Abstract
Purpose/Aim
This study aims to compare efficacy and safety of Low-profile Visualized Intraluminal Support (LVIS) stent and Pipeline Embolization Device (PED)-assisted endovascular interventions in patients with middle cerebral arterial aneurysms.
Materials and methods
This retrospective study included a total of 144 MCA patients, who went to our hospital from January 2013 to December 2017. These patients were divided into two groups: LVIS group, 81 cases; PED group, 63 cases. Then, the basic clinical characteristics were collected. The Raymond grade was used to evaluate the embolism immediately after the surgery and at six months after surgery. The Glasgow Outcome Scale (GOS) and modified Rankin scale were used at six months after surgery, and the recurrence rate was also recorded.
Results
The mean aneurysm diameter was 7.7 ± 5.1, which range from 2-25 mm. There were 25 cases with ruptured aneurysms. The results revealed that 57 (70.4%) cases in the LVIS group and 41 (65.1%) cases in the PED group presented with complete embolisms immediately after the surgery. The mean GOS score after six months was 4.6 ± 0.9 in the LVIS group and 4.6 ± 0.9 in the PED group. Furthermore, a total of 86.4% cases had a good prognosis in the LVIS group, while 87.3% cases had a good prognosis in the PED group. Moreover, recurrence was found in six (7.4%) cases in the LVIS group and in five (7.9%) cases in the PED group.
Conclusion
Both these two methods are effective and safe, with a high good prognosis rate and low recurrence. However, there was no significant difference between the PED and LVIS stent methods.
