To provide brief overview of the development of cranial arterial anatomy.
To obtain a better understanding of some arterial anomalies.
To point out commonly encountered anatomial variatons that may have clinical significance.
In the embryonic period severeal developmental anomalies of the cerebral arteries can occur.
During embryogenesis the brain vascular system continuously adapts the supply of oxygen and other nutrients to the needs of the parenchyma.
These changes often deviate from normal pathway and produce various anatomic variations.
Discussion of cerebral arterial development begins with the formation of the six pairs of primitive brachial arch arteries that either regress or are subject to...
Imaging findings OR Procedure details
CT angiograms and MRI aniograms are used to illustrate development,
anatomy and variants of cerebral arteries.
Normal variations include fenestrations,
variants of the circle of Willis,
persistent carotid-basilar anastomoses,
and other vascular anomaliesinthe skull base. When assessing CT or MRI angiograms,
it is important to thinkabout normal variants,
and their clinical relevance,
particularly with respect to the risk of...
Understanding of cerebral arterial embryology is fundamental for anyone seriously involved in any field where neural vasculature plays a role.
Knowledge of the presence and clinical relevance of normal variants plays agreat role in surgical planning or assesing the risk of aneurysm formation.
