Endovascular coiling versus microsurgical clipping for extremely small intracranial aneurysms: a comparative analysis of treatment strategies, complications, and clinical outcomes.

ABSTRACT:

Background

Generally, extremely small intracranial aneurysms (ESIAs) are defined as having a maximum diameter of less than 2 mm. Despite technological improvement, treating ESIAs remains challenging for neurosurgery specialists. ESIA treatment has long been controversial owing to the high risk of complications associated with both endovascular coiling (EC) and microsurgical clipping (MC). This retrospective cohort study assessed postoperative complications, angiographic outcomes, and long-term clinical efficacy in ESIAs patients receiving EC or MC interventions. The objective was to evaluate the effectiveness of different surgical interventions for patients diagnosed with ESIAs.

Methods

Patients who underwent EC or MC between February 2013 and December 2023 were retrospectiv
