anesthesia mediastinal mass

Mediastinal masses pose one of the great challenges for any anesthesiologist during airway maintenance, underlining the need to devise a well-formulated plan to avoid perioperative complications. As a general rule, such patients are managed with spontaneous ventilation without the use of muscle relaxants and awake intubation. We report a case of a 66-year-old male with severe dyspnea, having a very large invasive anterior mediastinal mass, causing left lung collapse for urgent debulking surgery. The tracheobronchial compromise was ruled out using three-dimensional reconstruction on computed tomography imaging (virtual bronchoscopy) and that helped in using general anesthesia with muscle relaxation for subsequent endotracheal intubation and surgery...

BACKGROUND: Non-intubated thoracoscopic surgery with spontaneous breathing is rarely utilized, but may have several advantages over standard intubation, especially in those with significant cardiopulmonary comorbidities. In this study we evaluate the safety, feasibility, and 3-year survival of thoracoscopic surgery without endotracheal intubation for oncologic and non-oncologic indications. METHODS: All consecutive patients [2018-2022] selected for lung resection or other pleural space intervention under local anesthesia and sedation were compared to a cohort undergoing elective thoracoscopic procedures with endotracheal intubation...

BACKGROUND: Mediastinal tumors pose a challenging respiratory and circulatory management during anesthesia procedures, there is a risk of circulatory collapse or complete airway obstruction, which in severe cases can lead to cardiac arrest. We reported a case of anesthetic management using a bronchial blocker placed outside the tracheal tube. In this case report, the patient's trachea was so severely compressed that the airway was extremely narrow, only 4 mm at its narrowest point...

INTRODUCTION: Thoracic outlet syndrome (TOS) caused by superior mediastinal soft tissue mass has never been reported in the literature, the aim of this study is to discuss a case of TOS caused by a superior mediastinal mass in which the histopathological examinations of the mass showed vascular malformation. CASE REPORT: A 45-year-old female presented with left upper limb pain and numbness for three months, associated with swelling and attacks of shortness of breath...

Mediastinal germ cell tumors (GCTs) are rare. Post-chemotherapy residual masses in patients with a nonseminomatous GCT require resection. A patient with a large mediastinal GCT involving the left subclavian artery, superior vena cava (SVC) and hilum of the right lung is presented. Despite a biochemical response to chemotherapy, the tumor enlarged on serial imaging. With guidance from medical oncology, a multidisciplinary surgical team, including cardiac anesthesia, cardiac surgery and thoracic surgery resected the tumor with a staged reconstruction of the SVC...

RATIONALE: Using an electronic visualized double-lumen endobronchial tube (E-visual DLT) allows for excellent surgical visualization during one-lung ventilation. Situs inversus totalis (SIT) is a rare autosomal recessive genetic condition wherein the bronchial and pulmonary lobar structures on the left and right sides of individuals are reversed compared to those of the general population. In the case of SIT, placing a left-sided E-visual DLT into the right bronchus might offer more advantageous one-lung ventilation...

BACKGROUND AND OBJECTIVE: The management of large mediastinal tumors requires a complex multidisciplinary approach, particularly in the perioperative setting due to increased risk of hemodynamic compromise. The utilization of extracorporeal membrane oxygenation (ECMO) provides a useful adjunct in the surgical management for biopsy and resection of these mediastinal masses. The objective of this article is to review indications and implementation of ECMO in the surgical management of mediastinal disease...

Mediastinal venolymphatic malformations (VLM) are rare tumours, with very few reported cases in the literature. Arising often from the anterior mediastinum, VLM manifests symptoms based on invaded surrounding structures. Masses from the anterior and superior mediastinum pose an anaesthetic challenge for airway and hemodynamic management. A 7-month-old male child presented with a progressively growing mass over the left anterior chest wall for one month, about 4x4 cm, with diffuse margins and now expanded to involve the root of the neck and into the axilla...

PURPOSE: Anatomically correct patient-specific models made from medical imaging can be printed on a three-dimensional (3D) printer or turned into a virtual reality (VR) program. Until recently, use in anesthesia has been limited. In 2019, the anesthesia department at Tel Aviv Medical Center launched a 3D program with the aim of using 3D modelling to assist in preoperative anesthesia planning. METHODS: A retrospective review of all relevant patients between July 2019 and June 2021 referred for preoperative airway planning with 3D modelling...

Brachial plexus tumors are rare and pose challenges for neurosurgeons due to their anatomical complexity. Retrosternal extension of a tumor makes it more difficult for the surgeons as well as for the anesthesiologists to secure a definitive airway. A cardiopulmonary bypass would be lifesaving in the event of acute cardiorespiratory decompensation. Multidisciplinary collaboration and cooperation between the neurosurgeon, oncosurgeon, cardiothoracic surgeon, and anesthesiologist are imperative to ensure good patient outcomes...

Anesthesia management of patients with mediastinal mass compressing the central airway is considered challenging. It is widely believed that general anesthesia induction in patients with mediastinal mass is associated with airway collapse, difficulty in ventilation and hemodynamic compromise. Additionally, several case reports and case series described patients demise after induction of general anesthesia. This has led to the strong recommendations to use inhalation induction, avoid the use of muscle relaxant and maintenance of spontaneous ventilation...

Mediastinal mass syndrome (MMS) is a life-threatening complication of anesthesia for which prevention and treatment are a complication-prone interdisciplinary task. Clinical symptoms vary from asymptomatic patients up to life-threatening cardiorespiratory impairments, depending on the extent and size of a mediastinal tumor as well as the involvement of corresponding anatomical structures. Especially in the context of sedation or general anesthesia, there is a considerable risk of acute cardiopulmonary or respiratory decompensation related to tumor-induced compression of central blood vessels or even the large airways, which may result in severe complications, including death...

BACKGROUND: Giant mediastinal mature teratomas may cause airway obstruction or decreased venous return due to the mass effect. Preoperative stabilization of the respiratory and circulatory systems is important for perioperative management to safely perform surgery, including general anesthesia. However, to the best of our knowledge, there are only a few reports regarding the preoperative computed tomography (CT)-guided drainage of mediastinal tumors. CASE PRESENTATION: A 30-year-old woman was admitted to the emergency room with sudden dyspnea...

A 30-year-old woman who presented loss of consciousness was diagnosed as having large anterior mediastinal tumor. Computed tomography (CT) showed a 17.0×13.0×7.3 cm cystic mass with internal calcification in the anterior mediastinum that was markedly compressing the heart, great vessels, trachea and bronchi. A mature cystic teratoma was suspected, and the mediastinal tumor was resected through a median sternotomy. At the induction of anesthesia to prevent the development of the respiratory and circulatory collapse, the patient was consciously intubated under the right lateral decubitus position while preparing for percutaneous cardiopulmonary support by cardiac surgeons, and the surgery was safely performed...

Mediastinal tumors are a remarkably diverse category. They include malignant and benign forms with different rates of disease progression and tissue invasion. Anesthesiologists may encounter significant difficulties in managing patients with giant mediastinal tumors due to the non-negligible occurrence of severe cardiorespiratory collapse. Respiratory complications ensue from the compression of the airways induced by the mediastinal mass: the compressive effects may be exacerbated by positioning or anesthesia induction...

Patients with Marfan syndrome present anatomic variations that may increase the risk of a difficult airway. Moreover, they can present large aortic aneurysms, which may cause extrinsic airway compression. Therefore, difficult ventilation during general anesthesia poses a challenge in that the anesthesiologist has to promptly make a crucial differential diagnosis. Multidisciplinary preoperative assessment and planning of the airway and ventilation management are of utmost importance in such uncommon and highly complex clinical cases...

Mediastinal masses can compress the respiratory or cardiovascular system, especially when anteriorly located. Obtaining histological material for diagnosis poses a challenge due to the major risk of cardiorespiratory collapse following anesthetic procedure. Our case shows the utility of rescue with venovenous extracorporeal membrane oxygenation (VV-ECMO) after occurrence of such an event and demonstrates the feasibility of administering chemotherapy during VV-ECMO. A 4-year-old boy was referred to the pediatric oncology clinic of our hospital after a large mediastinal mass was observed on chest radiography ordered due to persistent cough...

BACKGROUND: Lipofibroadenoma is an extremely rare thymic tumor, and the anterior mediastinum is the most common site. CASE SUMMARY: A 21-year-old male was admitted with fever without obvious cause for 2 months. After admission, the patient's highest temperature was 38.3°C, accompanied by diarrhea. Physical examination showed coarse breath sounds in both lungs. Chest enhanced computed tomography (CT) showed a mass of mixed density shadow on the left side of the anterior mediastinum with a size of approximately 9...

OBJECTIVES: To summarize the anesthetic management of patients undergoing mediastinal mass operation. METHODS: Electronic databases were searched to identify all case reports of patients undergoing mediastinal mass operation. Information such as clinical characteristics, perioperative management and patients' outcomes were abstracted and analyzed. RESULTS: Seventy-seven case reports with 85 patients aging from 34 days to 81 years were included...

<b/> A case of mediastinal bronchial cyst misdiagnosed as schwannoma is reported. The patient had no chest pain, dyspnea, cough, sputum and hemoptysis in the past. Chest enhanced CT showed mediastinal mass with clear boundary. The larger cross-section was about 3.9 cm × 3.4 cm, and there was no obvious enhancement. The primary diagnosis was considered as schwannoma, tracheal cyst or esophagus cyst. The mediastinal tumor was resected via cervical approach under general anesthesia. During the operation, it was found that the mass was located in the middle and upper mediastinum, with diameter of about 4 cm and a smooth surface, containing gelatinous cystic fluid and adhered to the esophagus and trachea...
