The purpose was to evaluate CT findings of @entity548 extending along the pulmonary artery (PA) due to @entity1755 ( @entity1580 ) and its prognostic factors. In 232 @entity1 with Stanford type A @entity1580 , 21 @entity1 (9.1%; 11 @entity1 ; mean 70.3 years) were diagnosed. Twelve @entity1 had double-barreled (classic) @entity1580 , and nine @entity1 had @entity1410 ( @entity1410 ; closed false lumen) of the aorta. Based on CT findings, @entity548 was classified into three categories as follows: category 1 ( @entity1410 of the PA or blood localized around the PA), category 2 (extending into the interlobular septa), and category 3 (extending into the alveoli). The factors influencing prognosis, including CT features and @entity1 characteristics, were evaluated. Fourteen (66.7%) of the 21 @entity1 underwent emergency surgery, and 8 (38.1%) @entity1 died within 72 h of onset. Twelve cases (57.1%) were classified into category 1, 2 cases (9.5%) into category 2, and 7 cases (33.3%) into category 3. Double-barreled @entity1580 and category 3 @entity548 were significant risk factors for @entity204 in univariate analyses. In multivariate analyses, the presence of category 3 @entity548 was the only significant risk factor for @entity204 . CT findings indicative of a poor prognosis include double-barreled type @entity1580 and category 3 @entity548 .
