Abstract：Objective To explore the endovascular embolization approaches for dural arteriovenous fistulas(DAVF)and their therapeutic efficacies.Methods The clinical data of 47 patients with DAVF admitted to our hospital from January 2017 to January 2023 were retrospectively analyzed.Results Forty-two patients were treated via transarterial embolization(TAE),among which 40 patients achieved complete embolization immediately after the operation,1 had subtotal embolization,and 1 had partial embolization.Five patients were treated via transvenous embolization(TVE),and all achieved complete embolization immediately after the operation.At discharge,46 patients had a modified Ranking scale(mRS)score of 0～1,and 1 had a mRS score of 5.During the 6-month follow-up,1 patient died.The reexamination of DSA of the survival 46 patients revealed that 42 patients(91.3%)had complete embolization and 4(8.7%)had subtotal embolization[2 patients(4.9%)treated via the TAE recurred and 2(40.0%)via TVE recurred].A mRS score of 0 was achieved in 39 patients and a mRS score of 1 in 7.Conclusions Endovascular embolization is an effective method for tratment of patients with DAVF.The surgical approach should be selected based on the specific conditions of patients,such as the number and running course of the feeding arteries,lesion locations,and the vascular conditions of the draining veins.
