Combined balloon plus stent technique for treatment of intracranial aneurysm: a systematic review and meta analysis
Background
Intracranial aneurysms are weak spots in brain vessels that are at a higher risk of rupture and hemorrhage. This review investigates the safety and efficacy of the stent plus balloon technique for intracranial aneurysm management.
Methods
PubMed, Scopus, Web of Science, and Embase were systematically searched using the related key terms such as “Stent”, “Balloon”, “Intracranial”, and “Aneurysm” until July 22, 2024.
Results
Eleven studies comprising 481 aneurysms were included. The pooled angiographic outcome rate, according to Raymond–Roy occlusion classification (RROC), for RROC1 was 64% (95% CI 50–79%, p-heterogeneity < 0.001, I2 = 87%), while for the RROC2 was 18% (95% CI 14–23%, p-heterogeneity = 0.12, I2 = 1%), and the RROC3 rate was 17% (95% CI 3–30%, p-heterogeneity < 0.001, I2 = 100%). In addition, the intraprocedural complication and adverse event rate were 17% (95% CI 3% to %32, p-heterogeneity < 0.001, I2 = 97%) and 15% (95% CI 0–30%, p-heterogeneity < 0.001, I2 = 100%), respectively. Furthermore, the overall ischemic stroke occurred in % 4 (95% CI 1–8%, p-heterogeneity < 0.001, I2 = 100%), as well as 4% (95% CI 2–10% p-heterogeneity = 0.30, I2 = 30%), respectively.
Conclusion
The balloon plus stent technique is an innovative procedure; surgeons should know about and utilize in intracranial aneurysms. Our analysis observed minimal complications and mortality during the surgical procedure, which were identical to the rates observed with alternative techniques.
