Effectiveness of Fluoroscopy-Guided Percutaneous Vertebral Biopsy[*]Artikel in mehreren Sprachen: português | English
Objective To define the effectiveness of fluoroscopy-guided percutaneous vertebral biopsy.
Methods Prospective study of patients with vertebral destruction syndrome at one institution. Percutaneous transpedicular vertebral biopsies guided by fluoroscopy were performed, and bony tissue and intervertebral disc tissue were extracted; histopathology and microbiology studies were also performed. Age, sex, vertebral segment, neurologic status, and biopsy and culture results were analyzed.
Results The average age of the patients was 53.8 years (range: 2 to 83 years), and the main spine segment was the lumbar segment in 62% of the cases. According to the impairment scale of the American Spinal Injury Association (ASIA), preoperatively, 49% of the patients were classified as Asia E, and 100% had pain. Definitive etiology was identified in 83% of the sample. The etiology was grouped into three categories: infectious, neoplasia, and degenerative (osteoporotic). The infectious group was composed of 36% of the patients, in whom Staphylococcus aureus was the most common agent identified; in 34.9% the sample, the etiology was neoplastic, most commonly multiple myeloma and metastatic disease due to prostate cancer; 21.7% of the patients had osteoporosis. The average surgical time was of 47.5 minutes, the average blood loss was of 10 mL. No complications were reported.
Conclusion Transpedicular percutaneous biopsy guided by fluoroscopy had an effectiveness of 83% for the etiological diagnosis of vertebral destruction syndrome in the present series. It should be considered a useful minimally-invasive procedure, which is easy, economical, and reproducible, with low risk of short- and long-term complications.
