Table 4:
Averages of total fluoroscopic time, number of DSA frames, DAP, and maximum ESD for each target lesion
| Variable | Target Lesions |
|||
|---|---|---|---|---|
| AN (n = 86) | AVF (n = 7) | CCF (n = 6) | AVM (n = 4) | |
| Total fluoroscopic time, min | 59.8 ± 33.7 | 120.3 ± 67.3 | 125.9 ± 27.3 | 40.0 ± 8.7 |
| Total no. of DSA frames | 812 ± 22 | 1405 ± 758 | 1125 ± 251 | 1141 ± 320 |
| DAP, Gy × cm2 | 233 ± 132 | 380 ± 166 | 428 ± 233 | 307 ± 36 |
| Maximum ESD, Gy | 1.8 ± 1.1 | 2.0 ± 1.0 | 2.6 ± 0.9 | 1.6 ± 0.5 |
Note:—Data are given as average ± SD. AN indicates cerebral aneurysm; AVF, dural arteriovenous fistula; CCF, internal carotid artery cavernous sinus fistula; AVM, arteriovenous malformation; DSA, digital subtraction angiography; DAP, dose area product; ESD, entrance skin dose.
