There have been some research papers about balloon venoplasty:

Factors influencing the hemodynamic response to balloon angioplasty in the treatment of outflow anomalies of internal jugular veins - General / Research Papers - Living with Eagle

DA ZHOU et al. (2018) - Understanding jugular venous outflow disturbance - General / Research Papers - Living with Eagle

There might be more, I think there have been papers reviewing the effectiveness of different treatments, that was just a quick search in case you’re interested!
