Occlusive stroke causes permanent tissue damage over the following three hours (maybe even 4.5 hours), but not instantly. Transcranial Doppler More Sensitive, Prognostically Valuable in Diagnosing PFO. Transcranial Doppler (TCD) ultrasound is not only better than transesophageal echocardiography (TEE) at identifying patent foramen ovale (PFO), it also better predicts the risk of embolic events at 5 years. The findings were presented February 14, 2014, at the International Stroke Conference in San Diego, CA. In patients with stroke or transient ischemic attack of unclear etiology, especially in blacks, Orientals, or females, who have a higher incidence of intracranial arterial disease, TCD can be a very important noninvasive means for detecting stenosis of intracranial vessels. Transcranial Doppler sonography is a non-invasive, non-ionising, inexpensive, portable and safe technique that uses a pulsed Doppler transducer for assessment of intracerebral blood flow. This article deals with the principles and technique of transcranial Doppler sonography. Sacco et al demonstrated with TCD that in 8% of 438 patients with ischemic stroke, intracerebral atherosclerosis was the most probable cause of the stroke.

When the ultrasound-based transcranial doppler system was invented in 1982 it pledged to be the stethoscope of the brain. The technology failed to meet its vision due to the difficulty in locating 1. Stroke.

The data were presented at the 26th annual European Stroke Conference, taking place from 24–26 May in Berlin, Germany. […] Transcranial Doppler (TCD) Ultrasonography and its Clinical Application- A Review and Update Introduction Transcranial Doppler (TCD) ultrasonography is a non-invasive technique that utilised a pulsed low-frequency ultrasonic transducer of low frequency through some selected region (window) in the cranial region to enable recording to flow velocity We aimed to evaluate the predictability of transcranial Doppler (TCD) in diagnosing high‐risk PFO compared with that of transesophageal echocardiography (TEE), which is not feasible for some stroke patients.
