Answer

Percutaneous mechanical thrombectomy devices are a popular adjunct to catheter-directed thrombolysis. Although these devices may not completely remove thrombus, they are effective for debulking and for minimizing the dose and time required for infusing a thrombolytic. Percutaneous mechanical thrombectomy has developed as an attempt to shorten treatment time and avoid costly ICU stays during thrombolytic infusion. The most basic mechanical method for thrombectomy is thromboaspiration, or the aspiration of thrombus through a sheath. Mechanical disruption of venous thrombosis has the potential disadvantage of damaging venous endothelium and valves, in addition to thrombus fragmentation and possible pulmonary embolism.
