Background and Purpose Long-segmental thrombotic occlusion of the distal internal carotid artery (ICA) sparing the cervical segment proximally and the supraclinoid segment distally, which could be termed ’Carotid S occlusion’, has an unusual clinical presentation. However, endovascular management of this lesion is challenging. The purpose of our study is to report our endovascular treatment clinical experience of the disease.
Methods From March 2008 to June 2013, we could identify 14 patients (average age: 62.1, median age: 62, range: 50-79) with ‘Carotid S occlusion’, who underwent endovascular recanalization procedures. Patient’s clinical presentations were collected and the imaging findings also analyzed. The technical success rate, 24-hour and follow-up imaging outcome, and the clinical outcome using the 90-day mRS (modified Rankin scale) score were evaluated.
Results Patients presented with gradually progressing (n=8), fluctuating (n=3), transient ischemic attack (n=2) and stationary (n=1) symptoms. DWI showed internal and external border-zone lesions in six patients, only internal ICA border-zone lesions in three patients, and only external border-zone lesions in two patients. Underlying distal ICA stenosis was noted in 12 patients. The technical success rate was 92.8% (13/14). Luminal patency was noted in all patients (100%) after 24 hours and in nine of 10 (90%) on long-term follow-up (median: 6.5, average: 15.1, range: 1-39 months). A 90-day, good functional outcome (mRS≤2) was noted in 13 of 14 patients (92.8%).
Conclusions ‘Carotid S occlusion’ usually presented with border-zone infarction and endovascular management of the lesions was feasible. A relatively successful clinical outcome could be achieved after successful revascularization.
