Background: The twisted carotid artery is a variant, in which the internal carotid artery (ICA) courses medially to the external carotid artery. Due to the sparse descriptions in the literature, we, here, report our experience with cases of carotid endarterectomy (CEA) for twisted carotid artery and its clinical features. Methods: Fifty-seven consecutive CEA-treated patients were evaluated, and the twist angle was measured on the source images of axial slices of computed tomography angiography (CTA). Results: Eight male patients (14.2%) demonstrated a twisted right ICA (mean age, 77.0 ± 2.6 years; and mean stenosis, 66.9% ± 19.9%). The mean twist angle was 30.1° ± 17.9°, while the normal ICA is angled at −23.0° ± 12.3°. No statistical differences in the distribution of coexisting diseases were found between the normal and twisted ICA cases. CEA was successfully performed with the correction of the carotid position in all cases; however, significant position correction was not observed in the postoperative evaluation. Right-side dominancy (P = 0.045) and prolonged clamping time (P = 0.053) were observed in the twisted cases. Conclusion: Twisted ICA was preferentially found in the right ICA and men. CEA of the twisted ICA was safely performed with appropriate head rotation and wider longitudinal skin incision than usual without a significant increase in the operative time. CTA is useful for preoperative evaluation. This specific variation should be considered by the neurosurgeon involved in the evaluation and treatment of carotid stenoses.

Distal Flow

Objectives This study describes an alternative carotid bifurcation endarterectomy technique in which the external carotid artery is used as a suture patch. Methods Charts of ten patients with atherosclerotic carotid stenosis that were treated using the neobulb technique between 2002 and 2019 were reviewed. Results No major surgical adverse event was observed in the postoperative assessments. No postoperative common or internal carotid stenosis was observed in the mid- or long-term follow-up. Conclusions The neobulb technique allows carotid endarterectomy closure without a synthetic or venous patch, using the external carotid artery as an autologous patch, while preserving distal flow into the external carotid artery branches.

Abstract Our experiences with a patient who developed recurrent hemispheric transient ischemic attacks 3 1/2 years after ipsilateral carotid endarterectomy are described. Although repeat arteriography demonstrated smooth and unobstructed common and internal carotid arteries and a normal intracranial circulation, there was complete occlusion of the external carotid artery at its origin, which appeared as a stump or diverticulum at the origin of the internal carotid artery. This stump was filled with atherothrombotic debris and served as a source of emboli to the adjacent and patent internal carotid artery. Excision of the stump effected complete relief of the recurrent ischemic symptoms. The pernicious potential of an external carotid obstruction when adjacent to a patent internal carotid artery should be recognized. To prevent this avoidable complication of carotid endarterectomy, we recommend that the origin of the external carotid artery be treated with the same standards of technical perfection as those customarily applied to the internal and common carotid arteries during this procedure.
