OBJECTIVE: Oral squamous cell carcinoma (OSCC) is a common type of cancer affecting people worldwide, with still large proportion of patients diagnosed with the disease in the advanced stage. Due to free vascularised tissue transfers, radical cancer treatment and immediate reconstruction are feasible as a one-stage procedure. The aim of this paper is to evaluate retrospectively our experience with free flap reconstruction of oral defects for patients with oral malignancies in advanced stages...

Objective: Multiple factors influence the success of microvascular free flap surgeries. Anaesthesia is an important factor to maximise the success rate of microvascular free flaps both by controlling haemodynamics and improving the perfusion of free vascularised tissue. The debate on the usefulness of regional and general anaesthesia for free tissue transfer is ongoing. This retrospective study was conducted to evaluate the effects of regional anaesthesia and other perioperative factors on outcomes of microvascular free flaps...

Introduction: The superficial veins of upper limbs are seldom talked about. They are always avoided quoting them to be variable in anatomy. Other than the cephalic and basilic veins, no other superficial vein has caught the eyes of anatomists and other health professionals significantly. This article tries to explain the importance of a superficial vein that closely traces the radial vessels and explains its possible use in microvascular reconstruction. Materials and Methods: The forelimbs of 26 upper limbs of fresh frozen cadavers were dissected out...

BACKGROUND: A patent microvascular anastomosis is of paramount importance in free tissue transfer. Anastomotic coupler devices provide an alternative to technically demanding hand-sewn venous anastomosis. Various advantages of these devices have been discussed but previous systematic reviews had methodological flaws or did not perform a meta-analysis. This review aims to evaluate the quality of the evidence and quantify the efficacy and safety of venous couplers compared to hand-sewn anastomosis...

Head and neck surgical reconstruction is complex, and postoperative imaging interpretation is challenging. Surgeons now use microvascular free tissue transfer, also known as free flaps, more frequently in head and neck reconstruction than ever before. Thus, an understanding of free flaps, their expected appearance on cross-sectional imaging, and their associated complications (including tumor recurrence) is crucial for the interpreting radiologist. Despite the complexity and increasing frequency of free flap reconstruction, there is no comprehensive head and neck resource intended for the radiologist...

Background: Some of head and neck cancer patients are in compromised general condition after ablation surgery and chemoradiation therapy, which makes secondary free tissue transfer quite challenging. Elderly cancer patients also have some risk for microvascular surgery with lengthened general anesthesia. In those cases, the pedicled flap vascularized by supraclavicular artery could be considered as an alternative to free flap. Despite several authors have demonstrated the clinical reliability of supraclavicular artery island flap (SCAIF), to date, SCAIF has not been widely used among reconstructive surgeon...

The Surgical reconstruction of defects of the face is challenging. Local and regional flaps have an important part to play, but large defects of bone and soft tissue are a greater problem. Microvascular tissue transfer has become the standard for such patients, and preoperative planning of bony reconstructions is now common. To use these preplanning tools best the implants should be placed in the prosthetically ideal place, and the bone positioned to surround the implants - that is, truly backward planning of the position of the bone...

Although free flap reconstruction has already gained widespread acceptance in pediatric patients, little is known about the outcome of free tissue transfer in head and neck reconstruction in pediatric patients. We present a case of a 6-month-old boy with a large volume deficit in the right temporal fossa after resection of a teratoma. This led to a large volume deficit with widely undermined skin margins. Therefore, we provided volume augmentation by microsurgical free latissimus dorsi myocutaneous flap transplantation...

Eric I Chang, Carrie K Chu, Edward I Chang
The use of preoperative imaging has become routine for many reconstructive microsurgeons to help localize perforators for planning of microvascular free flaps. However, with advancements in imaging technology, perforator mapping represents only one potential benefit as virtual planning and medical modeling, and flap tissue perfusion are also rapidly becoming commonplace and the standard of care for many surgeons who perform high-volume free flap reconstruction for the breast, head and neck, torso, and the extremities...

BACKGROUND:  Recent evidence documenting high success rates following microvascular diabetic foot reconstruction has led to a paradigm shift in favor of more aggressive limb preservation. The primary aim of this study was to examine reconstructive and functional outcomes in patients who underwent free tissue transfer (FTT) for recalcitrant diabetic foot ulcers (DFUs) at our tertiary referral center for advanced limb salvage. METHODS:  Between June 2013 and June 2016, 29 patients underwent lower extremity FTT for diabetic foot reconstruction by the senior author (K...

Given the high stakes for microvascular reconstruction, the majority of reconstructive surgeons have developed paradigms for pre, intra, and postoperative management that have proven to result in individual high success rates. Much has been done to identify and avoid perioperative factors that could potentially increase flap failure rates. Two example of this practice has been the generalized use of anticoagulation in free tissue transfer and the prohibition against vasopressor use in patients that are undergoing free tissue transfer...

Atherosclerosis is a systemic condition that is responsible for many diseases, and becomes a problem in cases where plaques form at several sites. The formation of a thrombotic embolus may jeopardise vascular operations, including microvascular anastomoses in replantation procedures or free tissue transfers. A mobile imaging tool for the detection of thrombosis preoperatively or intraoperatively would be valuable. An intimal injury, simulating removal of atherosclerotic plaques, was made microsurgically in 60 rat aortas, and results were analysed macroscopically, histologically, and with intraoperative indocyanine green (ICG) videoangiography immediately postoperatively...

Miguel de la Parra Marquez, Ricardo Fernandez-Riera
Currently, deep inferior epigastric perforator flap is undoubtedly the first choice for autologous breast reconstruction for most surgeons; however, there are instances where lower abdominal tissue is unavailable for microvascular transfer. In these cases, most surgeons choose gluteal or lower-extremity territories as donor sites.In the setting of morbid obesity, there is an increased risk of flap and donor site complications, as well as increased blood loss, surgical time, and risk of deep venous thrombosis, not to mention a more challenging surgical technique...

Objective To design and implement a postoperative clinical care pathway designed to reduce intensive care usage on length of stay, readmission rates, and surgical complications in head and neck free flap patients. Methods A postoperative clinical care pathway detailing timelines for patient care was developed by a multispecialty team. In total, 108 matched patients receiving free tissue transfer for reconstruction of head and neck defects in the year before (prepathway), year after (early pathway), and second year after (late pathway) pathway implementation were compared based on postoperative length of stay, 30-day readmission rate, intensive care unit (ICU) admission, and rates of medical/surgical complications...
