Abstract:
Objective: To investigate the clinical effect and follow-up outcome of the intracranial stent overlapping technique in the treatment of unruptured vertebrobasilar dissecting aneurysms (VBDAs). Methods: Ten patients with VBDAs had 12 unruptured VBDAs were analyzed retrospectively. The patients were treated using intracranial stent overlapping technique and LEO stents (9 patients using 2 stents, 1 using 3 stents). The aneurysms were occluded by changing the hemodynamics of the aneurysmal cavities, and the parent arteries were preserved. All the patients completed clinical and imaging follow-up study. Results: Circled digit oneOf the 10 patients with VBDAs, 7 had headache, 1 had ataxia, 3 had dizziness, and 1 had facial numbness. Image examination revealed proximal segment stenosis, string and pearl sign, wave shaped, double-lumen sign, and intramural hematoma, respectively. Circled digit twoAngiography revealed contrast agent retention in the aneurysm cavity immediately after stenting. Stent migration occurred in 1 patient, but it did not result neurological dysfunction. Two patients had transient ischemia attack after stenting, it was relieved after symptomatic treatment. The remaining patients did not have any nervous system complications. Head CT scan before discharge did not revealed any new brain infarctions. Circled digit twoAngiographic examination showed that 6 dissecting aneurysms were occluded completely at 6 months after stenting and the other 6 ones were occluded partially. The patients were followed up for 8 to 27 months, and the final mRS score was 0 in 10 patients. There were no technique-related complications in the patients during the follow-up period. Conclusion: Intracranial stent overlaping technique in the treatment of unruptured VBDAs is safe and effective.
