Methods and devices for mechanical thrombus extraction
|
Type of thrombus extraction |
Device | Mechanism of action | Benefits | Limitations |
Possible complications |
| Balloon | Balloon catheter, Fogarty HyperForm |
Removal of large fragments of a thrombus |
Ability to create channels within a thrombus |
Partial hooking of blood clot |
Pulmonary embolism |
| Reolitic | AngioJet | Gradual destruction of the clot with a pulsating jet of saline, aspiration |
Aspiration with devices |
Difficult navigation due to catheter rigidity, possibility of perforation of venous collectors |
Blood loss, hemodilution |
| By aspiration |
Penumbra System |
Gradual destruction of the thrombus, aspiration |
Adequate distal navigation, rapid destruction of the thrombus, Aspiration with devices |
||
| Mechanical | Stent Solitaire AB |
Fragmentation of the thrombus, removal by parts |
Easy navigation of sinuses, reliable hooking of blood clot |
Manual aspiration from guide catheter |
Pulmonary embolism unlikely |
