Figure 4

Correlation of the arterial diameters and angles with the maximal aneurysm size at the middle cerebral artery (MCA) bifurcation. The MCA bifurcation aneurysm maximal size was significantly (P = 0.01 or < 0.0001) positively correlated with the diameter of the smaller and larger M2 branches rather than the M1 artery. For the angles, the aneurysm maximal size was not significantly (P > 0.05) correlated with the smaller or larger lateral angles but was significantly (P = 0.04) positively correlated with the MCA bifurcation angle formed between two M2 branches.
