- Abstract
<bold>Purpose: </bold>To present a case of successful endovascular retrieval of a monorail predilation balloon fused to an embolic protection device (EPD) in the distal internal carotid artery (ICA) of a high-risk symptomatic patient. <bold>Case Report: </bold>A 60-year-old man with documented systemic atherosclerotic disease had a severe (>70%) restenosis in the left ICA 3 years after endarterectomy. He was scheduled for carotid artery stenting (CAS) with cerebral protection; however, he developed unstable angina and was transferred to our facility, where the admitting team decided that staged CAS followed by coronary bypass grafting would be the best option. During the CAS procedure, a 6-mm AccuNet filter was passed across the lesion via a 6-F carotid sheath and deployed in the distal ICA without incident. However, the 4-x20-mm predilation monorail balloon was then advanced without visualizing the markers, resulting in inadvertent aggressive interaction that trapped the balloon's tip in the filter. Several maneuvers to separate the devices were unsuccessful. Finally, the filter/balloon combination was moved gently retrograde until the balloon was straddling the subtotal ICA lesion. The lesion was dilated to 4 mm with the balloon, and the sheath was gently advanced across the lesion as the balloon was deflated. Angiography excluded interval occlusion of the filter from the embolic debris during the aforementioned aggressive maneuvers and documented antegrade flow. The filter was slowly withdrawn into the 6-F sheath with simultaneous aspiration. A second 6-mm filter was deployed, and the procedure was completed satisfactorily. The patient did well, with no neurological sequelae. <bold>Conclusion: </bold>EPDs are an essential in carotid artery stenting and, keeping in mind the potential risks associated with their use, will help the operator avoid complications such as this one.
