The American College of Radiology recommends matching Huber needle size to clinical needs, considering factors such as patient body habitus and subcutaneous tissue thickness 2

The American College of Radiology suggests contacting the Port-a-Cath manufacturer or consulting the device's product insert to determine the appropriate Huber needle specifications for a specific port model, considering factors such as needle length and gauge 1
The needle length and gauge must be selected based on the depth of the port reservoir beneath the skin, the required infusion rate, and patient body habitus, as recommended by the American College of Radiology [1] [2]

The American College of Radiology recommends never using standard needles on implantable ports, only non-coring Huber needles, to prevent septum damage 1
The American College of Radiology advises against leaving Huber needles in place beyond 7 days to prevent skin erosion and infection risk 1
