AMA 482-107

Pdf Summary

The case report discusses a 57-year-old man who presented with worsening varicose veins in his left lower extremity, specifically in the left lateral thigh. Imaging revealed the absence of the left external iliac and common femoral veins, with drainage provided by the great saphenous vein. The patient's history suggested a possible iatrogenic injury as a newborn. Despite valvular insufficiency, the surgeon decided against ablating the great saphenous vein due to its role in draining the leg. The patient underwent microincision phlebectomies for his varicose veins instead. This case highlighted the importance of identifying rare abnormalities in venous duplex studies for appropriate treatment decisions. The findings demonstrated the significance of the great saphenous vein reflux, prompting a decision to avoid its ablation. The report aimed to bring awareness to such unique cases and their implications for vascular ultrasound practice and patient care.
