Abstract:
Objective To explore the clinical and imaging efficacies of stent-assisted embolization and flow diversion in the treatment of intracranial aneurysms ≥10 mm. Methods Eighty-six patients with intracranial aneurysms≥10 mm, admitted to our hospital from January 2012 and February 2018, were chosen in our study; all 22 patients with ruptured aneurysms accepted stent-assisted embolization. Singular stent-assisted embolization was used in 55 patients, multiple stent-assisted embolization was used in 18 patients, and flow diversion was used in 13 patients. The immediate postoperative complete occlusion rate, complication incidence, and clinical and imaging follow-up data were retrospectively analyzed. Results (1) Results of immediate postoperative complete occlusion:Raymond grading I was noted in 56 patients, grading II in 6 patients, and grading III in 24 patients. Significant differences on immediate postoperative complete occlusion rates were noted among the three group (P<0.05); one patient had intra-stent thrombosis in the patients from singular stent-assisted embolization group, one patient with middle cerebral artery aneurysm had contralateral muscular dysplasia resulted from perforator occlusion and one patient with basal aneurysm had dysarthria resulted from perforator lesion in the patients from multiple stent-assisted embolization group; no perioperative complication was noted in patients from flow diversion group. (2) The prognosis of 86 patients was good;imaging follow-up results showed that 32 patients had occlusion, 7 had neck residue and 16 had recurrence in the singular stent-assisted embolization group; 11 patients had occlusion, one had neck residue and 6 had recurrence in the multiple stent-assisted embolization group; 11 patients had occlusion and 2 had neck residue in the flow diversion group; there were no statistically significant differences in follow-up results of aneurysms among the three groups (P>0.05). Conclusion Both flow diversion and stent-assisted embolization are effective methods for treatment of intracranial aneurysms≥10 mm.
