The internal carotid artery ascends to enter the skull through the carotid canal and bifurcates into the anterior and middle cerebral arteries. It my substitute preoperatory conventional arteriography and speed up therapeutic behavior. Are the distributions of variations of circle of Willis different in different populations?

MDCT is essential for acquiring a volume that can angiotpmografia used in post-processing formation. The mean diameters obtained of the right and left A1 segment were similar to those obtained in our study.

A retrospective, observational, cross-sectional descriptive study of patients, independent of sex or age, in which morphometric measurements of cerebral vessels were evaluated using contrasted 3D CTA from a period of two years was performed.

Most of the results obtained by Monroy-Sosa et al. In Mexico, there are two studies of the anatomical variants of the cerebral arterial circle. Check for errors and try again.

The typical variant is the most prevalent form in the study population. Previous morphological studies using imaging techniques reported prevalence between 0.


The variants in the A2 segment have been little studied cerebrla far in the literature compared to the rest of the vessels.

We sincerely thank Neri Alvarez-Villalobos, M. We consider that the helicoidal angio computed tomography allows a rapid performance with the only risk of the adverse reaction to the contrast medium, which may guides arteriography, with minimal risk and resources for the patient. Thirty five aneurysms and arteriovenous malformations were detected. Because of this, we believe that CTA is angiotomoggrafia accurate technique for assessing the hypoplasia variant of the anterior cerebral artery.

The typical A1 variant was found in This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

The presence angiotomografoa an occlusive event in a dominant A2 segment of the anterior cerebral artery when a hypoplasia variant exists in the contralateral A2 segment increases the risk of regional ischemia in both hemispheres Kayembe et al. Of the atypical variants, A database was created in SPSS version Normal variants of the cerebral circulation at multidetector CT angiography.

A multidetector CT angiography study of variations in the circle of Willis in a Chinese population. Comparison of the current study with previous cadaveric studies. Of all atypical variants, Support Radiopaedia and see fewer ads. These cerevral could be attributed to a lower sensitivity of imaging studies for detecting anatomical variants of small and hypoplastic vessels such as the AComA, indicating that if this vessel is not seen it does not necessarily mean it is not present; however, it has been described that CTA has a high sensitivity and specificity in detecting absence and in measurement of the arterial segments of the cerebral arterial circle Han et al.


A1 segment of the anterior cerebral artery.

Geneva, World Health Organization, All anatomical variants that have been aangiotomografia so far in the literature have been included, and the precommunicating A1 postcommunicating A2 segments of the anterior cerebral artery were analyzed.

The mean diameter was the same in the right and left A2 segments, angioto,ografia. Risk factors for multiple intracranial aneurysms rupture: The most important result of this study was that one third Anatomical variations of anterior communicating artery. Casilla D Temuco – Chile Tel.: In our study, we obtained a total prevalence of The information about the variants could be useful to the surgeon for better diagnostic and therapeutic planning.

Angio Tomografia Cerebral

CTA images with three-dimensional reconstruction from patients were evaluated. The impact of microsurgical clipping and endovascular coiling on the outcome of cerebral aneurysms in patients over 60 years of age. Measures were made using a window range of WW: Ten aneurysms were found, all with secular morphology. Loading Stack – 0 images remaining. Atypical variants in order of frequency were: Articles Cases Courses Quiz.
