Acute and Subacute Iliofemoral and/or Caval Deep Vein Thrombosis: Evaluation of Mechanical Thrombectomy Systems
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.
- EligibilityCriteria: Inclusion Criteria:  Patient admitted in Unit of Vascular Surgery, San Raffaele Hospital, Milan Patients able to sign specific informed consent for the study Age 18 years to 75 years Proximal DVT (inferior vena cava, iliac vein, common femoral vein, deep femoral vein, and femoral vein) that was objectively diagnosed with CT scan Symptomatic DVT (pain, neurological deficit) or imparement of the tissue perfusion (phlegmasia) Diagnosis of the DVT since 1 month prior to the index procedure  Exclusion Criteria:  Patient treated with mechanical thrombectomy in the two week prior to the index procedure Patient treated with thrombolysis drugs within 48 hours prior to the index procedure Life expectancy less than (<) 1 year Body Mass Index (BMI) greater than (>) 40 kilograms/square meter (kg/m^2) or per Investigator's discretion participant is able tolerate the procedure and be compliant with post-procedure increased physical activity. Active bleeding, recent (<3 months) gastrointestinal (GI) bleeding, active peptic ulcer, severe liver dysfunction, and bleeding diathesis Recent (<3 months) internal eye surgery or hemorrhagic retinopathy; recent (<10 days) major surgery, cataract surgery, trauma, cardiopulmonary resuscitation (CPR), obstetrical delivery, or other invasive procedure History of stroke or intracranial/intraspinal bleed, tumor, vascular malformation, or aneurysm Active cancer (metastatic, progressive, or treated within the last 6 months).
