The treatment of carotid stenosis complicated by severe vessel tortuosity can present challenges in distal vessel selection and device delivery. This article reports the use of a steerable microcatheter (SM) for carotid artery stenting (CAS) in such cases. A 67-year-old male with transient lower extremity weakness and bilateral cerebral infarctions was found to have bilateral carotid stenosis. CAS was planned for both carotid arteries due to coronary artery disease. The left carotid artery exhibited severe stenosis with a 90-degree angle between the common and internal carotid artery (ICA). Anticipating difficulty in navigating the device, we used a 2.4 Fr SM. By adjusting the catheter tip to align with the ICA, we successfully guided the wire distally. Following the catheter exchange, a distal protection device was deployed, and CAS was completed successfully. SMs provide exceptional vascular selectivity and support, improving success in complex cases.
