Trial Title: Ultrasound Findings to Adjust the Duration of Anticoagulation

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* acute proximal DVT associated or not with clinically symptomatic pulmonary embolism~Exclusion Criteria:~* history of previous VTE~* active cancer~* indications for permanent anticoagulation~* contraindications to anticoagulation~* pregnancy~* geographical inaccessibility for long-term follow-up~* life expectancy shorter than 1 year~* refusal of informed consensus

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- 1 (Type: EXPERIMENTAL): Tailoring the duration of anticoagulation according to the ultrasound persistence of residual vein thrombosis
- 2 (Type: ACTIVE_COMPARATOR): Administering a fixed duration of anticoagulation (i.e., discontinue it at the time of randomization in patients with secondary DVT, and prolong it for 3 additional months in patients with idiopathic DVT)

Based on this trial design, predict the completion outcome and termination type (if applicable).
