Objective: Treatment of complex intracranial aneurysms (IAs) is still a challenging thing and this study aims to summarize the experience of telescoping flow diverters (FDs) in treating complex intracranial aneurysms.
Method: Between April 2013 to November 2020, 381 IA cases treated by flow diverters (FD) were retrieved from the database of 4988 IA cases, and finally 20 cases treated by telescoping FDs were enrolled for further analysis.
Result: Among 20 patients, 15 patients (75.0%) received Tubridge telescoping while 5 patients (25.0%) received PED telescoping. The technical success rate was 100%. The immediate occlusion results were: 7 cases of OKM grade A (35.0%), 11 cases of OKM grade B (55.0%), and 2 cases of OKM grade C (10.0%). No perioperative complications occurred. The clinical follow-up was available in 20 patients (100%) and the follow-up time was 6-96 months. One patient developed massive infarction and the other 19 patients were range between 0 and 2. The angiographic follow-up was available in 17 patients (85%) and the follow-up time was 6-27 months. The occlusion results were: 1 case of OKM grade B (5.9%), 6 cases of OKM grade C (35, 0.3%), and 10 cases of OKM grade D (58.8%). 2 patients (11.8%) developed occlusion of the patent artery.
Conclusion: Telescoping flow diverters showed low perioperative complications and high IA occlusion rate when treating complex intracranial aneurysms in follow-up time, which provides an alternative manner beyond conventional strategy for neurosurgeons.

To evaluate the safety and efficacy of staged coiling followed by flow diverter (FD) in the treatment of ruptured intracranial aneurysms(RIAs). A retrospective analysis was conducted on 20 patients with RIAs treated with staged coiling followed by FD at a single center, between April 2015 and September 2024. Patient demographics, aneurysm characteristics, clinical and imaging outcomes were reviewed.

Article Synopsis
- The study retrospectively analyzed data from 174 patients with unruptured intracranial aneurysms treated with flow-diverter devices between January 2020 and January 2024, focusing on perioperative complications and adverse events.
- Out of the procedures, 16.7% experienced intraoperative issues, with complications in 5.7% of patients and neurological deficits in 2.9%.
- Overall, the flow-diverter devices showed a satisfactory healing rate, with 77.7% of aneurysms achieving successful occlusion based on the O'Kelly-Marotta grading system, but the occurrence of complications remains a concern.
Arterial spin labeling detects trapped labeled spins in flow-diverted aneurysms and it reflects intra-aneurysmal flow stasis.

Background: This study evaluated arterial spin labeling (ASL) imaging findings in flow-diverted aneurysms (FD-ANs).
Methods: Twenty-one patients with internal carotid artery aneurysms treated with flow-diverter stent (FDS) were included. Time-of-flight magnetic resonance angiography (TOF-MRA) and ASL were performed before and after follow-up digital subtraction angiography (DSA) on the day, 6 months, and/or 1 year after treatment.

Purpose: Flow-diverter (FD) stents were developed to treat aneurysms that are difficult to treat with conventional coiling or surgery. This study aimed to compare usefulness of Silent MRA and TOF (time of flight) -MRA in patients with aneurysms after FD placement.
Materials And Methods: We retrospectively collected images from 22 patients with 23 internal carotid artery aneurysms treated with FD.
