  • Note:—PD indicates packing attenuation; (−), coil embolization without stent (in “Stent”), unruptured aneurysm (in “Rupture status”); (+), stent-assisted coil embolization (in “Stent”), ruptured aneurysm (in “Rupture status”); L, largest diameter; P, perpendicular diameter; AUC, area under the curve.

  • ↵a Data in parentheses are 95% confidence intervals.

  • ↵b AUC values between both diameters were compared.

  • ↵c Statistically significant (P < .05).

  • ↵d Seventy-four of 78 cases had the record of packing attenuation.
