Objective
We present a novel strategy in cardiac surgery with a cardiopulmonary bypass with low-dose heparin and Nafamostat mesylate as an anticoagulant (NM-CPB), which reduces postoperative neurological complications.
Method and results
19 patients with a mean age of 63.6 ± 20.2 years (range 24–91) and an indication of early cardiac surgery with intracranial complication (ICC) underwent surgery with NM-CPB. The preoperative diagnoses included seven cases of infective endocarditis and six of left atrial appendage thrombosis. ICC were noticed in seven cases with hemorrhages (hemorrhagic infarction: n = 4, subarachnoid hemorrhage: n = 3) and 12 without hemorrhage (large infarction: n = 10, small-multiple infarction at the risk for hemorrhagic transformation: n = 2). The mean interval between a diagnosis and cardiac surgery was 1.1 ± 1.5 days in the ICH cases and 1.4 ± 1.4 days otherwise.
In-hospital mortality was 5.3%. The mean CPB time was 146.7 ± 66.03 min, the mean dose of NM, heparin were 2.23 ± 1.59 mg/kg/hr and 56.8 ± 20.3 IU/kg, respectively. The mean activated clotting time (ACT) was 426.8 ± 112.4 s. No further intracranial bleeding and no new hemorrhages were observed after surgery.
Conclusions
In early cardiac surgery with ICC, especially with hemorrhage, NM-CPB reduced postoperative neurological complications. We plan to use NM-CPB to expand the indications and to establish an early aggressive treatment.
