Plethysmography: A game changer for chronic venous insufficiency diagnosis, treatment, and follow-up.

D-PPG shows potential as a valuable tool in the diagnosis and treatment of CVI. By providing information about venous hemodynamics and volume changes, it can assist in optimizing treatment decisions, including saphenous vein preservation. Combining D-PPG with Doppler USG may improve the comprehensive assessment of CVI and change the treatment option, especially for CEAP 2 patients. More research is needed to confirm these findings and explore wider applications of plethysmographic methods in the management of CVI.
