Figure 1.

demonstrates the relationship between the cross-sectional areas (CSA) of 0.071” and 0.088” catheters in relation to the average lumen sizes for the middle cerebral artery (MCA) M1 segment, basilar artery and cavernous segment of the internal carotid artery (ICA). The inner and outer CSAs of the 0.071” catheter cover 43.5% and 59.2%, 32.2% and 43.9%, and 22.4% and 30.5% of the lumen of the MCA-M1, basilar and cavernous ICA, respectively, versus 67.3% and 95.7%, 49.9% and 71%, and 34.7% and 49.4% coverage with the inner and outer CSAs of the 0.088” catheter.
