Overview
Rupture of syphilitic cerebral aneurysms is a rare but severe complication of neurosyphilis, leading to significant morbidity and mortality due to hemorrhagic stroke and subsequent multi-organ dysfunction 1.Diagnosis
Clinical Presentation: Headache, altered mental status, focal neurological deficits 1.
Imaging: CT or MRI angiography to identify aneurysm and hemorrhage 1.
Laboratory Tests: Non-treponemal tests (e.g., VDRL, RPR) and treponemal tests (e.g., FTA-ABS, TPHA) to confirm syphilis 1.Management
Antibiotic Therapy: Penicillin G (e.g., intravenous benzylpenicillin 18-24 million units daily) for neurosyphilis 1.
Surgical Intervention: Endovascular or surgical repair of the aneurysm may be considered in selected cases, though high risk due to multi-organ dysfunction 1.
Supportive Care: Intensive care management including hemodynamic stabilization, monitoring for multi-organ dysfunction 1.Special Populations
Comorbidities: Cardiovascular diseases significantly influence perioperative outcomes; careful risk stratification is essential 1.
No specific data: Limited information on pregnancy, pediatrics, or elderly populations regarding syphilitic cerebral aneurysm rupture 1.Key Recommendations
Initiate high-dose intravenous penicillin therapy promptly for confirmed neurosyphilis to address the underlying infection (Evidence: Strong 1).
Perform thorough preoperative risk assessment, particularly focusing on cardiovascular status and organ function, to predict outcomes (Evidence: Moderate 1).
Consider endovascular or surgical repair cautiously, given the high risk of multi-organ dysfunction post-rupture (Evidence: Expert opinion 1).References
