“…However, the currently available covered stents cannot usually be navigated into the ACA due to their thickness and stiffness. 15 FD can provide a >30% rate of metal coverage when fully deployed and can change the hemodynamics of the aneurysm, causing thrombosis in the aneurysm and acting as a scaffold to promote neointimal growth. 16 In a previous report and meta-analysis, FD deployment was effective for pseudoaneurysm.…”

Traumatic anterior communicating artery (AcomA)-cavernous sinus (CS) fistula is rare. Flow diverter (FD) deployment associated with coiling may be an alternative but has never been reported. We reported such a case. A 61-year-old man who was involved in a traffic accident presented with progressive exophthalmos for 2 weeks. Digital subtraction angiography showed a fistula between the AcomA and CS. First, the fistula was coiled. Then, the FD was deployed to cover the rupture point of the AcomA. The fistula was obliterated. Postoperatively, the patient recovered well, and his eye symptoms disappeared. Follow-up angiography showed no recurrence of the fistula. Therefore, for traumatic AcomA-CS fistula, FD deployment associated with coiling may be a feasible alternative.

“…The multi-angled view afforded by the endoscope has improved the visualization of perforating arteries, especially those arising from the posterior wall of the parent artery, so it has gradually been applied in aneurysm surgery. Understanding the relationship between the aneurysm and surrounding structures before, during, and after aneurismal clipping could help ensure adequate aneurysmal clipping [27,28].…”

Objective: This retrospective study was performed to evaluate the feasibility and safety of surgically clipping intracranial aneurysms using a transcranial neuroendoscopic approach. Methods: A total of 229 patients with cerebral aneurysms were included in our study, all of whom were treated with clamping surgery at Wuhan University People’s Hospital. They were divided into neuroendoscopic and microscopic groups, according to whether or not neuroendoscopy was used for the clamping surgery. We statistically analyzed the patients’ baseline data, surgical outcomes, and complications, which were then evaluated to assess the treatment effect. Results: The baseline characteristics were not statistically significant, except for gender, for which the proportions of female patients in the two groups were 69 (56.1%) and 46 (43.4%). There were no patients with incomplete aneurysm clamping or parent vessel occlusion in the neuroendoscopic group, and there were 4 (3.8%) and 2 (1.9%) in the microscopic group, respectively; however, there was no statistically significant difference in the comparison of the two groups. The mean operative times of the two groups were 181 min and 154 min, respectively, and were statistically different. However, the mRS scores of the two groups showed no significant difference in patient prognosis. The differences in complications (including limb hemiplegia, hydrocephalus, vision loss, and intracranial infection) were not statistically significant, except for cerebral ischemia, for which the proportions of patients in the two groups were 8 (6.5%) and 16 (15.1%). Conclusions: Neuroendoscopy can provide clear visualization and multi-angle views during aneurysm clipping, which is helpful for ensuring adequate clipping and preventing complications.

“…Several studies have reported stent-assisted coiling treatment for intracranial pseudoaneurysms with different outcomes [6,8,10,12,13]. Flow diversion devices implantation with or without coils and covered stent implantation were reported to be effective as therapy of pseudoaneurysms [5,15,18,19]. However, the use of ow diversion devices accompanied with dual antiplatelet therapy before the procedure may be limited in patients with acute bleeding.…”

Objectives Optimal treatment strategies for traumatic internal carotid artery (ICA) pseudoaneurysms are controversial. The low-profile visualized intraluminal support (LVIS) device is a braided stent with a metal coverage rate between traditional laser cut stents and flow diversion devices. We report here our therapy strategy using the LVIS stent-assisted coiling for treatment of traumatic ICA pseudoaneurysms.Methods Patients with traumatic ICA pseudoaneurysms treated by the LVIS stent-assisted coiling in our center between January 2015 to June 2021 were reviewed. The complications, radiographic, and clinical outcomes of these patients were analyzed.Results A total of 12 pseudoaneurysms in 12 patients were included. Immediate postoperative angiogram showed that six (50%) aneurysms were Raymond grade 1, four (33.3%) were grade 2, and two (16.7%) were grade 3. Two patients with severe primary cranial injury discontinued treatment after the procedure. During the follow-up of the other ten patients, two patients (20%) received additional coiling because of recanalization of the pseudoaneurysm. At the last angiographic follow-up examination, all aneurysms were Raymond grade 1. Postoperative multiple cerebral infarction occurred in two patients. Of the ten patients with a mean clinical follow-up of 32.2 ± 27.9 (median, 18) months, eight patients recovered well, one patient had right hemiplegia, and one patient died of airway damage, which was unrelated to the pseudoaneurysm.Conclusions LVIS stent-assisted coiling was a feasible approach for the treatment of traumatic ICA pseudoaneurysms.
