The warm ischaemia time of microvascular free flaps is limited. Incalculable events, such as lack of adequate recipient vessels or intraoperative medical emergencies, can lead to prolonged ischaemia and potentially to flap loss. In this study, critically perfused ischaemic or congested flaps were temporarily perfused with an extracorporeal perfusion system until anastomosis could be commenced. Temporary extracorporeal perfusion was performed in 8 radial forearm flaps for 147 ± 52 (range 77-237) minutes. Flap perfusion was assessed using Indocyanine Green fluorescence angiography and combined laser Doppler flowmetry and remission spectroscopy...

An accurate and comprehensive understanding of lower extremity arterial anatomy is essential for the successful harvest and transfer of a free fibula osteoseptocutaneous flap (FFF). Minimum preoperative evaluation includes detailed history and physical including lower extremity pulse examination. Controversy exists regarding whether preoperative angiographic imaging should be performed for all patients. Elevation of an FFF necessitates division of the peroneal artery in the proximal lower leg and eradicates its downstream flow...

INTRODUCTION: Successful outcome of any vascularised free flap basically depends upon the successful restoration of circulation in the flap after anastomosis. As the flap ischemic time is the significant factor which determines the outcome of any free flaps, due consideration is given to reduce the time for anastomosis for reperfusion. The present study compares and evaluates whether the usage of microvascular couplers with the conventional suturing reduce the ischemic time of the free flaps...

For patients with malignant disease taking bisphosphonates and denosumab, the incidence of medication-related osteonecrosis of the jaw (MRONJ) is up to 15% in contrast to 0.01% in patients with osteoporosis. Clinical presentation of MRONJ extends from asymptomatic exposure of bone in 94% of patients to severe cases of mandibular fractures in a minority of 4.5%. The strongest risk factors for MRONJ are invasive dental procedures and dental infections. Advances in imaging provide more preoperation information compared with panoramic radiograph...

PURPOSE: Drawbacks of the conventional supraclavicular overlay of the pectoralis major myocutaneous flap (PMMF) include the resultant unesthetic cervical bulge and the limited cephalad extension that limits its use to mandibular or cervical defects. This study discusses the technique and comparative advantages of a more esthetic subclavicular route through the clavipectoral fascia that allows an increased arc of rotation to reconstruct orofacial defects. MATERIALS AND METHODS: Patients with orofacial defects that were reconstructed with a PMMF through the modified subclavicular route were included in this retrospective cohort study, which aimed to compare the gain in extension accorded through the modified subclavicular tunnel over an initial conventional supraclavicular overlay...

PURPOSE: We sought to use the NSQIP database to determine the national rate and predictors of free flap failure based upon flap sites and flap types. METHODS: Free flaps were identified using the 2005-2010 NSQIP database. We examined overall flap failure rates as well as failure rates based upon flap sites (head and neck, extremities, trunk, and breast) and flap types (muscle, fascial, skin, bone, and bowel flaps). Univariate and multivariate analyses were used to determine predictors of flap failure...

BACKGROUND: Breast reconstruction with microvascular free tissue transfer has become a widely used method. Despite a high rate of success, a compromised flap necessitating re-exploration can occur. Here, we introduce direct thrombectomy as a flap salvage technique, and compared the results with conventional thrombectomy. METHODS: A total of 488 patients who underwent breast reconstruction using a free transverse rectus abdominis myocutaneous flap between March 2009 and February 2014 were retrospectively analyzed...

OBJECTIVE: This study aims at selecting recipient vessels for free flap following intra-arterial chemoradiotherapy. At present, many centers combine intra-arterial chemotherapy and concomitant radiotherapy for treating head and neck cancer with favorable results. However, some patients develop recurrent, residual disease/complications after completing treatment protocols and thus require free-flap surgery. The feasibility of microsurgery following intra-arterial chemoradiotherapy remains unclear...

Although great success of microvascular free-flap transplantation surgery has been achieved in recent years, between 1.5% and 15% of flaps are still lost due to vascular occlusion. The clinical challenge remains to salvage a transplant in the case of vascular complications. Since flap loss is devastating for the patient, it is of utmost importance to detect signs of complications or of conspicuities as soon as possible. Rescue success rates highly depend on early revision. In this study, we collected blood samples during transplantation surgery from either the contributory artery or the effluent vein of the flap and applied a targeted mass spectrometry-based approach to quantify 24 acute phase proteins, cytokines, and growth factors in 63 plasma samples from 21 hospitalized patients, generating a dataset with 9450 protein concentration values...

Wound healing complications associated with total knee arthroplasty present a considerable challenge to the orthopaedic surgeon. To ensure preservation of a functional joint, the management of periprosthetic soft-tissue defects around the knee requires rapid assessment, early and aggressive débridement, and durable, contoured coverage. Several reconstructive options are available to tailor soft-tissue coverage to the location, size, and depth of the wound. Special consideration should be given to the timing of the intervention, management of infection, and prosthesis salvage...

: Introduction Achilles tendon and posterior heel wound complications are difficult to treat. These typically require soft tissue coverage via microvascular free tissue transfer at a tertiary referral center. Here, we describe coverage of a series of posterior heel and Achilles wounds via simple, local tissue transfer, called a bipedicle fasciocutaneous flap. This flap can be performed by an orthopaedic foot and ankle surgeon, without resources of tertiary/specialized care or microvascular support...

We describe our experience of cervical lymphadenectomy with microvascular anastomoses involving levels I to V through a minimally-invasive neck dissection. We retrospectively studied 12 patients who had levels I to IV neck dissection with free flap reconstruction between July 2013 and April 2015 at Poole Hospital (male:female ratio 8:4, mean (range) age 66 (49 - 83) years). The mean (range) operating time was 7 (5 - 8) hours, and the total volume drained from the neck was 105 (60-300) ml. The mean (range) number of harvested lymph nodes was 26 (13-39) from levels I to III, and 33 (20-42) from levels I to IV...

Background Topical vasodilators are frequently used during free tissue transfer to prevent and treat vasospasm and microvascular thrombosis. A variety of agents have been studied and are available, yet most microsurgeons select an agent based on anecdotal evidence or personal training. Our aim was to review the literature on topical vasodilators so microsurgeons can make more informed decisions about which agent to use. Methods A systemic review of the literature was performed on PubMed, EMBASE, and Google Scholar using keywords "topical vasodilator," "antispasmodic," "vasospasm," "free flaps," and "microsurgery...

INTRODUCTION: Fibrin sealants have had applications in hemostasis, cohesion, and promotion of healing in plastic surgery. In this article, we review cases where fibrin sealant was used to stabilize microvascular pedicles and compared with previous free flaps performed without fibrin sealant. METHODS: Between 2008 and 2010, 62 consecutive patients underwent free tissue transfer for reconstruction; this involved 33 latissimus dorsi perforator flaps, 14 thoracodorsal artery perforator flaps, 9 latissimus dorsi myocutaneous flaps, 3 lateral thoracic artery perforator flaps, and 3 transverse rectus abdominis myocutaneous flaps, used in head and neck reconstruction, lower limb reconstructions, breast reconstructions, and facial palsy reconstruction...

BACKGROUND: Thrombocytosis in patients undergoing lower extremity free tissue transfer may be associated with a higher risk of microvascular complications. This study assessed whether preoperative platelet counts predict lower extremity free flap thrombosis. METHODS: A multi-institutional retrospective review was conducted on all patients who underwent lower extremity free tissue transfer at Duke University from 1997-2013 and at the University of Pennsylvania from 2002-2013...

Maxillofacial reconstruction surgery largely relies on the use of microsurgical free transfer techniques. Head and neck cancer surgery and ballistic injuries may lead to significant losses of multitissular substances. Even when the free transfer is successful and the microvascular critical phase is resolved, some functions or anatomic structures may not have been properly restored or have worsened. Any plastic surgery technique may be used to improve an unfavorable functional or aesthetic result after free flap reconstruction...
