Abstract
STUDY DESIGN: Evaluation of the surgical effects of patients with intramedullary spinal cord cavernous angiomas (CAs). OBJECTIVES: To assess the sensory and motor deficits in the clinical symptoms of patients with intramedullary CAs after complete surgical resection. SETTING: Seoul National University Hospital, Korea. METHODS: The authors reviewed 14 patients with intramedullary spinal cord CAs who underwent surgical resection between 1995 and 2006. The average follow-up duration was 55.0+/-45.1 months. To analyze the changes in the patients' symptoms after surgery, the ASIA (American Spinal Injury Association) and JOA (Japanese Orthopedic Association) scoring systems were used at different time points: preoperative, postoperative and during the final follow-up period. RESULTS: The patients' mean ASIA score at follow-up was increased in comparison to the preoperative score (97.2+/-5.3 vs 95.2+/-7.6, P=0.201), but this difference was not significant. The mean JOA motor score at follow-up was slightly increased in comparison to the preoperative score (7.2+/-1.3 vs 6.8+/-1.3, P=0.107). There was a significant difference between the patients' preoperative and follow-up JOA sensory score (4.3+/-1.0 vs 4.9+/-0.9, P=0.007). The rates of complete resolution of motor and sensory deficits were 45.5% (5/11 patients) and 7.1% (1/14 patients), respectively. CONCLUSION: Although complete surgical resection could improve the clinical symptoms of intramedullary CAs, the sensory deficits usually remain in the long-term period after complete resection.
