Abstract

Background

The Guglielmi Detachable Coil introduced by the Boston Scientific Corporation has been widely used for endovascular coiling of aneurysm. Recently, Sapphire® platinum detachable coils (eV3, Irvine, CA) have been introduced for aneurysm coiling. Herein, we report our clinical experience with the Sapphire® coil to evaluate the incidence of coil related complications and the rate of aneurysm occlusion.

Methods

Consecutive patients who underwent embolization with Sapphire® detachable coils were prospectively enrolled from January 2004 to September 2004 and the data were retrospectively analyzed. Patient demographics, including age, gender, presenting symptoms, Hunt and Hess grade, Fisher grade and locations of the vascular anomalies were collected. Additionally, complications associated with the coils and rates of aneurysm occlusion were observed and the data compiled.

Results

29 patients underwent Sapphire® coil embolization for intracranial aneurysms. Mean age was 50 ± 18 (mean ± SD) years with 81% being females. Aneurysm neck reconstruction was required in 7 cases, 6 with Neuroform stent (5 unruptured aneurysms) and 1 with balloon assistance (ruptured aneurysm). In 7 cases, Sapphire® coils were used along with other coils. There were no events of thromboembolism or ruptures of aneurysms during coil embolization. However, multi-diameter coils demonstrated stretching in 4 stent-assisted cases without any adverse consequences. Complete occlusion of the aneurysm was achieved in 79.31% of the patients, neck remnant in 6.89, and partial coiling was achieved in 13.79%.

Conclusion

The Sapphire® coil could safely be used in the treatment of both ruptured and unruptured aneurysms. However, multi-diameter non-stretch resistant coils may be associated with coil stretching when used in conjunction with a stent. Further study is still required for definitive results.
