Simultaneous Stent-Graft Repair of Thoracic and Infrarenal Abdominal Aortic Aneurysms

Abstract

Simultaneous endovascular treatment of thoracic and infrarenal abdominal aortic aneurysms may represent a viable alternative for therapy in some patients.

Simultaneous Open and Endoluminal Repair of Ruptured Abdominal and Thoracic Aortic Aneurysms: Report of a Case

“…Cuypers et al 9 concluded that hemodynamic changes during stent-graft repair were not as severe as those that occurred during open surgery, and resulted in less myocardial stress. We also think that stent-graft repair is Wolf et al 10 and Meguid et al 11 described performing simultaneous stent-graft repair of concomitant TAA and AAA. We considered open and endovascular repair options for our patient, but the dual aneurysms and recent episode of myocardial infarction placed her at too high a risk for an open repair.…”

Endovascular repair for concomitant multilevel aortic disease☆

“…The estimated incidence of simultaneous thoracic and abdominal aortic disease is approximately 10-20% of the patients [1][2][3][4][5]. There is a very little data available for combined thoracic and abdominal aneurysm repair; historically simultaneous thoracic and abdominal aortic disease repair showed to be a challenging surgical procedure.…”

“…Abdominal aortic disease included atherosclerotic infrarenal (nZ3) and juxtarenal (nZ1) aortic aneurysms. Mean abdominal aortic aneurysm (AAA) diameter was 67G13 mm (range, [5][6][7][8]. Mean thoracic aortic lumen measured 33.5 mm (range 30-38 mm).…”

“…Endovascular treatment has been suggested as a viable alternative to treat both the diseased aortic areas; it could allow for a lower complication risk than for a procedure associated with open thoracotomy and aortic cross-clamping. However, few brief published data reported separate stent-grafts (SG) were used to repair isolated thoracic and abdominal aortic aneurysms during a single procedure [4][5][6]. Combined endovascular SG placement could effectively exclude both areas of aortic disease without the added morbidity of a thoracic incision or second operation.…”

Three Dimensional Active Contours for the Reconstruction of Abdominal Aortic Aneurysms

“…15,20,27,35 These could also be used to better diagnose the disease progression, assess the feasibility of an EVAR procedure, and design better stent-grafts. Although 2D deformable models (in image reconstruction) give a good approximation to the true shape, the resulting geometry may not be smooth (owing to a lack of proper interpolation of intensity between successive image slices) when lofted using CAD.…”
