Summary
A rare persistent sciatic artery was found in a 60-year-old man, connecting the iliac artery to the popliteal artery. This anatomical variation shows the sciatic artery joining the femoral artery
Area of Science:
- Vascular anatomy
- Human embryology
- Surgical anatomy
Background:
- The sciatic artery is a fetal vessel that typically atrophies during development.
- Persistence of the sciatic artery is a rare congenital anomaly.
Observation:
- A 60-year-old Japanese male presented with a persistent sciatic artery.
- The right persistent sciatic artery measured 5 mm in diameter.
- It connected the internal iliac artery proximally and the popliteal artery distally.
Findings:
- The terminal portion of the femoral artery (3 mm in diameter) connected to the persistent sciatic artery in the popliteal fossa.
- This case illustrates a complete type of persistent sciatic artery.
Implications:
- Understanding this anomaly is crucial for accurate diagnosis and treatment of vascular pathologies in the lower limb.
- Knowledge of persistent sciatic artery variations aids surgeons in avoiding complications during vascular procedures.
- This case contributes to the literature on rare vascular variations and their clinical significance.
