The prevailing anatomical variant in most studies has been the typical form of the anterior cerebral artery- anterior communicating artery
complex with a range between 14.
3) The two anterior cerebral arteries frequently differ in size at their origin and the larger one reinforces the other through anterior communicating artery
KEY WORDS: Posterior communicating artery
, Circle of Willis, Aplasia, Hypoplasia.
7-13] On the other hand, on the basis of clinical tests carried out in patients with occlusion of the internal carotid artery and occlusion of the basilar artery, it was concluded that the increased risk of stroke exist in patients whose posterior communicating artery
diameter was < 0.
2 and 3) confirmed the presence of a large 2 x 1 cm aneurysm arising from the posterior communicating artery
and a smaller aneurysm arising from the middle cerebral artery.
Optochiasmal arachnoiditis following cotton wrapping of anterior communicating artery
aneurysm treated by surgical removal of granuloma.
compression of the nerve in the inter-penducular fossa by aneurysm of the posterior communicating artery
, which appears most prone to this disorder, or of the basilar, posterior cerebral or superior cerebellar arteries.
The right- and leftsided arteries then are connected by the anterior communicating artery
, which forms the anterior half of the circle of Willis, the system of arteries that nourishes and oxygenates the brain.
In 1%-2% of women, however, one uterine artery is hypoplastic, and a large communicating artery
connects the ovarian artery to the uterus.
Interestingly, the AV malformation was being fed by a communicating vessel from the posterior internal communicating artery
When location was examined as a risk factor, only aneurysms in the anterior communicating artery
(ACoA) and posterior communicating artery
(PCoA) were significantly more likely to be found among patients with ruptured aneurysms.
3) He noted that there was an underrepresented anterior communicating artery
aneurysms--could it be that aneurysms hemorrhage and was not included in the study?
