Abstract Body : Introduction and Objective

Renal arteries are vessels that play important physiological roles in the human body (WHITE et al., 2021). Consequently, anatomical variations in the renal vascular pattern, such as the number of arteries, their origin, and/or course, are common. Therefore, the purpose of this study is to conduct a descriptive and observational investigation of the renal arterial vascular pattern observed in the right kidney of a male cadaver and compare these findings with those documented in the literature.



Materials and Methods

A descriptive and observational study of the renal vascular anatomy of the right kidney from an unclaimed male cadaver, preserved in 10% formaldehyde and aged approximately 40 years, dissected in the abdominal region, was conducted. Red acrylic dye was utilized to highlight vascular structures, which were subsequently photographed.


Results

The dissection displayed an anatomical variation in the arterial vascular supply to the right kidney. Furthermore, three accessory renal arteries observed during the cadaver's abdominal dissection originated from the abdominal aorta, which, according to Tardo et al. (2017), is the most common site of origin. This finding is consistent with the study conducted by Barrios et al. (2023), where out of a total of 16 renal structures, arterial variations were more prevalent on the right side (64.3%) than on the left side (35.7%).



Conclusion

This study observed an anatomical variation in the arterial vascularization of the right kidney, featuring two lower polar renal arteries and one upper polar renal artery. The pattern aligns with existing literature, as the arterial variation pattern, predominantly on the right side, includes renal vascular structures emerging from the abdominal portion of the aorta.



Significance/Implication

Understanding the normalcy and anatomical variations in human vascularization is crucial for performing operative procedures in the retroperitoneal region of the abdomen.
