Initial Experience with O-Arm Navigated Spinal Surgery - Report on Two Cases.

Image-guided spinal surgery is becoming increasingly popular because it allows surgeons to achieve minimal invasiveness and maximum precision in the performed procedures. We present our initial experience with two cases operated on using O-arm-based spinal navigation at the Clinic of Neurosurgery in St George University Hospital, Plovdiv, Bulgaria. In the first case, we performed removal of extradural spinal tumor of the sixth thoracic vertebra and O-arm-navigated pedicle screw fixation.

Surgical management of metastatic tumors of the cervical spine.

Objective: To present the results from the clinical presentation, the imaging diagnostics, surgery and postoperative status of 17 patients with cervical spine metastases, to analyse all data and make the respective conclusions and compare them with the available data in the literature.

Patients And Methods: The study analysed data obtained by patients with metastatic cervical tumours treated in St George University Hospital over a period of seven years. All patients underwent diagnostic imaging tests which included, separately or in combination, cervical x-rays, computed tomography scan and magnetic-resonance imaging.

Spontaneous cervical epidural hematoma. A case report.

Unlabelled: Spontaneous spinal epidural hematoma is a rare disorder. We present a case of a 55-year-old man who was awakened by severe pain in the neck and shoulders and inability to move his arms and legs. He was admitted to the clinic as an emergency.

Recurrence of epidermoid cyst in the third ventricle. Case report.

The authors present the case of a 34-year-old man. The patients was admitted for the second time in the clinic. A year before an epidermoid cyst of the third ventricle, obstructing the two foramen Monroe and causing acute hydrocephaly, was surgically removed.
