A 21-year-old male sustained a single gunshot wound with entry over the left scapula. At the scene, the emergency medical response personnel found him on the ground alert, unable to move his legs, and noting pain all over his body. He was hemodynamically stable in the field. Ground ambulance immobilized the neck with a cervical collar and brought him to a local level 1 trauma center. At arrival to the trauma bay, he had a Glasgow coma scale score of 15. He was primarily complaining of bilateral hand numbness. On further examination, he had no motor or sensory function present in the lower extremities. In the upper extremities, sensation was present but diminished from T1 and above, with no sensation below T1. Motor function in the upper extremities was graded 3 (based on ASIA impairment scale) in all the key muscles on the right and only grade 2 on the left in the deltoid and biceps muscles with no motor further distal. Next, he was taken to the computed tomography (CT) suite for imaging of the head, neck, and thorax. Imaging, from the CT scan, revealed bullet tract through the posterior lateral left upper hemithorax, left scapular body, left lung apex, and base of left neck with bullet fragments terminating in the C6 vertebral body. Initial studies showed no acute intracranial abnormalities; however, there were fractures of the left C5 and C7 transverse foramina and processes and left C6 vertebral body and lamina fractures with bony and bullet fragments in the left aspect of the spinal canal at the C6 level (). As a result, there was a dense left epidural hematoma within the spinal canal at C2 through C7 levels. At the time, CT neck angiogram showed that the left extracranial vertebral artery was occluded, beyond 1 cm from its origin. Subsequently, the patient underwent angiography to further assess the cerebral vascular supply. On the angiogram, occlusion of the proximal portion of the left vertebral artery was noted with reconstitution in the distal portion of the artery near the occipitocervical junction (). No contrast extravasation from the left vertebral artery was noted. Patency was noted in the right vertebral artery and bilateral common, internal, and external carotid arteries. Vascular surgery specialists, after conducting and reviewing the angiogram, determined that no further intervention was required as the right vertebral artery along with bilateral internal carotid arteries was patent.\nFollowing the imaging studies and angiogram, the patient was admitted to the surgical intensive care unit (SICU) for continuous neurologic and hemodynamic control and observation. On the next hospital day, the patient was optimized by the vascular surgery team and the surgical intensive care unit trauma team and was deemed stable to proceed forward with surgical intervention of the spine. Given the spinal cord injury and preparation for spinal surgery, anticoagulation was not started prior to reporting to the operating room. The goals of the surgery were to decompress the cervical spinal cord and to provide stability to the spinal column.\nThe patient received a successful awake fiber-optic intubation with protection of the cervical spine and then general anesthesia was induced. Via a standard left sided Smith-Robinson approach, anterior cervical corpectomy of C6 and anterior cervical decompression were performed within C5–C7. Bony and bullet fragments were removed from within the canal and following decompression, and while avoiding excessive distraction, the anterior column was reconstructed using an appropriately sized interbody cage device packed with autologous bone graft. Anterior cervical plate and screws were used to provide stability to the cage-graft construct and maintain the proper cervical alignment (). Following the procedure, the patient remained intubated for airway edema concerns. The sedation was weaned after transporting the patient to the SICU from the operative suite; however, he remained unarousable. Given the neurologic change in the patient status, an emergent head CT scan was conducted and showed an acute basilar infarct.\nHead and neck CT angiogram were subsequently performed and showed new basilar artery segmental occlusion consistent with migration of a thrombus from the distal left vertebral artery. Both neurology and neurosurgery teams recommended hyperosmolar treatment, as the patient was not considered a good candidate for revascularization. Twelve hours later, repeat head CT scan showed progressive hydrocephalus and brainstem and cerebellar infarcts with impending herniation (). The patient was subsequently diagnosed with brain death and, with consent from his family, care was withdrawn.
Eleven-year-old boy presented to a hospital after he had been shot with an arrow by his younger brother while they were playing with a bow. The arrow stuck in a posterior surface of his neck (nuchal region) about the level of C5 vertebra and the arrow shaft was immediately removed by a brother. The parents brought their son to a local hospital where initial neck X-ray examination was performed. The only injury exposed to a physician’s view was a small, 1 cm long skin cut with no pathological secretion. The X-ray revealed a 35 mm long, cone-shaped metal arrowhead residing between C4 and C5 vertebra and protruding into the vertebral canal (Fig. ). Nevertheless, the boy did not present any neurological deficit nor paraesthesia. He was equipped with a professional neck support, placed on a rescue board, and transmitted to Department of Pediatric Neurosurgery. On admission, he underwent head and neck CT examination, that showed the arrowhead stuck between arches of C4 and C5 vertebrae, protruding inside the vertebral canal and passing through the cervical spinal cord penetrating to 2/3 of its P-A dimension (Fig. ). CT scans did not reveal any bone injury, intraspinal bleeding, nor edema. During neurological examination, the boy still did not demonstrate any neurological nor meningeal symptoms, numbness, neither sensation disorders. An initial treatment with methyl-prednisolone infusion according to National Acute Spinal Cord Injury Studies (NASCIS) protocol was implemented, and the patient was transported to an operating theater with a total of rescue supports. The boy was placed horizontally in prone position, with the nuchal region exposed. From the straight vertical skin incision, the C4-C5 area was achieved and the upper back muscles were carefully dissected and put aside. The exposed metal arrowhead was gently removed and no negative general patient reaction was observed. The arrowhead was cone-shaped and hollow, had 35 mm of length and 6 mm of diameter at its base (Fig. ). Subsequently, a bilateral C4–C5 hemilaminectomy was performed in order to verify the injury of spinal cord and dura. In the traumatized area, no fresh bleeding was observed but the leakage of transparent cerebrospinal fluid. The dura was closed with continuous suture, and precise hemostasis of the operative field was performed. Finally, all layers were closed down. The patient was equipped with a neck support and spent next 2 weeks at the Department of Pediatric Neurosurgery. The treatment included continuous intravenous antibioticotherapy (ceftriaxone, amicacinum, and metronidazole) and lying in bed during first week of hospital stay followed by a gradual rehabilitation in the second. Postoperative neurological statement did not deteriorate; the boy did not suffer from paraesthesia nor other deficits. Postoperative wound healed properly. Control neck MRI, performed soon after, revealed no fresh bleeding nor edema in operated region. After 2 weeks, the treatment was terminated and the boy was discharged from the hospital in a state of complete health. Follow-up MRI examination after 6 months from surgery revealed no pathological collection nor postoperative spinal stenosis in operated region. The presence of focal (Ø up to 10 mm) hyperintensive region in the spinal cord did not influence his neurological statement (Fig. ).
