Case Reports
Surgical management of cervical radiculopathy caused by redundant vertebral artery loop.
In this article, the authors describe the case of a 27-year-old female presenting with a 2-year history of neck pain and radiculopathy attributable to compression of the right C-7 nerve root by tortuosity of the vertebral artery at the level of the C6-7 cervical foramina. An anterolateral approach to the transverse foramen was used to perform a vascular decompression to decompress the nerve root. The procedure was uneventful, and the patient woke up with almost all of her symptoms resolved. The authors also include a literature review of techniques performed in this setting, showing that multiple surgical approaches can be used and should be tailored to the patient symptoms and lesion characteristics.

Cervical chordomas are rare lesions and usually bring about challenges in treatment planning because of their wide extension and complicated adjacent anatomy. There are few large published series at present focusing on cervical chordomas. The authors studied a consecutive series of 14 patients with primary cervical chordomas who underwent surgical treatment and were observed between 1989 and 2008. By reviewing the clinical patterns and follow-up data, they sought to investigate the clinical characters, tailor the appropriate surgical techniques, and establish prognosis factors for cervical chordomas. ⋯ Chordomas in the cervical spine are usually neoplasms that exhibit insidious growth and a wide extension by the time of diagnosis. Radical intralesional debulking surgery and postoperative radiotherapy have been effective treatment. A limited application of en bloc tumor resection and the highly likely intraoperative intralesional tumor seeding may partially explain the high local recurrence rate, whereas the chance of distant metastases, fortunately, is very low. Most recurrence were documented within 3 years. Some specific surgical techniques should be emphasized to minimize tumor seeding. Patients with upper cervical chordomas, younger adults, and elderly adults have worse prognosis. For patients with chordoma extending to both the anterior and posterior spinal columns, total spondylectomy combined with piecemeal excision is recommended for a better prognosis.
