Sapheno-Femoral Junction Aneurysm: Single Centre Experience With Technical Notes and Histological Analysis

Objective: An aneurysm is a localized dilation of a blood vessel, commonly referring to the arterial system, but venous aneurysms, especially in the lower limbs, are significant and often underreported vascular conditions. This study focuses on superficial venous aneurysms at the sapheno-femoral junction (SFJ), categorized as Type IA and IB. Materials and Methods: Eleven patients (5 females, 6 males; mean age 50 years) with venous masses were identified after negative hernia evaluations. Diagnosis was established through clinical examination and duplex ultrasound, confirming SFJ dilation with specific inclusion criteria. Surgical excision was performed, followed by follow-up assessments up to 5 years. Results: All patients underwent successful surgical excision. No major complications occurred, and all patients ambulated immediately post-surgery. Five years post-operation, there were no inguinal recurrences, and residual great saphenous vein remained patent and continent. Histopathological analysis revealed wall thinning, reduced smooth muscle and elastic fibers, and fibrous connective tissue predominance. Conclusion: Superficial venous aneurysms at the SFJ are rare but can be effectively managed through surgical excision. With appropriate diagnosis and intervention, the risk of complications is minimal, supporting the need for awareness and accurate classification in clinical practice.
