Couldwell, William T. | Submandibular-infratemporal interpositional carotid artery bypass for cranial base tumors and giant aneurysms | Cerebral revascularization is an important strategy in the surgical management of some complex cranial base tumors and unclippable aneurysms. A highflow bypass may be necessary in planned carotid occlusion or sacrifice. The cervical-to-supraclinoid internal carotid artery bypass or cervical carotid-... | Internal carotid artery; Cranial base tumors; Giant aneurysms; Interpositional bypass; Surgical approach; Radial artery; Revascularization; Saphenous vein; Submandibular infratemporal bypass | 2006 |

Couldwell, William T. | Surgical approaches for resection of vestibular schwannomas: Translabyrinthine, retrosigmoid, and middle fossa approaches | Surgical removal remains one of the key treatment modalities for vestibular schwannomas. A team approach between a neurotologist and a neurosurgeon offers the patient the expertise of both specialties and maximizes the chances for an optimal outcome. Vestibular schwannomas can typically be resected ... | | 2012-01-01 |
