Figure 1
Figure 1 Schematic representation of thrombus fragmentation by a mechanical thrombolysis resulting a distal embolization of smaller thrombi, creating a larger surface area of the clot improving the efficacy of the thrombolytic agent therapy.

Figure 2 The great advantage of these devices although of dubious effectiveness, is that they are simple to use and available at a low price. A, B: Pulmonary angiography and CT angiography, of a 37-year-old male patient diagnosed with a massive pulmonary embolism; C: Catheter drug therapy, and mechanical thrombolysis; D, E: Schematic representation of mechanical thrombolysis and the infusion of fibrinolytic agents through the pigtail catheter; F: Pulmonary angiography after 24 h of perfusion with 100000.00 UI/h of urokinase, showing no residual occlusion.

Figure 4 The Indigo mechanical aspiration system (Penumbra Alameda, United States) is an aspiration thrombectomy catheter system. A, B: Pulmonary angiography and CT angiography, of a 37-year-old male patient diagnosed with a massive pulmonary embolism, 24-year-old female patient diagnosed with massive pulmonary embolism; C-F: Treated with CAT8 and SEP8 Indigo System® by PENUMBRA and catheter directed therapy with Pig-tail catheter with an infusion of 1200000.00 UI urokinase administered in 12 h. CT: Computed tomography.

Figure 5 EKOsonic Endovascular System by BTG. Specialized catheter that lodges in its interior a sophisticated mechanism that haves an ultrasonic core to effectively target an entire clot producing thrombolysis effect, and also helps the infusion of the fibrinolytic agent work faster and more efficient.
