1) Reviewing the pathology and outcomes of children with spinal muscular atrophy (SMA)
2) Learning the procedures available for intrathecal access
3) Understanding the indications for choosing more advanced techniques to deliver nusinersen

Spinal muscular atrophy is an autosomal recessive disease affecting motor neurons and is the most common genetic cause of death in infants. Nuinersen (Spinraza) was recently approved by FDA for intrathecal administration in SMA patients. Commonly administered by lumbar puncture in the clinic or with imaging guidance, this is the initial method of administering nusinersen. Deformities and spinal instrumentation from orthopedic surgeries are common in SMA patients, preventing traditional intrathecal access by lumbar puncture for nusinersen delivery. Transforaminal lumbar sac access, ultrasound or fluoroscopy guided cervical spine access, or subcutaneous catheter placement can be the alternative approaches with failed/difficult lumbar access. Given the potential benefit of nusinersen, understanding all methods to obtain intrathecal access is essential for a pediatric interventional radiology (IR) practice. Read More
