2.2 | Treatment
The patient was placed under general anesthesia to undergo superselective angiography and endovascular embolization. A right groin common femoral artery puncture was performed for vascular access using a 5-French sheath. Superselective angiography and endovascular embolization with n-butyl cyanoacrylate of the Th11 radicular artery were performed. Complete angiographic obliteration of the fistula was achieved (Fig. 4).
2.3 | Outcome and follow-up
The patient also experienced immediate improvement in sensory symptoms, which progressed with each postoperative day of recovery. The patient was discharged from the hospital 2 weeks after the treatment. Postoperative MRI revealed the expected improvement in spinal cord edema and the disappearance of abnormally dilated vascular flow voids around the spinal cord (Fig. 5a).
