Background: Coil embolization is a non-invasive method for treating intracranial vascular malformations by inducing thrombus formation. It is particularly useful in management of cerebral aneurysms and avoids the risks associated with surgical clipping. Occasionally, embolic complications occur which result in transient or permanent loss of vision.
Methods: Case report of a 29-year-old Caucasian woman who underwent coil embolization and balloon occlusion of an intracavernous carotid aneurysm. Shortly thereafter she described visual changes and a droopy eyelid.
Results: Examination revealed pupillary miosis and mild ptosis of the right upper lid. Perimetry showed an arcuate scotoma superiorly and an inferonasal step in the right eye. Fundus examination revealed multiple cotton-wool spots along the peripapillary area and along the temporal vascular arcades reminiscent of Purtscher retinopathy. After 4 weeks, she had marked improvement in her visual symptoms. Most of the cotton-wool spots had resolved and the visual field had normalized. However, the ptosis and anisocoria remained unchanged.
Conclusions: Coil embolization is a non-invasive method for treating carotid aneurysms. However, it carries the risk of ophthalmic events, warranting baseline ophthalmic examinations prior to such intervention.

Background and purpose The risk of rupture increases with advancing age. However, the risk-benefit of coil embolization for elderly patients with unruptured aneurysms is controversial. This study aimed to identify factors associated with treatment primary outcomes, including risk factors for complications and aneurysm recurrence requiring re-treatment in the endovascular treatment of unruptured aneurysms in elderly patients.

Background: Polyarteritis nodosa (PAN) is a rare and serious form of systemic necrotizing vasculitis that predominantly affects medium and small-sized arteries, with central nervous system involvement being particularly uncommon. Treatment strategies are tailored according to the extent and severity of the disease. While conventional therapy includes glucocorticoids and conventional disease-modifying-rheumatic drugs (cDMARDs), biologic agents may be critical for severe and refractory cases.

Objective: Paravisceral aortic lesions present significant challenges for endovascular treatment. This retrospective analysis of consecutively treated patients from April 2017 to June 2021 aimed to analyse the outcome of primary intra-operative embolisation of aortic complicated pseudoaneurysms and gutter channels during parallel graft (PG) repair of paravisceral symptomatic aortic pseudoaneurysms.
Methods: Patients with symptomatic pseudoaneurysms of the paravisceral aorta treated with PGs using chimney or periscope configurations were included.

Coil embolization of cerebral aneurysms often encounters challenges in achieving complete filling of the aneurysm sac due to complex shapes and hemodynamic factors, frequently resulting in the formation of a residual cavity (RC) at the aneurysm neck. The hemodynamic mechanisms underlying RC formation and growth, however, remain poorly understood. Computational fluid dynamics (CFD) analysis, combined with silent MRA free from contrast agents and metal artifacts, offers a promising approach to elucidate these mechanisms, potentially enhancing the clinical management of cerebral aneurysms post-coiling.
