Endovascular Emergency Thrombolysis is a minimally invasive treatment that dissolves abnormal blood clots in blood vessels to help improve blood flow and prevent damage to tissues and organs.When blood does not flow smoothly through a vessel, it can begin to coagulate, turing to a blood clot. It may continue to grow, blocking off the blood supply to certain parts of the body and causing damage to tissues and organs
- In a catheter-directed thrombolysis procedure, x ray imaging is used to help guide a special medication or medical device to the site of blood clots to dissolve the blood clot
- Catheter-directed thrombolysis is used to treat blood clots in arteries and veins resulting from any of these causes:
- Thrombosis in the vascular bed of the diseased arteries, such as thrombosis in an arm or leg artery that has severe narrowing due to atherosclerosis
- Bypass thrombosis
- Deep vein thrombosis, a condition in which a blood clot forms in a main vein that returns blood flow from the arms or legs back to the heart and lungs.This type of clot may grow big enought to completely block the vein, posing serious risk if part of it breaks off and travels to the lung (called pulmonary embolism)
- Technically successful thrombolysis requires the catheter to be placed in a stable position near by the clot. This means that the catheter tip is situated so that the clot-dissolving agent can reach the site of the obstruction.
- In some cases, the procedure is not technically possible.
- It is important to understand that clot removal alone cannot repair tissue already damaged by lack of circulation.
- Further treatment may be required, both for the underlying condition that caused the clot and for any damage to affected organs or other tissues
