Urgent Mechanical Thrombectomy by Indigo System® in Acute Thrombosed Popliteal Artery Aneurysms: A Report of Two Cases.

The aim of this study is to report the outcome of immediate and direct revascularization by mechanical thrombectomy in acute limb ischemia due to thrombosed popliteal artery aneurysm (PAA). Two patients with acute limb ischemia due to PAA thrombosis were admitted at our hospital, and immediately treated by mechanical thrombectomy (Indigo System). The first patient had a complete recanalization after thrombectomy, while the second one required urokinase infusion (12 hr) due to a suboptimal result. After revascularization, both patients were treated by a polytetrafluoroethylene bypass to definitively exclude PAA. Follow-up showed the patency of the femoropopliteal bypass with good distal outflow. In these 2 reported cases, the Indigo System® has proven to be safe and effective, allowing an immediate limb reperfusion, reducing the necessity for thrombolytic drug infusion.
