Spontaneous non-traumatic mediastinal hematoma associated with oral anticoagulant therapy: A case report and literature review

چکیده
INTRODUCTION Mediastinal hematoma is usually caused by thoracic trauma or a ruptured aortic aneurysm. Spontaneous non-traumatic mediastinal hematomas are rare but potentially life-threatening conditions that can occur in patients taking anticoagulants. PRESENTATION OF CASE We report a case of 72-year-old man with a massive mediastinal hematoma associated with anticoagulant therapy. He had complained of acute chest discomfort and subsequent tarry diarrhea. Because he had been taking warfarin for paroxysmal atrial fibrillation, an upper gastrointestinal hemorrhage was initially suspected, but no bleeding was detected by upper endoscopy. A computed tomography scan revealed a massive posterior mediastinal hematoma and markedly compressed surrounding structures. The compression of the left atrium caused a congested lung and exacerbated respiratory and hemodynamic status despite conservative therapy. Therefore, we surgically removed the hematoma. Immediately after removal, the respiratory and hemodynamic conditions improved, and the postoperative course was uneventful. DISCUSSION Spontaneous mediastinal hematoma is rare but can occur in patients who are administered anticoagulants regardless of the therapeutic level of anticoagulation. Although conservative therapy is commonly effective, active surgical intervention should be considered for cases in which the hematoma is symptomatic or conservative therapy is ineffective. CONCLUSION To facilitate prompt and proper management, clinicians should be aware of this condition as a potential complication of anticoagulant therapy.

An Unusual Case of a Large Hematorrachis Associated with Multi-Level Osteoporotic Vertebral Compression Fractures; a Case Report
Spinal epidural haemorrhage may present as back pain associated with radicular symptoms and can be a catastrophic clinical scenario with progression to paraplegia or even sudden death. Being a rare entity, it needs a high index ofclinical suspicion to diagnose it. Fractures have been documented as a cause of hematorrachis but such hematomas only extend to one or two vertebral segments. Large ep...

Simultaneous intracranial and spinal subdural hematomas are extremely rare. In most cases, they are attributed to major or minor trauma and iatrogenic causes, such as those resulting from spinal puncture. To the best of the authors' knowledge, there has been only two reports of spontaneous concomitant intracranial and spinal subdural hematomas in a patient receiving anticoagulant therapy who ha...

Spontaneous hemomediastinum is a rare event, occurring in association with bleeding disorders, intratumoral bleeding, or following an abrupt increase in intrathoracic pressure. We report the case of a patient with systemic lupus erythematosus, nephrotic syndrome, and renal failure, in whom mediastinal lipomatosis (ML) developed following increased corticosteroid therapy. Anticoagulant therapy l...
