Lateral chest wall perforator flaps in partial breast reconstruction

Background Breast conserving surgery (BCS) has been a standard procedure for the treatment of breast cancer instead of mastectomy whenever possible. Lateral chest wall perforator flaps are one of the volume replacement techniques that participate in increasing the rate of BCS especially in small- to moderate-sized breasts with good cosmetic outcome. In this study, we tried to evaluate the outcome of those flaps as an oncoplastic procedure instead of the conventional flaps. Methods This study included 26 patients who underwent partial mastectomy with immediate reconstruction using lateral chest wall perforator flaps in the period from October 2019 to November 2020. The operative time, techniques, and complications were recorded. The cosmetic outcome was assessed 3 months post-radiation therapy through a questionnaire and photographic assessment. Results Lateral intercostal artery perforator (LICAP), lateral thoracic artery perforator (LTAP) and combined flaps were performed in 24, 1, and 1 patients, respectively. The mean operative time was 129.6 ± 13.2 min. The flap length ranged from 10 to 20 cm and its width from 5 to 9 cm. Overall patients’ satisfaction was observed to be 88.5% as either excellent or good and the photographic assessment was 96.2% as either excellent or good. Conclusions Lateral chest wall perforator flaps are reliable and safe option for partial breast reconstruction with an acceptable aesthetic outcome. In the era of oncoplastic breast surgery, they deserve to gain attention especially with the advantages of some modifications added to the classic technique.

Doppler Ultrasound and Computed Tomography Angiography Application in Planning of Lower Extremities Perforator Flaps for the Reconstruction of Acquired Maxillofacial Defects (Case Report)

The study describes a clinical case of preoperative planning of an anterolateral femur perforator flap and a peroneal autograft to eliminate a maxillofacial defect. During preparation for the surgery, an anatomical feature of the structure of both extremities circulatory system was found, which did not allow full use of the donor area tissues for subsequent surgical intervention. This feature was identified by Doppler ultrasound, but the final picture became clear only due to the study by computed tomography angiography.

Designing Anterolateral Thigh Flap Using Ultrasound

Background Preoperative knowledge of themicrovascular anatomy of a patientmay improve safetyand efficacy and reduce morbidity. Today, with the advancement in technology, ultrasound can provide minute details of the structures within the body, which makes this technology very helpful in preoperative evaluation of the traditional perforator flaps as well as thin, superthin, and pure skin perforator flaps. Methods In this article, we will describe the design of one of the most popular perforator flaps, the anterolateral thigh (ALT) flap, using high-frequency and ultrahigh-frequency ultrasound technology. Results Ultrasound technology allows to study preoperatively the ALT donor-site and its microvascular anatomy by using different US modalities in order to provide a virtual surgical plan to the operating surgeon. Conclusion Ultrasound technology allow to expand preoperative knowledge of flap microvascular anatomy and its course within the subcutaneous tissue up to and within the dermis, allowing to select the best perforator for the given reconstruction and the plane of elevation for thin, superthin and pure skin perforator flap.

Designing Lateral Thoracic Wall Perforator Flaps for Breast Reconstruction Using the Ultrasound

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.

The Use of Color Duplex Ultrasound for Local Perforator Flaps in the Extremity

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.
