Purpose: The high success rate of free flap transfers is well documented in previous literature, and is possible due to the early detection of vascular compromise and timely reoperation. We specifically analyzed the operative results of immediate and delayed reconstruction with free transverse rectus abdominis musculocutaneous(TRAM) flap respectively in order to reveal its distinctive features on timing and causes of vascular compromise. Methods: The senior author operated on 158 patients, 161 cases of free TRAM flap for breast reconstruction. 51 patients underwent delayed reconstruction, whilst immediate reconstruction was performed in the other 107 patients. All patients were monitored every 3 hours for the first 3 days. We reviewed medical records of all patients, and tested statistical significance with the Fisher's test. Results: Reoperation was performed in 20 cases, but the cases include hematoma with bleeding focus and arterial anastomosis site rupture due to abrupt arm abduction. We performed reoperation in 15 cases of suspicious vascular compromise. Flap compromise was noticed mostly within 24 hours, but not longer than 72 hours. Venous compromise was dominant by 11 cases (73.3%). There was difference in the timing of flap compromise between immediate and delayed reconstruction. All the cases of delayed reconstruction did not show signs of vascular compromise after 12 hours postoperatively. On the other hand, cases of vascular compromise were observed until 72 hours postoperatively in cases of immediate reconstruction. Conclusion: Delayed reconstruction showed vascular compromise within 12 hours postoperatively, while immediate reconstruction showed compromised until the 3rd postoperative day. If more aggressive monitoring is maintained during this period, we believe salvage of flaps may be increased with more efficiency.

Background The objective of this paper was to describe a novel technique for improving the maintenance of nipple projection in primary nipple reconstruction by using acellular dermal matrix as a strut in one of three different configurations, according to the method of prior breast reconstruction. The struts were designed to best fill the different types of dead spaces in nipple reconstruction depending on the breast reconstruction method. Methods A total of 50 primary nipple reconstructions were performed between May 2012 and May 2015. The prior breast reconstruction methods were latissimus dorsi (LD) flap (28 cases), transverse rectus abdominis myocutaneous (TRAM) flap (10 cases), or tissue expander/implant (12 cases). The nipple reconstruction technique involved the use of local flaps, including the C-V flap or star flap. A $1{\times}2-cm$ acellular dermal matrix was placed into the core with O-, I-, and L-shaped struts for prior LD, TRAM, and expander/implant methods, respectively. The projection of the reconstructed nipple was measured at the time of surgery and at 3, 6, and 9 months postoperatively. Results The nine-month average maintenance of nipple projection was $73.0%{\pm}9.67%$ for the LD flap group using an O-strut, $72.0%{\pm}11.53%$ for the TRAM flap group using an I-strut, and $69.0%{\pm}10.82%$ for the tissue expander/implant group using an L-strut. There were no cases of infection, wound dehiscence, or flap necrosis. Conclusions The application of an acellular dermal matrix with a different kind of strut for each of 3 breast reconstruction methods is an effective addition to current techniques for improving the maintenance of long-term projection in primary nipple reconstruction.

Prior abdominal liposuction can be viewed as a relative or absolute contraindication to abdominally based autologous breast reconstruction given concerns for damaged perforators and scarring complicating intraoperative dissection. This systematic review aims to explore the outcomes of abdominally based breast reconstruction in patients with a history of abdominal liposuction. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-guided literature search was conducted using PubMed, Scopus, and Web of Science from the earliest available date through June 2020. Deep inferior epigastric perforator, muscle-sparing transverse rectus abdominis musculocutaneous (TRAM), superficial inferior epigastric artery, and pedicled TRAM flaps were included for evaluation. Complications included total or partial flap loss, fat necrosis, seroma, delayed wound healing, and donor site complications. After inclusion criteria were applied, 336 non-duplicate articles were screened, yielding 11 for final review, representing 55 flaps in 43 patients. There was no instance of total flap loss, eight (14.5%) flaps developed partial loss or fat necrosis, three (5.4%) flaps had delayed wound healing, and two (4.6%) patients had donor site complications. Most authors (8/11) utilized some type of preoperative imaging. Doppler ultrasonography was the most used modality, and these patients had the lowest rate of partial flap loss or flap fat necrosis (8%), followed by those without any preoperative imaging (10%). In conclusion, this review supports that patients undergoing abdominally based autologous breast reconstruction with a history of abdominal liposuction are not at an increased risk of flap or donor site complications. Although preoperative imaging was common, it did not reliably decrease complications. Further prospective studies are needed to address the role of imaging in improving outcomes.
Background The Island transverse rectus abdominis musculocutaneous (TRAM) flap is well vascularized with very reliable blood flow, because all perforators of the zone I are included when it is harvested. The number of perforators, topographic mapping, and their relationship with reconstructed outcomes were investigated. Methods Fifty patients with Island TRAM breast reconstruction from September 2021 to August 2022 were investigated. The zone I was divided into a total of eight sections. Under the loupe magnification, all perforators larger than 0.5 mm in zone I were counted with fine dissection, and photographs were taken in background of vessel loops. Complications like flap necrosis, seroma, and hematoma were also investigated. Result There are 12 ideal perforators on average in zone I such as one perforator in section I, II, IV, V, VI, VIII, and three perforators in section III and VII. However, two perforators (M6 and L6) below arcuate line were sacrificed in the time of flap harvest to prevent hernia. Island TRAM included 10 perforators on average (5 perforators in each side) above arcuate line to be transferred to the recipient site. Only minor complications were identified. Conclusion The Island TRAM flap includes 10 perforators to get the vigorous blood flow. The periumbilical to upper medial perforators become more dominant in the perfusion of the flap after deep inferior epigastric artery division. Well preserved perforators will guarantee the satisfactory breast reconstruction with the least complication.

Background Previously, surveys have been used to investigate breast reconstruction statistics. Since 2015, breast reconstruction surgery after mastectomy has been covered by the National Health Insurance Service in Korea, and data from breast reconstruction patients are now available from the Health Insurance Review and Assessment Service (HIRA). We investigated statistics in breast reconstruction in Korea through statistics provided by the HIRA Big Data Hub. Methods We investigated the number of cases in mastectomy and breast reconstruction methods from April 1, 2015 to December 31, 2016. Data were furnished by the HIRA Big Data Hub and accessed remotely online. Results were tabulated using SAS Enterprise version 6.1. Results The 31,155 mastectomy cases included 7,088 breast reconstruction cases. Implant-based methods were used in 4,702 cases, and autologous methods in 2,386. The implant-based reconstructions included 1,896 direct-to-implant and 2,806 tissue-expander (2-stage) breast reconstructions. The 2-stage tissue-expander reconstructions included 1,624 expander insertions (first stage) and 1,182 expander-to-permanent-implant exchanges (second stage). Of the autologous breast reconstructions, 705 involved latissimus dorsi muscle flaps, 498 involved pedicled transverse rectus abdominis myocutaneous (TRAM) flaps, and 1,183 involved free-tissue transfer TRAM flaps, including deep inferior epigastric perforator free-tissue transfer flaps. There were 1,707 nipple-areolar complex reconstructions, including 1,565 nipple reconstructions and 142 areola reconstructions. The 1-year mean number of breast reconstructions was 4,050. Conclusions This was the first attempt to evaluate the total number of breast reconstruction procedures using accurate, comprehensive data, and our findings may prove valuable as a foundation for future statistical studies of breast reconstruction procedures in Korea.
Purpose: The selection of the recipient vessels in breast reconstruction has a great influence on the surgical result and the shape of the reconstructed breast. We would like to introduce the criteria for the selection of recipient vessels in delayed reconstruction of the breast. Methods: We studied 56 patients with delayed breast reconstruction using free TRAM flaps from April 1994 to December 2006. The thoracodorsal and the ipsilateral internal mammary vessels were used as recipients in 25 patients each, the opposite internal mammary vessels in 3 patients, the thoracoacromial vessels in 2 patients, and the transverse cervical artery with the cephalic vein in 1 patient. The survival rate of the flaps, the vessel diameter, the length of the pedicles, and the convenience of vessel dissection were studied. Results: The diameter of the recipient vessel did not influence the anastomosis. The operation time, the survival rate of flap, the postoperative complications showed no significant difference according to the recipient vessel. Dissection of the thoracodorsal vessels was tedious due to scar formation from the prior operation. Dissection of the internal mammary vessels proved to be relatively easy, and the required length of the pedicle was shorter than any other site, but the need for removal of rib cartilage makes this procedure inconvenient. Conclusion: The first choice of the recipient vessel in immediate breast reconstruction is the thoracodorsal vessels, but in cases of delayed reconstruction the internal mammary vessels are favored as the first choice, because the thoracodorsal vessels have a high unusability rate. If the ipsilateral internal mammary vessels prove to be useless, the contralateral vessels can be used. The thoracoacromial vessels are useful, when the mastectomy scar is located in the upper portion. The transverse cervical artery and the cephalic vein can serve as the last resort, if all other vessels are unreliable.
Purpose: In cases of breast reconstruction with a free transverse rectus abdominis musculocutaneous (TRAM) flap after skin-sparing mastectomy with nipple-areolar complex (NAC) removal, the flat contour of the flap's skin paddle can easily look unnatural and dissatisfying. Reconstructed NAC on the flap surface lacks the elevated contour that the normal areola possesses, resulting in an unnatural final result. Therefore, we would like to introduce a novel method to improve this problem and report the satisfactory results we obtained. Methods: Operations were conducted on 19 patients who underwent immediate breast reconstruction with a free TRAM flap and skin-sparing mastectomy from January 2009 to January 2010, with a mean follow-up of nine months. While the TRAM free flap was being inset, a purse-string suture was carried out on the dermal layer of skin flap to create a slight protrusion with Gore-$Tex^{(R)}$ sutures. Results: The elevated mound surrounding the NAC was well maintained for an average follow-up period of nine months. Nipple projection was also well maintained. There was no complaint about breast contour or nipple height reduction. In addition, there was no reported incidence of other complications. Conclusion: The purse-string suture technique presents a more natural breast silhouette around the NAC and helps to maintain nipple projection. Furthermore, it does not require any supplementary incisions or complicated skills. There has been no report of additional complications using this technique.
Background Thoracodorsal vessels (TDVs) and internal mammary vessels (IMVs) have both been widely employed as recipient vessels for use in free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps. However, whether TDVs or IMVs are preferable as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap remains controversial. The purpose of this study was to compare the clinical outcomes when TDVs were used as recipient vessels to those obtained when IMVs were used as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap. Methods A retrospective matched-cohort study was performed. We retrospectively reviewed data collected from patients who underwent a free MS-TRAM flap for autologous breast reconstructions after mastectomy between March 2003 and June 2013. After a one-to-one matching using age, 100 autologous breast reconstructions were selected in this study. Of the 100 breast reconstructions, 50 flaps were anastomosed to TDVs and 50 to IMVs. Patient demographics and clinical outcomes including operation time, length of hospital stay, postoperative complications, and aesthetic score were compared between the two groups. Results No statistically significant differences were found between the two groups in patient demographics and clinical outcomes, including the complication rates and aesthetic scores. There were no major complications such as total or partial flap loss in either group. Conclusions The results of our study demonstrate that both TDVs and IMVs were safe and efficient as recipient vessels in terms of the complication rates and aesthetic outcomes.
Transverse rectus abdominis muscle (TRAM) free flap is widely used for breast reconstruction, however donor-site morbidities such as abdominal wall weakness, hernia, bulging are troublesome. For the purpose of minimizing donor-site morbidity, there has been a surge in interests in muscle sparing free TRAM flap preserving the anatomy of rectus abdominis muscle, fascia, and motor nerve. The purpose of this study is to investigate complication and morbidity after muscle sparing free TRAM flap. Between August, 1995 and May, 2003, there were 108 cases of muscle sparing free TRAM flap of breast reconstruction. There was no abdominal hernia. There were 4 cases of dog ear, 3 cases of marginal necrosis of apron flap, 2 cases of asymmetry of umbilicus. At 1 year after operation, most patients feel comfortness in physical exercise. Muscle sparing free TRAM flap provides ample amount of well vascularized soft tissue with small inclusion of rectus abdominis muscle and fascia. Also it minimizes donor-site morbidity with rapid recovery of abdominal strength.
Purpose: Skin-sparing mastectomy(SSM) with immediate breast reconstruction is becoming a proved option for early-stage breast cancer patients. Recently, skin-sparing mastectomy with preserving the nipple-areolar complex is becoming popular procedure. Methods: During a 13-month period, from April 2004 to January 2005, 101 cases of immediate breast reconstructions with pedicled TRAM flap were performed after 40 cases of nipple-areolar sparing mastectomies, 57 cases of skin-sparing mastectomies and 4 cases of modified radical mastectomies. Results: During the 11 months follow up period, necrosis of mastectomy skin flap occurred in 17.5%(n=10) after skin-sparing mastectomy and necrosis of mastectomy skin flap and nipple-areolar necrosis occurred in 30%(n=12) after nipple-areolar sparing mastectomy. These complications were healed after simple dressing without any surgical procedure. Conclusion: Nipple-areolar sparing mastectomy and immediate breast reconstruction with TRAM flap is good option for early breast cancer patients and some modifications are needed to reduce skin necrosis.
