Background:Tiny false intracranial rupture aneurysms are particularly rare. It is challenged both to neurosurgery and endovascular ***:We present here five rare cases of perforator tiny aneurysms that were diagnosed based on DSA. These patients were found due to SAH, and they decided to treat these aneurysms with endovascular therapy. After numerous attempts, the coiling microcatheter failed to access the aneurysms. As a result, the aneurysms finally were treated with guidewire ***:Mean follow-up time was about 10.4 months. The outcomes of the 5 cases were all surprisingly excel ent. The patients were followed up with angiography and telephone till now. No revascularization of aneurysm was ***:This paper demonstrated for the first time to our knowledge that tiny false intracranial aneurysm may be treated with guidewire manipulation. While larger studies with long-term follow-up are required to validate these promising results, guidewire manipulation is a new approach worth considering when microcatheter cannot enter aneurysm.

Background: To examine whether embolization of dural or pial blood supply branch is more efficient for symptom alleviation for unruptured mixed dural-pial arteriovenous malformations (DPAVMs). Methods: We retrospectively reviewed 30 DPAVM patients from a database of 425 consecutive cerebral arteriovenous malformation (CAVM) patients who underwent endovascular embolization between January 2010 and December 2015 at our institution. Demographics, angioarchitectural characteristics, endovascular embolization details and patients clinical outcomes were recorded. The modified Rankin Scale (mRS), Engel‘s classification and Visual Analogue pain scale (VAS) were used to assess clinical outcomes. Results: The single center cohort data shows that the incidence of DPAVM is 7.1%. Among the 30 DPAVM patients, 9 (30.0%) are ruptured and 21 (70.0%) are unruptured. Four (19.0%) of the 21 unruptured DPAVM patients are failed to follow-up, leaving 17 to analysis the clinical outcomes. Clinical presentations of the 17 unruptured DPAVM patients are epilepsy (n=10), headache (n=5) and focal neurological dysfunction (n=2). Six patients have DPAVMs occluded via pial blood supply branches, 4 via dural branches and 7 via both pial and dural branches. Unruptured DPAVM patients with nidus occluded via dural blood supply branches, or both pial and dural branches have higher symptom alleviation rate than patients with nidus occluded via pial branches (100%/85.7% vs 66.7%). Conclusions: For DPAVM patients presented with epilepsy, headache and FND, embolization via dural blood supply branches may be more efficient for symptom alleviation. Large cohort study is needed to confirm the generalizability.

Background:We investigated whether periodontal diseases,specifically,periodontitis and gingivitis,could be risk factors of the incidence of intracranial aneurysms(IAs).Methods:We performed a case–control study to compare the differences in the periodontal disease parameters of 281 cases that were divided into the IAs group and non-IAs *** cases underwent complete radiographic examination for IAs and examination for periodontal ***:Comparing with those in the non-IAs group,the cases in the IAs group were older(53.95±8.56 vs 47.79±12.33,p50 years)and hypertension were predictive risk factors of aneurysm formation(odds ratio[OR]1.047,95%confidence interval[95%CI]1.022–1.073,plinical attachment loss,and alveolar bone loss,were significantly associated with the occurrence of IAs(all p1.1 and plaque index>1.5)had the correlation with IAs formation(p=0.007 and p<0.001).Conclusion:Severe gingivitis or periodontitis,combining with hypertension,is significantly associated with the incidence of IAs.
