NCT05907902

Brief Summary

The management of small unruptured intracranial aneurysms (UIA) with ischemic cerebrovascular disease (ICVD) has been a very controversial topic in neurosurgery. Thus, we initiated a multicenter, prospective, randomized controlled trial (PROBE) design to elucidate in UIA patients with ICVD who do not qualify for preventive endovascular or neurosurgical intervention whether aspirin treatment decreases the risk of aneurysm growth and rupture.

Outcome Measures

Primary Outcomes (1)

  • number of participants with aneurysm rupture or growth

    primary composite outcome involving aneurysm growth ((1) ≥1.0mm in at least 1 direction by identical imaging modalities, (2) ≥0.5 mm in 2 directions by identical imaging modalities, and (3) an indisputable change in aneurysm shape) or rupture on repeated magnetic resonance- or CT-angiography within 24 months after randomization.

    24 months

Secondary Outcomes (10)

  • number of participants with aneurysm rupture

    24 months

  • number of participants with aneurysm growth on repeated angiography

    24 months

  • degree of C-reaction protein level change

    24 months

  • degree of cytokines level change

    24 months

  • recurrent or new ischemic events

    24 months

  • +5 more secondary outcomes

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients aged more than 18 and less than 80 years
  • patients with UIAs \< 5 and ≥2 mm in the greatest diameter confirmed by MR angiography (MRA), computed tomography angiography (CTA) , or digital subtraction angiography (DSA)
  • patients with either symptomatic ICVD (ischemic stroke or transient ischemic attack) or asymptomatic ICVD (clinically silent lacunar infarction identified on brain CT/MR imaging)
  • last aneurysm imaging with either CTA or MRA or DSA within the last 3 months
  • ability of the subject to understand character and individual consequences of clinical trial
  • patients who provided written informed consent
  • patients who consented to follow-up imaging with the same MR angiography or CT angiography modality

You may not qualify if:

  • multiple aneurysms
  • a history of intracranial aneurysm rupture-related hemorrhage
  • a family history of intracranial aneurysm
  • a history of vascular malformation (brain arteriovenous malformation, moyamoya disease, arteriovenous fistula, etc.), brain tumor, hydrocephalus, or hypertensive cerebral hemorrhage etc.
  • MR contraindications (metallic implant, contrast medium allergy, claustrophobia, etc).
  • a precondition modified Rankin Scale (mRS) score \> 2
  • fusiform or daughter sac UIAs
  • an allergy to aspirin
  • other contraindications for aspirin not yet mentioned, in the dosage of 100 mg/day (e.g. bleeding disorders, gastric or intestinal ulcers, acute liver failure or kidney failure, severe heart failure, treatment with methotrexate in a dosage 15 mg/week or above)
  • pregnancy and lactation
  • participation in another clinical trial or observation period of competing trials
  • residence in a rural area that prevented regular follow-up
  • poor compliance
