Abstract：Objective To explore the clinical application value of 4D-DSA in the diagnosis and treatment of spinal vascular diseases.Methods The clinical and imaging data of 13 patients with spinal vascular diseases admitted from March 2018 to March 2023 were retrospectively analyzed.Results 4D-DSA diagnosed 8 cases of spinal dural arteriovenous fistula,2 cases of perimedullary arteriovenous fistula,2 cases of spinal arteriovenous malformation,and 1 case of spinal epidural ar-teriovenous fistula.The 4D-DSA images clearly displayed the number of fistulas,feeding arteries,and draining veins,as well as the venous drainage direction.The structures of the feeding arteries,draining veins,and nidus within the malformation were also clearly demonstrated in the 2 patients with arteriovenous malformation.Eleven patients with arteriovenous fistula under-went endovascular embolization or surgical treatment guided by 4D-DSA,and their spinal cord function improved to varying degrees postoperatively.Two patients with arteriovenous malformation received conservative treatment with poor outcomes.Conclusion 4D-DSA can help clinicians more intuitively and accurately understand the intravascular architecture and hemody-namics of spinal vascular diseases,optimize treatment plans,and reduce complications.
