Methods: Forty-one patients who received 77 radioembolization procedures with G5 (2014–2015) were retrospectively matched with 41 patients (77 radioembolization procedures) who received radioembolization with WFI (2011–2014) at our center. The need for on-demand pain medication was chosen as an objective and accessible measure of periprocedural pain experienced by patients. Results: Patients were well matched according to sex, age, tumor type and involvement, and prior antiangiogenic therapies. Periinterventional analgesic requirements were significantly lower for radioembolization procedures performed with G5 than WFI: 5 of 77 (6.5%) versus 29 of 77 (37.7%), P ≤ 0,001, respectively. Early stasis (defined as slowed antegrade flow, before total vascular stasis) occurred in 12 of 154 (7.8%) radioembolization procedures overall and was not different (P ≤ 0.229) between the 2 groups (4/77 [5.2%] vs. 8/77 [10.4%]). Conclusion: Slow pulsatile administration of 90Y-resin microspheres with WFI is associated with a low rate of stasis. Replacement of WFI with G5 significantly reduces the need for periprocedural analgesia. These data favor the use G5 for 90Y-resin microsphere implantation in daily practice. ER -
