Abstract
Background
The Woven Endo-Bridge (WEB) device revolutionized the treatment of wide-necked bifurcation aneurysms by intrasaccular flow diversion. The latest advancement is the WEB-17 system, offering greater flexibility with fewer wires, enabling treatment of smaller distal aneurysms using smaller microcatheters than the WEB-21 system.
Methods
We conducted a systematic review following preferred reporting items for systematic reviews and meta-analyses guidelines, analyzing data from seven retrospective cohort studies involving 483 aneurysms treated with the WEB-17 device. Statistical analysis computed pooled prevalence rates and 95% confidence intervals using appropriate models for each outcome and R software version 4.3.1 (R Foundation for Statistical Computing, Vienna, Austria).
Results
Technical success was achieved in 475 out of 483 aneurysms treated with the WEB-17 device, with a success rate of 98.34% (95% confidence interval (CI) = 96.72–99.17). Among the successful cases, 4.97% (95% CI = 1.60–14.39) required adjunctive devices. Adequate occlusion, defined as complete occlusion or neck remnants, was observed in 94.41% (95% CI = 88.17–97.46) of cases. Periprocedural complications were infrequent, with thromboembolic complications occurring in 4.93% (95% CI = 3.29–7.30) of cases, hemorrhagic complications in 1.28% (95% CI = 0.58–2.83), and postprocedural neurologic complications in 0.99% (95% CI = 0.31–3.14). Procedure-related morbidity was observed in 1.71% (95% CI = 0.86–3.39) of cases, and there was one procedure-related mortality reported at 0.21% (95% CI = .03–1.50). Mortality unrelated to the procedure occurred in 1% (95% CI = 0.23–4.15).
Conclusion
Our findings suggest that the WEB-17 device is associated with a high rate of technical success, favorable angiographic outcomes, and a low rate of periprocedural complications. Further research, including prospective trials, is needed to confirm these findings and establish its safety and efficacy definitively.
