Abstract
BACKGROUND Reverse-flow flaps rely on retrograde or reverse flow for drainage and have shown success in reconstructive surgery. However, limited studies have been conducted on the use of reverse-flow recipient veins. Our study proposed bidirectional venous anastomoses within a single recipient vein to optimize venous outflow and evaluated the outcomes of an additional retrograde venous anastomosis group in traumatic extremity reconstruction. METHODS We performed a retrospective analysis of 188 patients with traumatic extremity free flap using two venous anastomoses, which were divided into the antegrade and bidirectional venous anastomosis groups. We analyzed the basic demographic information, flap type, duration between injury and reconstruction, recipient vessels, postoperative flap outcomes, and complications. Propensity score matching was used for the additional analysis. RESULTS Of the 188 patients analyzed, 63 free flaps (126 anastomoses, 33.5%) and 125 free flaps (250 anastomoses, 66.5%) were included in the bidirectional venous anastomosis and antegrade groups, respectively. In the bidirectional vein group, the median time between trauma and reconstruction was 13.0 ± 1.8 days and the mean flap area was 50.29 ± 7.38 cm2 . Radial artery superficial palmar branch perforator flap was most frequently performed (60.3%). In the antegrade vein group, the median time until surgery was 23.0 ± 2.1 days and the mean flap area was 85.0 ± 8.5 cm2 . Thoracodorsal artery perforator flap surgery was the most frequently performed surgery. The two groups were similar in terms of basic characteristics, but the bidirectional group demonstrated significantly higher success rate (98.4% vs. 89.7%, p = .004) and lower complication rate (6.3% vs. 22.4%, p = .007) than the antegrade group. However, these results were not observed after propensity score matching. CONCLUSIONS Our study demonstrated successful results with the recipient vein using reverse flow. Additional retrograde venous anastomosis is a useful option for augmenting venous drainage for reconstruction of distal extremities in cases where dissection of additional antegrade vein is not feasible.

Utilization of the internal mammary perforators as the recipient vessels for microsurgical breast reconstruction: A systematic review and meta-analysis of the literature. Microsurgery 2024; 44:e31105. [PMID: 37675648 DOI: 10.1002/micr.31105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 07/05/2023] [Accepted: 08/17/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND The selection of reliable recipient vessels is essential for successful free tissue transfer. The use of internal mammary intercostal perforators (IMAPs), instead of the internal mammary vessels as the recipient vessels, has been described in breast reconstruction. Debates exist regarding the reliability of these perforators as recipient vessels because of their variability in location and caliber. The aim of this paper was to conduct a systematic literature review and meta-analysis to determine the reliability of the IMAPs as recipient vessels. METHODS A systematic literature review was performed on the "PubMed," "Medline," "Ovid," and "Cochrane library" databases for articles published from January 1990 to March 2021. Exclusion criteria were non-English studies, reports with case number less than 5, cadaveric or animal studies, and studies with incomplete postoperative outcomes. The reliability of using IMAPs for breast reconstruction was determined by assessing the reported rates of partial or complete flap failure and other complications (fat necrosis, skin necrosis, and requirement for revision surgery). RESULTS Three hundred and sixteen cases in 13 studies were included for further analysis with more than 85% of the IMAPs suitable for anastomosis being located in the second and third intercostal spaces. Partial or total flap failure was reported in three of 316 patients (0.95%). The rate of other complications such as fat necrosis, skin necrosis, and requirement for revision surgery were all less than 5%. CONCLUSION With deliberate preoperative planning, delicate perioperative manipulation, and meticulous microvascular anastomosis, the internal mammary perforators can be used as reliable recipient vessels in microvascular breast reconstruction.

Abstract
BACKGROUND The use of internal mammary perforator (IMP) vessels as recipients for free flap breast reconstruction was first described in 1999. Despite numerous advantages over the internal mammary (IM) and thoracodorsal recipient vessels, their widespread use remains mired in concern. This paper describes our method of IMP vessel preparation and outcomes with regard to safety and reliability. METHODS To support the reliability of the IMP vessel preparation, a retrospective study on prospectively collected data of all free flap breast reconstruction patients between 1 July 2016 and 31 July 2019 was performed. Data were collected on patient demographics, type of reconstruction operative details and complications. RESULTS Out of the 450 flaps performed, the IMP vessels were used in 36% of the cases. Of these cases, 18% had received neo-adjuvant chemotherapy and 15% had a history of radiotherapy to the chest wall. In total, 161 flaps were performed to reconstruct 138 breasts (115 single and 23 stacked flaps). Three patients required a return to theatre, with one needing recipient vessel revision from the IMP to the IM vessels due to calibre mismatch. No mastectomy skin flap necrosis, free flap loss or significant fat necrosis were encountered. CONCLUSION This article describes an IM vessel preparation method that results in predictable outcomes in both single and stacked flap reconstructions with a low complication rate. Due to their reliability and versatility, we consider the IMP vessels a valuable attribute to the recipient vessel arsenal of any breast reconstruction microsurgeon.

J Plast Reconstr Aesthet Surg 2023; 84:350-356. [PMID: 37390544 DOI: 10.1016/j.bjps.2023.06.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 06/05/2023] [Accepted: 06/06/2023] [Indexed: 07/02/2023]
Abstract
BACKGROUND The internal mammary artery (IMA) is the preferred recipient vessel for microvascular anastomosis in immediate autologous breast reconstruction following skin-sparing mastectomy (SSM). Although the IMA accounts for approximately 60% of the blood supply to the breast, the exact contribution to the mastectomy skin flap perfusion is unclear. The aim of this observational study was to investigate the impact of using the IMA as a recipient vessel on medial mastectomy skin flap perfusion assessed with indocyanine green angiography (ICGA). METHODS This observational study included ten consecutive women who underwent immediate autologous breast reconstructions following SSM. Two intraoperative indocyanine green (ICG) assessments were performed to assess tissue perfusion of the upper and lower part of the medial mastectomy skin flap: the first following the SSM and the second after clamping the IMA. During a 120-second angiography, three additional images were made after 60, 90, and 120 s. The ICG inflow time and mean, minimum, and maximum fluorescence intensities (FIs) were obtained. RESULTS Four unilateral and six bilateral autologous breast reconstructions were included. There was no difference in tissue perfusion when comparing the inflow time (24.1 s vs. 23.0 s, P = 0.348), the mean FI (131.4 vs. 124.0, P = 0.126), minimum FI (28.6 vs. 33.4, P = 0.086), and maximum FI (253.1 vs. 247.6, P = 0.166) before and after clamping the IMA. CONCLUSION According to this study, the use of the IMA as a recipient vessel does not reduce medial mastectomy skin flap perfusion in patients undergoing immediate autologous breast reconstructions following SSM.

Abstract
BACKGROUND In autologous tissue breast reconstruction, recipient vessels are important for artery perfusion and venous drainage to ensure free flap survival. There are insufficient clinical outcomes to select efficient recipient vessels in bi-pedicled deep inferior epigastric perforator (DIEP) flap reconstruction. METHODS We presented a retrospective observational series of 108 patients regarding the diameter, anastomosis time, and re-anastomosis rate in internal mammary (IM), circumflex scapular (CS), thoracodorsal (TD), thoracoacromial (TA), lateral thoracic (LT), and internal mammary perforator (IMP) vessels of bi-pedicled DIEP flaps for breast reconstruction after mastectomy. The outcomes were the vessel re-anastomosis rate, flap failure rate, vessel anastomosis time, and complications. Data were gleaned from the chi-square test, Fisher's test, and analysis of variance using Scheffe's test as a post hoc analysis. The level of significance was p < 0.05. RESULTS There were no significant differences in the diameters of the artery, first vein, and second vein across the recipient vessels (p > 0.05). However, the anastomosis time was longer in IM and TA than in CS, TD, and LT (p < 0.001). Also, there were no significant differences for re-anastomosis, flap necrosis, and fat necrosis among different recipient vessels (p > 0.05). CONCLUSIONS Because of the altered mastectomy incisions, this study provides complete anatomical vascular properties and suggests that altering recipient vessel selection for bi-pedicled DIEP flaps can shorten anastomosis time and better conceal scars.

A Systematic Review and Meta-analysis of Clinical Outcomes in Autologous Breast Reconstruction Using Internal Mammary Artery Perforators as Recipient Vessels.

Abstract
Recipient vessel selection is vital for successful autologous free-flap breast reconstruction. Internal mammary artery perforators have gained interest as a recipient vessel option. However, previous studies on their microsurgical safety and efficacy are limited and inconsistent. Thus, we conducted a systematic review and meta-analysis to assess the safety and effectiveness of using internal mammary artery perforators as recipient vessels in breast reconstruction. Methods The protocol has been previously published in PROSPERO (CRD42020190020). The PubMed, Scopus, Web of Science, and PROSPERO databases were searched. Two independent reviewers evaluated the articles for inclusion in the study. Study quality was assessed using the Newcastle-Ottawa Scale and the MINORS instrument (Methodological Index for Non-Randomized Studies). Results Of the 361 articles screened, 13 studies were included (313 patients with 318 flaps; 223 unilateral, 31 bilateral, mean average age 51.2 and mean BMI 27.8 ± 1.9). The mean overall success rate was 99.8%, the pooled surgical success rate was 100% [95% confidence interval (CI): 97%-100%], and the overall rate of complications was 11% (95% CI: 7%-18%). The most common complication was vascular-related to microanastomoses, with an incidence of 5% (95% CI: 2%-10%). The fat necrosis rate was 3% (95% CI: 2%-6%). Conclusions This study verified that internal mammary artery perforator vessels are reliable in breast reconstruction, with a high success rate and a relatively low complication rate. Moreover, in selected microsurgical breast reconstruction patients, internal mammary artery perforators may be the primary recipient vessel choice over the internal mammary artery or thoracodorsal vessels.

Abstract
BACKGROUND Microsurgical free tissue transfer (FTT) is a widely employed surgical modality utilized for reconstruction of a broad range of defects, including head and neck, extremity, and breast. Flap survival is reported to be 90%-95%. When FTT fails, salvage procedures aim at establishing reperfusion while limiting ischemia time-with salvage rates between 22% and 67%. There are limited data-driven predictors of successful salvage present in the literature. This systematic review aims to identify predictors of flap salvage. METHODS A systematic literature review was conducted per PRISMA guidelines. Articles included in the final analysis were limited to those investigating FTT salvage procedures and included factors impacting outcomes. Cohort and case series (>5 flaps) studies up until March 2021 were included. Chi-square tests and linear regression modeling was completed for analysis. RESULTS The patient-specific factors significantly associated with salvage included the absence of hypercoagulability (p < .00001) and no previous salvage attempts (p < .00001). Case-specific factors significantly associated with salvage included trunk/breast flaps (p < .00001), fasciocutaneous/osteocutaneous flaps (p = .006), venous compromise (p < .00001), and shorter time from index procedure to salvage attempt (R = .746). Radiation in the head and neck population was significantly associated with flap salvage failure. CONCLUSIONS Given the complexity and challenges surrounding free flap salvage procedures, the goal of this manuscript was to present data helping guide surgical decision-making. Based on our findings, patients without documented hypercoagulability, no previous salvage attempts, fasciocutaneous/osteocutaneous flaps, trunk/breast flaps, and a shorter time interval post-index operation are the best candidates for a salvage attempt.

Abstract
OBJECTIVE To investigate the application of anterior serratus branch of thoracodorsal vessel in repairing chest wall defect. METHODS Between October 2018 and March 2021, bilateral free lower abdominal flaps were used to repair large-area complex defects after chest wall tumor surgery in 23 patients. The patients were all female; the age ranged from 23 to 71 years, with an average age of 48.5 years. There were 11 cases of locally advanced breast cancer, 4 cases of phyllodes cell sarcoma, 3 cases of soft tissue sarcoma, 3 cases of recurrence of breast cancer, and 2 case of osteoradionecrosis. The size of secondary chest wall defect after tumor resection and wound debridement ranged from 20 cm×10 cm to 38 cm×14 cm, the size of flap ranged from 25 cm×12 cm to 38 cm×15 cm, the length of vascular pedicle was 9-12 cm (mean, 11.4 cm). Fourteen cases of simple soft tissue defects were repaired by flap transplantation; 5 cases of rib defects (<3 ribs) and soft tissue defects were repaired by simple mesh combined with flap transplantation; and 4 cases of full-thickness chest wall defect with large-scale rib defect (>3 ribs) were repaired by "mesh plus bone cement" rigid internal fixation combined with flap transplantation. The anterior serratus branch of thoracodorsal vessel was selected as the recipient vessel in all cases, the revascularization methods include 3 types: the proximal end of the anterior serratus branch plus other recipient vessels (13 cases), proximal and distal ends of anterior serratus branch (6 cases), and proximal ends of two anterior serratus branches (4 cases). RESULTS The main trunk of thoracodorsal vessels was preserved completely in 23 patients. All patients were followed up 10-18 months, with an average of 13.9 months. After operation, the flap survived completely, the shape of reconstructed chest wall was good, the texture was satisfactory, and there was no flap contracture deformation. There was only a linear scar left in the flap donor site, and the abdominal wall function was not significantly affected. There was no tumor recurrence during follow-up. CONCLUSION The anterior serratus branch of thoracodorsal vessel has a constant anatomy and causes little damage to the recipient site, so it can provide reliable blood supply for free flap transplantation.

Abstract
The incidence rate of cerebrovascular diseases is increasing year by year, but the accuracy of clinical diagnosis is not high enough to cause disease. Many patients cannot effectively diagnose and treat the disease at the early stage. CT perfusion imaging (CTP) and CT angiography (CTA) were used to diagnose cerebrovascular diseases. In this paper, 26 cases of patients with acute cerebrovascular disease in our hospital from June to August 2020 were selected as the research objects. According to the diagnosis method voluntarily chosen by patients, 6 cases were only detected by CT perfusion imaging, 8 cases were only detected by CT angiography, and the remaining 12 cases were diagnosed by CT perfusion imaging and CT angiography. Then, according to the diagnosis results of the CT image of the patients with cerebrovascular disease, these samples were followed up after 3 months, 6 months, and 9 months, and more accurate diagnosis results were obtained. The study showed that, after 3 months of CT detection, the sensitivity of patients with CTP detection was 67%, that of patients with CTA detection was 72%, and that of patients with combined detection was 83%. After 6 months of CT detection, the sensitivity of patients with CTP detection was 75%, that of patients with CTA detection was 79%, and that of patients with combined detection was 93%. After 9 months of CT detection, the sensitivity of patients with CTP detection was 86%, that of patients with CTA detection was 89%, and that of patients with combined detection was 99%. Therefore, the use of CTA combined with CTP joint detection of acute cerebrovascular disease imaging technology can effectively improve the diagnostic accuracy of patients.

Application of the "Open-Y" technique in recipient perforator vessels: A comparison study between "Open-Y" and conventional end-to-end anastomosis in terms of postoperative complications. Microsurgery 2021; 41:527-532. [PMID: 33566367 DOI: 10.1002/micr.30718] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 12/16/2020] [Accepted: 01/28/2021] [Indexed: 11/06/2022]
Abstract
BACKGROUND Over the last few years, the increasing employment of perforators as both donor and recipient vessels for free flap tissue transfer lead the surgeons to perform increasingly smaller anastomosis. Size discrepancy is a common problem that might affect the patency rate. This has many implications in the outcome of the procedure and the "Open-Y" technique might be useful to perform an easier anastomosis by using a bifurcation area. PATIENTS AND METHODS Between April 2018 and April 2020 a total of 98 patients who received a free tissue transfer reconstruction throughout the body were retrospectively recruited. The "Open-Y" technique of anastomosis was used in the recipient artery of 40 perforator-based flaps, while in 58 cases a conventional anastomosis with nonperforator vessel was performed. The size discrepancy rate and the arterial anastomotic site-related complications were evaluated and compared. RESULTS The flap success rate was 100% (40/40) in the "Open-Y" group, slightly better than the conventional group (96.5%; 56/58) despite a higher size discrepancy rate in the "Open-Y" group (27.5%; 11/40) compared to the conventional one (12%; 7/58) (p value, .053). The rate of complications was different, too. Better results were obtained in the "Open-Y" group with 4/40 (10%) complications compared to the 18/58 (31%) of the conventional group (p value, .013). CONCLUSIONS The "Open-Y" technique is a simple and interesting procedure to increase the vessels' diameter thus reducing size discrepancy and increasing the reliability of the anastomosis. This is extremely valuable in the perforator-to-perforator free tissue transfer setting where surgeons are often forced to work in a supermicrosurgical field. Every time a suitable bifurcation is encountered this might be a useful procedure to increase the end-surface available for the anastomosis or to reduce vessels size discrepancy.

Free tissue transfer with supermicrosurgical perforator-to-perforator (P-to-P) technique for tissue defect reconstruction around the body: Technical pearls and clinical experience. J Plast Reconstr Aesthet Surg 2020; 74:1791-1800.

Abstract
BACKGROUND Resorting to perforators as recipient vessels is a valid alternative that might offer a series of advantages in many situations. They allow the use of a shorter pedicle, reduce the time of dissection, and are a good solution when deep vessels are difficult to reach. The aim of this study is to investigate the efficacy of P-to-P tissue transfer for reconstructing defects in different areas of the body. PATIENTS AND METHODS Between April 2018 and February 2020, 40 patients presenting soft tissue defects were reconstructed by using P-to-P-anastomosed free flap transfer. The cause of the defect was trauma in 16 cases and surgically excised tumor in 24. Five defects were located in the upper extremities, 1 in the neck, 1 in the thorax, and 21 in the lower limb, and 13 cases were breast reconstructions, 2 of which bilateral (43 total flaps). RESULTS Of all 43 flaps, 22 were abdominal flaps, 17 flaps were harvested from the upper thigh, and 4 were harvested from the lower leg. At the 9 month follow-up, 42 flaps were successfully healed, 36 without complications, 3 after wound dehiscence, and 3 after wound infection, and only 1 flap was lost requiring further surgery. Flap failure rate was 2.3%. CONCLUSIONS Free flaps anastomosed in perforator-to-perforator fashion can be safely used in different settings throughout the body. Even if they are technically more demanding, they may allow a quicker operation time and lower morbidity. With the developments in microsurgical instruments, we believe that this technique may become the gold standard for tissue-defect reconstruction.

Microsurgery 2020; 41:355-360. [PMID: 33159486 DOI: 10.1002/micr.30680] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Revised: 05/29/2020] [Accepted: 10/23/2020] [Indexed: 11/12/2022]
Abstract
Head and neck defect reconstruction is a common challenge for plastic surgeons. Microsurgical free tissue transfer is a frequently used solution but its success strictly depends on the quality of recipient vessels. A particularly demanding situation occurs when there are no nearby available vessels because of previous extensive neck dissection and radiotherapy. In similar cases, it is necessary to resort to other and farther vessels. Common alternatives might be the thoraco-acromial vessels, the transverse cervical vessels, and the internal mammary vessel. Recently, the perforator vessels of the internal mammary artery and vein were shown to be safe alternatives as recipient vessels for autologous breast reconstruction, causing less morbidity and allowing adequate perfusion of rather large flaps. Here we present a floor of the mouth reconstruction after cancer relapse resection. In this case, we employed a chimeric anterolateral thigh (ALT) free flap anastomosed to the internal mammary perforator vessels in end-to-end fashion. A 46-years-old male patient presented a defect in the floor of the mouth and base of the tongue after cancer removal. No nearby vessels were available because of extensive fibrosis and damages due to previous surgeries and radiotherapy. Therefore, on the basis of our experience in autologous breast reconstruction, we chose the internal mammary perforator vessels in the recipient side and we harvested a chimeric ALT-based skin island then split into two parts for mouth reconstruction and monitoring. We performed the anastomosis resorting to internal mammary perforator vessels and we obtained a satisfactory result from both the functional and aesthetic point of view. Postoperative course was uneventful and at 6 months follow up the reconstructive result was good with no functional issue. We believe that this might be a valid and modern evolution of the use of internal mammary vessels as recipient vessels and that it is a worthy addition in the field of perforator-anastomosed flaps, extending its application also to head and neck reconstructions. Moreover, a brief literature review about alternative recipient vessels for depleted neck is also provided.

Abstract
Objective To generalize the application and prospect of computed tomographic angiography (CTA) in deep inferior epigastric artery perforator (DIEP) flap transfer for breast reconstruction. Methods The related literature using CTA for DIEP flap reconstruction of breast in recent years was reviewed and analyzed. Results Preoperative CTA can accurately assess the vascular anatomy of the chest and abdomen wall, precisely locating the perforator in the abdominal donor site, and identifying the dominant perforator; guide the selection of intercostal space to explore internal mammary artery and internal mammary artery perforator in the chest recipient vessels. It can also reconstruct the volume of the abdominal flap with reference to the size of the contralateral breast and pre-shape the abdominal flap, which are crucial to formulate the surgical plan and improve the reliability of flap. Conclusion Preoperative CTA has enormous application potential and prospects in locating donor area perforator, in selecting recipient vessels, and in evaluating breast volume for autologous breast reconstruction with DIEP flap.

Internal Mammary Artery and Vein Perforator Vessels as Troubleshooter Recipient Vessels. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2148. [PMID: 31044119 PMCID: PMC6467637 DOI: 10.1097/gox.0000000000002148] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2018] [Accepted: 12/18/2018] [Indexed: 12/03/2022]
Abstract
In autologous breast reconstruction, the internal mammary artery (IMA) and internal mammary vein (IMV) are the standard recipient vessels. Recently, the perforator vessels of the IMA and IMV were found to be a safe alternative as recipient vessels cause less morbidity and allow adequate flap. We describe 2 cases in which the IMA and IMV perforators were used as additional recipient vessels to overcome intraoperatively occurred complications. The IMA and IMV perforators have some advantages over the IMA/IMV: (1) the dissection is done superficially and directly from the mastectomy site. Flap positioning is facilitated. (2) There is no need to remove a rib, which reduces postoperative pain and possible contour deformities. (3) Possible injuries to the pleura are avoided. (4) The IMA is spared for possible cardiac revascularization. Disadvantages can be that (1) the IMA perforators are not always present with the required caliber, (2) the position of the perforators is not suitable to adequately position the flap, and (3) dissection of the IMA perforators and their anastomoses has a learning curve. In the presented cases, the IMA and IMV perforators have proven to offer a simple solution to avoid complications. The additional dissection is done from the same recipient site, and there is no further dissection or incision necessary at the axilla or to explore the cephalic vein. This keeps morbidity and operation time low. Therefore, we suggest keeping the IMA and IMV perforators in mind not only as primary recipient vessels but also as a possible solution for intraoperatively occurred complications.

Expanding the use of internal mammary artery perforators as a recipient vessel in free tissue transfer: An anatomical analysis by computed tomography angiography in breast cancer patients.

[PMID: 30830973 DOI: 10.1002/micr.30446] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2018] [Revised: 01/25/2019] [Accepted: 02/22/2019] [Indexed: 11/11/2022]
Abstract
BACKGROUND The internal mammary artery (IMA) perforator has assumed recent prominence as recipient vessels in free autologous breast reconstruction. However, anatomical understanding is unclear, due to limited cadaver and clinical studies. We evaluated the usability of these vessels by evaluating perforator size, dominance, laterality, interspace location, and relationship with breast volume. METHODS A retrospective review assessed 197 female patients with breast cancer who had undergone computed tomography angiography (CTA) of the chest wall. The average age and body mass index (BMI) of patients was 49.0 ± 6.5 years and 24.2 ± 5 .8 kg/m2 , respectively. The average volume of breasts was 437 ± 190 mL. Our analysis focused on the anatomy of IMA perforator and its relationship to volume and BMI. RESULTS A total of 377 hemi-chest evaluations were performed. Most patients (95.5%) had sizeable perforating artery identified on CTA. Among all sizeable perforators identified, the mean diameter of the most dominant arterial perforator was 1.8 ± 0 .8 mm. The right hemi-chest had significantly larger perforators than the left (1.9 ± 0 .9 mm vs. 1.7 ± 0 .7 mm, p = 0.002). The first intercostal space (ICS) had a slightly greater of perforators than second ICS (34.6% vs. 29.8%, p = 0.172). However, second ICS had a greater number of most dominant perforators compared to first ICS (38.9% vs. 34.7%, p = 0.357). Perforators from first ICS emerge medial to the sternal edge and breast footprint. When dividing groups with 0-1 versus 2-3 reliable perforators, breast volume was significantly higher in the later (422.0 mL vs. 461.2 mL, p = 0.019). CONCLUSION These results are expected to encourage microsurgeons to use the IMA perforator by providing a clear anatomical roadmap.

Abstract
BACKGROUND Nipple-sparing mastectomy poses challenges in providing esthetically-pleasing immediate autologous breast reconstruction. This study was to investigate the outcomes of nipple-sparing mastectomy with breast reconstruction using free abdominal flaps between two different recipient sites. METHODS Between 2010 and 2016, 79 patients who underwent nipple-sparing mastectomy with autologous breast reconstruction using thoracodorsal (TD) vessels in 30 cases or internal mammary (IM) vessels in 49 cases were investigated. Demographics, intraoperative findings, complications, and quality of life using Breast-Q questionnaire were compared between two groups. RESULTS All flap survived. There was no statistical difference in age, BMI, ischemia time, and flap-used percentage. The TD artery had a statistically smaller diameter 1.8 ± 0.4 mm than the IM artery 2.7 ± 0.43 mm (p = 0.02). At a mean follow-up of 44.4 ± 35.2 months, there was no statistical difference in total complication rates between TD and IM groups (23.3% and 36.7%, respectively, p > 0.05). The "psychosocial well-being" of Breast-Q in TD group 83.9 ± 14.6 was statistically greater than IM group 72.8 ± 17.6 (p = 0.04). CONCLUSIONS Nipple-sparing mastectomy with immediate breast reconstruction using TD vessels with a low lateral scar is a safe procedure that provides an inconspicuous scar with better cosmesis and minimal complication rate.

Abstract
Background Keloid therapy remains a great challenge for plastic surgeons, especially when the defect cannot be closed primarily, necessitating tissue transplantation. Here, we introduce a new treatment modality, called the sandwich therapy, for presternal keloids; the sandwich therapy incorporates preradiotherapy, superficial circumflex iliac artery perforator (SCIP) flap transplantation, and postradiotherapy. Methods From December 2012 to October 2013, 12 patients received the “sandwich therapy.” For the protocol, all patients went through 5 days of specific events: the precut procedure, preradiotherapy, resection and SCIP flap transplantation, donor site radiotherapy, and final presternal radiotherapy. Results All the flaps survived completely. No complication was observed during the perioperative period. With a mean follow-up of 12 months, only 1 case was reported with an incisional hypertrophic scar. In all patients, the main discomfort complaints were resolved postoperatively. Conclusions A low-tension or without-tension closure could be achieved with SCIP flap transplantation. The perioperative radiotherapy could further lower the risk of keloid recurrence. The sandwich therapy provides a new surgical approach to presternal keloid treatment.

Unilateral Internal Mammary Recipient Vessels for Bilateral DIEP Flap Breast Reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2017; 5:e1359.

Abstract
The deep inferior epigastric perforator flap has become increasingly popular for breast reconstruction with the most common recipient vessels being the internal mammary artery and vein. In certain cases, however, these recipient vessels are inadequate due to an absent or diminutive vein. Moreover, patients at high risk for future coronary artery disease may sacrifice the best conduit for coronary revascularization if the internal mammary recipients are used. Alternative recipient vessels, including the thoracodorsal, thoracoacromial, external jugular, and cephalic vessels have significant limitations. In this report, we describe a novel technique using unilateral internal mammary recipient vessels for bilateral free flap breast reconstruction. Two cases are presented that represent distinct indications for this technique: (1) absence or inadequacy of unilateral recipient vessels and (2) preservation of the left internal mammary system for future bypass in patients at high risk for coronary artery disease.

Abstract
CONTEXT The internal mammary artery perforator vessels (IMPV) as a recipient in free flap breast reconstruction offer advantages over the more commonly used thoracodorsal vessels and the internal mammary vessels (IMV). AIMS This study was designed to assess the anatomical consistency of the IMPV and the suitability of these vessels for use as recipients in free flap breast reconstruction. PATIENTS AND METHODS Data from ten randomly selected female patients who did not have any chest wall or breast pathology but had undergone a computed tomography angiography (CTA) for unrelated diagnostic reasons from April 2013 to October 2013 were analysed. Retrospective data of seven patients who had undergone mastectomy for breast cancer and had been primarily reconstructed with a deep inferior epigastric artery perforator free flap transfer using the IMPV as recipient vessels were studied. RESULTS The CTA findings showed that the internal mammary perforator was consistently present in all cases bilaterally. In all cases, the dominant perforator arose from the upper four intercostal spaces (ICS) with the majority (55%) arising from the 2nd ICS. The mean distance of the perforators from the sternal border at the level of pectoralis muscle surface on the right side was 1.86 cm (range: 0.9-2.5 cm) with a mode value of 1.9 cm. On the left side, a mean of 1.77 cm (range: 1.5-2.1 cm) and a mode value of 1.7 cm were observed. Mean perforator artery diameters on the right and left sides were 2.2 mm and 2.4 mm, respectively. CONCLUSIONS Though the internal mammary perforators are anatomically consistent, their use as recipients in free tissue transfer for breast reconstruction eventually rests on multiple variables.

Abstract
Use of the retrograde limb of the internal mammary vein has been described previously as a lifeboat for venous congestion but not prophylactically. Maximizing the length of the deep inferior artery perforator (DIEP) flap pedicle, identifying and dissecting the superficial inferior epigastric vein proximally in every patient, and taking advantage of the retrograde internal mammary vein are all technical details that facilitate the additional venous anastomosis and flap inset. Performing a second venous anastomosis routinely using the superficial inferior epigastric vein to the retrograde internal mammary vein helps with flap inset.

An Appraisal of Internal Mammary Artery Perforators as Recipient Vessels in Microvascular Breast Reconstruction-An Analysis of 515 Consecutive Cases. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2016; 4:e1144.

Abstract
Background: The usage of internal mammary artery perforators (IMAPs) has been described in autologous breast reconstruction although IMAPS are not yet considered standard recipient vessels. It remains unclear if these vessels can be safely used in large flaps after radiation therapy or in delayed breast reconstruction. Methods: Over a 2-year period, 515 free flaps for autologous breast reconstruction were performed on 419 patients by 2 surgeons (S1 and S2). In a retrospective analysis, time of reconstruction, ischemia time, flap weight, diameter of couplers, and complications were analyzed. All 515 flaps were compared in a subset with regard to the 2 surgeons: S1 who always used the IMA as a recipient vessel and S2 who attempted IMAP use if possible. Results: Of all 515 flaps, 424 were abdominal flaps and 91 flaps were from the upper thigh. Three hundred six cases were immediate reconstructions, and 112 were delayed reconstructions. In 97 cases, implants were converted to autologous tissue. In 112 cases, the IMAPs were used; of these, 82 were immediate and 17 were delayed reconstructions, and in 13 cases, implants were removed. Thirty-five percent of all anastomoses to IMAPs had previous radiation therapy. The flap failure rate was 1.9%. In none of these cases, the IMAPs were used. S1 never used the IMAP, and S2 used the IMAP in 37% of all of his flaps. Conclusions: IMAPs were safely used in all kinds of reconstructions and after radiation therapy, with no flap failure or negative effects on mastectomy skin flap perfusion. Using the IMAPs as recipient vessels is a further step toward simplifying microsurgical breast reconstruction.

Abstract
Background: The deep inferior epigastric perforator (DIEP) procedure is regarded a safe option for autologous breast reconstruction. Reoperations, however, may occur, and there is no consensus in the literature regarding the risk factors. The aim of this study was to identify factors associated with reoperations in DIEP procedure. Patients and Methods: A retrospective study of consecutive patients undergoing DIEP breast reconstruction 2007 to 2014 was performed and included a review of 433 medical charts. Surgical outcome was defined as any unanticipated reoperation requiring return to the operating room. Multivariate regression analysis was utilized to identify predictors of reoperation. The following factors were considered: age, body mass index, comorbidity, childbearing history, previous abdominal surgery, adjuvant therapy, reconstruction laterality and timing, flap and perforator characteristics, and number and size of veins. Results: In total, 503 free flaps were performed in 433 patients, 363 (83.8%) unilateral and 70 (16.2%) bilateral procedures. Mean age was 51 years; 15.0% were obese; 13.4% had hypertension; 2.3% had diabetes; 42.6% received tamoxifen; 58.8% had preoperative radiotherapy; 45.6% had abdominal scars. Reoperation rate was 15.9% (80/503) and included flap failure, 2.0%; partial flap loss, 1.2%; arterial thrombosis, 2.0%; venous thrombosis, 0.8%; venous congestion, 1.2%; vein kinking, 0.6%. Other complications included bleeding, 2.2%; hematoma, 3.0%; fat necrosis, 2.8%, and infection, 0.2%. Factors negatively associated with reoperation were childbearing history (odds ratio [OR]: 3.18, P = 0.001) and dual venous drainage (OR: 1.91, P = 0.016); however, only childbearing remained significant in the multivariate analyses (OR: 4.56, P = 0.023). Conclusions: The history of childbearing was found to be protective against reoperation. Number of venous anastomoses may also affect reoperation incidence, and dual venous drainage could be beneficial in nulliparous patients.

Abstract
The introduction of the transverse rectus abdominis myocutaneous flap in the 1970s marks the beginning of modern breast reconstruction although implants were available even earlier mainly for breast augmentation. Mastectomy techniques have evolved from the early Halsted radical mastectomy to the modern skin sparing mastectomy. The latter made possible using implants for breast reconstruction. Although prosthetic reconstruction provides a simpler procedure with quick recovery, autologous reconstruction offers more natural and long-lasting results especially in the setting of radiotherapy. Both forms have been extensively used at the MD Anderson Cancer Center (MDACC) while microsurgical breast reconstruction has been the hallmark of the MDACC experience. One of the most challenging areas of breast reconstruction is how to achieve good results without compromising adjuvant therapy when post-mastectomy radiotherapy is required. Managing upper extremity lymphedema following breast cancer treatment is another difficult issue which has gained great attention in recent years. This article highlights the important work in various aspects of breast reconstruction that has been done at the MDACC.

Abstract
Selecting potential recipient vessel options for free flap anastomosis is an important consideration in microsurgical breast and chest wall reconstruction. In these settings, the most common comprise the internal mammary and thoracodorsal vessels, although alternative anastomotic sites have also been described. On occasion, consideration of these alternatives becomes a necessity. The use of five separate recipient vessels is highlighted in a unique case of recurrent locally advanced breast cancer requiring multiple complex reconstructions using free tissue transfer. A 56-year-old lady presented for delayed breast reconstruction one year after radical mastectomy for locally advanced lobular breast cancer. Despite wide resections, local chest-wall recurrence five times necessitated five microsurgical reconstructions, using separate recipient pedicles: internal mammary vessels, thoracodorsal vessels, serratus branch of thoracodorsal vessels, intercostal vessels and thoracoacromial vessels. All flaps survived completely, without donor or recipient complications. There has not been a subsequent recurrence at 6 months since last reconstruction. The purpose of this report is to present the first reported case of microsurgical chest wall reconstruction using five separate free flaps requiring anastomosis to multiple recipient vessels for anterior chest wall coverage, to present a literature-based and clinical review of the regional vascular anatomy of the anterior chest wall, and to present an operative approach algorithm. In such complex cases, this understanding can facilitate a streamlined approach to management. © 2014 Wiley Periodicals, Inc. Microsurgery 37:66-70, 2017.

Cephalic Vein Transposition versus Vein Grafts for Venous Outflow in Free-flap Breast Reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2014; 2:e141.

Abstract
Introduction: When recipient veins for free-flap breast reconstruction are unavailable or inadequate, vein grafts or cephalic vein transposition (CVT) an option to provide alternate venous outflow. There are no comparative data to elucidate the indications and outcomes for each. We hypothesize that the CVT is as reliable as vein grafts when indicated. Methods: All consecutive cases where a CVT or venous vein grafts were used for free-flap breast reconstruction between 2000 and 2012 were reviewed. Patient demographics, operative notes, indications, and flap survival were compared between the 2 groups. Results: Ten patients underwent a CVT and 38 patients received a vein graft for insufficient venous outflow. There were no differences in average age, body mass index, or comorbid conditions between the groups. Similarly, there was no difference in previous radiotherapy, timing of reconstruction, or side of reconstruction. A CVT was used for salvage following venous thrombosis in 7 patients (70.0%) and for primary venous outflow in the remaining patients due to inability to use the internal mammary vein. Vein grafts were performed primarily in 31 patients, 22 for augmenting venous drainage (supercharge), 9 for the dominant venous outflow, and 7 for salvage of a thrombosis. One patient in each group suffered a complete loss of the free flap (cephalic: 10.0% vs vein graft: 14.3%, P = 0.36). Conclusions: The CVT is a reliable alternate venous outflow that can be used as a primary recipient vein or as a salvage option following venous thrombosis. Surgeons should consider a CVT when primary recipient veins are compromised or unavailable.

Abstract
BACKGROUND In microsurgical breast reconstruction, an adequate selection of recipient vessels is crucial for a successful outcome. Although the internal mammary (IM) vessels offer an attractive option, the internal mammary perforator (IMP) vessels are becoming a reliable alternative. The purpose of this study is to investigate the external diameters, lumen area, and atherosclerotic lesions changes of the IMP, IM, and deep inferior epigastric (DIE) vessels through quantitative and qualitative histomorphometric analysis. METHODS Ninety-six vessels of bilateral IM, IMP, and DIE vessels from 16 fresh female cadavers were evaluated. Mean age was 54.06 ± 5.7 years. External diameters, lumen area, and degenerative changes of the tunica intimae and media were analyzed by qualitative histomorphometric analysis. RESULTS Seventy-one vessels (20 IM, 31 IMP, and 20 DIE vessels) were included in the final histological analysis. A statistically lower external diameters and lumen area were presented by the IMP. The DIE vessels showed a lower incidence (10%) of moderate and severe intimal layer degenerative changes (P = 0.0589). The IMP and DIE vessels showed a lower incidence (9.4 and 25%, respectively) of major media layer degenerative changes (P = 0.0001). No major arterial degenerative lesions were observed in the IMP arteries. CONCLUSION Although the IMP external diameters and lumen area were lower than the IM, the results of this study indicated that the tunica media layer in the IMP is less damaged than the other recipient vessels. The results of the comparative histological study permitted to describe additional advantages and disadvantages of using IMP as a recipient vessel for free flap breast reconstruction.

Abstract
Background Partially resecting ribs of the recipient site to facilitate easy anastomosis of the internal mammary vessels to free flaps during breast reconstruction can cause chest wall pain or deformities. To avoid this, the intercostal perforating branches of the internal mammary vessels can be used for anastomosis. The purpose of this study was to investigate the location and size of the internal mammary perforator vessels based on clinical intraoperative findings and to determine their reliability as recipient vessels for breast reconstruction with microsurgical free tissue transfer. Methods Twelve patients were preoperatively screened for the presence of internal mammary perforators using Doppler tracing. After modified radical mastectomy was performed by a general surgeon, the location and size of the internal mammary perforator vessels were microscopically investigated. The external diameter was examined using a vessel-measuring gauge from a mechanical coupling device, and the distance from the mid-sternal line to the perforator was also measured. Results The largest arterial perforator averaged 1.5 mm, and the largest venous perforator averaged 2.2 mm. Perforators emerging from the second intercostal space had the largest average external diameter; the second intercostal space also had the largest number of perforators arising from it. The average distance from the mid-sternal line to the perforator was 20.2 mm. Conclusions Internal mammary perforators presented consistent and reliable anatomy in this study. Based on these results, the internal mammary perforators appear to have a suitable diameter for microvascular anastomosis and should be considered as an alternative recipient vessel to the internal mammary vessel.

Abstract
BACKGROUND AND AIM Preoperative assessment of the internal mammary artery perforating (IMAP) branches enhances IMAP-based reconstructive procedures. Conventionally, color-flow Doppler, selective catheter arteriography, or CT angiography is used for such assessment. We studied how often these examinations may be rendered superfluous by assessment of previously performed diagnostic examinations. METHODS A radiologist and a plastic surgeon jointly assessed whether information on the dominant IMAP could sufficiently be obtained from the thoracic CT scans of 12 head and neck cancer patients and 12 breast cancer patients, and from the mammary MRI of 12 breast cancer patients. Secondly, we retrospectively assessed in how many of the 10 patients who underwent an IMAP-flap head and neck reconstruction, and in how many of the 10 women who consecutively underwent a deep inferior epigastric perforator (DIEP) flap mammary reconstruction such previous diagnostic examinations were available and informative regarding the level of the dominant perforator. RESULTS All 24 CT scans and 11 of the 12 MRI scans sufficiently allowed assessment of the level of the dominant IMAP. Previous information had already been available in all 10 DIEP flap patients and 6 of the 10 IMAP-flap patients. The distribution of IMAP dominance over the intercostal levels on the scans differed from that found by cadaveric or intraoperative assessment. CONCLUSIONS Previously performed diagnostic CT scans and MRI scans that included the parasternal region usually allow sufficient preoperative assessment of the internal mammary perforators for reconstructive procedures. We advocate re-assessment of such previous examinations before ordering additional angiography. Additionally, we suggest to include the parasternal region in diagnostic scans.

Abstract
Background The radioguided localization of occult breast lesions (ROLL) technique often utilizes iodinated radiographic contrast to assure that the local injection of 99mTc-MAA corresponds to the location of the lesion under investigation. However, for this application, this contrast has several shortcomings. The objective of this study was to evaluate the safety, effectiveness and technical feasibility of the use of polydimethylsiloxane (PDMS) as radiological contrast and tissue marker in ROLL. Materials and methods. The safety assessment was performed by the acute toxicity study in Wistar rats (n = 50). The radiological analysis of breast tissue (n = 32) from patients undergoing reductive mammoplasty was used to verify the effectiveness of PDMS as contrast media. The technical feasibility was evaluated through the scintigraphic and histologic analysis. Results We found no toxic effects of PDMS for this use during the observational period. It has been demonstrated in human breast tissue that the average diameter of the tissue marked by PDMS was lower than when marked by the contrast medium (p <0.001). PDMS did not interfere with the scintigraphic uptake (p = 0.528) and there was no injury in histological processing of samples. Conclusions This study demonstrated not only the superiority of PDMS as radiological contrast in relation to the iodinated contrast, but also the technical feasibility for the same applicability in the ROLL.

Abstract
OBJECTIVE To identify possible avenues of sparing the internal mammary artery (IMA) for coronary artery bypass grafting (CABG) in women undergoing autologous breast reconstruction with deep inferior epigastric artery perforator (DIEP) flaps. BACKGROUND Optimal autologous reconstruction of the breast and coronary artery bypass grafting (CABG) are often mutually exclusive as they both require utilisation of the IMA as the preferred arterial conduit. Given the prevalence of both breast cancer and coronary artery disease, this is an important issue for women's health as women with DIEP flap reconstructions and women at increased risk of developing coronary artery disease are potentially restricted from receiving this reconstructive option should the other condition arise. METHODS The largest clinical and cadaveric anatomical study (n=315) to date was performed, investigating four solutions to this predicament by correlating the precise requirements of breast reconstruction and CABG against the anatomical features of the in situ IMAs. This information was supplemented by a thorough literature review. RESULTS Minimum lengths of the left and right IMA needed for grafting to the left-anterior descending artery are 160.08 and 177.80 mm, respectively. Based on anatomical findings, the suitable options for anastomosis to each intercostals space are offered. In addition, 87-91% of patients have IMA perforator vessels to which DIEP flaps can be anastomosed in the first- and second-intercostal spaces. CONCLUSION We outline five methods of preserving the IMA for future CABG: (1) lowering the level of DIEP flaps to the fourth- and fifth-intercostals spaces, (2) using the DIEP pedicle as an intermediary for CABG, (3) using IMA perforators to spare the IMA proper, (4) using and end-to-side anastomosis between the DIEP pedicle and IMA and (5) anastomosis of DIEP flaps using retrograde flow from the distal IMA. With careful patient selection, we hypothesize using the IMA for autologous breast reconstruction need not be an absolute contraindication for future CABG.

Abstract
The free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) and deep inferior epigastric perforator (DIEP) flaps involve transferring skin and subcutaneous tissue from the lower abdominal area and have many features that make them well suited for breast reconstruction. The robust blood supply of the free flap reduces the risk of fat necrosis and also enables aggressive shaping of the flap for breast reconstruction to optimize the aesthetic outcome. In addition, the free MS-TRAM flap and DIEP flap require minimal donor-site sacrifice in most cases. With proper patient selection and safe surgical technique, the free MS-TRAM flap and DIEP flap can transfer the lower abdominal skin and subcutaneous tissue to provide an aesthetically pleasing breast reconstruction with minimal donor-site morbidity.

Abstract
INTRODUCTION A limiting factor in the use of perforators as recipient vessels is the small-to-large diameter mismatch often encountered. Mismatches less than 1:1.5 may be managed by dilatation of the smaller vessel and by differentially-spaced suture bites. Beyond this ratio, little evidence exists to direct the choice of end-to-end anastomotic technique. Following in silico work and the characterisation of a rodent superficial caudal epigastric/femoral artery model, we conducted an experimental series examining two techniques - an oblique section of the smaller vessel and invaginating the smaller vessel inside the larger. MATERIALS AND METHODS A paired design was used. To test for a difference in patency of >5% required a total of 156 animals (312 anastomoses). Side and technique were randomised. Two investigators performed the anastomoses. A single revision was permitted. Anastomoses were timed and patency was tested at one hour, one week and at six weeks. RESULTS There was no significant difference in patency at each of the three time points (p = 0.8026, 0.2963 and 0.8137). The invagination technique was significantly faster to perform (p < 0.0001). There was a significant association between the investigator and both patency and the time taken to complete an anastomosis. Independent of the investigator, a revision was more likely to be necessary with the oblique end-to-end technique, and a revision having been performed showed a highly significant association with an anastomosis having failed at 1 h (p < 0.0001, OR 33.333). CONCLUSIONS In the management of microarterial size discrepancy between 1:1.5 and 1:2.5, an invaginating anastomosis is faster to perform and produces comparable patency in a rat model.
