Expansile manubriotomy for ventral cervicothoracic junction disease

摘要

Cervicothoracic junction can be approached anteriorly, anterolaterally, posterolaterally, and posteriorly. The anterior approaches in this region best address the ventral vertebral body disease but may cause significant morbidity. Twelve patients with their disease process located ventral to the spinal cord in the cervicothoracic junction underwent expansile manubriotomy and corpectomy. Eleven patients underwent fusion. One patient underwent an oblique corpectomy. All patients had their disease process from T1 to T3 vertebral levels. After dissection, the manubrium was cut open in the midline until the sternal notch. Further manubrial cut was extended laterally to just below the second rib. A self-retaining retractor was placed and opened. This gave an additional exposure of 10 cm from the midline towards the right side. It also opened the thoracic inlet. The superior mediastinum was dissected. Brachiocephalic vessels were looped down and a plane was made between the carotid artery laterally, and the trachea and esophagus medially. The prevertebral fascia was reached and opened to access the vertebral body. The procedure could be carried out successfully in all the patients. A patient with uncontrolled diabetes mellitus and end-stage renal disease with pyogenic epidural abscess succumbed to her illness after 3 weeks. Expansile manubriotomy is technically feasible, less invasive, and least morbid of all the anterior approaches for accessing the anteriorly located disease process above the T4 vertebral level.
