Anatomy Rare origin and course of left testicular artery associated with phrenico-adreno-gastric trunk

Introduction The testes receive its blood supply from the testicular arteries. Variations in origin, number and course of these vessels are often reported. However, in the present case we discuss unusual origin and course of left testicular artery, its embryology and clinical significance. Case report A rare case of an unusual origin and course of left testicular artery associated with other vascular anomalies was observed in an 88years-old Japanese male cadaver. The artery originated as a continuation of the phrenicoadrenogastric trunk from the right side and shifted to the left to give dual arterial supply to the left testes. Conclusion Knowledge of this novel anatomical variation of the testicular arteries and great vessels of the upper abdomen is of clinical importance for urologists, radiologists, and surgeons undertaking routine procedures involving regions supplied by these vessels.
