Abstract Background The local flaps, especially perforator and keystone flaps, are used as first-line treatment option in reconstruction of small tomoderate-sized defect of the extremity. However, the high complication rate associated with these flaps may hinder this usage. Methods This article reviews the technical and clinical aspect of using color duplex ultrasound )CDU) in the preoperative, intraoperative, and postoperative period for propeller and keystone flaps. Results CDU allows the surgeon to understand the anatomical aspect of the perforator such as the location, point of penetration on the deep fascia, subcutaneous pathway )axiality) and physiological aspect such as velocity and flow volume. Understanding and utilizing this information will allow accurate preoperative design, intraoperative decision making, and postoperative monitoring, leading to better outcome. Conclusion Carefully designed local perforator flaps based on anatomy and physiology using CDU will be a powerful armamentarium for reconstruction of the lower extremity.

Abstract Background Lateral thoracic flaps represent a precious source for partial and total breast reconstruction, in some cases as first option and in other cases as alternative of free flaps. This article describes the ultrasound (US)-based planning of the lateral thoracic wall perforator adipocutaneous flaps and it reports our experience on 52 consecutive flaps. Patients and Methods From November 2018 to May 2021, 52 consecutive lateral thoracic wall perforator flaps were performed using the US-based method for reconstruction of partial breast defects and total breast reconstruction. High-frequency US was performed in all cases prior to surgery to select the best perforator and design the flap. Results Of the 52 cases, 41 were lateral intercostal artery perforator flaps (78.8%), and 11 were thoracodorsal artery perforator (TDAP) flaps. Of the 11 TDAP flaps, 2 cases were based on the direct cutaneous branch. Moreover, in two other cases clinically scheduled for lateral thoracic perforator flaps due to the presence of an appropriate axillary roll, no suitable local/regional perforators were detected with the preoperative US examination and the latissimus dorsi myocutaneous flap was performed. Conclusion Preoperative planning of these flaps using US speeds the surgery and makes it easier and more efficient. Therefore, it is reasonable that the color duplex ultrasound is the operative surgeon's tool for mapping the lateral thoracic wall perforators and to appropriately plan each flap.

Background The main cause of severe chronic venous insufficiency is deep venous incompetence. Deep venous reconstructive surgeries are reserved for cases that do not show a good response to conservative therapies. Method We present the case of a 68-year-old man presenting with swelling, pain, and pigmentation in his left lower limb for 14 years and ulcers for 10 years. Descending venography identified a Kistner’s grade IV reflux in the deep vein of the left lower limb. Internal valvuloplasty was performed following Kistner’s method. Meanwhile, external wrapping with a 1-cm-wide polyester-urethane vascular patch was performed to strengthen the vein wall in the venospasm condition. Results Symptoms were immediately relieved postoperatively. Refractory ulcers healed five months after the procedure. At the six-month follow-up, color duplex ultrasound of the deep vein of the left lower limb showed no reflux in the proximal segment of the femoral vein. Conclusion Internal valvuloplasty combined with sleeve wrapping is feasible in the treatment of severe deep venous incompetence with good short-term results.
