Subdural Empyema | Epidemiology and Pathophysiology

Subdural empyema is the cornerstone of this sqadia.com medical video lecture. Starting with epidemiology and pathophysiology of subdural empyema, clinical presentation and diagnosis also come under debate. Subsequently, treatment and prognosis are pursued along with intracranial epidural abscess. Conclusively, suppurative thrombophlebitis is considered. ▬ 📃 Epidemiology and Pathophysiology Subdural empyema (SDE) is a collection of pus between dura and arachnoid membranes. It is a rare disorder and epidemiologically accounts for 15-25%. The etiology of subdural empyema includes aerobic and anaerobic streptococci, staphylococci, and Enterobacteriaceae. Pathophysiology indicates it can be due to retrograde spread of infection, contiguous spread of infection, and direct introduction of bacteria. ▬ 📜 Clinical Presentation and Diagnosis Fever, progressively worsening headache, seizures, and nuchal rigidity are the clinical presentations. Seizures begin as partial motor seizures. MRI is indicated for diagnosis. Moreover, the administration of gadolinium greatly improves diagnosis. CT Scan shows a crescent-shaped hypodense lesion. Likewise, information about differential diagnosis is also delivered. ▬ 📃 Treatment and Prognosis Emergent neurosurgical evacuation of the empyema and empirical antimicrobial therapy are the treatment approaches. Moreover, combination therapy is also used. For treatment of hospital-acquired SDE, coverage with carbapenem and vancomycin is advised. Lastly, the prognosis is discussed. Long-term neurologic sequelae occur in 50% of cases. ▬ 📜 Intracranial Epidural Abscess A suppurative infection occurring in the potential space between the inner skull table and the dura is referred to as an intracranial epidural abscess. Etiology and pathophysiology are deliberated in succession. Diagnosis is considered when fever and headache follow recent head trauma. Alongside, light is shed on treatment and prognosis. ▬ 📃 Suppurative Thrombophlebitis A septic venous thrombosis of cortical veins and sinuses is known as suppurative thrombophlebitis. After that, Dr. Saima Mushtaq talks about anatomy and pathophysiology. The infection spreads from mastoid air cells to the transverse sinus. Clinical manifestations include weakness of the lower extremities. Clinical manifestations of septic cavernous sinus thrombosis and transverse sinus thrombosis are also enlightened. ▬ 🎬 5500+ sqadia.com Medical Videos ▬▬▬▬▬▬▬▬▬▬ 👩🏻‍⚕️ Accessible Medical Student Education 24/7/365 💡 Simplifying Medical Learning 💪 Study Hard, Dream Big, Achieve More
