The transradial approach has increasingly been used for neurointerventions because of the improved safety profile compared with transfemoral. However, it is important to be aware of potential complications such as radial artery (RA) spasm, RA occlusion, pseudoaneurysm, extravasation, arteriovenous fistula, and wrist hematoma as well as their management. ⋯ Transradial access for neurointervention has a low rate of local complications, particularly when taking appropriate prevention measures. Appropriate management of complications can prevent procedural failure and has low morbidity rates demonstrating the overall safety profile of transradial access even when complications occur.

Spinal cord stimulation (SCS) effectively reduces opioid usage in some patients, but preoperatively, there is no objective measure to predict who will most benefit. ⋯ We present the first machine learning-based models for predicting reduction or stabilization of opioid usage after SCS. The DNN and 5-variable LR models demonstrated comparable performances, with the latter revealing significant associations with patients' pre-SCS pharmacologic patterns. This simplified, interpretable LR model may augment patient and surgeon decision making regarding SCS.
