More specifically, posterior inferior cerebellar artery (PICA) aneurysms account for 0.5–3%. Aneurysms of the posterior circulation account for approximately 10% of intracranial aneurysms. Intracranial aneurysms are present in 1–6% of the population. ![]() Posterior Inferior Cerebellar Artery Aneurysms: Comparison of Results of Surgical and Endovascular Managements at One Single Center.

Keywords: Aneurysm, management, endovascular, surgical, outcome, posterior inferior cerebellar artery Key Message: To decide the optimal treatment of PICA aneurysms, cooperation between microvascular and endovascular neurosurgeons is essential and necessary. To obtain the best treatment outcomes, cooperation between interventional neuroradiologist and endovascular neurosurgeons in deciding the optimal treatment is essential. 89.7%, P = 0.359).Ĭonclusions: This study of PICA aneurysms demonstrates that results of both treatment modalities are comparable. Clinical follow-up showed that endovascular treatment achieved better outcomes (mRS ≤2) compared with surgical treatment (96.2% vs. A lower recurrence rate was found in the microsurgical surgery group compared with the embolization group (3.4% vs. Multivariate logistic analysis showed that treatment modality was the only predictor for treatment-related complications. Treatment-related complications occurred in one patient in the embolization group compared with 9 in the microsurgical surgery group (3.8% vs. Endovascular treatment was performed in 26 patients and surgical clipping in 29 patients. Results: A total of 55 PICA aneurysms were identified, 13 were ruptured, and 42 unruptured. Multivariable logistic analysis was used to find statistically significant predictive factors for treatment-related complications. Patients' demographic features, treatment-related complications, and long-term angiographic and clinical outcomes (modified Rankin Scale ) between the two groups were compared. Materials and Methods: Between January 2011 and December 2015, patients with PICA aneurysm who underwent surgical and endovascular treatment were retrospectively collected and reviewed. ![]() Source of Support: None, Conflict of Interest: NoneĪims: The objective of this article is to report our experience with the two treatment approaches in patients with PICA aneurysms and find predictive factors for treatment-related complications.
