5 reasons why Transcranial Doppler should be considered for Cryptogenic Stroke

The reason of why transcranial doppler should be considered for cryptogenic stroke.

1. This test is highly sensitive with close to 100% detection rate for right to left shunt (detection of patent foramen ovale or atrial septal defect) compared to transthoracic echocardiogram which may be less than 50%
2. The test is expeditious, non-invasive and safe and done in a clinical setting
3. Allows grading of severity of the shunt and predicting risk of stroke
4. Able to predict and prognosticate stroke risks in patients who are managed without device closure
5. Supported by a wealth of clinical evidence and research (both locally and internationally)
