Summary
Accessory renal arteries, variations of the main renal arteries, were found in 21.1% of human fetuses. These anatomical variations occurred as single, double, or triple arteries, often originating from the abdominal aorta.
Area of Science:
- Anatomy
- Embryology
- Vascular Biology
Context:
- Renal arteries are crucial for kidney function.
- Accessory renal arteries are anatomical variations that can impact surgical procedures and understanding of renal vasculature.
- Previous studies have documented variations, but a comprehensive analysis in a large fetal cohort is valuable.
Purpose:
- To investigate the prevalence and patterns of accessory renal arteries in human fetuses.
- To describe the origin, distribution, and relationship of accessory renal arteries to the renal pelvis and kidney segments.
Summary:
- Conventional anatomical methods were used to study 140 human fetuses.
- Accessory renal arteries were identified in 21.1% of fetuses, presenting as single (19.2%), double (2.1%), or triple (0.7%) variations.
- These arteries most frequently originated from the right abdominal aorta, predominantly in female fetuses, and supplied various kidney segments, often anterior to the renal pelvis.
Impact:
- Provides detailed anatomical data on accessory renal artery variations in a fetal population.
- Contributes to a better understanding of renal vascular development and potential implications for urological and vascular surgery.
- Highlights the importance of recognizing these variations during medical imaging and surgical planning.
