AbstractIntraspinal drug delivery systems can be effective in controlling intractable pain. However, before these invasive pain therapies are initiated and to avoid or minimize any complications associated with their use, there must be a thorough understanding of the etiology of the pain, the underlying cancer, and antineoplastic therapy. For example, the assumption that intraspinal cannulation is contraindicated in all patients with known vertebral metastatic lesions is not supported in clinical practice. A majority of spinal metastatic lesions involve the vertebral body, which is distant from the dorsal position of the intraspinal catheter. Based on extensive experience, the only pragmatic contraindications to neuraxial infusion device implantation are those also revelant to surgical intervention. Careful patient selection may help avoid some complications and constant vigilance may be the best defense against errors.
