uThe patient was consulted to the interventionalneuroradiology department. Diagnostic catheterangiographiy confirmed dissecting aneurysm(image1). Subsequently the aneusysm was treatedwith a flow diverting stent without any complications(image2).
uDissecting aneurysms (DA) of the ICA can occurspontaneously or in association with variousetiological factors including craniomaxillofacialtrauma, head and neck surgeries, hyperextension orhyperflexion of the neck, fibromuscular dysplasia, and connective tissue disorders such as Ehlers-Danlos and Marfan syndromes.
uIt is suggested that DAs are associated with strokerisk, either as a source of embolization or viaexpansion and compression. The management of ICA dissection is debatable but can be divided intomedical, surgical, and endovascular interventions.
Management options include anticoagulant andantiplatelet therapies to prevent cerebral embolizationof the dissecting vessel, permanent occlusion of thetight stenosis, surgical vascular bypass, ligation, andresection and grafting of the damaged vessel andendovascular stenting. Endovascular stenting is a lessinvasive modality which allows immediaterecanalization and preservation of the artery.
uUtilization of conventional angiography helps toestablish the diagnosis and provides a safetherapeutic option for DAs.
