Optimal woven endobridge (WEB) device-aneurysm volume: using automated volumetric software to predict aneurysmal occlusion status after WEB treatment
Background
Optimal Woven EndoBridge (WEB) sizing is crucial for successful implantation. We used three-dimensional (3D) software, Siemens Aneurysm Analysis v. VD30B, to determine the potential of WEB device-aneurysm volume (DAV) ratios in predicting post-treatment occlusion status.
Methods
We retrospectively reviewed 35 unruptured intracranial wide-neck bifurcation aneurysms treated using the WEB. The study evaluated the association between the DAV ratio and aneurysm obliteration during follow-up. The primary aim of the study was to determine the optimal DAV ratio for predicting occlusion status following WEB treatment.
Results
The success rate of treating all unruptured aneurysms with the WEB was 100%. The median duration to final follow-up was 365 ± 184.0 days with all 35 patients having a mean modified Rankin Scale score of 0. One (2.9%) patient experienced a transient ischemic attack with hemiparesis perioperatively. A follow-up angiography revealed complete occlusion (WEB Occlusion Scale [WOS] A and B) in 25 (71.4%) of 35 patients and WOS C and D in 10 (28.6%) of 35. The median DAV ratio significantly differed between the groups. The median DAV ratios were 0.97 in the complete occlusion group and 0.84 in the WOS C and D group, respectively (p = 0.002). A receiver operating characteristic curve produced an area under the curve of 0.76 (confidence interval: 0.56–0.96). The optimal DAV ratio cut-off and the highest Youden index for complete occlusion was 0.90.
Conclusion
Calculating DAV ratios using 3D software may help improve the rate of complete occlusion following WEB treatment.
期刊介绍：
The journal "Acta Neurochirurgica" publishes only original papers useful both to research and clinical work. Papers should deal with clinical neurosurgery - diagnosis and diagnostic techniques, operative surgery and results, postoperative treatment - or with research work in neuroscience if the underlying questions or the results are of neurosurgical interest. Reports on congresses are given in brief accounts. As official organ of the European Association of Neurosurgical Societies the journal publishes all announcements of the E.A.N.S. and reports on the activities of its member societies. Only contributions written in English will be accepted.
