[Intracoronary thrombolysis. A case report].

Restoration of blood flow in an occluded right coronary artery of a patient with an acute myocardial infarction was achieved with intracoronary administration of streptokinase. Patency of the vessel was restored within 15 minutes after starting the infusion. The dose of streptokinase used was 3000 U/min. The patient's pain was relieved and the raised ST segments returned to normal after patency was achieved. Cardiac output and stroke volume increased fro 3,6 to 6,3 1/min and from 61 to 70 ml respectively. No complications occurred during the infusion of streptokinase. Intracoronary thrombolysis might well establish itself as the treatment of choice for acute myocardial infarction in selected patients.
