The Cutting Edge in Diagnosis and treatment of Stroke (Paralysis)Stroke
Stroke is a condition where the blood supply to a part of the human brain is either Interrupted or blood clots outside blood vessels due to hemorrhage.TCD
Stands for Transcranial Doppler. It is a form of ultrasonography and is used in the diagnosis of Stroke along with the CT Scanner, MRI and MRA.
It is a test that meas-ures the velocity of blood flow through the brain`s blood vessels. It is used for the diagnosis of stroke, emboli, stenosis, vasospasm from a sub-arachnoid hemorrhage and bleeding from a ruptured aneurysm. This test is relatively quick and can be done at the patient’s bed-side unlike CT Scan & MRI, where the patient is taken to the imaging department.Advantages
TCD can be done at the bedside, is non-invasive and gives ‘real time’ (means instant) imaging of the blood vessels of the brain.When done?
It is usually done to diagnose the following conditions:
Thrombolysis is a type of treatment given in stroke where clots in blood vessels are dis-solved by medicines. Use of ultrasound enhances the effect of thrombolysis. Hence thrombolysis is combined with TCD Ultrasonography to get better results in cases of stroke.A preventive diagnostic test for blood vessels of Brain
