Abstract
Background: In the presence of new neurological findings occurring after cardiac surgery, the clinical question is whether to exclude symptomatic intracerebral hemorrhage (ICH), particularly in the context of routine postoperative anticoagulation treatment. Methods: This is a retrospective 14-year study including 5,275 patients who underwent cardiovascular surgery. The control cohort included all patients with acute cerebrovascular accidents hospitalized in 2 general hospitals in Jerusalem during a 2-month period in 2007 (part of a national survey). Results: After cardiac surgery, 78 patients developed ischemic strokes, mostly of large-vessel etiology. These ischemic strokes occurred more often in patients who underwent combined operations (22/647 = 3.4% vs. 45/3,489 = 1.3%; p = 0.0004). ICH was found in 6% of all acute cerebrovascular accidents in the general survey, but was absent after cardiac surgery (5 vs. 0; p = 0.02). Conclusions:Despite hypertension as a main risk factor and the administration of postoperative anticoagulation, we found that symptomatic ICH did not occur after cardiac surgery.
