WebMar 28, 2024 · Lindegaard ratio (LR): The LR is a calculated value that normalizes the MCA velocity to the ICA. This is calculated by the mean velocity of the MCA divided by … WebJul 19, 2013 · Mean TCD in the middle cerebral arteries (MCA) showed no difference. The Lindegaard ratio was higher in the N-group (p<0.04). CBF in the N-group was higher than in the C-group (p<0.03). Even though nitroglycerin reduces blood pressure and lowers ICA TCD-values and increases the Lindegaard ratio, a higher CBF was measured in the N …

The Lindegaard ratio was less than 3, showing absence of vasospasm. Serial TCD examina-tions (TCD images, Figure 3 (a–d)) revealed a gradual decrease in Vs, Vd and TAV mean velocities and a rise in PI and RI over a period of four days (Table 1). The TCD performed on Day 3 revealed near normal values of flow velocities, and PI and RI. current recruiting rankings
