Abstract

Purpose

Since appearance of the balloon-remodeling technique and stent-assisted coiling, complex aneurysms have been treated successfully by endovascular means worldwide. Although these two techniques have been widely proven, the combination of both traditionally made the procedures more complicated technically. The aim of our study was to determine the technical success, safety, and efficacy of the low-profile stents delivered through double lumen balloons.

Methods

Clinical, procedural, and angiographic data were analyzed.

Results

Eighty-four patients (55 women; age range 20–81 years) harboring 86 aneurysms were included in this study. Aneurysm maximal diameter ranged from 2 to 26 mm, with mean 7.5 mm. There were 62 unruptured, 15 recanalized, and 9 acutely ruptured aneurysms. Aneurysm locations were ACoA (31), MCA (36), supraclinoid ICA (4), carotid bifurcation (2), basilar (7), PCA (3), PICA (2), and VA (1). Ninety-three devices were implanted (63 LVIS jr, 15 LEO Baby, 14 ACCLINO Flex and 1 Neuroform Atlas) through the double lumen balloons (Scepter C or XC and Eclipse 2 L). We found 2 minor clinical events (2.4%) and 1 major event (1.2%). Total intra-procedural technical complication rate was 11.6%. Follow-up was available for 71 patients with an average follow-up of 7 months. Complete and near complete occlusion was 90.1%. Residual aneurysms were seen in 9.9%.

Conclusion

The “combined remodeling technique” with low-profile stents delivered through double-lumen balloons is technically feasible, safe, and effective for the treatment of intracranial aneurysms. This technique allows the operator to avoid extra maneuvers.
