Hi, thanks for writing to HCM.
To my knowledge, there is no correlation between angioplasty
(stenting) procedure and a cervical nerve
Propably, your husband could be having a cervical disc disease
which might be causing pain in the arms.
An MRI scan of the cervical spine
is necessary to establish the diagnosis.
Consult an orthopedic surgeon for further workup and management.
Hope this information is helpful. Good day
