Isolated distal deep vein thrombosis (IDDVT) is a frequent manifestation of venous thromboembolism (VTE), accounting for up to 50% cases of lower‑extremity deep vein thrombosis (DVT). As compared with proximal DVT, IDDVT is more frequently associated with transient risk factors and less often occurs unprovoked or in the presence of permanent risk factors. IDDVT generally carries a significantly lower risk of proximal extension, post‑thrombotic syndrome, and recurrence than proximal DVT. ⋯ Recent results of the RIDTS (Rivaroxaban for the Treatment of Symptomatic Isolated Distal Deep Vein Thrombosis) randomized clinical trial with rivaroxaban further support the use of anticoagulant therapy for 3 months over shorter durations (eg, ≤6 weeks). In this review, we offer an updated overview of the epidemiology, risk factors, and clinical course of IDDVT, with a focus on the therapeutic management in light of current guideline recommendations and most recent evidence. We also present real‑life clinical cases of IDDVT with proposed therapeutic approaches, and highlight major challenges and gaps in this field.
