Objective: To analyze the clinical characteristics and treatment outcomes of spinal filum terminale vascular malformation. Methods: The clinical data of 6 patients with filum terminate vascular malformation diagnosed and treated from January 2008 to December. 2013 were analyzed retrospectively. The definition of filum terminale vascular malformation is anterior/posterior spinal artery feeding arteriovenous fistula or arteriovenous malformation and located below conus medullaris, and does not complicate with spinal vascular lesions in the other part. The Aminoff & Logue score and MRI of spinal cord function were performed at one year after microneurosurgery and/or endovascular embolization. Results: All patients were males. Their clinical presentations were the weakness of both lower extremities and sphincter disturbance. The mean course of disease was 17.1 ±5.2 months. The pathological type of the 6 patients were all arteriovenous fistulas. The feeding arteries included lumbar artery,internal iliac artery,and median sacral artery. Two of the 6 patients underwent Onyx glue embolization, 3 were treated with microneurosurgery,and 1 was treated with embolization in combination with microneurosurgery. They were all achieved anatomic cure. The Aminoff & Logue scores were improved after 1 year (3.8 ±1.9 scores before procedure,2.8 ± 2.0 scores after procedure), there was no significant difference (P > 0.05). The myodynamia scores were improved in 3 patients,2 did not change, 1 got worse. The urinary and bowel functions were improved in 2 patients, and 4 did not change. Conclusion: Filum terminale vascular malformation is a rare vascular malformation of spinal cord. Both embolization and surgical treatment can achieve anatomic cure. Although the spinal cord function can be only partially restored, but continuous deterioration can be prevented. Copyright 2014 by the Chinese Medical Doctor Association.
