Complications of PPSI under CT guidance are rare :

Meningitis with neurologic damage ( quadriplegia, multiple cranial nerve palsies, nystagmus…) are described after epidural or intrathecal injection of steroids if strict sterility is not respected. With precise CT monitoring accidental intrathecal injection can be avoided. Severe sterility during the intervention is mandatory.
There is a risk of calcifications by using triamcinolone hexacetonide as long acting steroid. We do not recommend the use of this steroid.
For cervical level, vertebral artery injury or intra-aterial injection are described. This can be avoided by precise CT control.
