Type a Aortic Dissection Developing during Endovascular Repair of an Acute Type B Dissection

Abstract

Endovascular repair of acute type B dissection is technically feasible, but longer experience will help prevent technical complications.

Serious complications following endovascular thoracic aortic stent-graft repair for type B dissection

“…Our results are similar to the Stanford group. Acute retrograde type A dissection after endovascular stent-graft repair is a rare complication that has been described in conjunction with the procedure [16,17]. However, as seen in five of our patients, one must be aware that this complication can occur not only during the procedure but even days, weeks, or months following stentgraft implantation, a fact that seems to be under-reported.…”

“…Aneurysm development, aortic rupture, stroke, paraplegia, bowel infarction, limb ischemia, access-related complications, and endoleaks have been described [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Retrograde type A dissection was recognized by several study groups; however, it is still an unexpected complication following endovascular stent-graft repair [15][16][17][18].…”

“…Several study groups have documented the feasibility of endovascular stent-graft repair in acute or elective type B dissection, however not without significant morbidity [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Acute or delayed retrograde type A dissection (6, 8%) [15][16][17][18], stroke (3%) [1], paraplegia (2%) [1], access-related complications (27%) [10], endoleaks (4%) [1], bowel infarction, limb ischemia, or wound infection have been described [1][2][3][4][5][6][7][8][9][10].…”

Retrograde type A dissection after endovascular stenting of the descending thoracic aorta. Is the risk real?☆

“…The delay between stent-graft implantation and identification of a complicating intimal tear or dissection can vary from immediately postoperative deployment of stent-graft to 2 months after the procedure [5,6]. In a report by Won et al [7], retrograde type A dissection was diagnosed 1-5 months post-procedure (mean 3.2 months).…”

Postendovascular thoracic aortic repair subclavian steal syndrome revealed by severe headache

“…Also the headache is reported as one of the symptoms of an aortic dissection type A which had developed during endovascular repair of acute type B dissection [14].…”
