The new X-PASTE classification for post Laser or Radio-Frequency thrombosis extension

Abstract

Post Ablation Superficial Thrombus Extension (PASTE) is
the thrombosis extension from the termination of the
saphenous trunk and in continuity with the closure postEndo-venous ablation (EVA). PASTE can occur in the
saphenous femoral junction (SFJ) or in the saphenous
popliteal junction (SPJ).
Endo-venous Heat Induced Thrombosis (EHIT) and several other terms (EFIT, EGIT, ETIT) were proposed, where F
stands for Foam, G for Glue and T for treatment.
PASTE is definitively wider than the other terms. Adding
to it an extended score, X-PASTE becomes undoubtedly
the best descriptor for post-EVA thrombosis extension.
Reconsidering the hidden features of previous scoring
methods and in analogy with their underlying principles,
the new score checks a sequence of overlapped couples of
segments, starting from the junction and going towards
the periphery
