Purpose There have been many reports on the risks of enlargement and rupture of residual aneurysms and de novo aneurysm formation in the contralateral internal carotid artery after parent artery occlusion (PAO). In the present study, we investigated the efficacy of flow diverter device placement (FDDP) for the treatment of contralateral internal carotid artery aneurysms after PAO. Methods After 11 patients, who had bilateral large or giant internal carotid aneurysms, were treated for either side with PAO or FDDP, they underwent FDDP for residual lesions in our hospital between October 2015 and June 2018. The patients were divided into two groups, depending on the prior procedure: PAO or FDDP. The embolic state after subsequent FDDP was evaluated by angiography. The embolic state was graded using the O’Kelly Marotta scale. Patients’ characteristics and the embolic state of intracranial aneurysms after FDDP were compared between the two groups. Results Comparing patients’ characteristics between the PAO group and FDDP group, statistically significant differences were observed in laterality of the lesions and the interval between prior treatment and FDDP for residual aneurysms ( p < 0.05). The embolic state at the one-year follow-up revealed that there could be significantly sufficient embolisation in the FDDP group ( p < 0.05). Conclusion When FDDP is performed for the contralateral lesion after PAO treatment, it is difficult to attain sufficient embolisation of intracranial aneurysms because haemodynamic load in this procedure is large compared to that in a regular FDDP.

Background To evaluate the feasibility and efficacy of the pipeline embolization device in the treatment of unruptured intracranial mirror segment aneurysms. Methods Out of a total of 338 subjects, 14 were identified harboring a total of 32 internal carotid artery mirror segment aneurysms that were treated with the pipeline embolization device and were consecutively enrolled into our study. We collected data on patient demographics, modified Rankin scale (mRS) at admission, aneurysm characteristics, clinical outcome at discharge, 3–9 and at 12–18 months as well as angiography results at follow-up. Results Patients’ mean age was 52.9 years; baseline mRS was 0 in all subjects. Pipeline embolization device placement was successful in all cases. Post-treatment mRS remained 0 in 13/14 patients. One patient experienced a small intraparenchymal hemorrhage and subarachnoid hemorrhage, associated with a frontoparietal infarction resulting in right upper extremity weakness and aphasia (post-treatment mRS 3). His mRS evaluation remained stable at the 3–9-month follow-up. Three to 9-month follow-up angiography (13/14 subjects) showed complete aneurysm occlusion in 24/30 aneurysms (80%), near complete and partial occlusion in three of 30 (10%) aneurysms each. At the 9-month follow-up, one patient experienced a complete occlusion of the anterior temporal artery branch but did not present with any clinical deficits. No mRS changes were encountered over a median 6-month follow-up period. Mid-term follow-up angiography (12–18 months) available in eight of 14 subjects showed complete aneurysm occlusion in all patients. Mild intimal hyperplasia was observed in one patient. Conclusions Flow diversion technology can be used for the treatment of unruptured mirror segment aneurysms in selected patients.

In recent years there has been a progressive increase in interventional neuroradiology procedures, partially due to improvements in devices, but also to the simultaneous development of technologies and radiological images. Cone beam CT (Dyna-CT; Siemens) is a method recently used to obtain pseudo CT images from digital subtraction angiography (DSA) with a flat panel detector. Using dedicated software, it is then possible to merge Dyna-CT images with images from a different source. We report here the usefulness of advanced DSA techniques (Syngo-Dyna CT, three-dimensional DSA iPilot) for the treatment of an intracranial aneurysm with a flow diverter device. Merging MR and Dyna-CT images at the end of the procedure proved to be a simple and rapid additional method of verifying the success of the intervention.

Abstract BACKGROUND AND IMPORTANCE Basilar fenestration aneurysms are rare, challenging intracranial vascular lesions with atypical anatomy. The posterior circulation represents a difficult therapeutic dilemma because of the close proximity of crucial life-sustaining brainstem structures. The use of flow diverter technology has been very limited in posterior circulation vessels. CLINICAL PRESENTATION We present the case of a 49-year-old female patient, who was diagnosed with a symptomatic large vertebrobasilar junction aneurysm, which was initially thought to be a proximal basilar dilatation. The aneurysm was later verified to arise from the proximal end of a basilar fenestration, distended by the aneurysm fundus. The small-caliber fenestration limbs were the only connection to the distal basilar artery, but were stretched laterally and concealed by the aneurysm fundus. This complex lesion was successfully treated by flow diverter deployment through one of the fenestration limbs, followed by coiling of the aneurysm fundus, and sacrificing the contralateral vertebral artery. A 6-month follow-up angiogram showed remodeling of the basilar artery and complete occlusion of the aneurysm with good clinical outcome. Careful diagnostic workup, multidisciplinary discussions, and the innovative use of versatile endovascular technology were crucial to achieve an optimal result in this case. CONCLUSION This is the first report of a successful basilar artery reconstruction for the treatment of a large atypical vertebrobasilar junction fenestration aneurysm by deployment of a flow diverter device directly in a small, obscured fenestration limb.

Giant intracranial aneurysms are defined as aneurysms that measure over 25 mm in the greatest dimension. They are rare vascular lesions that preferentially involve regions with high-velocity blood flow, such as the cavernous and supraclinoid segments of the internal carotid artery, the middle cerebral artery, the vertebrobasilar region, and the basilar apex. The treatment of giant aneurysms is challenging and associated with high rates of morbidity and mortality. Flow-diverter devices have revolutionized their treatment in recent times. We report the successful management of two patients with giant cavernous internal carotid artery aneurysms using flow-diverter devices for the first time in Nepal.
