Abstract

Malignant ischaemic stroke is primarily caused by large hemispheric infarctions resulting from cardioembolic or thrombotic causes. These hemisphere infarcts are often caused by occlusions of the internal carotid artery (ICA) or the middle cerebral artery's proximal segment (stem or M1 segment).When the accumulation of blood & edema around the injured brain tissues exerts enough pressure to cause the entire brain to shift off-center, this is known as a midline shift. This is a warning sign & is regarded as a medical emergency.When measuring midline shifts, three primary structures are frequently evaluated. The most crucial of them is the thin, linear layer of tissue between the left & right ventricles called the septum pellucidum. Its distinct hypodensity makes it simple to detect on CT or MRI imaging. The 3rd ventricle & the pineal gland, which are both centrally positioned and caudal to the septum pellucidum, are the other two important midline structures.
The gold standard for MLS detection is the CT scan.
The temporal acoustic bone window allows for the measurement of the ultrasound MLS.

AIM:
This study aimed to assess the predictive value of early transcranial Doppler in patients with acute ischemic stroke and to correlate different transcranial Doppler measurements with CT brain in the assessment of midline shift.
