Dextran Use for Primary Angioplasty Protection in Acute Myocardial Infarction

"Patients will be treated in the occluded coronary with a solution of venous blood and Dextran, prior to the Stenting procedure.~Controlled Reperfusion PCI consists of crossing the culprit lesion with guidewire and then advancing a balloon (over the wire) to the distal segment of the culprit vessel. Proximal to the main distal branch, inflate the balloon to low atmospheres, remove the guide wire and inject the solution through the light of the balloon. Then reposition the guidewire, perform angioplasty as usual on the lesion. If there is a large residual thrombus load and at the operator's discretion, change the balloon by a manual thromboaspiration catheter and use it.~Then perform stenting of the lesion. The solution will be given with a 1 cc syringe as a slow bolus, controlling symptoms and ST segment response.~The compounds in solution are venous blood drawn from the patient after administration of heparin and mixed with dextran in a 3/1 ratio."
