Cervical Vertebral Artery to Facial Branch External Carotid Artery Bypass: 2-Dimensional Operative Video

External carotid-vertebral artery anastomosis for vertebrobasilar insufficiency.

Two patients with previous brain stem infarction and current symptoms of vascular insufficiency in the basilar circulation had evidence of vertebral artery occlusive disease. Angiography demonstrated ostial stenosis of the dominant right vertebral artery and retrograde flow down the left vertebral artery to the level of the transverse process of C2 in the first case and to the level of a severe...

Carotid and Vertebral Artery Dissection

cervical neurinoma encasing vertebral artery

our case was a 48-year-old man with cervical pain radiatingto the upper limbs. imaging showed an intradural tumor with extradural component encasing the vertebral artery.thetumor diagnosed asa neurinomaand had been removed surgically.the post operationmagnetic resonance imagingshowed that the tumor was completely removed andthe vertebral arterywas intact at theentire length.the goal of surgery ...

Cervical Carotid Artery

Background and Purpose A model for cerebral ischemia that requires injection of emboli into the internal carotid artery of the rabbit is commonly used. However, in our experience we have found the anatomy of the cervical carotid to be highly variable. If not appreciated, this may result in unexpectedly high variability in the severity of ischemic injury. We undertook this experimental protocol ...

Persistent primitive trigeminal artery associated with monocular blindness and external carotid-vertebral artery anastomosis

In this paper, we present 2 rare cases of persistent embryonic anastomoses. In one case, the patient presented with persistent trigeminal artery along with multiple foci of cerebral infarction as well as central retinal artery thrombosis. In the other case, the patient had direct anastomosis of the vertebral artery with ipsilateral external carotid artery as well as pontine infarction, aneurysm...
