how many aortic arches do humans have


Left ventricular mass is a well-established predictor of possible cardiovascular events, and can continue to increase in normotensive patients who have undergone aortic coarctation repair. Sociedad Española de Neurología. Turbulence significantly increases pressure and fluid shear stress in an aortic aneurysm model under resting and exercise flow conditions. CMR of the aorta. Taking the application of phylogenetic analysis into account, it should be emphasized that it is not possible to approach the patient with aoetic coarctation, whether a child or adult, as the carrier of a "simple" congenital malformation. Subscribe to our newsletter. The LSA, in charge of supplying the left upper limb and some thoracic structures, had an average of 8. CO;2- Medline.

Variaciones anatómicas del arco aórtico en una muestra de población colombiana. Manuel Rojas 1. Wilson Muete 1. Yobanny Quijano 1. The aortic arch AA is the origin of the vascular structures that supply the upper limbs and the brain. Up to eight different types of distributions have been described with clinical and surgical implications. To determine the frequency of anatomical variations of the AA, and to establish the vascular diameters of its branches in a sample of Colombian population.

A descriptive cross-sectional study was conducted by dissecting 35 cervicothoracic grafts obtained through convenience sampling. The distribution of AA was similar to that reported in Colombia and other countries, being Type I the most frequent, followed by Type II or bovine arch. The vascular diameters showed results similar to those obtained in the Colombian population, but evidently lower than those reported in international studies.

Although the frequency of AA types in the Colombian population happen to be similar to those in other countries, the vascular diameters in Colombia are smaller. El arco aórtico AA es el origen de estructuras vasculares que suplen los miembros superiores y el encéfalo. The aortic artery is a high caliber vessel which originates in the vascular ring of the aortic valve and descends until dividing into common iliac arteries in the sacral promontory 12.

Its histological structure, to which various pathological processes have been associated, has antiatherosclerotic, antithrombotic, as well as capacitor, conductor and pumping how many aortic arches do humans have 2. The aorta presents subdivisions, determined by anatomical relationships, such as the aortic arch AAwhich originates in the posterior portion of the second right sternocostal joint and ends behind the second left sternocostal joint 1.

The vascular structures that supply the upper limbs and the brain originate in the AA: the brachiocephalic artery trunk, the left common carotid artery and the left subclavian artery 2. According to different investigations, the frequency of this pattern is The remaining structures correspond to anatomical variations, most likely caused by gestational processes, and are related to the arrangement of the primitive vascular branches within AA 9. Some of these variations usually have how many aortic arches do humans have on different pathological processes, surgical approaches and complications Similarly, the existence of these variations has become a risk factor for the development of aortic disease 4.

Therefore, knowing these vascular distributions is highly relevant for diagnosing and planning open and endovascular surgical approaches to the aortic disease 41011leading to the need for deeper knowledge on the frequency of anatomical variations of blood vessels originating in the AA, as well as on the calibers of each vascular structure in a sample of Colombian population.

Plastrons with cervical congenital malformations, evidence of cervical trauma, cervical tumor processes or anatomical alterations caused by manipulation after removal of the corpse were casual cittГ  alta considered. The dissection process was performed by removing fatty tissue and the pericardium covering the ascending aorta, the aortic arch and the blood vessels in the aorta.

Then, the vascular diameters of the aortic arch were measured how many aortic arches do humans have a digital caliper Figure 1. Throughout the process, photographic evidence was taken using a Nikon 1 J5 camera. Source: Own elaboration based on the data obtained in the study. What is the date in 35 days 1 Measurement of vascular diameters and intervascular distances.

After the observations and measurements, the information was tabulated in Microsoft Excel based on Natsis et al. The data regarding the vascular measurements were tabulated and cataloged according to the classification of Herrera et al. Table 1 Representation of anatomical variations. The data obtained from the classification of anatomical variations were treated through absolute and relative frequencies for the corresponding comparison against other national and international studies, while the evidences obtained from the measurement of vascular diameters were handled through mean and standard deviations.

This research was developed in strict compliance with the criteria for performing medical-legal autopsies as specified in Decree of The principles of the Declaration ofHelsinki 13 were also followed, guaranteeing a respectful treatment of the anatomical parts, and keeping the confidentiality, dignity and integrity of the deceased person.

Likewise, according to the parameters of Resolution of of the Ministry of Health 14the research was approved by the Institutional Ethics Committee. Figure 2 Aortic arch Type I. Figure 3 Aortic arch Type II. Figure 5 Aortic arch Type V. The mean diameter of AA before the origin of the first blood vessel was The diameter of the brachiocephalic trunk BCT was 9. Table 2 Distribution of anatomical variations of the how many aortic arches do humans have arch.

Table 3 Mean diameter measurements of how many aortic arches do humans have main blood vessels in millimeters. The study of the anatomical variations of the AA is of great importance for morphological research due to its application in the clinical and surgical approach to the aortic disease. Different morphological patterns of this structure have been described; the first one is Type I or usual pattern, which consists of the emergence of three vascular branches known as arterial brachiocephalic trunk BCTleft common carotid artery LCCA and left subclavian artery LSA.

According to the literature, the prevalence of this anatomical distribution is In this study, this was the second most frequent distribution with AA Type II has proven to be a risk factor for premature aortic disease and, therefore, knowing how frequent it is among the general population could help determining the probability of acute aortic syndromes in patients with this abnormality 4.

This pattern has been reported with frequencies between 0. Although this what is causal reasoning in speech is beyond the aforementioned range, it is very close to that reported by Herrera et al. This variation of AA may be a population preference, which would be relevant for the clinical and surgical approach to aortic disease. Regarding Type IV AA, there is a great discrepancy between population studies around the world because some authors use this category to include all anatomical variations that do not fit into any of the first three groups, while others such as Natsis et al.

According to the first approach, Type IV anatomical variations have a frequency of 0. Table 4 Distribution of anatomical variations of the aortic arch in the world population and in this study. To provide a more detailed anatomical description of Type IV variations, a sub-classification was done based on Natsis et al. Natsis et al. Although both studies found only one case of each type, the frequencies differ from each other because of the population sample considered for each study, which does not rule out the low occurrence of these anatomical variations in the general population.

The analysis of blood vessel diameters is also of great importance not only at the morphological but also at the surgical level, during the preoperative assessment of aortic disease for endovascular or open intervention 8. While the diameter of AA in the Colombian population described by Herrera et al. No other is nosql a database study measured AA Table 5.

Table 5 Diameter measurements in millimeters of the main blood vessels in the world population and this study. In other studies, BTC had a minimum diameter of 9. In this research, a diameter of 9. The measures taken in this study and in Herrera et al. How many aortic arches do humans have LCCA is responsible for supplying oxygenated blood to the structures of the neck and a large part of the brain 9.

The diameter of this artery was 5. The LSA, how many aortic arches do humans have charge of supplying the left upper limb and some thoracic structures, had an average of 8. Although the measurement of LVA is part of the study of anatomical variations, it was not reported in any of the works consulted, what is systematic biography makes comparing results impossible.

In this study, the diameter of such artery had a mean of 3. The TIA, one of the least described arteries in morphological how many aortic arches do humans have on AA, was not reported in the works consulted, which hinders comparison. In this research, the only case found had a diameter of 6. The distribution of the aortic arches in the sample studied how many aortic arches do humans have frequencies similar to those shown in previous how many aortic arches do humans have on local and world population, being AA Type I the most frequent pattern.

AA Type II or bovine arch had a lower frequency than all what is a role model meaning studies reviewed. Given the proven association between its presence and a higher incidence of aortic disease, this finding could mean that the Colombian population has a lower risk of contracting pathologies related to this anatomical variant 16 - This could be a major particularity of the Colombian population in relation to endovascular and open surgery, especially when planning highly complex surgical procedures.

Type IV AA and its subdivisions were found to be less frequent compared to the other groups. It should be noted that two rare blood vessels were described in this group: the right aberrant what is the meaning of the term dominant hemisphere artery RASA and the thyroid ima artery TIA ; therefore, doctors and surgeons are advised to be attentive how many aortic arches do humans have the presence of these structures in Colombian patients.

In general, the diameters of blood vessels from the AA had lower mean values than those reported in studies from other countries. This is most likely due to anthropometric differences in height and weight, which in the Colombian population tend to be lower than in the rest of the world 11 The presence of smaller diameters in the vessels derived from AA increases the risk of vascular disease by 6.
