“…Recently, Fiorella et al (2) reported good outcomes with Neuroform stents (Boston Scientific, Fremont, CA, USA) to reconstruct the ICA. Some authors reported coiling with the assistance of closed cell stents with their own limitations and complications (5,7,8,10,11,17).…”

“…Another commonly used method involves the initial placement of the microcatheter for coil delivery into the aneurysm and jailing of the catheter against the vessel wall by stenting. Despite increasing clinical experience and technological improvements, stent-assisted coiling still has inherent risks of morbidity and mortality [4][5][6][7] .

Despite experience and technological improvements, stent-assisted coiling for intracranial aneurysms still has inherent risks. We evaluated peri-procedural morbidity and mortality associated with stent-assisted coiling for intracranial aneurysms. Patients with cerebral aneurysms that were broad-based (>4 mm) or had unfavorable dome/neck ratios (<1.5) were enrolled in this study between February and November 2011 at our center. Aneurysms were treated with the self-expanding neurovascular stents with adjunctive coil embolization. Seventy-two consecutive patients (27 men and 45 women; 22–78 years of age; mean age, 52.8 years) underwent 13 procedures for 13 ruptured aneurysms and 64 procedures for 73 unruptured aneurysms. Nine [11.7%, 95% CI(4.5%–18.9%)] procedure-related complications occurred: one and eight with initial embolization of ruptured and unruptured aneurysms, respectively. Complications included six acute in-stent thromboses, one spontaneous stent migration, one post-procedural aneurysm rupture, and one perforator occlusion. Three complications had no neurologic consequences. Two caused transient neurologic morbidity, two persistent neurologic morbidity, and two death. Procedure-related neurologic morbidity and mortality rates, respectively, were as follows: overall, 5.2% (95%CI, 0.2%–10.2%) and 2.6% (95%CI, 0%–6.2%); ruptured aneurysms, 7.7% (95%CI, 0%–36%) and 0% (95%CI, 0%–25%); unruptured aneurysms, 4.7% (95%CI, 0%–9.9%) and 3.1% (95%CI, 0%–7.3%). Combined procedure-related morbidity and mortality rates for ruptured and unruptured aneurysms were 7.7% (95%CI, 1.7%–13.7%) and 7.8% (95%CI, 1.8%–13.8%), respectively. Stent-assisted coiling is an attractive option for intracranial aneurysms. However, stent-assisted coiling for unruptured aneurysms is controversial for its comparable risk to natural history.

“…From then on, with improvements in microstent technology, more reports from various centers describing the experimental and clinical use of different stents for embolization assistance has reported good results in the literature. [7][8][9][10][11][12][13] Up till now, several literatures have demonstrated the technical feasibility, efficacy of treating complicated intracranial aneurysms. [14][15][16][17] The stent can provide a permanent scaffold across the aneurysm neck, which may prevent coil prolapse into the parent artery and allow for safer packing of the aneurysm with a denser coil mesh.…”
