Abstract

The purpose of this study was to assess the feasibility and safety of thrombus-aspiration through a 5 Fr guiding catheter with transradial approach in acute coronary syndromes. The use of thrombus-aspirating devices improves myocardial reperfusion but requires at least a 6 Fr guiding catheter. Transradial coronary interventions using a 5 Fr guiding catheter are attractive to reduce bleeding complications. We retrospectively selected patients presenting acute coronary syndromes with angiographically visible thrombus who underwent thrombus-aspiration through radial access using a 4 Fr multipurpose catheter in a 5 Fr guiding catheter. We described clinical and angiographic characteristics of the cohort, and the procedure's technique, success and complications. Among the 34 included patients, 29 presented ST-segment elevation myocardial infarction. Complete resolution of the ST-segment elevation was effective in 93% of these patients. TIMI flow grade after thrombus-aspiration was significantly improved compared to baseline TIMI flow grade or after passage of the guidewire (P < 0.001 for both). There was no dissection or perforation but we noted distal embolization in 5 cases probably explained by the high grade of intracoronary thr...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
