Risk Factor Analysis and Surgical Outcomes of Acute Spontaneous Spinal Subdural Hematoma. An Institutional Experience of Four Cases and Literature Review

We are pleased to share our research published on PubMed, which examines spontaneous spinal subdural hematoma (SSSDH)—a rare but serious neurosurgical emergency. This study evaluates risk factors, neurologic outcomes, and surgical treatment effectiveness based on our institutional experience and a comprehensive literature review.

Study Overview

📊 Patients Analyzed: 112 cases (including 4 from our institution)
👥 Gender Ratio: 1.3:1 (female/male)
📅 Mean Age: 60.25 years

Key Findings

⚠ Risk Factors for Poor Surgical Outcomes:

• Cervical SSSDH (P = 0.029)
• Preoperative neurologic deficit (P < 0.001)
• Use of anticoagulation medication (P < 0.001)

🩺 Bladder Dysfunction as a Predictor of Worse Recovery:

• Patients with bladder dysfunction and paraparesis had poorer postoperative outcomes, making this an important new risk factor.

Clinical Implications & Recommendations

✅ SSSDH is more common in older patients (≥60 years) and those on anticoagulants
✅ Early diagnosis & surgical evacuation are crucial for better neurological recovery
✅ Bladder dysfunction should be recognized as a significant risk factor for poor prognosis
