Extra- to intracranial arterial anastomoses in therapeutic embolization: recognition and role. 1980

H S Ahn, and C W Kerber, and Z L Deeb

Anastomoses from extra- to intracranial vessels have been shown in normal patients and, more commonly, in patients with arteriosclerotic occlusive disease, arteriovenous malformation, and postligation of the carotid artery. These channels may be of clinical importance during therapeutic embolization and probably account for two cases of complication, posterior fossa strokes that occurred after blockage of occipital arteries. By identifying these channels and then monitoring the ever-decreasing vessel acceptance of contrast agent and emboli, patient safety may be enhanced.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009333	Neck	The part of a human or animal body connecting the HEAD to the rest of the body.	Necks

D002548	Cerebral Revascularization	Microsurgical revascularization to improve intracranial circulation. It usually involves joining the extracranial circulation to the intracranial circulation but may include extracranial revascularization (e.g., subclavian-vertebral artery bypass, subclavian-external carotid artery bypass). It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularized tissue to the surface of the brain.
