Ectasia of both ascending (47 mm) and descending (37 mm) thoracic aortas associated with two large intraluminal chronic thrombi, first extending from the aortic arch (distal to the origin of the left subclavian artery), the second one at suprarenal abdominal aorta (proximal to …

May 17, 2016 · A, Axial (A) and sagittal (B) CT images show concentric arterial wall thickening involving left subclavian artery (solid arrows), innominate artery, and aorta (open arrows).

Mar 6, 2024 · Subclavian artery thrombosis is the formation of a blood clot within the subclavian artery, causing circulatory obstruction within the vessel's distribution area. Complete stenosis from subclavian artery thrombosis is a medical emergency, as it can lead to limb loss and stroke if not treated promptly.

Mural thrombus is found in normal or aneurysmal arteries. Treatment options include anticoagulation, exclusion, or thrombectomy.

(b) axial, (c) coronal and (d) sagittal oblique post-IV contrast-enhanced MDCT demonstrates a saccular aneurysm (arrow) containing mural thrombus (dashed arrow), arising from the Kommerell diverticulum of an anomalous right subclavian artery (arrowheads) in a left-sided aortic arch.

CT clearly shows mural calcification and low-attenuation crescenteric or concentric thrombus with irregular margins and contiguous interface with aortic lumen. Large aneurysms can compress the adjacent structures such as the superior vena cava (SVC), recurrent laryngeal nerve, esophagus, or coronary arteries.

Examination revealed tenderness in the left fingertips, some motor-strength deficits in the arm, a weak left radial pulse, and a positive bruit in the region of the left subclavian artery.

Dec 1, 2014 · Primary aortic mural thrombus (PAMT) is an uncommon condition but an important source of noncardiogenic emboli with a difficult diagnosis and a high rate of complications, including high mortality. We report our experience of thromboembolic disease from PAMT and review its contemporary management.

Thoracoabdominal computed tomography (CT) showed extensive mural thrombus extending from the proximal aortic arch to the descending aorta and the celiac trunk, which developed as a result of atherosclerotic aortic lesions.

We present the case of a 53-year-old patient with a giant floating thrombus in the aortic arch associated with proximal stenosis of the left subclavian artery diagnosed by multimodal...
