Abstract
Objective: To describe the clinical utility and technical aspects of the candy-plug technique using an Excluder aortic extender (Ex-cuff) for false lumen (FL) occlusion in chronic aortic dissection.
Materials and Methods: This is a retrospective study analyzing seven consecutive patients (mean age, 63 years; range, 44–78 years; 6 men) with aneurysmal dilatation or rupture in chronic aortic dissection. All patients had undergone thoracic endovascular aortic repair with FL occlusion using this technique. We assessed technical (deployment accuracy) and clinical (no FL backflow on the latest contrast-enhanced computed tomography) success.
Results: Technical success was obtained in six patients (86%). Technical failure was caused by the malposition of the candy-plug. The mean follow-up period was 593 days (range, 222–1225 days). Clinical success was obtained in four (57%), and incomplete Amplatzer Vascular Plug (AVP) embolization was seen in two. There was no enlarged FL after the procedure, and all patients are alive during the follow-up periods.
Conclusion: The candy-plug technique using an Ex-cuff may be a feasible option; however, it takes time to achieve complete AVP embolization. Therefore, using additional embolic materials should be considered when we use it for the rupture case. (This is a translation of Jpn J Endovasc Interv 2018; 19: 29–35.)
