61-year-old male, smoker and hypertensive, who comes to the emergency department for sudden loss of strength and tingling sensation in the right hand lasting about 15 minutes, with almost complete recovery afterwards. ECG: sinus rhythm at 93 bpm. In relation to the most probable diagnosis, indicate the FALSE answer:
The case is a TIA (transient ischemic attack). The basic etiological study includes echodoppler of supra-aortic trunks +/- cerebral arteries, echocardiogram and directed blood analysis.
A probable cause is an arterioarterial embolism due to detachment of a carotid plaque.
Doppler ultrasound of supra-aortic trunks is not very useful for diagnosis.
A cranial CT scan is necessary to assess the impact on the brain parenchyma.
Surgical treatment is indicated if imaging tests reveal carotid stenosis >70%.
