Objective: Saphenous varicose veins can be accomplished by various operative techniques that result in stripping, ablation, or ligation of the venous reflux section. Great saphenous vein (GSV) stripping is one of the standard operations for varicose veins to eliminate reflux of the sapheno-femoral junction. The goal of any treatment regimen is to eliminate the junctional varicose reflux to control congestive dysfunction. Endovenous laser ablation (EVLA) is safe and effective with less postoperative pain, bleeding, and peripheral nerve damage than open surgery. In this study, a patient with severe progression of primary saphenous varicose veins is presented. We report the outcome of combined surgical strategy and perioperative treatment for extremely swollen varicose veins of the lower limbs to improve leg symptoms and congestion and/or promote skin ulcer healing. Materials and Methods: The subjects included 42 patients (51 limbs) who underwent EVLA with stripping. The patients comprised 24 males and 18 females, who presented a maximum GSV diameter >15 mm. The Clinical-Etiological-Anatomic-Pathophysiologic classification identified 9, 20, 9, 2, 6, and 5 limbs with C2, C3, C4a, C4b, C5, and C6, respectively, among the 42 patients. Results: EVLA was used to treat GSV with a mean length of 16.1±2.8 cm. The mean of the maximum GSV diameter was 16.8±3.2 mm (14.6-21.8 mm). The preoperative visual analog scale (VAS) score was 82.1±12.1. After operation, the VAS gradually deteriorated to 31.3±17.9 (p<0.0001), 2.8±3.6 (p<0.0001), and 1.2±1.8 (p<0.0001) in 7 days, 1 month, and 3 months, respectively. Conclusion: We obtained a satisfactory outcome from our combined strategy and perioperative treatment for extremely swollen saphenous varicose veins. This approach may show the possibility that lower saphenous varicose veins can induce cosmetic and minimally invasive ameliorated intervention to avoid late-phase incompetent perforating veins.

A venous aneurysm is a relatively rare disease defined by cystic vasodilated lesions in a general vein. Popliteal venous aneurysm (PVA) is a rare clinical entity, and the first signs may be a thromboembolic event. They can cause potentially life-threatening diseases, such as pulmonary embolism and deep venous thrombosis. A left-sided inferior vena cava (IVC) is a common anomaly associated with venous thrombus, resulting in anatomical variations in the venous return from the lower limbs. The general vascular malformation of PVA and left-sided IVC should also be preoperatively understood because of the unpredictable risk of thromboembolic complications.

The treatment tactics for subclavian artery occlusion include the more commonly used endovascular therapy rather than surgical intervention. We present a case of a 61-year-old woman with dialysis-dependent chronic renal failure who experienced left finger necrosis in the left upper extremity. To salvage the limb, we performed femoro-axillary (fem-ax) artery bypass using an autologous saphenous vein graft. However, 10 months later, she experienced coldness in the left forearm. Angiography revealed chronic total occlusion of the venous bypass. Despite emergent thrombectomy, redo fem-ax artery bypass operation was performed using a prosthetic graft. Upper limb salvage can be achieved by fem-ax artery retrograde bypass.
