Introduction: The occurrence of symptomatic spinal epidural hematoma after spine surgery is a rare, but serious major complication whose incidence usually requires urgent surgical intervention. Obesity is currently considered to be one of the most common metabolic diseases.
Methods: Prospective analysis of patients who underwent surgical treatment of degenerative lumbar spine disease from January 2016 to February 2018 with one-year follow-up. All patients underwent decompression of spinal cord and nerve roots. This study was conducted to determine an association between the incidence of spinal epidural hematoma (SEDH) requiring surgical treatment and obesity/body mass index (BMI).
Results: In our study, data from 371 patients were assessed. SEDH requiring surgical intervention occurred totally in seven patients (1.89 %). An average BMI in patients with presence of SEDH was 30.67 kg/m2. Our work showed a statistically significant difference between BMI in patients with SEDH compared to patients without SEDH (p = 0.0044). This study also showed a significant difference in incidence of symptomatic SEDH in obese patients compared to non-obese patients (p=0.0158).
Conclusion: In our study, we found out that obesity is a significant risk factor for the incidence of postoperative SEDH after degenerative lumbar spine surgery (Tab. 1, Fig. 2, Ref. 18).
