Abstract
BACKGROUND: Reconstruction of the internal carotid artery (ICA) is an operative challenge for lesions involving the lateral skull base because of excessive blood loss, intraoperative cranial nerve injury, and difficulties in cerebral protection. METHODS: Between January 2010 and October 2014, 9 patients with vascular lesions at the lateral skull base were treated with a "pre-reconstruction" technique, which means reconstruction of the ICA in advance of excising the lesions. RESULTS: All operations were technically successful with no mortality or strokes. The mean blood loss was 921 ± 210 mL. The mean total clamping time was 18 ± 5 minutes. Among the 5 patients without invasion of specific cranial nerves, no long-term sequelae occurred during the follow-up period ranging from 11 to 54 months. CONCLUSION: With less blood loss, slighter cranial nerve injuries, and shorter clamping time, the "pre-reconstruction" technique was safe and effective for the treatment of vascular lesions at the lateral skull base.
