Summary
Understanding anatomical variations of the saphenofemoral junction (SFJ) is crucial for safe varicose vein surgery. Documenting these variations helps prevent inadequate surgical outcomes in patients with primary varicose veins.
Area of Science:
- Vascular anatomy
- Surgical anatomy
- Phlebology
Background:
- The saphenofemoral junction (SFJ) is a critical area in vascular surgery.
- Variations in SFJ anatomy can impact surgical outcomes for varicose veins.
Purpose of the Study:
- To document the detailed surgical anatomy of the saphenofemoral junction (SFJ).
- To identify and record anatomical variations relevant to varicose vein treatment.
Main Methods:
- Diagrammatic recording of SFJ anatomy during 2089 groin dissections for primary varicose veins.
- Analysis of tributary number, bifid systems, junctional tributaries, and external pudendal artery (EPA) relationship to the long saphenous vein (LSV).
Main Results:
- 18.1% of LSVs were bifid.
- Tributary numbers ranged from one to ten.
- The EPA crossed anterior to the LSV in 16.8% of cases.
- Complex anatomical variations were observed, particularly with bifid LSVs and EPA positioning.
Conclusions:
- Comprehensive knowledge of SFJ anatomical variations is essential for safe and effective management of varicose veins.
- Failure to recognize these variations can lead to suboptimal primary varicose vein surgery.
