Ischemic symptoms caused by traumatic vertebral artery dissection after cervical maneuvers are treated medically and surgically. This is a report of the infrequently documented occipital to vertebral artery bypass to stop the transient ischemic attacks following traumatic vertebral artery dissection. ⋯ A bypass from the occipital artery to the atlas loop of the vertebral artery is an effective procedure for traumatic extracranial vertebral artery dissection with ischemic symptoms.

There is a lack of precise methods for predicting the risk of aneurysm rupture. Therefore, prophylactic treatment is used, which leads to unnecessary potential complications. A new modality enabling a more accurate risk assessment is needed. Optical coherence tomography (OCT) is a new-generation imaging technology that has astonishing resolution for vascular imaging. In this study, OCT was used for the evaluation of intracranial aneurysms. ⋯ OCT is the most precise imaging modality because it provides detailed information regarding the aneurysm structures, thus enabling more distinct insight into the vascular construction of intracranial aneurysms.

To investigate construction of an aneurysm on a curved vascular segment of a carotid siphon model for testing endovascular devices. ⋯ The carotid siphon model in vivo can simulate well the geometry of the human carotid siphon segment and can be used to test endovascular devices for interventions.
