Covered Stent Delivery in Tortuous Internal Carotid Artery for Treatment of Direct Carotid Cavernous Fistula
Neurocirugía(2023)
摘要
Direct carotid cavernous fistulas (dCCF) are high-flow shunts between the internal carotid artery (ICA) and cavernous sinus and are commonly caused by traumatic injuries. Endovascular intervention using detachable coils, with or without stenting, is often the treatment of choice; however, migration or compaction of the coils can occur due to high-flow nature of dCCFs. Alternatively, deployment of a covered stent in ICA can be considered for treatment of dCCFs. We report a case of dCCF with tortuous intracranial ICA successfully treated by placement of a covered stent graft and we will illustrate the technical aspects of the procedure. In the presence of a tortuous ICA navigation and deployment of covered stents is technically complicated and requires modified maneuvers.
