Objective:
To evaluate the safety and outcomes of surgical revascularization for patients with symptomatic kinking of the internal carotid artery (ICA).
Methods:
Twenty-five consecutive patients presented with symptomatic kinking of the ICA and a history of transient ischemic attack (TIA) or stroke were prospectively enrolled in this study. All patients were treated with ICA transection and end-to-side reimplantation at the level of the carotid bulb. Patients were followed up for a median of 32 months.
Results:
There were no deaths or strokes within the 30 days of the treatment. No postprocedural thrombosis or narrowing of the ipsilateral ICA was observed. One (4%) patient had temporary recurrent nerve palsy, which was completely recovered at 4-week follow-up. One (4%) patient had a myocardial ischemic event. At the end of the 32-month follow-up, 1 (4%) patient developed ipsilateral minor stroke. No recurrent stenosis was detected by Doppler ultrasound.
Conclusion:
Surgical treatment for isolated, symptomatic kinking of the ICA and a history of TIA or stroke is safe, and the outcomes are acceptable.
