Nevertheless, the clinical outcomes of surgical treatment remain incompletely characterized. Here, we evaluated the safety and clinical outcomes of 6 microsurgical decompressions for dorsal thoracic arachnoid bands in a single-center cohort.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Six patients underwent surgery for dorsal thoracicspinal arachnoid bands with\/without syringomyelia (2021\u20132025) at a single center. Demographic, diagnostic, and surgical reports and outcomes were assessed. Surgical decompressions utilized microsurgical techniques and intraoperative neurophysiological monitoring.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Six patients averaged 49.3 years of age, and four were female. T6 was the most involved thoracic level. Surgery included mostly hemilaminectomies addressing 6 arachnoid bands and 4 syrinxes. Postoperatively, 5 patients improved, while one remained unchanged. Only one postoperative adverse event occurred: pneumonia. Postoperative magnetic resonance studies documented complete arachnoid band\/syrinx resolution.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Microsurgical decompression of dorsal spinal arachnoid bands is both safe and effective.<\/jats:p>\n
