Summary

The Theia-study is a prospective, multicenter, single-arm management (cohort) study. Consecutive patients with clinically suspected acute, recurrent, ipsilateral, proximal deep vein thrombosis (DVT) of the leg, who fulfil all the inclusion criteria and meet none of the exclusion criteria, are eligible for inclusion and will be managed according to the result of a magnetic resonance direct thrombus imaging (MRDTI) of the affected leg. The MRDTI is to be performed and adjudicated within 24 hours of study inclusion. The final treatment decision will be made based on this ruling of the MRDTI. In case of a positive MRDTI signal, patients will be treated with therapeutically dosed anticoagulants or modified in patients with a recurrent DVT on anticoagulant therapy. Patients with a negative MRDTI ruling will be left untreated, or treatment will be remained unadjusted if they are on anticoagulant treatment at inclusion. All patients with negative MRDTI will be subjected to a standardized compression ultrasonography (CUS) within 48 hours after initial presentation. The latter CUS serves as a reference test in case the patient returns with symptoms of ipsilateral recurrence in the future, and will not be used for management decisions at baseline. The study flowchart can be found in Appendix A. All patients will be followed for three months for the occurrence of acute recurrent venous thrombo-embolism (VTE). In case of suspected recurrent VTE, objective testing including either computed tomography pulmonary angiography (CTPA) for PE or CUS for DVT will be performed. Additionally, in case of a proven ipsilateral recurrent DVT during follow-up, MRDTI will be repeated.
