| Popis: | We present the case of a tortuous intrathoracic common carotid artery (CCA) with a symptomatic right internal carotid artery lesion. This patient had a complex medical history, including a previous intraoperative cardiac arrest during attempted carotid endarterectomy (CEA) initially attributed to heparin anaphylaxis. She received maximum medical management but presented 6 months later to our institution with a secondary transient ischemic attack. Surgical options for the case were discussed amongst a multidisciplinary team. Transfemoral and transradial stenting were deemed non-viable due to the tortuous nature of the CCA. Repeat CEA under general anesthesia was deemed risk-prohibitive from a cardiac risk perspective. For these reasons, the patient was offered transcarotid artery revascularization (TCAR) under regional anesthesia. Intraoperatively, the “sheath stopper” was removed from the TCAR device, allowing the sheath to be advanced to 6 cm, effectively removing the tortuous component of the CCA. Flow reversal was established, and the operation proceeded in the standard fashion without neurologic change. The patient has remained on dual antiplatelet therapy and completed 2-year follow-up without evidence of restenosis, access site complication, or repeat neurologic event. This case demonstrates the potential applicability of TCAR to benefit a subset of patients who previously lacked a surgical option due to anatomical constraints. |
