Complications include covered stent migration, persistent leakage of blood into the pseudoaneurysm, fracturing (breaking) of the stent, and infection of the stent or of the arterial insertion site.<ref name="doi:10.1590/S1677-54492008000300016"></ref> Another option for treatment is ultrasound probe compression of the neck of the pseudoaneurysm. The "neck" of the pseudoaneurysm is the narrow path of blood flow between the artery, through the
