[Phlebographic observations on the morphology and function of the femoral vein and its valves]

Area of Science:

• Vascular anatomy and physiology
• Medical imaging techniques

Background:

• The femoral vein and its valves are crucial for lower limb venous return.
• Understanding their normal and abnormal morphology is essential for diagnosing venous diseases.

Purpose of the Study:

• To analyze and compare the morphology and function of the femoral vein and its valves.
• To establish diagnostic criteria for normal and abnormal femoral veins and valves.
• To classify types of femoral valvular incompetence and evaluate phlebography's diagnostic utility.

Main Methods:

• Ascending and descending phlebography were performed on 334 cases (414 lower limbs).
• Statistical analysis was used to establish diagnostic criteria.
• Morphological and functional characteristics were compared between normal and abnormal groups.

Main Results:

• Diagnostic criteria for normal and abnormal femoral veins and valves were established.
• Three distinct types of femoral valvular incompetence were identified and proposed.
• The study demonstrated the effectiveness of ascending and descending phlebography in diagnosing femoral valve abnormalities.

Conclusions:

• Ascending and descending phlebography are valuable tools for diagnosing femoral vein and valve conditions.
• The proposed classification of femoral valvular incompetence aids in diagnosis and understanding.
• Established diagnostic criteria enhance the accuracy of evaluating femoral vein and valve morphology and function.
