Iatrogenic aortic dissection of the descending aorta after percutaneous coronary intervention

Iatrogenic Rupture of The Descending Aorta After Coronary Angiography : A Case Report

“…Some factors favor the occurrence of dissection or rupture of aorta during coronary angiography or angioplasty, such as older age, extensive atherosclerosis, high blood pressure, presence of aorta aneurysm, also patients undergoing transthoracic aortic valve replacement etc. [7] Our patient had probably aneurysm or dissection of descending www.cmhrj.com aorta, but not investigated before coronary angiography, so it could be aneurysm complicated by dissection and rupture, or chronic limited aortic dissection which was aggravated by catheter manipulation, with extension of dissection and rupture. CT angiography showed extensive dissection of descending aorta with contained rupture in the left lung, which allowed a temporary hemodynamic stability of the patient and his survival for a few days.…”

“…[6] Dissection with rupture of descending aorta was also reported during coronary angiography in one patient with transthoracic aortic valve replacement. [7] Iatrogenic aortic dissection is related to catheter manipulation and trauma of an already fragile aortic wall; rupture may be related to catheter penetration in the false lumen, and perforation of the aortic wall. Some factors favor the occurrence of dissection or rupture of aorta during coronary angiography or angioplasty, such as older age, extensive atherosclerosis, high blood pressure, presence of aorta aneurysm, also patients undergoing transthoracic aortic valve replacement etc.…”
