    Abstract:
    Objective Thromboembolic events such as acute coronary syndrome related prosthetic heart valve thrombosis, pulmonary artery embolism and renal artery embolism are a rare condition but a major cause of morbidity and mortality. In this study we discussed low-dose thrombolytic therapy, in patients with thromboembolic events in the intensive care unit.Methods The study was performed on 12 consecutive patients [8 female; 50.3±16.0 (35-95) years] with acute thromboembolism including acute coronary syndrome related prosthetic heart valve thrombosis, acute pulmonary embolism and acute renal embolism who were treated with low-dose (25 mg) and slow infusion (6 hours) of t-PA. We evaluated mainly in-hospital safety and also effectiveness.Total treatment episodes was 1.66±0.88 (1-4) times.Results All thromboembolic events have been successfully treated with low-dose (25 mg) and slow infusion (6 hours) of t-PA. The success criteria were clinically improvement and radiologically lysis. None of the patients had ischemic stroke, intracranial hemorrhage, embolism (peripheral and recurrence of coronary artery embolism), bleeding requiring transfusion. The most frequent in-hospital complication was a gum bleeding without need for transfusion (two patients).Conclusions In our case series low-dose (25 mg) and slow infusion (6 hours) of t-PA have been performed successfully for thromboembolic events including acute coronary syndrome related prosthetic heart valve thrombosis, pulmonary embolism and renal embolism in patients with in the intensive care unit. Safety is promising and if efficacy will be proved; this method may be a valuable alternative to standard fibrinolytic regimen.
