Neurology: Beijing Tiantan Hospital found: intracranial ruptured small aneurysm, aspirin treatment is safe and effective

The treatment of intracranial unbromed small aneurysms (small unruptured intracranial aneurysms, UIAs) has been a controversial topic in the field of neurosurgery.
standard treatment is to observe these lesions.
less than 7mm accounted for 69.6% of ruptured aneurysms.
to determine whether a small aneurysm rupture is high risk is key to preventing fatal and disabling intracranial bleeding.
, UIAs and isovascular disease (ICVD) are detected with high-resolution MRIs more frequently.
aspirin is a standard secondary preventive drug for ICVD patients.
researchers have not yet clearly determined whether aspirin is safe for patients with ICVD.
aspirin in the short term (3 months) increases the risk of rupture of the aneurysm.
, however, has recently been described as a potential treatment because it prevents aneurysm rupture by exerting anti-inflammatory effects on the walls of aneurysms.
-Cong Weng of Tiantan Hospital in Beijing, China, and others conducted a multi-center prospective cohort study to test aspirin's safety assumptions for patients with unbroigned intracranial aneurysms.
their research team, 1,866 isohemia cerebrovascular disease (ICVD) patients were included in four hospitals from January 2016 to August 2019, all with lesions with a diameter of less than 7mm.
, they record baseline and follow-up patient information, including aspirin use.
main endpoint is an aneurysm rupture.
the main results of the study: 643 patients (37.2%) received aspirin continuously after 4411.4 years (person-years).
all patients, 12 (0.7%) had ruptures.
of vascular rupture (IRR) was 0.27 (95% CI 0.15 s0.48)/100 person years.
IRRs for non-aspirin groups and aspirin groups are 0.39 (95% CI 0.21-0.72) and 0.06 (95% CI 0.010-0.45) /100 years, respectively.
in a multivariable analysis, uncontrolled hypertension and 5-7mm UIS were associated with a high incidence of aneurysm rupture, while the use of aspirin was associated with a low incidence of aneurysm rupture.
high-risk groups (UIAs 5-7mm, accompanied by uncontrollable hypertension) IRRs were higher than in other groups.
of the study is to find that aspirin is a safe treatment for patients with both small UIAs and ICVD.
who do not take aspirin in high-risk groups need to be monitored more closely.
