In-stent thrombosis following DDAVP administration: case report and review of the literature.
Review
Overview
abstract
A 67-year-old man with a drug-eluting stent in his proximal left anterior descending artery was admitted to the hospital after sustaining a traumatic injury to the skull. Due to persistent bleeding from a subgaleal hematoma, intravenous 1-desamino-8-D-arginine vasopressin (DDAVP) was administered. Five hours later, the patient complained of crushing chest pain. A 12-lead electrocardiogram demonstrated 2 mm ST-segment elevations in the precordial leads with reciprocal depressions in the inferior leads. Emergency cardiac catheterization demonstrated total occlusion of the proximal left anterior descending stent with TIMI 0 flow. Another drug-eluting stent was placed inside the original stent with restoration of TIMI 3 flow. During the catheterization, the patient became progressively hypoxic and hypotensive requiring intubation, dopamine drip, and placement of an intra-aortic balloon pump. The patient's hospitalization was complicated by prolonged shock requiring inotropes and vasopressors. This is the first reported case of an ST-elevation myocardial infarction due to in-stent thrombosis occurring after DDAVP administration. Though DDAVP is well tolerated and efficacious in treating several types of coagulopathies, this case illustrates its potential pro-thrombotic effects. Therefore, DDAVP should be used with caution in patients with known coronary artery disease and coronary stents.
