Risk factors analysis of mirror aneurysms: A multi-center retrospective study based on clinical and demographic profile of patients

Characteristics of Radiation-Related Intracranial Aneurysms: A Multicenter Retrospective Study

“…Unlike classic intracranial aneurysms, which are more common in women, 12 our study showed that radiation-related aneurysms were more common in men (the male-to-female ratio was 2.4:1). Previous literature reviews have documented that most patients with radiation-related aneurysms were men, 5,7,11 consistent with findings in our study.…”

“…Among all patients with intracranial aneurysms, 2641 consecutive patients were retrospectively included from 3 hospitals (Yuebei People's Hospital, The Second Affiliated Hospital of Guangzhou Medical University, and Zhujiang Hospital) from January 2005 to June 2014, as previously described, 12 and the following 1519 patients were recruited consecutively from a single center (Yuebei People's Hospital) between July 2014 and March 2020. The demographic profiles and cerebrovascular risk factors (including diabetes, hypertension, and hyperlipidemia) were collected for this study through chart reviews on each site.…”

“…As previously described, the sites of the aneurysms were categorized by 4 locations: 1) the anterior cerebral artery (including the anterior communicating artery and anterior cerebral artery); 2) the MCA; 3) the ICA, including the ICA terminus, posterior communicating artery, cavernous ICA; and 4) the posterior circulation arteries (including the posterior cerebral artery and the vertebrobasilar system). 12,13 The aneurysm type was dichotomized into bifurcation aneurysms if they were located at the parent artery bifurcations in the cerebral vasculature based on CTA and sidewall aneurysms if they originated from only 1 parent vessel without an artery emerging from the top of the dome. 13 The aneurysm wall was defined as an irregular wall if the blebs, lobes, or protrusions were present on the wall.…”

The rupture risk factors of mirror intracranial aneurysms: A systematic review and meta-analysis based on morphological and hemodynamic parameters

“…However, further studies are needed to confirm the cutoff. In 2017, Huang et al[27] conducted a multi-center study with 99 pairs of MIAs, 57 of which were ruptured and 114 unruptured. However, the study only analyzed patients' clinical and demographic profiles and limited morphological factors such as IA size and irregular shape.Wang et al [30] conducted a study with 68 patients and found that in PComA MIAs, AR � 0.98 and SR � 1.21 were better predictors of rupture and that anterior dome projection was an independent risk factor for rupture[31].…”
