BACKGROUND:  In microvascular surgery, patients often receive unfractionated heparin infusions to minimize risk for microvascular thrombosis. Patients who receive intravenous (IV) heparin are believed to have adequate prophylaxis against venous thromboembolism (VTE). Whether a fixed dose of IV heparin provides detectable levels of anticoagulation, or whether the "one size fits all" approach provides adequate prophylaxis against VTE remains unknown. This study examined the pharmacodynamics of fixed-dose heparin infusions and the effects of real-time, anti-factor Xa (aFXa) level driven heparin dose adjustments...

BACKGROUND:  Microvascular reconstruction of the anterior cranial fossa (ACF) creates difficult challenges. Reconstructive goals and flap selection vary based on the defect location within the ACF. This study evaluates the feasibility and reliability of free tissue transfer for salvage reconstruction of low, middle, and high ACF defects. METHODS:  A retrospective review was performed. Reconstructions were anatomically classified as low (anterior skull base), middle (frontal bar/sinus), and high (frontal bone/soft tissue)...

BACKGROUND:  Lower extremity salvage following significant soft tissue loss can be complicated by lack of recipient vessel for free tissue transfer. We describe our experience in lower limb salvage for patients with no recipient vessels with the use of pedicle, free and cable bridge flaps. METHODS:  A retrospective review from 1985 to 2017 of patients undergoing lower limb salvage using a contralateral pedicle cross leg (PCL) flaps, free cross leg (FCL) flaps, or free cable bridge (FCB) flaps was conducted...

BACKGROUND:  Nerve transfer can be broadly separated into two categories: proximal nerve graft and/or transfer and distal nerve transfer. The superiority of proximal nerve graft/transfer over distal nerve transfer strategy has been debated extensively, but which strategy is the best has not yet been defined. Each technique has its own advantages and disadvantages. However, proximal nerve graft/transfer is still the main reconstructive procedure based on the principle of "no diagnosis, then no treatment...

BACKGROUND:  Venules have been usually neglected in the literature on lymphaticovenular anastomosis (LVA). The aim of this study was to analyze the flow dynamic of recipient venules in LVA and their impact on the surgical outcomes. PATIENTS AND METHODS:  Data from 128 patients affected by extremity lymphedema, who underwent LVA, were collected in two institutions from August 2014 to May 2016. Recipient venules were classified according to their flow dynamic into backflow, slack, and outlet (BSO classification)...

BACKGROUND:  The superficial circumflex iliac artery (SCIA)-based iliac bone flap has yet to be widely used. The purpose of this article is to validate the feasibility of SCIA-based iliac bone flap transfers for reconstruction of small to moderate-sized bony defects. Retrospective outcome comparisons between SCIA-based iliac bone flaps and fibula flaps were made. METHODS:  Twenty-six patients with bony tissue defects underwent reconstructions using either free SCIA-based iliac bone flaps (13) or fibula flaps (13)...

BACKGROUND:  Breast implant placement is the most common method for postmastectomy reconstruction. For patients who develop complications associated with implant-based reconstruction, additional surgeries may be challenging. This study examined implant-based reconstruction failure in patients undergoing salvage with abdominal free tissue transfer. METHODS:  We conducted an Institutional Review Board approved, multicenter retrospective study of patients with implant-based primary breast reconstruction followed by implant removal and subsequent abdominal free tissue transfer between 2006 and 2016...

Just what is the S&T lecture? In the beginning it appeared to be a dubious distinction, another task thrust upon me but different in that I had absolutely no idea what was wanted or would be appropriate. At the least, it seemed reasonable to recite a simple introductory story for what would be an extraordinary conclave. First, an appreciation was due to our dedicated leaders of World Society of Reconstructive Microsurgery (WSRM), who this year (2017) have put together the most extravagant meeting ever, intended to include not just the glamorous but the entire scope of rudimentary reconstructive microsurgery...

BACKGROUND:  Ischemia-reperfusion (I/R) injury is inevitable during free tissue transfers. When the period of ischemia exceeds the tissue tolerance, it causes necrosis and flap failure. The aim of this study was to investigate the effects of adipose-derived stem cells (ASCs) embedded in a collagen type I scaffold on the survival of free skin flaps to counteract I/R injury. METHODS:  Left superficial caudal epigastric skin flaps (3 × 6 cm) were performed in 28 Wistar rats that were divided into four groups...

BACKGROUND:  The lymphovenous anastomosis (LVA) has become one of the treatment options for lymphedema. However, it is regarded as a difficult surgery that many young microsurgeons are reluctant to try. This report investigates the learning curve in regard to symptom improvement. METHOD:  This is a retrospective analysis performed in 33 consecutive lymphedema patients (38 extremities) who underwent only LVAs from August 2010 to February 2016. Surgical outcomes in regard to surgeon's experience were evaluated...

BACKGROUND:  Various techniques have been developed for postburn neck reconstruction, but a treatment algorithm is needed. METHODS:  We retrospectively reviewed all patients treated for postburn neck contracture at our institution between February 2008 and December 2015. Necks were divided into one anterior subunit and two lateral subunits marked by the sternocleidomastoid muscle. Deformities were categorized into three types according to their size and location...

BACKGROUND:  Resection of primary spinal tumors requires reconstruction for restoration of spinal column stability. Traditionally, some combination of bone grafting and instrumentation is implemented. However, delayed healing environments are associated with pseudoarthrodesis and failure. Implementation of vascularized bone grafting (VBG) to complement hardware may present a solution. We evaluated the use of VBG in oncologic spinal reconstruction via systematic review and pooled analysis of literature...

BACKGROUND:  Reconstruction using supermicrosurgery, a technique of microneurovascular anastomosis for smaller vessels (< 0.8 mm), has become popular. Experimental animal studies for supermicrosurgery training have been reported; however, there have been few studies performed according to vessel diameter and pedicle length. In this study, the external diameters of four vessels (femoral, superficial epigastric, axillary, and common thoracic) and pedicle length of two flaps (superficial epigastric and common thoracic-long thoracic) were measured...

BACKGROUND:  Microsurgical free tissue transfer is a popular technique nowadays. Because of its considerably exquisite procedure, various risk factors can affect surgical outcome. However, current key practices, especially those in blood transfusion, are in contention due to the lack of enough evidence. Therefore, the objective of this study was to investigate the impact of perioperative blood transfusion on microsurgical complication. METHODS:  Data of a total of 168 patients who underwent microvascular free tissue transfer from 2013 through 2016 were retrospectively reviewed...

It has been half a century since Susumu Tamai reported on the first thumb replantation. The evolution of reconstructive microsurgery has continually added new applications of the operating microscope for reconstructive surgery and has had profound impact on countless patients. From the time of Harold Gillies until today, the reconstructive ladder has evolved to a reconstructive elevator with the "penthouse" floor being represented by vascularized composite allotransplantation.
