We conducted a prospective multicenter clinical trial to assess its efficacy and safety in stent-assisted coil embolization. A total of 41 patients were enrolled across 6 centers. The primary endpoint of clinical success was achieved in 39 of 40 implanted cases (97.5%; 95% confidence interval, 86.8%-99.9%). These findings demonstrate the efficacy and safety of Low-Profile Visualized Intraluminal Support EVO as an assist stent for wide-neck aneurysms. Given that concerns remain regarding thrombotic risk with small-diameter devices (2.5-3.0 mm), a subgroup analysis comparing the results of small-diameter Low-Profile Visualized Intraluminal Support EVO (2.5-3.0 mm) versus those of larger Low-Profile Visualized Intraluminal Support EVO (3.5-4.0 mm) was conducted. Fifteen cases were included in the small-diameter group, and 25 were included in the comparative group. Ischemic events occurred in 1 of 15 (6.7%) patients in the small-diameter group and in 2 of 25 (8.0%) patients in the larger-diameter group, with no statistically significant difference between the 2 groups, and all events were transient or asymptomatic. At 6 months, 13 of 14 (92.9%) patients in the small-diameter group achieved complete occlusion (Raymond-Roy Class I, core laboratory adjudicated). Overall, small-diameter Low-Profile Visualized Intraluminal Support EVO did not confer a significantly higher risk of ischemic complications compared with larger-diameter devices and demonstrated favorable therapeutic potential for the treatment of wide-neck aneurysms.

Prior to 2017, the primary treatment was external ventricular drainage, and in selected patients with thick intraventricular hematoma, an anterior endoscopic approach was used primarily for intraventricular hemorrhage removal. Since April 2017, the high parietal approach technique has been used for the simultaneous removal of both thalamic hematoma and intraventricular hemorrhage in 21 patients. The high parietal approach group showed a median hematoma evacuation rate of 92.2% and, compared with the external ventricular drainage-only group, a significantly shorter duration of ventricular drainage and a lower incidence of tracheostomy.

We retrospectively analyzed 930 patients (990 procedures; 655 females, 275 males; mean age, 62.8 years) with asymptomatic anterior circulation unruptured intracranial aneurysms treated between 2003 and 2025, with a total follow-up of 7,638 patient-years (median, 8.3 years). The primary endpoint was postoperative subarachnoid hemorrhage, and secondary endpoints included all-stroke events and all-cause mortality. Incidence rates with 95% confidence intervals were calculated, and rate ratios versus natural-history cohorts (Unruptured Cerebral Aneurysm Study and Small Unruptured Intracranial Aneurysm Verification Study) and standardized incidence ratios versus the general population were computed using Poisson methods. Ten subarachnoid hemorrhage events occurred (1.31 per 1,000 patient-years; 95% confidence interval, 0.63-2.41), with most arising from untreated or de novo aneurysms; only 1 case originated from a previously clipped site, demonstrating durable protection at treated sites. Subarachnoid hemorrhage incidence was substantially lower than that reported in natural-history cohorts of conservatively managed unruptured intracranial aneurysms. In contrast, age-adjusted all-stroke incidence remained approximately 2-fold higher than in the general population (standardized incidence ratio 2.11; 95% confidence interval, 1.50-2.90; p < 0.001), driven predominantly by ischemic events. These findings indicate that microsurgical clipping effectively reduces the risk of subarachnoid hemorrhage from treated aneurysms, whereas overall cerebrovascular risk remains elevated, reflecting persistent systemic vascular vulnerability rather than failure of local treatment.

Among 373 surgically treated patients between 2016 and 2022, only 126 with reliable trauma histories were included to minimize recall bias. Patients were stratified according to antithrombotic use (warfarin, aspirin, warfarin plus aspirin, or none).

Warfarin was also associated with higher rates of bilateral hematomas, cerebral herniation, and poorer short-term functional outcomes, although most patients improved after surgical evacuation. The strict inclusion process reduced the sample size but increased the validity of the post-traumatic interval assessment, and the concept of the post-traumatic interval itself is not yet a validated clinical parameter. These findings raise the hypothesis that warfarin may shorten the latent period of chronic subdural hematoma through mechanisms of rebleeding and accelerated hematoma remodeling.
