This method is used in combination with sclerotherapy ablation for best results. The most common complication involves skin blistering from dressing abrasions and adhesive tape. Wound infections may occur. Less commonly, small sensory nerves can be injured leading to areas of anesthesia and less commonly hyperesthesia. A rare injury could result from common peroneal nerve injury. The common peroneal nerve is commonly located just medial to the biceps femoris tendon and near the fibular head. Injury to this nerve can cause sensory loss or foot drop. When planning microphlebectomy, care or avoidance of this region is recommended [2]. Lower Extremity Chronic Venous Disease Variant 3: Venous leg ulcer. Initial diagnosis. Catheter Venography Iliac Veins Catheter-directed venography of the iliac veins has been described as the next step in diagnosis after CTV/MRV has characterized an occlusion or stenosis [9]. Venography has been criticized for low sensitivity for identifying critical lesions in the iliac vein [41]. Venographic findings can be grouped into normal, stenosis, and occlusion [8]. Catheter Venography Lower Extremity Digital subtraction ascending venography has been described as the next step in diagnosis after CTV or MRV has characterized an occlusion or stenosis [9]. Catheter-directed venography of the lower extremity is used mainly as part of a procedure in which treatment is planned for post-thrombotic and nonthrombotic obstruction of the iliac veins and much less often for post-thrombotic femoral veins. CTV Lower Extremity CTV of the lower extremity has not been cited as a first-line examination. However, it is helpful after duplex US in evaluation for occlusion, stenosis, collaterals, post-thrombotic changes, and axial transformation of the profunda vein [8]. Further highlighting the importance of CTV before intervention is the high rate of recurrence 2 years postintervention (15%-35%).
