Transcervical approach for carotid artery stenting with transitory reversal flow: Case report

subject

description

Introduction Carotid artery stenting (CAS) has been indicated as an alternative to carotid endarterectomy in high risk patients. Sometimes, an aortic arch can be anatomically unfavourable for CAS. Herein we report our experience in a case of CAS with transcervical approach. Presentation of case A 77-year-old male was referred to our hospital for severe subtotal occlusion of the left internal carotid artery. He had a past medical history of radiation to the head and neck for laryngeal cancer. Previous CT-angiography had shown a type III aortic with bovine arch. CAS via transcervical approach was performed with transitory reversal flow during the placement of RX Spider Filter 6 Fr (Medtronic, Minneapolis, MN). After release of 7 × 30 mm RX Xact carotid stent (Abbott Vascular, Chicago, IL) and ballooning with a 5.5 × 30 mm Rx Submarine balloon catheter (Medtronic Minneapolis, MN), angiography check showed a good result. Discussion The transcervical approach is an innovative technique where usually a shunt is created, either between the common carotid artery and the internal jugular vein or between the common carotid artery and the common femoral vein. This flow reversal reduces the risk of periprocedural embolic events. In our experience a short proximal clamping with transitory reversal flow, reduces the invasiveness of procedure with good outcomes. Conclusion Transcervical carotid access with transitory reversal flow is a valid alternative in complicated patient with anatomy unfit for CAS.
