Mechanical Thrombectomy is a catheterization procedure used
for Thrombolysis.
"Thrombus" is a blood clot; "lysis" means to break apart. Mechanical
Thrombectomy is used to break up a blood clot that is causing
partial or full obstruction of blood flow in an artery.
Mechanical Thrombectomy is often used before angioplasty with
or without stent placement, to remove dangerous blood clots. The
angioplasty procedure is thus, much safer and more effective
once the clot has been removed.
Mechanical Thrombectomy involves a tiny catheter that is inserted
into an artery in the groin (the femoral artery). The catheter
is positioned in the peripheral artery containing the blood clot.
Once properly positioned, a pump is activated, delivering a saline
solution under high pressure through the pump jets into the artery,
and directly at the blood clot. These saline jets create a powerful
vacuum within the artery, breaking up the clot. The clot
pieces are then removed through the catheter and into a collection
bag. Once the catheter is removed from the femoral artery, pressure
is applied to stop bleeding, and the patient must rest flat for
several hours.
