Impact of the Prepectoral Breast Reconstruction Assessment Score on Expander-Based Reconstruction Success.

Background/Objectives: The rising incidence of breast cancer has led to more mastectomies and increased demand for reconstruction. While retropectoral reconstruction with expanders is common, it has complications like postoperative pain and animation deformity. Prepectoral reconstruction, aided by advancements in biological and synthetic meshes, offers a promising alternative. Methods: This study prospectively evaluated the "Prepectoral Breast Reconstruction Assessment Score" on 20 patients undergoing mastectomy at Policlinico Umberto I, Rome, from July 2022 to February 2024. Patients with scores between 5 and 8 were included. The procedure involved the use of ADM (Acellular Dermal Matrix) or titanium-coated polypropylene mesh, followed by postoperative expansions and final implant placement after six months. Results: The mean age of patients was 51.85 years, with a mean BMI of 24.145 kg/m2. ADM was used in 15 cases and synthetic mesh in 5. Complications were one exposure of the expander, one superficial skin necrosis and one seroma. Statistical analysis showed a trend toward fewer complications with higher scores, though this was not statistically significant (p-value = 0.139). Conclusions: Prepectoral reconstruction with expanders is a viable option, offering benefits such as reduced operating time, better volume control, and a more natural breast contour compared to the retropectoral approach. Although the trend suggests fewer complications with higher assessment scores, further studies with larger samples are needed for confirmation.

Infrahyoid myocutaneous flap for reconstruction in head and neck cancer patients

Background: Reconstruction of head and neck defects following tumor excision is one of the most challenging surgeries due to multiple reasons, such as associated cosmetic and functional impairments. The three-dimensional aspect of the defect makes it more difficult. Although in modern settings, microvascular surgery is preferred in many conditions, it requires the presence of resources and expertise. Locoregional flaps are workhorse flaps in head and neck reconstruction. In this article, we present an uncommonly used flap with high acceptability and success rate in head and neck reconstruction. Aim: To find outcomes of using infrahyoid flap reconstruction in head and neck defects following cancer excision. Materials and Methods: The retrospective study was conducted in the surgical oncology department of our institute. Patients with squamous cell carcinoma of the oral cavity, clinically T1–T3 and N0–N1 stage, with anticipated defects of small to medium defects were included in the study. The study was conducted from July 2020 to June 2022, including a follow-up of 1 year. A total of 14 patients were included in the study. All patients had squamous cell carcinoma of the oral cavity involving different subsites. Patients were operated on by a single surgeon, using the same technique. Result: A total of 14 patients were included with a male-to-female ratio of 11:3 and age between 45 and 60 years. None of the patients underwent revision surgery, and none of the patients had total flap loss. Four patients had minor flap complications, of which three patients had partial, superficial skin necrosis of the flap which was managed conservatively and epithelized later. None of the patients developed major complications, oro-cutaneous fistula, or radiation necrosis. None of the patients developed recurrence after 1 year of surgery. Conclusion: The infrahyoid myocutaneous flap (IHF) is a fairly reliable and easy-to-perform flap for small- and medium-sized defects of the oral cavity, without requiring additional incisions and donor site reconstruction.

Superficial skin necrosis as a rare complication of inferior alveolar nerve block in Egyptian child: A case report

AbstractAimThe aim of the presented case report was to report a rare complication of Inferior Alveolar Nerve Block (IANB) in a 5‐year‐and‐4‐month‐old child and to discuss the possible complications.Materials and MethodsFive years and four months old Egyptian male child presented in paediatric dentistry practice complaining of pain in the lower right primary molars that kept him awake all night. Examination revealed decayed lower right primary first and second molars and the treatment plan was designed to include a pulpectomy procedure for tooth 85 and a pulpotomy procedure for tooth 84. Administration of 1 mL of arctician 4% with 1:100,000 epinephrine anaesthetic solution using the inferior alveolar nerve block technique was done uneventfully. Then, the dental procedure was done as usual. The next morning, the child presented to the dental practice with a non‐painful change in colour in the lower part of the child's right cheek, with small scanty blisters.ResultsThe possible causes of such a complication and the proper management are discussed in this article with a confirmation of the superficial skin necrosis as the most possible cause.ConclusionAlthough proper awareness of the anatomical structures of the orofacial region along with meticulous administration technique of local anaesthesia is mandatory for the everyday dental practice, the dentist may face possible, sometimes rare complications of local anaesthesia and he should be able to manage them probably.

Treatment of Complex Central Talar Fractures with Lateral Plate Combination with Medial Screw Fixation.

The treatment of talar neck and/or body fractures is known to be difficult and challenging, with significant impact on the long-term functional outcome for the patient. The optimal management, including the choice of surgical approaches and implants, are still under constant discussion. The purpose of the study was to investigate the clinical effects of lateral mini-plate combined with medial lag screws for the treatment of complicated central talar fractures. The data of eight patients with complex central talus fractures treated between June 2019 and January 2021 were retrospectively analyzed. There were six males and two females, ranging in age from 15 to 66 years, with an average age of 37.4 years. There were three cases on the left and five cases on the right. All fractures were comminuted, including talar neck with talar body fracture in seven cases and talar body comminuted with subluxation of subtalar joint in one case. All patients were treated with the anteromedial combined anterolateral approach, lateral talar mini-plate fixation and medial lag screw fixation. Fracture reduction quality, union time, and complications were recorded, and functional outcomes were evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) scoring system. The time from injury to surgery was 1-6 days, with an average of 3.38 days. The follow-up period was 34-53 months (mean 44.88 months). All fractures healed with a mean healing time of 16.75 weeks (13-23 weeks). Anatomical reduction was observed in six cases and near in two cases. After operation, there was no loosening or breakage of implant, loss of fracture reduction, and irritation of skin and soft tissue by internal fixation. The average AOFAS score was 87.38 (48-100), with excellent five cases, good two cases and poor one case, and the excellent and good rate was 87.5%. Superficial skin necrosis in one surgical incision healed after dressing exchange. No deep infection occurred. One case (1/8, 12.5%) developed avascular necrosis of the talus without collapse. Posttraumatic arthritis was found in four cases (4/8, 50%). The utilization of lateral mini-plates in combination with medial screws for treating complex central talar fractures results in satisfactory reduction and stable fixation, mitigating complications associated with poor reduction. However, due to the absence of an anatomical mini-plate, pre-contouring is necessary when applying the lateral plate. This demands a surgeon's thorough familiarity with the anatomical morphology of the talus and proficiency in surgical techniques. Posttraumatic arthritis is the most common complication of complex central talar fractures.

Mid-term prognosis of endoscopic debridement combined with percutaneous cutaneo-fascial suture for the treatment of Morel-Lavallée lesion: a minimum 3-year follow-up study

PurposeMorel-Lavallée lesion (MLL) is a closed soft-tissue degloving injurie resulting from shear forces. With the advent of endoscopic technology and advancements in surgical techniques, innovative solutions are now available. However, there are few data on mid-term results after treatment of MLL, especially regarding arthroscopic method. The objective of this study is to evaluate the clinical outcomes of endoscopic debridement combined with percutaneous cutaneo-fascial suture in treating MLL. MethodsA single-center retrospective study was conducted at a university teaching hospital investigating patients who underwent arthroscopic management of Morel-Lavallée lesion between 2014 and 2020.Patient demographics, postoperative recovery time, peri- and postoperative complications were investigated. Mid-term follow up clinical and radiological examinations were performed. ResultsThe retrospective study included 38 patients aged between 11 and 90 years, with an average age of 50.9 ± 16.9 years. These patients waited an average of 36.6±23.5days to return to work after operation. The average time to follow-up was from 3 to 9 years, averaging 5.0 ± 1.8 years. At the end of follow-up, only one complication of superficial skin necrosis occurred, accounting for 2.6%. The imaging assessment at the final follow-up indicated improvement over the postoperative period for all 38patients. ConclusionIn mid-term experience, endoscopic debridement combined with percutaneous cutaneo-fascial suture for MLL management is a safe and effective option.

Direct fixation of posterior malleolus fractures-posterolateral or posteromedial approach?

Ankle fractures involving the posterior malleolus (PM) generally have worse prognosis. There is a trend towards it's direct fixation, yet the exact indications are a subject of debate. The purpose of our study was to present our treatment protocol and to discuss the advantages and limitations of the direct posterolateral and posteromedial approaches. We present a prospective series of 35 ankle fractures involving the PM, operated for a period of 4 years (2018-2022). Direct posterolateral approach was used in 20 ankles, 15 were operated via a posteromedial approach. Clinical and functional assessment was performed according to the criteria of AOFAS. 14 patients received an excellent score, 16 had good and the rest had an average score. The overall score was 85,4 (54-100). The average range of motion was 50° (15°-55°).Eight patients had superficial skin necrosis along the surgical incision. Thirteen patients need their fibular plates removed due to local irritation. Five patients, operated through a posterolateral approach, had lateral heel numbness suggestive of a sural nerve disfunction. PM is important for normal ankle kinematics. When it's direct fixation is considered appropriate, the safest and shortest route is optimal. It is determined by the preoperative CT. The posterolateral approach is more versatile, but lead to more complications in our study.

Application of Facial Artery Perforator Flap in Nasal and Perinasal Reconstruction.

This paper reports the results of an observational study in 23 patients to evaluate the application of the facial artery perforator flap in nasal and perinasal reconstruction after skin cancer surgery. In the long term, all flaps survived, and the patients achieved satisfactory esthetic reconstruction without functional alterations or major complications. Immediately postoperatively, 2 flaps presented early venous congestion, and 1 had minor superficial skin necrosis that healed without additional intervention. In 3 cases, it was combined with a second simultaneous local flap for synchronous or extensive skin tumors. The facial artery perforator flap is a reliable and versatile option that can be considered the preferred alternative for single-stage restorations of complex small to medium-sized nasal and perinasal defects that allow reconstruction of both external and internal nasal structures.

Embolo/sclerotherapy for the treatment of hand arteriovenous malformations: a single-center retrospective cohort experience.

To retrospectively report our preliminary experience of treating hand arteriovenous malformations (AVMs) with embolo/sclerotherapy. Retrospectively review the demographics, treatment detail, outcome data, and complications of 13 consecutive patients with hand AVMs from January 2018 to December 2021. We embolize the dominant outflow vein with elastic coils and then use absolute ethanol or polidocanol for intravascular sclerotherapy and bleomycin for interstitial sclerotherapy. Yakes type II presents in four lesions, type IIIa in six, and type IIIb in three. A total of 29 treatment episodes were conducted for the 13 patients (1 episode for 3 patients, 2 for 4 patients, and 3 for 6 patients; the repeated treatment rate was 76.9%). The mean stretched length of coils for 1 treatment episode was 95 cm. The mean absolute ethanol dosage was 6.8 ml (range 4-30 ml). In addition, 10 ml of 3% polidocanol foam was injected and interstitial sclerotherapy with 150,000 IU bleomycin was performed on every patient. The post-operative arterial-dominant outflow vein pressure index (AVI) increased in the 29 procedures (6.55 ± 1.68 vs. 9.38 ± 2.80, P < 0.05). The Mann-Whitney U test showed that the post-operative AVI was higher in patients without re-intervention (P < 0.05). Local swelling occurred after all the procedures. Blistering occurred in 6 of the patients in 13 (44.8%) of the 29 procedures. Superficial skin necrosis occurred in 3 of the patients in 5 (17.2%) of the 29 procedures. The swelling, blistering, and superficial skin necrosis recovered within 4 weeks. No finger amputation occurred. The follow-up time was 6 months. The 6-month assessment of clinical improvement after the last treatment episode showed that 2 patients were cured, 10 were improved, and 1 remained unchanged. With regard to angiographic evaluation, 9 showed partial response and 4 complete response. Embolo/sclerotherapy can be effective and safe for hand AVM. The AVI increased significantly after embolo/sclerotherapy, and the index may be valuable in predicting recurrence in further study.

Water-Tight Arthrotomy Joint Closure of Modified Intervastus Approach in Total Knee Arthroplasty.

The joint closure technique used for total knee arthroplasty cases can have an impact on outcomes, especially when considering accelerated rehabilitation programs that follow surgery. In this study, we describe the details of the technical steps involved in performing the water-tight arthrotomy joint closure technique that we developed and use. A total of 536 patients (average age: 62 years, average body mass index: 34 kg/m2) with primary osteoarthritis of the knee underwent total knee arthroplasty using the modified intervastus approach between 2019 and 2021. We used the water-tight arthrotomy joint closure technique to close the knee arthrotomy incision. Any infections and complications, as well as the duration of surgery and cost related to this wound closure technique, are also reported. Few complications were noted with this closure technique. When we first started using it, there was one case of drainage through the proximal capsular repair which required a return to the operating room 5 days postoperatively for an irrigation and debridement. We also had two cases of superficial skin necrosis along a small part of the incision line which were observed on a weekly basis and which healed uneventfully with application of betadine once daily on the necrotic area. The average time for performing wound closure after total knee arthroplasty was 45 min. We conclude that the water-tight closure approach can achieve very durable, water-tight capsule repairs and results in a decrease in postoperative wound drainage.

A Comparative Study Between Mastectomy Flap Quilting Sutures with Axillary Drain Versus Conventional Sutures with Axillary and Pectoral Drain in Reducing Post-Modified Radical Mastectomy Seroma Formation.

The aim of this study was to compare quilting suture with axillary drain versus conventional sutures with axillary and pectoral drain on the formation of seroma after modified radical mastectomy with axillary lymph node dissection. The study was undertaken among 90 female patients with breast cancer who were candidates for modified radical mastectomy with axillary clearance. The intervention group (N = 43) with quilting and axillary drain placement and the control group (N = 33) without quilting with axillary and pectoral drain placement. All the patients were followed up for complications pertaining to this procedure. There were no significant differences between the two groups with regard to demographic characteristics, comorbidities, pre-operative chemotherapy, post-operative pathological findings, lymph node involvement or clinical staging. The incidence of seroma formation on follow-up was significantly lower in the intervention group than that in the control group (23% versus 58%; p < 0.05) whereas there was no significant difference with respect to flap necrosis, superficial skin necrosis and wound gaping between the two groups. Furthermore, it took a shorter duration for seroma to resolve in the intervention group (4days versus 9days; p < 0.001) with a smaller duration of hospital stay (4days versus 9days; p < 0.001). The use of quilting sutures for flap fixation in order to obliterate dead space post-modified radical mastectomy with placement of axillary drain significantly reduced seroma formation along with shorter duration of wound drainage and a smaller hospital stay with only slightly increased operative time. Therefore, we recommend quilting of flap as a routine step after mastectomy.

Complications and Long-Term Outcomes After Prosthetic Capsule Replacement in 15 Dogs with Traumatic Hip Luxation.

Complications and long-term clinical outcomes for 15 dogs surgically treated for traumatic craniodorsal hip luxation by prosthetic capsule replacement (PCR) with a prosthetic ligament were retrospectively reviewed. A PCR technique with capsulorrhaphy was performed in all dogs using acetabular screws with washers and a femoral tunnel as anchor points for the polyester prosthetic ligament. A non-weight-bearing sling was not placed. Minimum 1 yr follow-up period was required for study inclusion. Two major complications (13.3%) consisting of craniodorsal hip reluxation (n = 1) and capital physeal fracture (n = 1) were observed. Minor complications (superficial skin necrosis) occurred in one case (6.7 %). The patient with craniodorsal hip reluxation underwent femoral head and neck ostectomy and was excluded from long-term analysis. In the 11 cases that returned for long-term (median, 3.8 yr; range, 19-75 mo) evaluation at the authors' institution, 10/11 of the dogs were clinically sound. Three dogs did not return for long-term evaluation. However, telephone interview with owners minimum1 yr after surgery indicated normal limb function and absence of complications in all three cases. These results suggest that PCR with polyester prosthetic ligament can be successful in maintaining hip reduction in dogs with craniodorsal hip luxation.

Ventral hernia repair in conjunction with LIPO-ABDOMINOPLASTY in overweight patients: A comprehensive approach.

Repair of large midline ventral hernias still represents a challenge for general surgeons. As obesity is a key factor of this type of hernias, usually the patients are presented with abdominal wall laxity, excess skin and subcutaneous fat. Combined procedures has evolved over the last six decades to repair the hernias and to improve the shape of the abdomen, but was associated with high rate of wound complications. The components separation technique for ventral hernia repair was introduced in 1990 by Ramirez et al to avoid mesh repair was associated with a high rate of success. Until recently, the convenience of simultaneously performing ventral hernia repair and abdominal contouring surgery remains controversial. The aim of this study is to present our experience in the integration of the anterior component separation technique for repair of midline wide ventral defects, with the lipoabdominoplasty in selected patients with high body mass index, to achieve a functional abdominal wall repair and to provide a better aesthetic outcome. In this prospective case-control study, 15 adult female multiparous women, all were overweight and obese, presented with midline ventral hernias and abdominal deformity was operated upon where a comprehensive technique in the form of herniorapphy, anterior component separation technique and lipoabdominoplasty were performed. The patients were followed up for 3-6 months period to monitor incidence of complications, hernia recurrence and to assess the aesthetic outcome. All the 15 patients were overweight and obese with BMI ranged between 26.5 and 39.6 kg/m2 . The mean operative time was 184 ± 28.8 minutes (range 150-240 minutes). The mean postoperative length of hospital stay was 3 days ranging from 1 to 5 days. In addition to the hernia, all the patients suffered from diastasis of recti ranged from 9 to 15 cm in the transverse dimension. No mortality or major complications encountered, no hernia recurrence, only minor complications occurred in four patients (26.8%). Two patients developed seroma which resolved by aspiration, one patient suffered wound infection with partial loss of the umbilicus and one developed superficial skin necrosis at the central area of the flaps which healed uneventfully by secondary intention. All the patients were satisfied with the cosmetic outcome. In conclusion, this comprehensive approach is effective technique for reconstruction of large midline ventral defects and provide a good aesthetic appearance of the anterior and lateral abdomen in appropriately selected obese patients.

A Single-Center Experience With Gynecomastia Treatment Using Liposuction, Complete Gland Removal, and Nipple Areola Complex Lifting Plaster Technique: A Review of 448 Patients.

Gynecomastia is defined as a benign enlargement of male breast glandular tissue. It is the most common breast condition in male, and the prevalence ranges from 32% to 72%. No standardized treatment exists for gynecomastia. The authors treat gynecomastia patient with liposuction and complete gland excision through periareolar incision without skin excision. In case of skin redundancy, the authors use their special technique called nipple areola complex (NAC) plaster lift technique. The authors conducted the retrospective analysis of patient who underwent gynecomastia surgery between January 2020 and December 2021 at Chennai Plastic Surgery. All patients were treated with liposuction, gland excision, and NAC lifting plaster when required. The follow-up period ranges from 6 to 14 months. A total of 448 patients (896 breasts) were included in our study with average age of 26.6 years. Grade II gynecomastia was most common in our study. The average BMI of the patients was 27.31 kg/m2. One hundred and sixteen patients (25.9%) experienced some form of complication. Seroma was most common complications in our study followed by superficial skin necrosis. Patient satisfaction rate was high in our study. Gynecomastia surgery is safe and highly rewarding procedure for surgeons. Various technologies and methods like liposuction, complete gland excision, and NAC lifting plaster technique should be adopted in gynecomastia treatment to give a better patient satisfaction. Complications are common in gynecomastia surgery but easily manageable.

Early Adverse Effects of Foam Sclerotherapy for Varicose Veins: An Experience of 50 Sclerotherapy Sessions

Background: Foam injection sclerotherapy for treating varicose veins is a newly emerging and minimally invasive technique. Its safety profile needs to be investigated. Objective: We documented the adverse effects associated with foam injection sclerotherapy occurring in the first 24 hours and then at 2 and 4 weeks of follow up visits. Material and Methods: This cross-sectional study was conducted at Department of Surgery in Benazir Bhutto Hospital, affiliated with Rawalpindi Medical University, Rawalpindi from 1st July 2021 till 30th June 2022; on 50 patients of varicose veins. A duplex ultrasound was done in all patients. Varicose veins were classified using the CEAP system. Patients having C1 and/or C2 varicose disease with isolated GSV incompetence on duplex ultrasound were included. Results: Only minor complications were encountered and no serious complication was seen. The minor side effects included nausea, hyperpigmentation, matting, headache, vomiting, pruritus around injection site, vomiting and shortness of breath. Serious complications like anaphylactic shock, stroke, TIA, deep venous thrombosis, superficial venous thrombosis, tissue necrosis and skin necrosis were not encountered in any patient. Conclusion: Injection sclerotherapy with sodium tetra decyl sulphate in the foam form for the treatment of varicose veins is a safe modality; since only minor complications were encountered and no serious complication was seen.

Displaced paediatric distal radius fractures with volar skin tenting following manipulation and reduction: a report of two cases and literature review

Distal radius fractures are amongst the most common forearm fractures in children and can often be managed with closed reduction and casting for the majority of patients. While the thick periosteum sleeve can be used to guide reduction, it can also make the traction used in an adult patient counterproductive to closed reduction attempts. We report two unusual cases of distal radius fractures with displaced volar fragments in children that required urgent surgical intervention following manipulation and reduction due to concern for skin and neurovascular compromise. While one patient developed post-operative superficial skin necrosis managed conservatively, both children recovered well without long-term complications.

Direct Fixation of Fractures of the Posterior Malleolus Through a Postero-Medial Approach

Abstract Background and objective: Fractures of the posterior malleolus have long been neglected in the past. The decision for their fixation should be based on plain lateral radiographs. Recent studies have emphasized the important biomechanical function of the posterior tibial ridge. This has caused a trend towards more aggressive surgical treatment. The aim of this study was to present our experience with the direct fixation of complex ankle fractures engaging the posterior malleolus. We also tried to clarify the advantages and limitations of the posterior-medial surgical approach. Materials and Methods: For a period of 1,5 years we have operated 14 patients with posterior malleolus fractures. Their average age was 51 years. Eight of the patients were male, the rest 6 were females. Fractures were classified according to Bartoníček classification system. All patients had type 3 fractures. Direct open reduction was performed in all cases. Posterior buttress plate was used for the fixation of the fracture. Bone grafting was found necessary in one case. Functional assessment was done according to the criteria of the AOFAS (American Orthopedic Foot and ankle score). Follow up was done for an average period of 10 months. Results: All fractures united for an average period of 9 weeks (8-10 weeks). Six patients achieved an excellent functional result, 5 – a good one and 3 had an average result. The average AOFAS rating score was 84,02 (54-100). The average range of motion was 38° (15°-50°). There were no deep infections or septic arthritis. Three ankles had superficial skin necrosis that healed without any additional procedures. One patient had prolonged and substantial swelling of the leg, despite of the routine antithrombotic prophylaxis. Five patients needed their fibular plates removed due to local irritation. Conclusion: The direct reduction and fixation of the posterior malleolus fractures allow anatomical restoration of the ankle mortise. This is a prerequisite for an optimal functional recovery and appears to be a safe treatment strategy.

Complications in surgical management of calcaneal fractures with anatomical plates

&lt;p class="abstract"&gt;&lt;span lang="EN-US"&gt;Calcaneal fractures, irrespective of their types, are treated non-operatively, one of the reasons being fear of complications. But conservatively managed fractures can result in equally problematic complications. Incidence of subtalar arthritis in such cases is reported to be 16.9% compared 3.3% in cases treated surgically. With surgical treatment aimed at achieving anatomical joint reduction, regaining calcaneal height, its length and width, successful attempts at curtailing the long-term complications can be made. This was a prospective study of 20 cases of calcaneal fractures, admitted to MNR Medical College and Hospital, Sangareddy from August 2020 to September 2021 were treated with ORIF with non-locking anatomical calcaneal plates using Fernandez’s approach, without use of bone graft. Essex Lopresti and Sander’s classification were used. Intra-operative assessment of reduction and articular surface reconstruction was done under fluoroscopic guidance. Regular follow up was done for assessment of fracture union and complications, assessment of late collapse. Among the 20 cases, 73% were men and 27% women. On typing the fractures based on Essex-Lopresti classification, intra-articular tongue type constituted 13% and 87% were of joint depression. Near normal anatomical reduction was obtained in all cases except in one where it was difficult due to comminution noted during surgery. 2 cases developed superficial skin necrosis at the surgical site, 1 case of deep infection and abscess formation and 3 cases of subtalar arthritis. This study showed that the incidence of long-term complications can probably be minimized by restoring the altered anatomy through surgical means; hence we advocate surgical management and accurate anatomical reduction in cases of displaced and comminuted calcaneal fractures with proper surgical principles. &lt;/span&gt;&lt;/p&gt;

The Assessment of Postoperative Patency and Flow Pattern of Twisted Vascular Pedicle in Propeller Perforator Flaps in Lower Extremities Reconstruction

Abstract Background The propeller perforator flap is a variant of perforator flaps in which complete skeletonization of the perforator with venae commitantes is done to transfer the islanded flap on its pedicle with up to 180 degrees of twisting that predispose to its gradual occlusion by time. These flaps have been recently advocated for lower extremity reconstruction. However, reconstruction of the lower extremity especially in the distal third of the leg quite often involves multistage procedures that might necessitate flap re-elevation and little knowledge is available about postoperative patency of these flaps. Aim of the work The aim of this study is to assess the postoperative patency and flow pattern in twisted vascular pedicle of propeller perforator flaps used in lower extremity reconstruction. Materials and methods A Prospective study was conducted on 15 patients 18 years or older of both genders undergoing lower extremity soft tissue reconstruction by propeller perforator flaps rotated from 90 to 180 degrees at Ain Shams University Hospitals and Nasser Institute between 1st February and 31th December 2019. With exclusion of smoking, peripheral vascular diseases and diabetes mellitus, each patient was evaluated preoperatively in regards to age, gender, comorbidities, bacterial contamination or infection, cause of tissue loss. The flap size, source vessel, arc of rotation, donor site closure was analyzed. The flow pattern was evaluated by handheld Doppler device and used as a control for the study. Postoperatively, the same handheld Doppler device was used to localize the vascular pedicle, evaluate its patency and assess the flow pattern at a minimum follow up period of 3 months postoperatively in all patients. Results The mean age of the fifteen patients included was 35.3 years old. Six patients lost tissue was caused by unstable scar, while post-traumatic in the remaining. Preoperatively, four patients had osteomyelitis and four had wound infection. The rest of patients did not report any infection. Eight out of fifteen patients used perforators from peroneal vessel source, while seven patients used posterior tibial artery source. Forty percent of included participants had a 180 degrees arc of rotation, while 26.7% of participants had an arc rotation angle of 120 degrees, and 33.3% had 90 degrees. Five patients had early post-operative congestion that improved by conservative methods without de-rotation of the flap, one patient had skin graft loss over the donor site of the flap, and another patient suffered in addition to skin graft loss distal congestion leading to superficial skin necrosis. Eight patients had no complications. All patients had patent vessels with biphasic flow pattern postoperatively at a minimum of 3 months postoperatively. Conclusion The perforator propeller flaps are safe, reliable procedures and are considered as an ideal option in reconstructing small-medium defects of the middle and distal third of the leg providing similar skin texture with low rate of vascular obstruction. The present study documented patent vascular pedicle of propeller perforator flaps at three months postoperatively.

Day-case approach to immediate breast reconstruction: pushing the boundaries of ambulatory breast surgery in the post-COVID-19 era.

Day-case surgery is safe and efficacious for most breast surgical procedures. Limited data exist on its use in immediate breast reconstruction. We present our experience of day-case management of mastectomy with immediate pre-pectoral implant-based reconstruction (IBR). Data were collected on 47 patients who underwent day-case skin-sparing (SSM) or nipple-sparing (NSM) mastectomy with pre-pectoral IBR between October 2017 and September 2019. Clinicopathological data were collected, including postoperative complications, re-admission and re-operation. The data were compared to published national standards. Median age was 52 years (range 37-74). Thirty-two patients (68%) had an SSM and 15 (32%) had an NSM. Two patients (4%) had risk-reducing mastectomies and 45 had treatment for invasive cancer or ductal carcinoma in situ (DCIS). Mean tumour size was 33.3mm (range 7-85mm). Forty-two (89%) patients went home on the day of surgery. No patients required re-operation in the first 48 hours. The median postoperative follow-up time was 11.4 months (range 1.8-22.7 months). During the first 90-day postoperative period, eight patients (17%) developed superficial skin necrosis, five patients (10.6%) developed postoperative infections and five patients (10.6%) suffered an implant loss. Eight patients (17%) were readmitted for re-operation. Compared to UK national standards set in the iBRA study, our cohort has demonstrated comparable postoperative infection, implant loss and re-operation and re-admission rates. We have demonstrated close to 90% day-case success rate for mastectomy with IBR. These early data suggest that immediate IBR can be carried out in a manner that is cost-efficient without impacting surgical outcomes.
