An analysis of the factors affecting the effectiveness of WEB in the aneurysm treatment

The Journal of Neurointerventional Surgery website published an article summarizing the results of a study on the assessment of the factors determining the degree of aneurysm closure after embolization with WEB. A retrospective analysis was conducted on 113 patients with 114 aneurysms treated with the WEB device in three German centers from May 2011 to February 2018. Six months after the procedure, among 98 patients, an angiographic examination was performed to verify the degree of aneurysm embolisation. The anatomical details and procedural aspects were also examined and evaluated to determine their effect on total or partial embolization of aneurysm.
The main conclusions of the study are as follows:
• A complete aneurysm occlusion was achieved in 62.2% of patients treated with WEB.
• An endovascular retreatment was necessary in 15.3% of patients (in comparison: in the traditional method of treatment with embolization spirals, the percentage is 25%).
• In the analysis of a subgroup consisting of 71 aneurysms treated with WEB only, a correlation was observed between the initial incomplete aneurysm occlusion and the male sex and the remains of aneurysm in the angiographic study after 6 months. In addition, the analysis showed a correlation between the height of aneurysm and aneurysm recurrence.
Researchers underlined that the WEB provides a high rate of correct occlusion of the brain aneurysm even for complex wide-necked intracranial aneurysms.
We invite you to familiarize yourself with the details of the study on the website.
