Aim: To identify the predictive signs of aortic valve involvement on the non-electrocardiogram (ECG) gated admission computed tomography (CT) of patients with Type A aortic dissection (AD) according to the Stanford classification.Platon, AlexandraBernard, StephanePerrin, NilsMurith, NicolasJohn, ...
Aortic dissection, sometimes referred to as a dissecting aneurysm, is most commonly initiated by a circumferential tear in the intima, allowing blood flow to spill between the medial layers of the artery wall, which could propagate proximally or distally. ...
Fig. 4:Contrast enhancedCT in a patient with type A aortic dissection. In thesagitalMIP (a), the true lumen can be recognized anteriorly, with the false lumen occupying most of the aortic diameter. Intimal calcifications ...
AorticDissection,AD 即主动脉夹层。主动脉 内膜局部撕裂,受到强有力 的血液冲击,内膜逐步剥离、 扩展,在动脉内形成真、假 两腔。从而导致一系列临床 症状,如胸背部撕裂样疼痛 等。 Aorticaneurysm:主动脉壁中层受损, 弹力纤维断裂并导致血管局部或弥漫性的 ...
The aim was to compare computed tomography (CT) features in acute and chronic aortic dissections (AADs and CADs) and determine if a certain combination of imaging features was reliably predictive of the acute versus chronic nature of disease in individual patients. Consecutive patients with aortic...
A case of acute Stanford Type B aortic dissection associated with organ malperfusion requiring multi-stage surgery A 60-year-old man developed right leg pain and chest discomfort.CT showed an acute Stanford Type B aortic dissection;the dissection extended from the desce... Y Narahara,A Bito,N...
Aortic dissection (see the image below) is defined as separation of the layers within the aortic wall. Tears in the intimal layer result in the propagation of dissection (proximally or distally) secondary to blood entering the intima-media space.
Pain: The onset of acute aortic dissection is sudden, and greater than 90% of patients experience sudden severe tearing or knife like pain in the anterior chest, back or the abdomen, and the pain can be transferred along the aorta towards the upper or lower abdomen. Sudden Death: When the...
摘要: 目的 评价CT血管造影(CTA)在诊断B型主动脉夹层(AD)再破口中的价值. 方法 分析110例典型B型AD患者的CTA增强扫描及其中70例主动脉数字剪影血管造影(DSA)检查的影像资料,分别统计夹层再破口的数量、位置、大小,对两种检查的结果 采取Kappa一致性检验. ...
We studied seven patients with descending aortic dissection (type B) and four patients with penetrating aortic ulcer over a median follow-up period of 254 days during the years 1997-2000, using cross-sectional CT to evaluate the extent of the dissection, the distance between the entry tear and...
