Abstract:
Objective To investigate the efficacy and safety of endovascular therapy for small unruptured intracranial aneurysms (sUIAs). Methods Patients with unruptured intracranial aneurysms who underwent endovascular therapy in the Department of Neurology, Guangzhou First People's Hospital from January 2008 to January 2018 were retrospectively included. According to the size of the aneurysms, they were divided into the sUIAs group (diameter <5 mm) and the non-sUIAs group (diameter ≥5 mm). Demographics, vascular risk factors, aneurysm characteristics, and treatment method, effectiveness, perioperative complications, and outcomes of endovascular therapy were compared between the two groups. Results A total of 80 patients with unruptured intracranial aneurysms were enrolled, including 33 patients with sUIAs (41.25% ) and 47 patients with non-sUIAs. The age of patients (51.1 ± 9.7 years vs. 61.2 ± 8.1 years; t=5.058, P<0.001), and the maximum diameter (3.6 ± 1.1 mm vs. 8.2 ± 3.2 mm; t=7.923, P<0.001) and neck width (3.1 ± 0.5 mm vs. 4.5 ± 2.5 mm; t=3.167, P=0.002) of aneurysms as well as the proportion of patients with wide-neck aneurysm (3.0% vs. 21.3% ; χ2 =7.213, P=0.007) and stent-assisted embolization (6.1% vs. 23.4% ; χ2 =4.285, P=0.038) in the sUIA group were significantly less than those of the non-sUIAs group. The embolization results, the perioperative complication rate and the good outcome rate were comparable between the two groups. Conclusion For sUIAs, endovascular therapy is effective and safe, comparable to endovascular therapy for non-sUIAs.
