PURPOSE: To evaluate the angiographic outcomes of the Optima™ coil system in the endovascular treatment of saccular intracranial aneurysms to present real-world experiences.
METHODS: The study encompassed patients with both ruptured and unruptured aneurysms who underwent treatment with the Optima™ coil system. A retrospective analysis was conducted to examine patient and aneurysm characteristics, complication rates, and angiographic outcomes.
RESULTS: The total of 326 Optima™ coil implantations was performed in 64 aneurysms, with a mean maximum diameter of 7.49 ± 3.08 mm (range: 2.5-16.5 mm), among 64 patients (37 females and 27 males, mean age: 53.34 ± 14 years old). The average number of implanted coils was 5.06 ± 1.73. The mean packing density was 26.2% (range = 19.2-34.6), observed to be significantly higher in aneurysms with complete occlusion and neck remnants compared to those with a residual dome (p < 0.01). The mean follow-up period was 15.9 ± 8.1 months. One case (1.5%) reported a coil malfunction attributed to coil stretching. The mortality rate was 3.1% (n = 2).
CONCLUSION: The Optima™ coil system exhibited safety and efficacy in the endovascular treatment of both ruptured and unruptured intracranial aneurysms, demonstrating favorable angiographic outcomes. Nevertheless, further studies are necessary to validate these results over the long term.
