    Abstract:
    OBJECTIVE: To evaluate the clinical results and factors related to the resolution of preoperative cranial neuropathy after internal carotid artery ligation with high-flow bypass in patients with symptomatic large or giant cavernous carotid aneurysms. METHODS: This study included 18 consecutive patients (15 women) with cranial neuropathy. All patients underwent therapeutic internal carotid artery ligation with high-flow bypass using a radial artery graft. Patient demographics, duration of symptoms, clinical outcomes, complications, and radiographic findings were retrospectively analyzed. The mean follow-up period was 31.0 months (range: 3-74 months). RESULTS: Patients' mean age was 66.6 years, and the mean aneurysm size was 23.7 mm. Six patients (33%) had partially thrombosed aneurysms. Preoperatively, 16 (89%) and 8 (44%) patients presented with ophthalmoplegia and facial pain, respectively. Bypass patency was confirmed in 15 patients (83%), and obliteration of the aneurysm was confirmed in all patients at the final follow-up. Preoperative ophthalmoplegia resolved in 10 patients (63%), and trigeminal pain resolved in all patients. Postoperative resolution of patients' ophthalmoplegia was significantly associated with age (P = 0.044), symptom duration before treatment (P = 0.042), and the degree of ophthalmoplegia (P = 0.046). The degree of postoperative residual ophthalmoplegia was positively correlated with the duration of ophthalmoplegia from onset to surgery (r = 0.619; P = 0.011). Preoperative trigeminal pain resolved regardless of the preoperative duration of this symptom in all patients. CONCLUSIONS: Early treatment is recommended when treating large or giant cavernous carotid aneurysms with cranial neuropathy. Complete resolution is possible in younger patients with partial neuropathy.
