- Embolic Signals during Routine Transcranial Doppler Ultrasonography in Aneurysmal Subarachnoid Hemorrhage(2015) PASCHOAL JR., Fernando Mendes; RONCONI, Karla de Almeida Lins; OLIVEIRA, Marcelo de Lima; NOGUEIRA, Ricardo de Carvalho; PASCHOAL, Eric Homero Albuquerque; TEIXEIRA, Manoel Jacobsen; FIGUEIREDO, Eberval Gadelha; BOR-SENG-SHU, EdsonIntroduction. Cerebral emboli may occur in subarachnoid hemorrhage (SAH) and intracranial aneurysm surgery. Although embolic signs (ES) have been reported in SAH, their origin remains unclear. The aim of this study was to report the detection of ES during routine TCD monitoring in patients with aneurysmal SAH. Methods. A total of 105 patients with aneurysmal SAH were submitted to TCD evaluation. Patients were monitored almost daily (5 times per week). In each monitoring session, one experienced operator performed TCD to detect or assess vasospasm and ES in arteries of the Willis polygon. Results. Four patients out of a total of 105 patients with aneurysmal SAH were found to present spontaneous cerebral embolization during routine TCD monitoring. The average age of the 4 patients (mean +/- standard deviation) was 59.5 +/- 8.34 years (range 49-68 ys); female patients predominated representing 75%(3/4) of subjects. Conclusion. Although detection of ES was relatively rare in this study, rates of emboli occurrence may be higher under systematic monitoring. The detection of ES after SAH surgery reinforces the need to study the role of embolus in this condition and may be an indicator for prophylactic antithrombotic treatment.
