[Application of low profile visualized intraluminal support (LVIS)stents in assisting coil embolization of intracranial aneurysms].

Objective: To evaluate the safety and effectiveness of application of LVIS stent-assisted coiling endovascular procedures in cerebral aneurysms . Methods: The clinical data of 41 patients with intracranial aneurysms , which were performed in LVIS stent-assisted coiling endovascular therapies from June 2015 to October 2017 in The First Affiliated Hospital of Bengbu Medical College were analyzed retrospectively. 13 patients were unruptured and 28 patients were ruptured. Immediate angiography outcomes and follow-up angiography outcomes were assessed by DSA. Clinical outcomes were evaluated by modified Rankin Scale (mRS). Results: The LVIS stents were successfully delivered in 39 cases, however there were 2 cases in which the LVIS stents did not fully open.The technical success rate was 95.1%(39/41). There were 2 cases had complications during perioperation, the rate of complications was 4.9%(2/41). One was thrombus formation in operation, there was no nerve function defect.The other was infarction three days after operation and which had mild function defect(mRS grade 2). Raymond grade 1 was 31 cases, Grade 2 was 2 cases , grade 3 was 8 cases, the effective embolism rate was 80.5%(33/41). Mean follow up time was 14.4 months, 32 cases were cured, the cure rate was 78.0%(32/41), 2 cases were reappeared, the recurrence rate was 4.9%(2/41). mRS grade 0 was 16 cases, grade 2 was 24 cases , grade 2 was 1 case , the cure rate of clinical symptom is 100%. Conclusion: LVIS stent-assisted coiling is safe and effective in the treatment of cerebral aneurysms.
