Vascular anatomical variants found in the VH Dissector Pro software. Descriptive anatomical study

Abstract

Introduction With advances in technology over the past decades, reductions in teaching time, increasing class sizes, and increasing costs of cadaver‐based instruction, computer‐ based learning resources are used every increasingly in anatomy curricula to encourage student learning, and its use has been found to increase anatomy teaching, enhance independent learning, problem solving, and provide flexibility. Methods Using the VH Dissector Pro software version 6.0.16, a group of researchers through dissection tools reached the vascular planes of the cadaver in all body regions, in which the presence of some type of arterial vascular variant was searched. Results After having carried out the search in the VH Dissector Pro software version 6.0.16, it was found that in the upper limbs the deep brachial artery presented its origin at the level of the third portion of the right axillary artery and the left subscapular artery. An accessory renal artery was found bilaterally in the abdominal region. In the pelvic region, an origin was found bilaterally at the level of the posterior trunk of the internal iliac of the obturator artery. All these findings were found after analyzing all the body regions of the cadaver in the arterial vascular plane. Conclusion The knowledge of normal anatomy and anatomical variants is of great importance for anatomists who teach in different careers in the health area, as well as for clinical professionals who could find this type of variations both in diagnostic processes and surgical. By presenting this knowledge they will be able to transmit and differentiate normality versus the presence of anatomical variants that not only can be in cadavers, in imaging samples but could also be present in virtual anatomy. In addition, this study leaves the concern of analyzing other systems that could also present some other anatomical variant.
