Synopsis

The guests start by describing their typical referral patterns, noting that most cases come through the emergency department. In terms of workup, it is important to distinguish between acute and chronic DVTs and classify the thrombosis location as either proximal (femoral vein or higher) or distal. Anticoagulation, usually with direct oral anticoagulants, is always started, with efficacy largely determined by patient compliance.

Regarding endovascular intervention, thrombolysis may be an effective adjunctive treatment if the clot occurred within a two-week timespan, but it carries a bleeding risk and requires ICU monitoring. On the other hand, mechanical thrombectomy is an option for both acute and chronic clots, allows for intervention in patients with high bleeding risk, and does not require post-procedural hospitalization. Both physicians emphasize that interventions should be employed if there are long-term benefits of avoiding post-thrombotic syndrome and pulmonary embolism.

The physicians walk through a typical mechanical thrombectomy procedure, which involves the thrombectomy device, venogram, intravascular ultrasound, and possible stent placement. Finally, they discuss recent data, including the ATTRACT Trial for thrombolytics and the CLOUT Registry and Trial for ClotTriever use. Notably, they mention the DEFIANCE Trial as a current prospective randomized clinical trial for ClotTriever use in the iliofemoral region.
