Vascular Access options for Apheresis
PERIPHERAL
Peripheralcannulation
Non-Tunneled
CVC
Tunneled CVC

USG-PIVA Via one arm Via artery
Advantage / disadvantage of VADs
ACCESS DEVICE ADVANTAGE DISADVANTAGE
Peripheral access � “Quick” bedside insertion� Low complication rates� Cheap
� Difficult in patients with ‘no veins’
� Needs patient’s cooperation� Limited inlet flow rates
Peripheral access using an ultrasound
� >90% patients have adequate veins on US
� Avoids CVC insertions
� Requires a new skill-set� Expensive equipment
Central venous access
� High inlet flow rates� Can stay in situ permanently
(i.e., Ports)
� More severe complications � Requires planning - consent,
IR slot, CVC team, etc.
Arteriovenous fistula / graft
� Can provide permanent and effective vascular access
� Requires surgery� Requires staff training / input
from renal team
Complications
� Central VAD� Pneumothorax
� Haemothorax� Air embolism� Venous thrombosis
� “Pinch off” syndrome� Infection� Artery / nerve damage
� Etc.
� Peripheral VAD� Infection
� Phlebitis� Infiltration� Artery / nerve damage
� Dislocation� Stenosis

Prospective study TPE, RBC exchange, CC
186 pt’s; total of 831 procedures20% decrease of pt’s needing CVC
Mayhew and Stylianou(2017)
Retrospective study
CC 203 pt’s; total of 383 procedures.Decreases CVC insertion from 33% to 7% over the study period

Prospective, descriptive study
TPE, ECP, CC Implementation of USG-PIVA in apheresis unit: decrease of CVC insertion from 45.8% (125 CVCs) to 13.2% (30 CVCs)
How to increase the number of peripherally placed cannulas?
�Elective Procedure? Make pre-procedure vein assessment mandatory
�Consider required Inlet Flow rates �Cooperation (i.e., patient, parents, play specialist)
�Consider access sites beyond the ACF area
�Consider type of peripheral vascular access device
�Utilise vein-enhancing methods (e.g., warmth, hydration, etc.)
�Use technology (e.g., near infrared light or ultrasound devices)�Etc.
