Abstract

Background: Clinically silent circulating microemboli can be detected by transcranial Doppler sonography. Case Description: We report the case of a 45-year-old man with congenital cyanotic heart disease, elevated haematocrit, low platelet count and decreased protein C and protein S activity. Beforeand following several haemodilutions, we performed 5 1-hour transcranial Doppler recordings from one or both middle cerebral arteries (MCAs) on different days. The number of microembolic signals per hour varied from 54 to 134. During the bilateral recording, the microemboli occurred on both sides (55 in the right and 45 in the left MCA, respectively). There was no relation to red blood cell count, platelet count, the spontaneously lowered prothrombin time or the spontaneously prolonged activated partial thromboplastin time. Conclusions: The origin of the large number of microembolic signals found in this patient remains unclear, but may be presumed in the intra-abdominal or crural venous system.
