Accurate Embolization for Endoleak after F-TEVAR of Thoracic Aortic Dissection by Detachable Coils

Abstract

Objectives To evaluate the efficacy and clinical outcomes of accurate embolization of endoleaks after fenestrated thoracic endovascular aortic repair (F-TEVAR) for thoracic aortic dissections. Methods Twenty patients with endoleaks (17 type I and 3 type II) after fenestrated thoracic endovascular aortic repair (F-TEVAR) were embolized using detachable and ordinary coils. We assessed the success rate and complications of the operation, and its effects, through clinical and CT follow-up. Results The mean clinical follow-up duration was 25.68 ± 11.07 months (3–44 months). During follow-up, all endoleaks were completely embolized and aortic remodeling was improved. Secondary endoleaks occurred in four patients who were embolized twice. No other complications or death were reported. Conclusion Embolization using detachable and ordinary coils is effective and safe for the treatment of endoleaks after fenestrated thoracic endovascular aortic repair.
