Acquired Aortic Coarctation Due to Posttuberculotic Gibbous Formation
The Thoracic and Cardiovascular Surgeon (Impact Factor: 0.98). 03/1984; 32(1):54-6. DOI: 10.1055/s-2007-1023345
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.

ABSTRACT: An extremely rare manifestation of atherosclerosis is described. Two women, aged 57 and 55, presented with upper extremity hypertension and diminished femoral pulses. Plain radiography and total angiographic visualization of the aorta demonstrated focal highly obstructing intraluminal masses containing heavy flocculent calcification in the upper descending thoracic (case 1) and the thoracoabdominal aorta (case 2) producing a significant pressure gradient. The acquired coarctation due to calcified thrombus was relieved by resection and graft replacement in one and placement of a thoracoabdominal bypass graft in the second patient.
Article: Acquired coarctation of the aorta[Show abstract] [Hide abstract]
ABSTRACT: Coarctation of the aorta is usually caused by a congenital narrowing of the aorta. This report describes two children who developed hypertension secondary to an acquired coarctation of the aorta. In one patient the coarctation was temporally related to umbilical artery catheterization and was associated with thrombosis and aneurysmal dilatation of the aorta. In the second patient, the coarctation occurred after surgical aortotomy during the removal of an intrathoracic neuroblastoma. Patients who have interventional damage to the aorta should be periodically examined for the appearance of a coarctation. Although an acquired coarctation of the aorta is an infrequent complication of invasive or surgical procedures, it should be identified since it represents a remediable cause of hypertension in children.
