Acute and Subacute Iliofemoral and/or Caval Deep Vein Thrombosis: Evaluation of Mechanical Thrombectomy Systems

Официальное название

Acute and Subacute Iliofemoral and/or Caval Deep Vein Thrombosis: Evaluation of Mechanical Thrombectomy Systems in a Monocentric, Observational Retrospective and Prospective Study (ASTER Study)

Обзор

This is a physician-initiated, observational, monocentric, retrospective and prospective Study. The study is intended to assess the feasibility of mechanical thrombectomy of caval and iliofemoral veins according to normal clinical practice in adult patients with symptomatic acute or subacute ileofemoral or caval deep vein thrombosis objectively diagnosed with CT scan imaging.

Подробное описание

Subjects with bilateral DVT may be enrolled, so long as the study limb(s) meet inclusion/exclusion criteria, including IVC patency. It is recommended that in a subject with bilateral DVT, central imaging be performed prior to treatment to evaluate the status of the IVC.

All the visits and procedures described will be performed according to the diagnostic and therapeutic assignment required by clinical practice for the patients under study. Therefore, the choice of assigning the patient to the diagnostic and therapeutic procedures deemed most appropriate for each case is completely independent of the study.

Anticoagulation therapy with enoxaparin sodium (1 mg/kg twice a day) shall be initiated at least 48 hours prior to initiation of study treatment. Hemoglobin, INR, and platelet count must be obtained within 24 hours prior to the mechanical thrombectomy procedure in order to confirm eligibility. The access site is determined by the extent of occlusive disease. When treating a single limb at time, access via the popliteal vein is reasonable.

Upon completion of study treatment, the catheter and sheath shall be removed and hemostasis obtained with pressure over the insertion site followed by placement of a pressure dressing. PCB shall remain placed on both legs until hospital discharge. Anticoagulation therapy with weight based enoxaparin sodium shall also be continued through discharge. The following assessments should be performed following the completion of study treatment, according to the normal clinical practice:

* Duplex imaging (within 24 hours of the completion of treatment) * Laboratory tests (within 24 hours of the completion of treatment) * Collection of Adverse Events
