Aortoduodenal fistula is a rare cause of gastrointestinal (GI) bleeding, and carries high morbidity and mortality even in modern practice. Cervical carcinoma is a major health threat among adult women, and its recurrence is not uncommon. ⋯ Prompt diagnosis and rapid treatment are critical in reducing mortality and morbidity. Although rare, metastatic carcinoma can lead to aortoenteric fistula.

Carotid endarterectomy (CEA) is associated with a risk of cerebral ischemia during carotid clamping, hence various cerebral protection strategies, including pharmacological management and routine or selective shunting, are commonly available. This study aimed to analyze the results of CEA with intraoperative electroencephalographic (EEG) monitoring to identify factors associated with EEG changes consistent with cerebral ischemia which needed shunting. ⋯ EEG was an excellent detector of cerebral ischemia and a valuable tool in guiding the need for shunting. Patients who were symptomatic or had a history of stroke, a contralateral carotid occlusion, or an ipsilateral moderate carotid stenosis were more prone to EEG changes consistent with cerebral ischemia. Surgeons should consider EEG changes during clamping as an effective criterion for selective shunting.
