Background:

Intracranial aneurysms when ruptured cause subarachnoid hemorrhage. However, not always they rupture and some may be found by chance in an imaging study and they are called incidental or asymptomatic depending on whether or not the patient has a prior event of additional ruptured sac formerly. Treating a non-ruptured intracranial aneurysm is a challenge for foremost clinical physicians and surgeons.

Objective:

To describe the characteristics and evolution of a series of 91 incidental and asymptomatic intracranial aneurysms in patients treated at the General Hospital Camilo Cienfuegos in Sancti Spíritus between 2010 and 2020.

Methodology:

Descriptive and quantitative study with a non-probabilistic sample of 91 incidental and asymptomatic aneurysms found in 72 patients through imaging studies. The

variables studied were: age, sex, dimensions, irregular shape, site of location, method of treatment used, mortality and morbidity.

Results:

Patients aged between 45 and 65 years predominated with a predominance of female sex. The majority were medium-sized aneurysms and the most frequent location was the anterior connecting aneurysm. Clinical and morphological variables predictive of complications were detected. Patients who did not undergo surgery had a better evolution. Several patients with first and second relatives’ degree affected by intracranial aneurysms were detected.

Conclusions:

Non-ruptured intracranial aneurysms predominate in women in the fifth and sixth decade of life. Morphological factors such as sac size, maximum dome height and aspect ratio were related to the happening of complications in operated patients. Family intracranial aneurysm syndrome should be considered in patients with a history of first and second relatives’ degree affected by intracranial aneurysms.
