Aortic root aneurysms associated with severe pectus excavatum caused by Marfan's syndrome can be challenging to correct in children. Recent reports suggest single-stage correction of both cardiac and chest wall deformities through a median sternotomy. We report a 9-year-old girl with Marfan's syndrome, an ascending aorta aneurysm, mitral regurgitation, and pectus excavatum, who underwent David's procedure with mitral valve repair and the Nuss procedure to correct the thoracic deformity. This single-stage combined procedure was performed through a left anterolateral thoracotomy...

INTRODUCTION: Pectus excavatum (PE) is the most common deformity of the anterior thoracic wall. The Nuss technique allows the thorax to be reshaped with the aid of a retrosternal metallic bar. The aim of this study is to evaluate and compare the complication rate between the original Nuss technique and a lightly modified approach. MATERIAL AND METHOD: We performed a retrospective single-center observational study based on the medical files of patients operated for PE in the Pediatric Surgery Unit between July 2004 and July 2015...

We present a case of a 25-year-old male patient suffering from severe prolonged pain after uneventful pectus excavatum repair that could be treated successfully by paravertebral nerve radiofrequency thermoablation. The patient was scheduled for a minimally invasive Nuss pectus excavatum repair. Surgical correction was performed under general anesthesia in combination with a thoracic peridural catheter. The immediate postoperative course was uneventful; however, the patient developed severe prolonged bilateral chest wall pain across segments T8 and T9...

BACKGROUND: A safe and effective method of multilevel thoracic pain control remains an elusive goal in patients undergoing the Nuss procedure. The aim of our study was to develop a nonopioid centered approach using a novel regional technique as part of a quality improvement initiative. METHODS: The proposed ultrasound-guided technique positions multi-perforated soaker catheter deep to the paraspinal muscles from T2 to T11. The project was conducted in two phases...

OBJECTIVES: The aim of this study is to present our experience with Nuss bar removal and evaluate potential risk factors. The Nuss procedure requires an operation to remove the bar 2-3 years after the initial correction. Although removal of the bar is generally believed to be safe, perioperative complications including major bleeding can occur. METHODS: All cases involving removal of the Nuss bar done since April 2007 were recorded in a prospective database. Data were collected on the amount of blood loss, the number of diagnostic interventions, operative management and postoperative course...

The Nuss procedure is now the preferred operation for surgical correction of pectus excavatum (PE). It is a minimally invasive technique, whereby one to three curved metal bars are inserted behind the sternum in order to push it into a normal position. The bars are left in situ for three years and then removed. This procedure significantly improves quality of life and, in most cases, also improves cardiac performance. Previously, the modified Ravitch procedure was used with resection of cartilage and the use of posterior support...

Historically, pectus excavatum (PE) was reported to be congenital, but in our experience only 22% are noticed in the first decade of life. Thus far, genetic studies support an autosomal recessive heritability, which coincides with only 40% of our patients having some positive family history, but is also contradictory given a constant sex ratio of 4:1 in favor of males. This inconsistency may be explained by the effect of more than one pectus disease-associated allele. Once the deformity is noticed, it tends to progress slowly until puberty, when rapid progression is often seen...

Patients with pectus excavatum (PE) often describe improvements in exercise stamina following corrective surgery. Studies have investigated the surgical effect on physiological parameters; still, no consensus has yet been reached. Therefore, the aim of this literature review was to describe the cardiac outcome after surgical correction, both at rest and during exercise. In February 2016, a detailed search of the databases PubMed, Medline, and EMBASE was performed. We assessed clinical studies that described cardiac outcomes both before and after surgical correction of PE...

The correction of deep pectus excavatum, with the Nuss procedure, frequently require a series of maneuvers that is inherently dangerous. Herein we describe 10 technical modifications to prevent potential complications. These modified techniques have certain advantages and according to the authors, with these maneuvers the risk of pericardial sac, cardiac injury, bar displacement and complications during the removal of the bar could be markedly reduced.

BACKGROUND: Recently, technical improvement in the ability to measure lung function and the severity of chest deformity have enabled progress in understanding the mechanism of limitations of lung function in pectus excavatum. METHODS: After establishing that most patients with pectus excavatum do have symptoms of exercise intolerance, easy fatigability, and shortness of breath with exertion, lung function has been evaluated by a variety of methods in different centers...

BACKGROUND: Pectus excavatum (PE) is the most frequent anomaly of the anterior chest wall. Before 2001, all patients in Denmark were referred to the plastic and reconstructive surgeon for implantation of a subcutaneous silicone prosthesis, because the modified Ravitch procedure was not used. Since 2001, all patients have been treated with a modified Nuss procedure, which today has become the gold standard for correction of PE. METHODS: From September 2001 to March 2016, 1,713 patients have been operated by a modified Nuss procedure using the short bar at Aarhus University Hospital with a male-female ratio 6:1...

BACKGROUND: For specific therapy to correct pectus excavatum (PE), conservative treatment with the vacuum bell (VB) was introduced more than 10 years ago in addition to surgical repair. Preliminary results using the VB were encouraging. We report on our 13-year experience with the VB treatment including the intraoperative use during the Nuss procedure and present some technical innovations. METHODS: A VB with a patient-activated hand pump is used to create a vacuum at the anterior chest wall...

Repair of pectus excavatum began at the beginning of the 20(th) century before endotracheal intubation was standard practice. Surgeons therefore developed techniques that corrected the deformity using an open procedure via the anterior chest wall. Initial techniques were unsatisfactory, but by the 1930s the partial rib resection and sternal osteotomy technique had been developed and was used in combination with external traction post-operatively to prevent the sternum from sinking back into the chest. In 1949, Ravitch recommended complete resection of the costal cartilages and complete mobilization of the sternum without external traction, and in 1961 Adkins and Blades introduced the concept of a substernal strut for sternal support...

BACKGROUND: Pectus excavatum is the most common congenital chest wall deformity. The two most common surgical techniques for its correction are the modified Ravitch technique and the minimally invasive Nuss technique. Despite both procedures being used widely, data comparing them are scarce. METHODS: We conducted a systematic review and meta-analysis of comparative studies to evaluate these procedures. A systematic search of the literature was performed from six electronic databases...

BACKGROUND: Multimodal pain management strategies are used for analgesia following pectus excavatum repair. However, the optimal regimen has not been identified. We describe our early experience with intercostal cryoablation for pain management in children undergoing the Nuss procedure and compare early cryoablation outcomes to our prior outcomes using thoracic epidural analgesia. METHODS: A multi-institutional, retrospective review of fifty-two patients undergoing Nuss bar placement with either intercostal cryoablation (n=26) or thoracic epidural analgesia (n=26) from March 2013 to January 2016 was conducted...

PURPOSE: The aim of this study was to compare the functional exercise capacity and the lung function among patients undergoing early rehabilitation with those submitted to the conventional care after pectus excavatum repair using the Nuss procedure. METHOD: Patients were randomly allocated to the early rehabilitation group (ERG) who started rehabilitation after surgery and the group of the conventional care (CG) received routine care of the institution. They were evaluated before surgery (preoperative) and in hospital discharge day (postoperative)...

A facile light-mediated preparation of small palladium nanoparticles (PdNPs) with a diameter of 1.3 nm and low dispersity by using low-priced and readily prepared photoactive polymers is presented. These polymers act as reagents for the photochemical reduction of Pd ions and they are also stabilizers for the PdNPs generated in situ. The PdNP-polymer hybrid materials prepared by this reliable approach are efficient hydrogenation catalysts that show high activity and Z-selectivity in the semi-hydrogenation of alkynes...

INTRODUCTION: Although dyspnea with exercise in the pediatric population can be multifactorial, the diagnosis of paradoxical vocal fold motion disorder (PVFMD) in this group is not well characterized. The objective of this study is to review the multiple causes of dyspnea with exercise in children, including the prevalence of PVFMD within this study population. METHODS: A retrospective review was conducted of patients seen at a tertiary pediatric hospital for exercise-induced dyspnea suspected to be related to PVFMD between January 2007 and July 2015...

Diseases of the bovine digit remain the major cause of painful lameness in cattle and commonly constitute a diagnostic and therapeutic challenge for clinicians. Prompt surgical wound revision is critical in acute injuries. Deep infections may be treated with debridement, resection of tendons, synovioscopy, joint lavage, arthrotomy and facilitated joint ankylosis. Postoperative care is more involved, lameness persists longer, and cost of treatment is higher after salvage techniques than after amputation of the digit...
