PURPOSE Our goal was to analyze the anatomic similarity between the duplicated middle
cerebral artery (MCA) and the accessory MCA and their relationship to the early branches of …

A series of 455 bilateral carotid angiographies included 14 accessory middle cerebral
arteries (Acc MCAs) and seven duplication of middle cerebral arteries (Dup-MCAs). The …

BACKGROUND: An aplastic or twiglike middle cerebral artery (Ap/T-MCA) is an extremely
rare congenital anomaly related to interference in the normal embryonic development of the …

The existence of the accessory middle cerebral artery (AMCA) is a rare anatomical variation
with an estimated incidence of 0.31%. The embryological development of this artery is …

Fourteen accessory middle cerebral arteries demonstrated on angiography were reviewed
relative to the pertinent literature. The anomalous vessel follows a fairly constant pattern in …

The middle cerebral artery has been noted to demonstrate anomalies less frequently than
the other major intracranial arteries. The cerebral angiograms and brief case histories of 7 …

Introduction Fenestration, early bifurcation, and duplication of the posterior cerebral artery
(PCA) and the so-called hyperplastic anterior choroidal artery (AChA), considered a …

Twenty hemispheres were perfused with colored silicone and the MCA was dissected. For
the cortical branches, the diameter, length, presence, duplication and origins were noted …

Although many cerebral vascular anomalies are widely recognized, others are less well
known or unclassified. Accessory middle cerebral artery (MCA) and duplicated MCA are …

The middle cerebral artery supplies the largest area with the most complex branching of any
of the intracerebral vessels. The anatomy of the middle cerebral artery, in relation to …
