Aim:This study aimed to compare the clinical outcomes of Target 360 nano (TG) and Microplex hypersoft 3D (MH) used as a finishing coil (FC). Material and Methods:From January 2018 to December 2020, we retrospectively reviewed 243 coil embolization procedures performed using TG (n=152) and MH (n=91) coils of 1mm x 2 cm the same size as FC. Further, the clinical and radiographic results were compared by matching the propensity score between the two groups.Results:There were no statistically significant differences in the clinical and angiographic results of the two coils after the propensity score matching. Successful occlusion was 89% and 86.8% and FC insertion failure was 20.9% and 28.6%. There were no differences in procedure-related complications and recurrence between the groups during the eight months follow-up period (3.3% versus 4.4% and 4.4% versus 3.3%, respectively). We also compared two subgroups of failed FC insertion (19 of TG and 26 of MH). The number of angled catheters was significantly higher in the failed TG group than in the failed MH group.Conclusion:There was no statistically significant difference between the clinical and radiological outcomes of TG and MH used as FC. However, in the FC insertion failure subgroups, the number of angled catheters was significantly higher in the TG failed group than in the MH failed. It was experimentally confirmed that the angle change of microcatheter tip with a large angle was large; however, further studies are required.
