Intracoronary thrombectomy

Intracoronary thrombectomy, percutaneous treatment of coronary disease


A complex, ruptured atheromatous plaque occasionally causes the onset of clots and platelet apposition, which is commonly seen in plaques causing myocardial infarction.

The presence of fresh thrombi in the vessel we want to treat generates a high-risk situation. If we treat the plaque without first treating the clot, we could provoke embolism that obliterates fine vessels and leads to what is known as “non-reflow syndrome”; the plaque can be free from stenosis but the re-established blood flow does not reach the capillary bed that is blocked by clots. Although this is usually a temporary situation, it can seriously aggravate the patient until resolved with intracoronary adenosine and antiplatelet drugs.

To prevent this condition in patients with coronary lesions containing fresh thrombi, it is now possible to aspirate clots through catheters before stent implantation. This preventive measure often prevents distal embolism and the “non-reflow” phenomenon in patients with thrombotic lesions. These fine catheters have two spans, one to insert a thin metal guide-wire to the lesion and another connected to a vacuum to aspirate the soft clot adhered to the plaque (Figure…)
