{Abstract}: BACKGROUND: Spinal arteriovenous shunts and spinal dysraphism both have a different underlying cause, disease spectrum and developmental process; hence, these entities rarely coexist in a patient. Here, we reported four cases of coexistence of adult-onset spinal arteriovenous shunt and spinal dysraphism in the same patient along with their therapeutic embolisation. Additionally, we conducted an extensive literature review to explore the potential theories and explanations for this coexistence.
METHODS: We retrospectively searched our imaging database from January 2015 to December 2023 to identify instances of spinal arteriovenous shunts occurring in patients with spinal dysraphism or neural tube defect disorders. MRI and angiographic imaging, clinical presentation, treatment and follow-up were analysed.
RESULTS: Four patients with arteriovenous fistula/shunt and spinal dysraphism were included in the study. The mean age of presentation was 35.5 years. The most common symptoms were sensory disturbance and motor weakness. Arteriovenous fistula or shunt was located at the lumber region in one patient and at the sacral region in three cases. Two patients have a prior history of surgery in first decade. Two patients were treated with glue embolisation. The internal iliac artery was a common feeder in all cases.
CONCLUSIONS: The rare coexistence of neural tube defects with spinal vascular abnormalities should be considered when assessing a middle-aged patient with neural tube defect and myelopathy. Correct diagnosis can help in treatment planning and thereby improve prognosis.
