RESUMO
OBJECTIVE: Basilar impression (BI) is a rare yet debilitating abnormality of the craniovertebral junction, known to cause life-threatening medullary brainstem compression. Our study analyzes surgical approaches for BI and related outcomes. METHODS: A systematic review was conducted using PubMed, Google Scholar, and Web of Science electronic databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to critically assess primary articles examining BI. RESULTS: We analyzed 87 patients from 65 articles, mostly female (55.17%) with a mean age of 46.31 ± 17.94 years, commonly presenting with motor (59.77%) and sensory deficits (55.17%). Commonly employed procedures included posterior occipitocervical fusion (24.14%), anterior decompression (20.69%), and combined anterior decompression with posterior fusion (21.84%). Patients who underwent anterior approaches were found to be older (55.38 ± 17.67 vs. 45.49 ± 18.78 years, P < 0.05) and had a longer duration from symptom onset to surgery (57.39 ± 64.33 vs. 26.02 ± 29.60 months, P < 0.05) compared to posterior approaches. Our analysis revealed a significant association between a longer duration from symptom onset to surgery and an increased likelihood of undergoing odontoidectomy and decompression (odds ratio: 1.02, 95% confidence interval: 1.00-1.03, P < 0.05). Furthermore, after adjusting for all other covariates, a history of rheumatoid arthritis and the use of a posterior approach were significantly associated with an elevated risk of postoperative complications (P < 0.05). CONCLUSIONS: The treatment approach to complex craniovertebral junction disease should be tailored to the surgeon's experience and the nature of the compressive pathology.

OBJECTIVE: Anterior cervical spine operations are commonly performed on cervical spine pathologies and to a large extent are safe and successful. However, these surgical procedures expose the vertebral artery, posing a risk of harm to it. METHODS: A systematic review was conducted using PubMed, Google Scholar, and Web of Science electronic databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to critically assess primary articles discussing treatment strategies "vertebral artery injury" AND "anterior cervical spine" and develop a management strategy based on our experience and meta-analysis of the literature. In addition, we present an illustrative case of iatrogenic vertebral artery injury presenting with 6 to 7 months' history of progressive dysphagia was transferred to our care from an outside institution. RESULTS: Included and analyzed were 43 articles that detailed 75 cases involving vertebral artery injury (VAI) in anterior cervical spine operations. Preoperatively, frequent clinical findings reported were sensory deficit (26 patients [63.41%]), motor deficit (20 patients [48.78%]), and pain (17 patients [41.46%]). In total, 32 patients (50.00%) endured injury of their left VA, and 30 patients had a right VAI. The 2 common causes of VAI were drilling (24 patients [40.00%]) and instrumentation (8 patients [13.33%]). CONCLUSIONS: Altogether, our review recommends repair or tamponade packing with a hemostatic agent for primary management. Should tamponade packing with a hemostatic agent be used for primary management, secondary management should entail either repair, stenting occlusion, embolization, anticoagulants, or ligation. Further examination of this treatment strategy based on a larger cohort is necessary.
