| Popis: | Objective. To analyze the results of treatment of disseminated (polysegmental and multilevel) forms of hematogenous vertebral osteomyelitis (HVO) as compared with those of monosegmental and monovertebral lesions.Material and Methods. A retrospective analysis of a monocenter cohort of 266 patients with hematogenous osteomyelitis of the spine for 2006 to 2019 was carried out. Patients were divided into two groups: Group A (polysegmental and multilevel lesions) included 33 (12.4 %) patients and Group B (monosegmental and monovertebral lesions) – 233 (87.6 %) patients. The main examination methods were: clinical, radiological (standardized roentgenography, CT), MRI, microbiological, histological and statistical ones.Results. Comparison revealed that involvement of the cervical (p < 0.001) and thoracic (p = 0.014) spine was more typical for polysegmental and multilevel lesions. There was a tendency to the predominance of type A lesions according to the Pola classification in patients with local forms (p = 0.078) and to the increase in type C lesions in polysegmental and multilevel processes (p = 0.035). The number of neurological complications was higher in polysegmental and multilevel lesions (p = 0.003). There were no significant differences in the treatment results, the number of relapses and mortality rate between the compared groups.Conclusion. Lesions of the cervical and thoracic spine and the presence of a neurological deterioration are typical for multilevel and polysegmental HVO. The formation of a multilevel lesion in different regions of the spine with a gap of 2–4 weeks or more requires a separate implementation of the diagnostic algorithm, defining of classification criteria and differentiated treatment tactics for each focus. |
