Structural component of the 10-12 nm diameter microfibrils of the extracellular matrix, which conveys both structural and regulatory properties to load-bearing connective tissues (PubMed:15062093, PubMed:1860873). Fibrillin-1-containing microfibrils provide long-term force bearing structural support (PubMed:27026396). In tissues such as the lung, blood vessels and skin, microfibrils form the periphery of the elastic fiber, acting as a scaffold for the deposition of elastin (PubMed:27026396). In

Marfan syndrome
A hereditary disorder of connective tissue that affects the skeletal, ocular, and cardiovascular systems. A wide variety of skeletal abnormalities occurs with Marfan syndrome, including scoliosis, chest wall deformity, tall stature, abnormal joint mobility. Ectopia lentis occurs in most of the patients and is almost always bilateral. The leading cause of premature death is progressive dilation of the aortic root and ascending aorta, causing aortic incompetence and dissection. Neonatal Marfan syndrome is the most severe form resulting in death from cardiorespiratory failure in the first few years of life.

Perioperative Anesthetic Management of Giant Mediastinal Tumors: Current Advances and Evidence-Based Strategies.
Perioperative anesthetic management of giant mediastinal tumors presents significant challenges in cardiothoracic anesthesia due to the risk of mediastinal mass syndrome. This comprehensive review synthesizes recent evidence on risk stratification, evolving anesthetic techniques, and innovative support technologies. Contemporary evidence challenges traditional dogma, demonstrating that positive pressure ventilation and neuromuscular blockade can be safely applied under appropriate monitoring in selected patients. Risk stratification incorporating tumor size (≥0.5 ratio), airway compression (>50%), and hemodynamic parameters enables individualized management approaches. Extracorporeal membrane oxygenation has evolved from rescue therapy to prophylactic support, with clear guidelines for deployment. Tumor-specific protocols address unique challenges, including tumor lysis syndrome in lymphomas, myasthenic crisis in thymomas, and coagulopathy in germ cell tumors. The integration of advanced monitoring, prophylactic extracorporeal membrane oxygenation strategies, and evidence-based protocols provides a framework for safe management while expanding surgical feasibility for these complex cases.
Safe Resection of a Giant Mediastinal Liposarcoma with Severe Cardiac Compression.
Dedifferentiated liposarcomas of the mediastinum are exceedingly rare, and surgical resection is the primary treatment of choice. Mediastinal mass syndrome (MMS) is an oncological emergency characterized by compression or invasion of the heart, great vessels, or trachea by a large mediastinal tumor, particularly during the induction of anesthesia. We report a case of a giant dedifferentiated liposarcoma in the anterior mediastinum, surgically resected due to severe cardiac compression and presenting as an oncological emergency. A 70-year-old male presented with palpitations, generalized fatigue, and chest tightness. Chest radiography revealed an enlarged mediastinal shadow, prompting referral to our hospital. CT revealed a rapidly growing, giant anterior mediastinal tumor measuring 22 × 14.5 × 8.5 cm. The mass caused significant cardiac compression and extended into the pleural cavity. A CT-guided percutaneous biopsy confirmed a dedifferentiated liposarcoma. Given the patient's presentation of tachycardia and relatively low blood pressure secondary to the large tumor, a semi-urgent surgical resection was planned. Surgical resection was performed with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) on standby, anticipating potential hemodynamic decompensation during the induction of general anesthesia and surgery. Remarkably, the patient's hemodynamics remained stable throughout the induction of general anesthesia, without requiring VA-ECMO support. A clamshell incision allowed for complete tumor resection, including a portion of the pericardium. Postoperatively, the patient recovered uneventfully, except for transient paroxysmal atrial fibrillation and heart failure. The final pathological diagnosis confirmed dedifferentiated liposarcoma, with tumor cells affecting the pericardial and anterior chest wall surgical margins. The patient received postoperative radiation therapy and adjuvant chemotherapy and has remained free of recurrence for 1 year after surgery. We successfully performed semi-urgent surgery in a patient with a rapidly growing, giant anterior mediastinal mass causing severe cardiac compression, with VA-ECMO on standby. As MMS constitutes an oncologic emergency, careful assessment of subjective symptoms and imaging findings is required to determine the need for preparing or initiating extracorporeal life support.
Complete Resection of a Giant Mediastinal Liposarcoma Extending Into Both Pleural Cavities via Median Sternotomy: A Case Report.
Surgical resection is the primary treatment for giant mediastinal liposarcoma. However, aggressive R0 resection involving major nerves can lead to fatal functional loss. Clinicians must balance oncological radicality with functional preservation, as early diagnosis remains the most critical factor for avoiding highly morbid, extensive surgeries.
Cognitive aids in thoracic emergencies.
This review summarizes anesthetic challenges in up-to-date developments of cognitive aids in thoracic anesthesia emergencies. Recent advancements demonstrate a progression toward structured, algorithm-driven approaches that mitigate cognitive overload, enhance team coordination, and support clinical decision-making during rare, high-stakes events such as massive hemoptysis, tracheobronchial obstruction, mediastinal mass syndrome, or pericardial tamponade. Evidence highlights that cognitive aids - ranging from checklists and flowcharts to simulation-based mnemonics - improve recall, technical performance, and interdisciplinary communication, thereby reducing errors and omissions of essential steps in the acute setting, although they cannot substitute clinical judgement. While several conditions, including massive hemoptysis and mediastinal masses, are supported by structured frameworks, others such as bronchopleural fistula, aortoesophageal fistula, or diaphragmatic rupture still lack standardized tools and yet depend largely on institutional case-based experience and expert opinion. Well-designed cognitive aids facilitate critical priorities such as airway protection, bleeding control, and hemodynamic stabilization, and guide complex multidisciplinary interventions like bronchial artery embolization or thoracic endovascular aortic repair. Their successful use requires appropriate design and thoughtful integration into local practice, simulation training, and crisis resource management. Future efforts should focus on systematic development and validation of specialty-specific tools to optimize patient outcomes and strengthen resilience in thoracic anesthesia crisis management.
