Adequate surgical resection was required for patients with rib chondrosarcoma. A 61-year-old woman was presented with a palpable chest wall mass. Computed tomography (CT) of the chest revealed an isolated pulmonary nodule about 0.9 cm, and a giant rib tumor about 12 cm × 9 cm which penetrated through the 7(th) rib into thorax. CT reconstruction and simulated surgery was utilized for disease-free surgical margin (R0 resection), then a simultaneous en bloc resection of pulmonary nodule and rib tumor was performed along with chest wall reconstruction under local anesthesia and intravenous sedation without endotracheal intubation...

A 17-year-old previously healthy female presented with a progressive soft tissue infiltrative process involving the neck and thorax. Extensive diagnostic evaluation including multiple imaging, laboratory, and biopsy studies was nondiagnostic. Due to an urgent need to establish a diagnosis and several previous nondiagnostic biopsies, she was referred to interventional radiology for MRI-guided wire localization immediately prior to open surgical biopsy. Under general anesthesia, wires were placed in the areas of increased T2 signal within the bilateral splenius capitis muscles using intermittent MRI-guidance followed by immediate surgical biopsy down to the wires...

An 18-month-old male patient, classified as American Society of Anesthesiologists I, with bilateral inguinal hernia was scheduled for operation. Preanesthetic evaluation revealed history of completed medical treatment of acute bronchitis 10 days ago, and his respiratory examination was recorded as normal. He was successfully operated under general anesthesia with a laryngeal mask. After removal of the laryngeal mask, he displayed signs of hypoxia. Respiratory sounds were undetectable in the left thorax. He was intubated due to failure of adequate ventilation...

BACKGROUND: Acute deterioration in respiratory status commonly occurs in patients who cannot be transported for imaging studies, particularly during surgical procedures and in critical care settings. Transthoracic lung ultrasonography has been developed to allow rapid diagnosis of respiratory conditions at the bedside. Nevertheless, the thorax is not always accessible, especially in the perioperative setting. Transesophageal lung ultrasonography (TELU) can be used to circumvent this problem...

CASE DESCRIPTION A 6-year-old 2.08-kg (4.58-lb) neutered male Lionhead-mix pet rabbit (Oryctolagus cuniculus) was examined because of sneezing and increased respiratory effort. CLINICAL FINDINGS On the basis of the rabbit's radiographic findings, a diagnosis of diaphragmatic retroperitoneal perirenal fat and kidney herniation was made. Nine months later, physical examination revealed increased respiratory rate and effort and slightly decreased body weight. Thoracic radiography revealed decreased lung aeration and further craniomedial displacement of the right kidney, compared with the initial evaluation findings, suggesting progressive herniation of the retroperitoneal perirenal fat...

Migration of orthopedic fixation wires into the ascending aorta though a rare occurrence can have devastating consequences. Therefore, prompt recognition, with immediate and cautious retrieval of the implant is paramount in averting these complications.We present a case of a 5-year-old boy with the intra-aortic migration of a K-wire used for the treatment of a right clavicle fracture. He was transferred to us with a history of syncope, chest pain, and shortness of breath 7 days after K-wire placement, which was performed at another hospital...

BACKGROUND: Lung ultrasound (LUS) is a well-established method that can exclude pneumothorax by demonstration of pleural sliding and the associated ultrasound artifacts. The positive diagnosis of pneumothorax is more difficult to obtain and relies on detection of the edge of a pneumothorax, called the "lung point." Yet, anesthesiologists are not widely taught these techniques, even though their patients are susceptible to pneumothorax either through trauma or as a result of central line placement or regional anesthesia techniques performed near the thorax...

PURPOSE: In vivo radiobiology experiments involving partial body irradiation (PBI) of mice are of major importance because they allow for the evaluation of individual organ tolerance; overcoming current limitations of experiments using lower dose, whole body irradiation. In the current study, the authors characterize and validate an effective and efficient apparatus for multiple animal PBI, directed to the head, thorax, or abdomen of mice. METHODS: The apparatus is made of polymethylmethacrylate and consists of a rectangular parallelepiped prism (40 cm × 16 cm × 8 cm), in which five holes were drilled to accomodate standard 60 ml syringes, each housing an unanesthetized, fully immobilized mouse...

The use of xylazine, a veterinary sedative, with ketamine for rat anesthesia has been shown to enhance the pulmonary capillary hemorrhage (PCH) effect of diagnostic ultrasound. This study was undertaken to assess whether the sedative/analgesic dexmedetomidine, commonly used in the intensive care unit, can also enhance ultrasound-induced PCH. Female Sprague Dawley rats were anesthetized with various combinations of ketamine plus xylazine or dexmedetomidine. The dosage of dexmedetomidine was reduced for some groups to doses relevant to human clinical usage...

Primary tracheal tumors comprise a rare group of benign and malignant tumors. Bronchoscopy is required for diagnosis and staging of tracheal neoplasms as well as debulking of the tumor. The management of anesthesia for rigid bronchoscopy in a patient with tracheal neoplasm presents with many challenges to the anesthetist. We present anesthetic management of an 18-year-old female who presented with orthopnea. Computed tomography scan of the thorax revealed a polypoidal lesion in the trachea proximal to carina and consolidation in the right middle lobe...

Myocardial stiffness and upward-shifted end-diastolic pressure-volume (P-V) relationship (EDPVR) are the key to high filling pressures in heart failure with preserved ejection fraction (HFpEF). Nevertheless, many patients may remain asymptomatic unless hemodynamic stress is imposed on the myocardium. Whether delayed relaxation induced by pressure challenge may contribute to high end-diastolic pressure (EDP) remains unsettled. Our aim was to assess the effect of suddenly imposed isovolumic afterload on relaxation and EDP, exploiting a highly controlled P-V experimental evaluation setup in the ZSF1 obese rat (ZSF1 Ob) model of HFpEF...

Tracheal hypoplasia is commonly seen in English Bulldogs affected with brachycephalic airway syndrome. Previously published diagnostic criteria for tracheal hypoplasia in this breed have been a radiographic tracheal diameter:tracheal inlet ratio (TD:TI) < 0.12 or a tracheal diameter:third rib diameter ratio (TD:3R) < 2.0. Computed tomography has become increasingly used for airway evaluation, however published information is lacking regarding CT tracheal dimensions in English Bulldogs. Objectives of this prospective cross-sectional study were to describe radiographic and CT tracheal dimensions in a sample of clinically normal English Bulldogs and compare these values with tracheoscopy scores...

The aim of this study was to compare the effect of anesthesia with midazolam-fentanyl versus propofol-remifentanil on the BIS (bispectral index) in patients undergoing coronary artery bypass grafting (CABG). Sixty-four patients undergoing CABG were randomly assigned to one of two study groups: midazolam-fentanyl (MF, N=32) or propofol-remifentanil (PR, N=32). The BIS was measured before induction of anesthesia, five minutes after induction of anesthesia, at skin incision, sternotomy, pericardiotomy, aorta cannulation, onset of cardiopulmonary bypass, during rewarming, five minutes after separation from cardiopulmonary bypass, at thorax closure, and at the end of the surgery...

A female northern elephant seal (Mirounga angustirostris) weaned pup presented with malnutrition. During rehabilitation, the seal developed regurgitation and reduced lung sounds on auscultation. Radiographs and endoscopy performed under sedation suggested a diaphragmatic hernia. A Type I (or sliding) hiatal hernia was confirmed with a positive contrast upper gastrointestinal study, revealing varying degrees of herniation of the gastric fundus through the diaphragm into the caudal thorax as well as esophageal reflux...

We present a case of severe isolated congenital diaphragmatic hernia (CDH) diagnosed at 19 weeks of gestation and treated at 28 weeks with Fetal Endoscopic Tracheal Occlusion (FETO). The CDH was left-sided with part of the liver in the thorax and lung area to head circumference ratio (LHR) of 0.9. The FETO was successfully performed under spinal anesthesia. The pregnancy is progressing uneventfully and ultrasound examination 10 days after the FETO demonstrated an increased LHR to 1.1. Treatment with FETO for severe CDH has been performed for the first time in Bulgaria and this procedure addressed several questions for optimal management by an experienced interdisciplinary team...

PURPOSE: Diagnostic laryngoscopy and bronchoscopy (DLB) has been the traditional preoperative diagnostic modality for evaluating presence and severity of tracheobronchomalacia (TBM), and requires anesthesia. Alternatively, multidetector computed tomography (MDCT) is potentially a noninvasive modality that provides high-resolution, 3-dimensional (3D) imaging of the thorax providing preoperative guidance for pediatric surgeons. This study compares MDCT with intraoperative DLB in the assessment of TBM in symptomatic pediatric patients with esophageal atresia (EA)...
