Morphological Parameters of Digital Subtraction Angiography 2D Image in Rupture Risk Profile of Small XXXX : A Pilot Study.

UNASSIGNED: Objective   To analyze the morphological parameters of small @entity438 using two-dimensional digital subtraction angiography (DSA) and to identify their relationship with @entity397 risk. Methods   Clinical and radiologic data from @entity1 with DSA-confirmed small @entity438 and who received intravascular treatment were retrospectively analyzed. Morphological parameters such as maximum height, transverse diameter, @entity439 width, and aspect ratio (AR) were compared between @entity1 with ruptured and @entity439 . Logistic regression analysis was performed to identify the predictors of @entity397 risk. Results   There were no significant differences between the unruptured (n   =   40) and ruptured groups (n   =   34) with respect to maximum height (p   =   0.087) and transverse diameter (p   =   0.736). However, @entity439 width (p   =   0.006) and AR (p   <   0.001) were found to be significantly different between the groups. AR value was analyzed through the receiver operating characteristic curve, and the best AR threshold was determined to be 1.49. A stepwise multivariate analysis showed that AR was the only independent factor for @entity397 risk. Conclusion   Two-dimensional DSA could be used to determine AR, which was an independent predictor of @entity397 risk of small @entity439 . Further studies with large sample sizes are needed to validate these results.
