Abstract
This report deals with a case of spinal dural arterio-venous malformation associated with pain in the back and lower extremities.
A 53-year-old male patient presented with intermittent claudication and dysuria as well as pain in the back and lower extremities. After detailed examinations, he was diagnosed as having spinal dural arterio-venous malformation fed mostly through Th7-8 intercostal arteries. Embolization was performed successfully for the arterio-venous malformation, but the pain in the back and lower extremities persisted. For the pain relief, caudal block was repeated and carbamazepine as well as mianserin were administered. These treatments led to the successful relief of his pain.
Spinal dural arterio-venous malformation is a rare disease, but it is important to take this disease into consideration when a patient presents with severe pain in the back and lower extremities. This case also suggests that pain may persist after the successful embolization of the malformation.
