2024年8月5日 · Aortic pseudoaneurysms are contained ruptures of the aorta in which the majority of the aortic wall has been breached, and luminal blood is held in only by a thin rim of the remaining wall or adventitia.

2024年2月17日 · Aortic Pseudoaneurysms. Aortic pseudoaneurysms due to blunt trauma are theorized to be caused in large part by deceleration forces between the relatively free aortic arch against the relatively fixed descending aorta, especially at the point where the ligamentum arteriosum anchors the aorta to the pulmonary artery.

False aneurysms of the aorta, known as pseudoaneurysms, are hematomas formed outside the aortic wall, resulting from transmural disruption with the leak contained by surrounding mediastinal tissues.

Endovascular treatment is safe and effective for thoracic aortic pseudoaneurysm. The choice of treatment should be tailored for patients, taking into consideration the etiology and location of the pseudoaneurysm.

Thoracic aortic pseudoaneurysms are rare. The main causes of aortic pseudoaneurysms are iatrogenic injury, trauma, atherosclerosis, and infection. Whereas aortic pseudoaneurysm might be asymptomatic, it is potentially fatal and may cause death of 32% to 40% if ruptured. Therefore, treatment should be considered as soon as the diagnosis is made.

2023年2月12日 · Aortic pseudoaneurysm is a life-threatening clinical condition, and thoracic endovascular aortic repair (TEVAR) has been reported to have a relatively satisfactory effect in aortic pathologies. We summarized our single-centre experience using chimney TEVAR for aortic arch pseudoaneurysms with inadequate landing zones.

False aneurysms of the aorta, known as pseudoaneurysms, are hematomas formed outside the aortic wall, resulting from transmural disruption with the leak contained by surrounding mediastinal tissues.

2018年4月25日 · Aortic pseudoaneurysm is characterised by: acute angles between cranial end and caudal end of the focal bulge and the aortic wall, a dissection flap, and haemomediastinum [4].

2019年12月1日 · An aortic arch pseudoaneurysm is a rare and anatomically challenging complication of aortic stenting. In this report, we show that endovascular coil embolization may be a feasible alternative option when the patient is not suitable for open repair or stent‐grafting.

2019年7月22日 · Traumatic pseudoaneurysms of the aortic arch are often treated with surgical repair regardless of the lesion size or age. The authors report a simple, less invasive surgical repair in a patient who sustained blunt aortic injury following a fall.
