DSA Analyzation and Embolization Treatment of Spinal Vascular Malformations

Purpose To evaluate the diagnosis value of spine angiography in treatment of spinal malformation. Methods Sixteen cases of spine vascular malformation were examined by selective spine angiography and treated by intravascular embolization. Results According to the location and shape, distribution of abnormal vessels, feeding arteries and draining veins displayed by DSA, the disease was divided into three types: 4 cases of spinal cord arteriovenous malformations; 4 cases of perispinal arteriovenous fistulas; 8 cases of spinal dural arteriovenous fistulas. Sixteen cases receiving embolization treatment, satisfied effects were in 13 cases and no changes in 2 cases. During follow up 2 months to 3 years, clinical symptoms were relieved in 13 cases. Conclusion Selective angiography is the only method for diagnosing spinal vascular malformation. DSA can show the location,feeding arteries and draining veins of spinal vascular malformation. Embolization treatment is a method with less invasiveness and fewer complications.
