Procedural Complications and Factors Influencing Immediate Angiographic Results after Endovascular Treatment of Small (<5 mm) Ruptured Intracranial Aneurysms.

Background And Objective: There are technical challenges to complete occlusion of small (<5 mm) ruptured intracranial aneurysms (SRAs) using endovascular treatment (EVT). This study analyzed factors influencing immediate angiographic results in SRAs after EVT.

Material And Methods: Intraoperative angiograms and medical records of 290 patients, who underwent EVT for SRAs at 2 stroke centers in China between January 2009 and October 2016, were retrospectively reviewed and evaluated.

Endovascular Treatment of Small Ruptured Intracranial Aneurysms (<5 mm) : Long-term Clinical and Angiographic Outcomes and Related Predictors.

Purpose: To investigate the long-term clinical and angiographic outcomes and their related predictors in endovascular treatment (EVT) of small (<5 mm) ruptured intracranial aneurysms (SRA).

Methods: The study retrospectively reviewed patients with SRAs who underwent EVT between September 2011 and December 2016 in two Chinese stroke centers. Medical charts and telephone call follow-up were used to identify the overall unfavorable clinical outcomes (OUCO, modified Rankin score ≤2) and any recanalization or retreatment.

Lower miR-143/145 and higher matrix metalloproteinase-9 levels in circulation may be associated with intracranial aneurysm formation and rupture: A pilot study.

Objectives: We analyzed the relationship between plasma miR-143/145 and serum MMP-9 in patients with unruptured or ruptured intracranial aneurysms (IAs) to identify new biomarkers for predicting rupture in IAs.

Patients And Methods: We prospectively enrolled 24 consecutive patients, including seven patients without IAs as a control group, nine patients with unruptured IAs, and eight patients with ruptured IAs (enrolled within 3 days after rupture). Plasma miR-143/145 and MMP-9 were measured in blood samples collected from the femoral artery.

Number of Cigarettes Smoked Per Day, Smoking Index, and Intracranial Aneurysm Rupture: A Case-Control Study.

Background And Purpose: We aimed to investigate the effect of smoking on the risk of intracranial aneurysm (IA) rupture (IAR), specifically relationship between the number of cigarettes smoked per day (CPD) or smoking index and the risk of IAR.

Methods: We performed a single-center case-control study of consecutive patients evaluated or treated for IA at our institution from June 2015 to July 2016. Cases were patients with a ruptured IA.

Comparison of Recanalization and In-Stent Stenosis Between the Low-Profile Visualized Intraluminal Support Stent and Enterprise Stent-Assisted Coiling for 254 Intracranial Aneurysms.

Objective: To compare the rates of recanalization and in-stent stenosis between the Enterprise (EP) and low-profile visualized intraluminal support (LVIS) stent deployments for intracranial aneurysms (IAs), and the factors associated therein.

Methods: Between June 2014 and July 2016, 142 patients with a total of 161 IAs were treated by LVIS stent-assisted coiling and 111 patients with a total of 142 IAs were treated by EP stent-assisted coiling at our institution. Procedure-related complications, angiographic follow-up results, and clinical outcomes were analyzed statistically.

The Siesta Habit is Associated with a Decreased Risk of Rupture of Intracranial Aneurysms.

Background: Previous studies have examined an association between the siesta habit and hypertension, as well as coronary heart disease. However, the relationship between a siesta and the risk of rupture of an intracranial aneurysm (IA) has not yet been established. We aimed to investigate the effects of a siesta on the risk of rupture of IAs.

Passive Smoking Is Not Associated with Risk of Intracranial Aneurysm Rupture in Nonsmoking Women.

Background: Active smoking is a major risk factor for intracranial aneurysm rupture (IAR); however, little is known about the effects of passive smoking on IAR. In China, female passive smoking is widespread and severe. This study aimed to assess whether passive smoking is associated with increased risk of IAR among nonsmoking women.

Bifurcation Location and Growth of Aneurysm Size Are Significantly Associated with an Irregular Shape of Unruptured Intracranial Aneurysms.

Background And Objective: Previous studies firmly proved that an irregular aneurysmal shape was associated strongly with intracranial aneurysm (IA) rupture, but it is unclear how irregularly shaped IAs form. We aimed to identify the factors related to irregular shape of IAs.

Methods: We retrospectively analyzed of consecutive patients evaluated or treated for IA at our institution from June 2015 to July 2016.

Progressive Occlusion and Recanalization After Endovascular Treatment for 287 Unruptured Small Aneurysms (<5mm): A Single-Center 6-Year Experience.

Objective: We aimed to investigate the effect of coiling for small unruptured intracranial aneurysms (UIAs) (<5 mm) on progressive occlusion and recanalization, and the dubious factors related to progressive occlusion and recanalization among UIAs without complete occlusion.

Methods: A total of 264 patients with 287 small UIAs were coiled in our institution between June 2009 and December 2014. All UIAs were divided into small (3-5 mm) and very small (<3 mm) groups, and UIAs without initial complete occlusion were divided into progressive, stable, and recanalization groups.
