“…On the other hand, sometimes contrast media from a previous study remains in the aortopulmonary adventitia and is seen as a high density lesion. This should be differentitated from hemorrhage (6). Therefore, if any contrastenhanced CT was performed before CT aortography, physicians should consider the effect of previously injected contrast media.…”

Hemorrhage extending to the pulmonary artery is an uncommon complication of Stanford type A aortic dissection that has a poor prognosis. Diagnosis of this complication is mainly dependent on imaging studies, especially computed tomography. High attenuation can be seen along the wall of the pulmonary artery on the non-enhanced study, while the enhanced study shows luminal narrowing and wall thickening of the pulmonary artery. We report three cases with different imaging findings of hemorrhage extending to the pulmonary artery from Stanford type A aortic dissection.

“…It can occur when the posterior wall of an aorta is ruptured because the pulmonary trunk and ascending aorta have a common adventitia (1,2). Only a few reports were published previously on this subject (2)(3)(4)(5)(6). It can be diagnosed by an imaging study such as computed tomography (CT).…”

“…It is well described that these two vessels share a common “sheath” of mediastinal connective tissue. 5 Any rupture of the aortic adventitia may cause hemorrhagic infiltration along this tissue, which may erode the wall of the PA, causing rupture, aortopulmonary fistulas, 6 and in some cases occlusion of the PA. 7 …”

“…Previous reports have suggested that HPS is a common complication of Stanford-A AAD [14]. Due to the poor evidence, previous studies used different terms to describe this complication such as intrahepatic hematoma [15,16], pulmonary sphincter hematoma [17], blood infiltration of the aorta and pulmonary vascular adventitia [18], and hemorrhage along the pulmonary sheath [19], extraluminal perivascular hemorrhage [20], and hemorrhage along the pulmonary artery [21][22][23]. The results of HPS in chest radiographs examination varies according to the range of bleeding (normal to double lung flaky infiltration) [24][25].…”

Background: AAD refers to the blood flow into the middle membrane through the intimal rupture of the aorta. Hemorrhagic pulmonary sheath (HPS) is a common complication of Stanford-A AAD. The risk factors of HPS are remaining unclear Methods: In this study, we have probed the potential risk factors of HPS patients with acute Stanford A aortic dissection. 18 HPS patients with acute Stanford A aortic dissection were selected as the case group. The age difference ± 5 years and the same sex are set as the matching principles. 36 patients with acute Stanford-A type AD who did not detect HPS in the same period were matched according to the ratio of 1:2. Demographic data, treatment methods, AD-related disease history, clinical symptoms and Charlson comorbidity index (CCI) values of each patient were collected. Meanwhile, the values of the maximum diameter of ascending aorta (mm), aortic dissection range, and the main branch of the aorta, pleural effusion/blood, and pericardial effusion/blood were measured by two experienced cardiovascular radiological physicians. Univariate and multivariate conditional logistic regression analysis was used in this study. Results: CCI value and the branches of the brachiocephalic in the case group were significantly higher than those in the control group (p<0.05). Univariate conditional logistic regression analysis showed CCI and branches of the brachiocephalic were associated with HPS. Multivariate conditional logistic regression analysis suggested that branches of the brachiocephalic were an independent risk factor for HPS (OR=7.02, 95%CI=1.28-38.62, p=0.025). Conclusions: Branches of the brachiocephalic were an independent risk factor for HPS.
