AbstractThe tissues of the medial arm as a donor site for perforator flap design have several advantages. However, they are relatively underused with limited reports, partly due to unreliable perforator anatomy. Therefore, we aimed to review our preliminary experience using indocyanine green (ICG) angiography to design and elevate preexpanded pedicled brachial artery perforator (BAP) flaps for regional reconstruction. All patients underwent soft tissue reconstructions using a preexpanded BAP flap in two or three stages. ICG angiography was used to localize perforators during both expander insertion and flap elevation. The pedicle was divided at the third stage 3 weeks following flap elevation for head and neck cases. Sixteen patients underwent reconstructions of the head and neck (n = 13) or shoulder/trunk (n = 3) using 14 perforator-plus and 2 propeller BAP flaps. In total, 50 perforators were identified using ICG imaging, all of which were appreciable during both expander placement and flap elevation. Thirty-five perforators were directly visualized during flap elevation, and an additional 15 perforators were not explored but incorporated into the flap. All flaps survived without necrosis, and the donor sites healed uneventfully without complications. The medial arm provides thin and pliable skin for the resurfacing of regional defects with relatively minimal donor-site morbidity. With the assistance of ICG angiography, perforators of the brachial artery can be reliably identified, facilitating the preexpansion and elevation of pedicled BAP flaps for use in head–neck and trunk reconstruction.

The superficial circumflex iliac artery perforator (SCIP) flap is a well-documented, thin, free tissue flap with a minimal donor site morbidity, and has the potential to become the new method for resurfacing moderate-size skin defects. The aim of this study is to describe an easy, reliable, systematic, and standardized approach for preoperative SCIP flap design and perforator characterization, using color-coded duplex sonography (CCDS). A list of customized settings and a straightforward algorithm are presented, which are easily applied by an operator with minimal experience. Specific settings for SCIP flap perforator evaluation were investigated and tested on 12 patients. Deep and superficial superficial circumflex iliac artery (SCIA) branches, along with their corresponding perforators and cutaneous veins, were marked individually with a permanent marker and the anatomy was verified intraoperatively. From this, a simplified procedure for preoperative flap design of the SCIP flap was developed. Branches could be localized and evaluated in all patients. A preoperative structured procedure for ultrasonically guided flap design of the SCIP flap is described. A 100% correlation between the number and emergence points of the branches detected by preoperative CCDS mapping and the intraoperative anatomy was found.

Abstract Introduction While the originally described transverse profunda artery perforator (tPAP) flap is designed to capture the first profunda perforator, our group hypothesized the dominant perforator may not always be captured in this configuration. This study maps the location of dominant profunda perforators using imaging and cadaveric dissections to determine the probability of capturing dominant perforators with the transverse flap design versus the vertical PAP (vPAP) variant. Methods Fifty preoperative magnetic resonance angiogram or computed tomographic angiogram scans (100 total extremities) were examined from autologous breast reconstruction patients between 2015 and 2019. Profunda perforator characteristics that were examined included the distance from the pubic tubercle to the infragluteal fold (IGF), the distance of the perforators from the IGF, distance posterior to the gracilis, the diameter of the perforator at fascial exit, and total number of perforators present. Profunda perforator dissection was performed in 18 cadaveric extremities. Analysis included mean distance from pubic tubercle, distance posterior to the gracilis, diameter at fascial exit, and total number of perforators. Results In imaging analysis, the mean distance from the IGF to the fascial exit of all dominant perforators was 7.04 cm. The mean diameter of the dominant perforator at the fascial exit was 2.61 mm. Twenty-six thighs (26%) demonstrated dominant perforators that exited the fascia greater than 8 cm below the IGF. In cadaver dissections, the mean distance from the pubic tubercle to the fascial exit of all the dominant perforators was 10.17 cm. Nine cadaver specimens (50%) demonstrated perforators that exited the fascia greater than 8 cm below the estimated IGF. Conclusion The dominant perforator can often be missed in the traditional tPAP design. The vPAP incorporates multiple perforators with a long pedicle, excellent vessel diameter, and favorable donor-site.

Background Musculocutaneous perforator flaps offer advantages over musculocutaneous flaps, including reduced donor site morbidity, more predictable reconstruction of soft tissue deformities, and a wider variety of flap options. Perforator flaps are becoming increasingly popular for many applications. In the present study, we set out to examine the various perforators of the thoracoacromial axis through the pectoralis major (PM) muscle with respect to their suitability for transfer to the head and neck region as a pedicled flap. Methods A series of 10 fresh cadavers were injected with lead oxide, gelatin and water (250 mL/kg) through the femoral vessels. The cadavers were cooled and the integument was removed. Perforating vessels from the underlying muscles were marked and the resulting angiograms of the integument and deep tissues were compared with the dissection notes describing the course, size and distribution of the perforating vessels. Results The perforators through the PM muscle to the overlying skin included three regional groups: perforators of the thoracoacromial axis; perforators of the medial intercostal vessels; and perforators of the lateral thoracic artery. The major group of perforators supplying the overlying skin was from the intercostal vessels. However, the thoracoacromial axis did consistently give rise to perforators in the upper portion of the PM muscle. In particular, there were reliable perforators from the clavicular and deltoid branches of the thoracoacromial artery. Discussion The present study illustrates the potential clinical applications of a series of perforator flaps based on the thoracoacromial axis, which may be useful in head and neck reconstructive surgery.

Background Breast reconstruction using deep inferior epigastric artery perforator (DIEP) free flap is widely used because of the advantages of minimizing donor-site morbidity, but it requires technical competency in vascular dissection. This study evaluated the influence of patient factors and vascular status on the time and speed of dissection of the vascular pedicle. Methods DIEP free flap procedures were performed in 49 patients assigned to immediate or delayed reconstruction groups. Factors that significantly influenced the time required and the speed of dissection were evaluated. Results The average total dissection time was 55.9 minutes (34.5 minutes for the intramuscular dissection and 21.4 minutes for the submuscular dissection). The dissection speed for the total vascular pedicle was 2.65 cm/10 minutes (1.71 cm/10 minutes for the intramuscular dissection and 4.30 cm/10 minutes for the submuscular dissection). The presence of a Pfannenstiel scar, length of the vascular pedicle in the intramuscular area, and the number of microclips used significantly correlated with the total dissection time. Conclusion The length of the intramuscular pedicle, number of microclips used, and presence of a Pfannenstiel scar significantly correlated with the total dissection time of the vascular pedicle. An assessment prior to the surgery can reduce the time of operation and make it easier to elevate the flap.

In the current scenario, propeller flaps are an attractive choice for single stage coverage of a large number of defects. They have a more reliable vascular pedicle than traditional flap and allow for greater freedom in design and wide mobilization and minimal donor-site morbidity. Harvesting of a propeller flap requires appropriate patient selection, preoperative planning, and meticulous dissection and these techniques greatly reduce the complication rates. Here, we present a case of a post burn raw area of the right axilla which was debrided and covered with a brachial artery perforator propeller flap.

Background: As the breast cancer diagnosis has increased over recent years, patient have become more informative regarding treatment and reconstructive options, hence the expectation of the results will be very high. Reconstruction of breast with best result and less donor site morbidity is the target.Methods: A total of 20 cases were studied between January 2018 to January 2019 at our hospital to assess the outcome of deep inferior epigastric artery perforator (DIEP) flap for immediate breast reconstruction.Results: A total of twenty DIEP flaps were performed. Mean time required for flap harvest was 125 minutes, and time taken for flap inset was 110 minutes. There was no flap loss in any of the twenty cases. Two patients had fat necrosis. All patients were satisfied with aesthetic outcome.Conclusions: DIEP flap has good aesthetic result with less donor site morbidity.
