Microsurgery of spinal cord Intramedullary cavernous hemangioma

Objective To investigate the microsurgical effect of spinal cord Intramedullary cavernous hemangioma. Methods The clinical data of 23 patients with spinal cord Intramedullary cavernous hemangioma from January, 2003 to March, 2017 were analyzed retrospectively. McCormick clinical neurological function classification method and MRI examination were used to analyze the changes of neurological function and imaging changes before- and-after operation. MRI and assess nerve function were reviewed 6-12 months after discharge. Results Twenty-two cases were totally resected, and subtotal excised in 1 case. The symptoms improved and even disappeared completely in 17 cases. There was no obvious improvement in 4 cases, 2 cases were worse and no death cases. Twenty-one cases were followed-up. The follow-up time was 3 months-9 years, and no tumor recurrence was found. Among the 14 cases of clinical neurological function I-II, 10 cases recovered rapidly and most of the symptoms improved or even disappeared. Three cases had no obvious change. The other 1 case aggravated symptoms; Six cases of III-IV patients in 7 cases of postoperative recovery, and 1 case of no change. According to preoperative neurological function grade I-II and III-IV, the treatment effect of patients was compared, the difference was significant (χ2=5.25, P<0.05). Conclusion Microsurgical resection of spinal cord Intramedullary cavernous hemangioma is safe and effective. The preoperative nerve function, the relationship between the tumor and the spinal cord, and the surgical skill and the degree of resection are the important factors that affect the prognosis.
