Summary
Nineteen major vena cava anomalies were found in patients undergoing abdominal vascular surgery. Understanding these variations is crucial for surgeons to prevent complications during operations.
Area of Science:
- Vascular Surgery
- Anatomy
- Embryology
Background:
- Abdominal vascular surgery requires detailed anatomical knowledge.
- Congenital anomalies of the vena cava can complicate surgical procedures.
Purpose of the Study:
- To classify and discuss major vena cava anomalies.
- To review embryologic origins and surgical implications of these variants.
Main Methods:
- Retrospective review of 19 cases with vena cava anomalies.
- Analysis of computed tomographic (CT) scans.
Main Results:
- Nineteen major anomalies of the vena cava or its branches were identified.
- Classification, embryologic development, and associated variants were detailed.
Conclusions:
- Familiarity with vena cava anomalies is essential for surgeons.
- Preoperative CT scan review aids in avoiding intraoperative complications.
