Acquired Aortic Coarctation Due to Posttuberculotic Gibbous Formation

Abstract

This is a report on a rare case of acquired stenosis of the descending thoracic aorta resulting from an extreme posttuberculotic gibbous formation. The unusual anatomical relationship precluded conventional alleviation of the stenosis which was bridged ultimately with a graft producing a satisfactory functional result.

Percutaneous stenting of acquired thoracic aorta occlusive disease

“…There are case reports of different etiologies giving rise to this manifestation: Takayasu's disease [9], posttraumatic [10], tuberculotic gumma [11], postirradiation [12], aortic sarcoma [13], calcified thrombus and atherosclerosis [1][2][3][4][5][6][7][8]. Although atherosclerosis of the descending aorta causing obstructive aortoiliac disease is relatively common, significant symptomatic atherosclerotic stenosis involving the thoracic aorta is rare.…”

Live/Real Time Three‐Dimensional Transthoracic Echocardiography in the Evaluation of Post Traumatic Acquired Thoracic Aortic Coarctation

“…It can occur at any point from the arch to the bifurcation of the iliac arteries but is most commonly found distal to the origin of the left subclavian artery. Acquired coarctation on the other hand is a noncongenital obstructive lesion of the aorta that could result from different etiologies ranging from aortic atherosclerosis, 1 calcified thrombus, 2 aortic sarcoma, 3 post tuberculosis, 4 post irradiation, 5 or post traumatic 6 . Post traumatic acquired aortic coarctation frequently occurs due to stent graft collapse with proximal protrusion of the graft into the arch 7 .…”
