BACKGROUND:  Postoperative microvascular arterial vasospasm is a rare clinical entity. There are no published management algorithms and also the pathophysiology of this phenomenon has not been elucidated. METHODS:  An email survey of American Society for Reconstructive Microsurgery (ASRM) and World Society for Reconstructive Microsurgery (WSRM) members regarding their experiences with postoperative arterial vasospasm was conducted, returning 116 responses. A comprehensive literature search was conducted regarding the current body of knowledge on this entity...

The creation of a neoumbilicus is a common challenge for plastic surgeons. The authors present their technique of umbilical reconstruction with bilateral square "pumpkin-teeth" advancement flaps. The technique described is applicable in both the setting of a vertical midline incision and when no midline incision is present (e.g., an abdominoplasty). The reconstruction has been performed in over 50 patients with a vertical midline incision and five patients without a midline incision. The only complications noted were persistent serous drainage in several patients with vertical incision and inadequate depth in one patient without a midline incision...

BACKGROUND: We sought to evaluate the results of a new mesh sutured repair technique for closure of contaminated incisional hernias. METHODS: 48 patients with contaminated hernias 5 cm wide or greater by CT scan were closed with mesh sutures. Surgical site occurrence, infections, and hernia recurrence were compared to similar patient series reported in the literature. RESULTS: Of the 48 patients, 20 had clean-contaminated wounds, 16 had contaminated wounds, and 12 were infected...

The biocompatibility of prosthetic mesh is dependent on a number of physicochemical properties that ultimately incite an optimal foreign body response (FBR). The magnitude and character of the FBR directly affect the clinical success of the hernia repair, with too little scar resulting in bulge or hernia recurrence and too much scar causing mesh wrinkling and pain. Moreover, it is important to consider the effect of a sustained FBR and scar remodeling on the combined strength of the mesh-tissue construct over time...

Myoelectric devices are controlled by electromyographic signals generated by contraction of residual muscles, which thus serve as biological amplifiers of neural control signals. Although nerves severed by amputation continue to carry motor control information intended for the missing limb, loss of muscle effectors due to amputation prevents access to this important control information. Targeted Muscle Reinnervation (TMR) was developed as a novel strategy to improve control of myoelectric upper limb prostheses...

BACKGROUND: Current ventral hernia repair risk estimation tools focus on patient comorbidities with the goal of improving clinical outcomes through improved patient selection. However, their predictive value remains unproven. METHODS: Outcomes of patients who underwent midline ventral hernia repair with retrorectus placement of mid-weight soft polypropylene mesh between 2010 and 2015 were retrospectively reviewed and compared with predicted wound-related complication risk from 3 tools in the literature: Carolinas Equation for Determining Associated Risk, the Ventral Hernia Working Group (VHWG) grade, and a modified VHWG grade...

Large skeletal defects caused by trauma, congenital malformations, and post-oncologic resections of the calvarium present major challenges to the reconstructive surgeon. We previously identified BMP-9 as the most osteogenic BMP in vitro and in vivo. Here we sought to investigate the bone regenerative capacity of murine-derived calvarial mesenchymal progenitor cells (iCALs) transduced by BMP-9 in the context of healing critical-sized calvarial defects. To accomplish this, the transduced cells were delivered to the defect site within a thermoresponsive biodegradable scaffold consisting of poly(polyethylene glycol citrate-co-N-isopropylacrylamide mixed with gelatin (PPCN-g)...

BACKGROUND: Free and pedicled medial and lateral thigh-based flaps are common reconstructive procedures. However, there have been no comparative studies of morbidity between medial and lateral donor sites. METHODS: We conducted an Enterprise Data Warehouse-based review of all the senior authors' (R.D.G., G.A.D., and M.S.A.) thigh-based free and pedicled flaps. Patient demographic data, donor-site complications, drain duration, and number of postoperative visits were collected and compared...

We present a case of a 66-year-old woman who developed heart failure and severe inflammatory reaction after the illicit cosmetic injections of polymethyl-methacrylate or polyacrylamide hydrogel from a primary care provider. After medical optimization, an en bloc excision of all injectable materials and gluteus muscle was performed, which resulted in exposure of bilateral sciatic nerves. Within 10 days, the patient's heart failure resolved and inflammatory state improved. This is the first known report of heart failure due to buttock injections and subsequent improvement after surgery...

A new closure technique is introduced, which uses strips of macroporous polypropylene mesh as a suture for closure of abdominal wall defects due to failures of standard sutures and difficulties with planar meshes. METHODS: Strips of macroporous polypropylene mesh of 2 cm width were passed through the abdominal wall and tied as simple interrupted sutures. The surgical technique and surgical outcomes are presented. RESULTS: One hundred and seven patients underwent a mesh sutured abdominal wall closure...

BACKGROUND: Our objective was to determine outcomes for complex ventral hernia repairs in a large cohort of patients utilizing an operative construct employing retrorectus placement of a narrow, macroporous polypropylene mesh with up to 45 suture fixation points for force distribution. No consensus exists on the optimal technique for repair of complex ventral hernias. Current trends emphasize large meshes with wide overlaps and minimal suture fixation, though reported complications and recurrence remain problematic...

Burn scar contractures remain a common source of severe disability in resource-limited countries. However, existing outcome measurements are unable to fully capture the impact of the scar contracture and surgical attempts at correction. To that end, we have developed a new outcome instrument, the Stanford-ReSurge Burn Scar Contracture Scale-Upper Extremity that can be used as a measurement of disability and reconstructive procedure outcomes. The outcome instrument was created through item generation, item reduction, and preliminary field testing...

BACKGROUND: The Patient-Reported Outcomes Measurement Information System was used to evaluate the effects of open incisional ventral hernia repair on hernia-related pain. METHODS: All patients who underwent elective repair of a primary or recurrent midline incisional hernia over a 3-year period completed Patient-Reported Outcomes Measurement Information System pain surveys and rated their pain intensity on a visual analogue scale. A retrospective review of these patients was performed...

BACKGROUND: Localized nerve pain in the foot and ankle can be a chronic source of disability after trauma and has been identified as the most common complication following operative interventions in the foot and ankle. The superficial location of the injured nerves and lack of suitable tissue for nerve implantation make this pain refractory to conventional methods of neuroma management. We describe a novel strategy for management using processed nerve allografts to bridge nerve gaps created by resection of both end neuromas and neuromas-in-continuity...

BACKGROUND: Although there is a high incidence of flank defects after lateral abdominal access, there is a paucity of large studies discussing this problem. Most studies express nihilism regarding their surgical management. The goal of this study was to describe the authors' conceptualization of flank defects, with a determination of the number of true hernias versus bulges, and outcomes of surgical repair in these patients. METHODS: The authors carried out a 13-year retrospective review of 31 consecutive flank defects repaired by the senior author (G...

BACKGROUND AND SIGNIFICANCE: The vessels of choice for cerebrovascular high-flow direct bypass procedures are the radial artery and the saphenous vein. Radial artery grafts have become favored over saphenous vein grafts because of higher patency rates and better size matching to appropriate recipient vessels. Radial grafts are prone to spasm however, and this may be seen in 4-10% of cases and can be associated with ischemic sequelae. The standard technique for radial artery harvest calls for complete separation of the artery from its adventitial attachments and associated venous network...
