Clinical Trial Summary

The optimal consensus concerning treatment of incidental small paraclinoid unruptured intracranial aneurysms (UIAs) remains controversial. The aim of this prospective study is to reveal the natural history of small paraclinoid UIAs with the goal of informing the treatment plan.


Description:

A prospective observational study will be conducted in 13 Korean centers enrolling a consecutive series of 645 patients with small paraclinoid unruptured intracranial aneurysms (UIAs) from 2015 to 2017. The investigators defined the cohort population as adults(20 years old or more) with small (less than 5mm) unruptured paraclinoid aneurysm. To determine the growth rate and risk factors, the angiographic features based on MRA or CTA(ex) size, arterial relationship, multiplicity)and the clinical characteristics (ex) age, hypertension (HTN), diabetes mellitus(DM), Hyperlipidemia, smoking) are recorded at initial visit, 1 year, 2years, 3years, and 5years. The cumulative risk and the risk factors of aneurysmal rupture and growth will be analysed.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of increased maximal diameter of enrolled paraclinoid aneurysms on follow up MRA or CTA If, the maximal diameter(in mm) of aneurysm which is measured by 1 neurosurgeon and 1 neuroradiologist on follow up MRA or CTA (1,2,3,5 year follow up) is 1.5 times bigger than on initial MRA or CTA, investigators will decide that the aneurysm is increased. within 5years after enrollment
Primary Number of rupture of enrolled paraclinoid aneurysms annual rupture rate within 5years after enrollment
Secondary Mortality rate of enrolled patients(related to rupture of aneurysm or not) death due to ruptured aneurysm within 5years after enrollment
Secondary Number of participants with worsened modified Rankin scale score from 0(No symptom at all) to 6(Dead) within 5years after enrollment
Secondary Number of participants with worsened Karnofsky Performance Status scale from 0(Dead) to 100(Normal) within 5years after enrollment
Secondary Treatment(due to growth or rupture) rate of enrolled aneurysms within 5years after enrollment
