Bronchiectasis due to an Ectopic Right Pulmonary Artery and Compression of the Superior Vena Cava between an Ascending Thoracic Aortic Aneurysm and Enlarged Right Pulmonary Artery

چکیده
OBJECTIVE The aim of this study was to report multidetector computed tomography (CT) imaging findings relating to segmental pulmonary arterial ectasia (PAE), which is a very rare vascular condition. CLINICAL PRESENTATION AND INTERVENTION A 70-year-old woman presented with shortness of breath and increased production of purulent sputum. Chest CT angiography revealed bronchiectasis secondary to compression of the anterior segment bronchus of the right upper lobe because of a segmental PAE. She also had compression of the superior vena cava between an ascending thoracic aortic aneurysm and an ectopic enlarged right pulmonary artery. Conventional right upper lobectomy and angioplasty were planned, but the patient refused surgical therapy. CONCLUSION This report shows the importance of CT angiography in a case that involved an unusual coincidence of segmental PAE and ascending aortic aneurysm.

Aortic root aneurysm with a persistent left superior vena cava and an absence of the origin of the right coronary artery.
Figure 1: Preoperative chest computed tomography showed an idiopathic aortic root aneurysm with a maximal size of 15 cm, greatly compressing the left ventricular outflow tract, ascending aorta, right atrium and right ventricle. There was a persistent left superior vena cava. There were no clinical findings of Marfan syndrome or Ehlers–Danlos syndrome. Figure 2: A cardiopulmonary bypass was made...

A patient with a dissecting thoracic aortic aneurysm presented with acute low output cardiac failure due to right atrial obstruction. Five years earlier she had had her aortic valve replaced because of aortic regurgitation. Obstruction of the superior vena cava and pulmonary artery has been reported elsewhere as a complication of compression by thoracic aortic dissecting aneurysm. This case was...
متن کاملAneurysm of the ascending aorta presenting with pulmonary stenosis.
The symptoms and signs of aneurysms of the thoracic aorta are due mainly to compression of surrounding mediastinal structures and depend on the size and location of the aneurysm. Compression of the trachea, bronchi, oesophagus, recurrent laryngeal nerve, bone, and superior vena cava is common, but pressure on the pulmonary artery has not been described in spite of its intimate relation to the a...
متن کاملThe surgical treatment of acquired aneurysm of the thoracic aorta
The surgical treatment of an aneurysm of the abdominal aorta is a well-established procedure with fairly clear-cut indications and limitations. Treatment of an aneurysm of the thoracic aorta, on the other hand, is a more hazardous procedure that requires partial or total cardiac bypass with hypothermia, either moderate or profound, with or without local cooling of the heart. The reason for this...
