Tips and Complications of Two-step Open Procedure for Ethanol Sclerosis Therapy for a Venous Hemangioma of the Thoracic Spine: A Case Report.

This case highlights the following: First, the two-step procedure of open biopsy followed by ethanol injection using the open approach allowed accurate diagnosis and effective treatment. Second, additional injection of a water-soluble contrast medium to confirm sclerosis after ethanol injection can cause paralysis. Third, a mixture of ethanol and a lipid-soluble contrast medium effective improves visibility to identify expansions. These experiences will be useful for following ethanol sclerosis therapy for a venous hemangioma of the thoracic spine.
