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).

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).
