“…However, AD involving the aortic arch while sparing the ascending aorta is not addressed in these 2 classifications. Pasic and colleagues 6 defined a term for non-A non-B dissections in which an intimal tear was localized in the aortic arch in 1999, but this unique case of non-A non-B AD rarely occurs. As such, the best therapeutic option for such patients remains controversial.…”

Objective: This study reports the early outcomes of patients with acute non-A non-B aortic dissection that involved the aortic arch but not the ascending aorta.Methods: From January 2013 to December 2018, 825 patients presented with aortic dissection. Of these, 28 patients with non-A non-B dissection (classified as dissection extending into the aortic arch with entry between the left common carotid artery and the left subclavian arteries) underwent a novel hybrid surgery. Self modified stent-grafts (Micropart Corp, Shanghai, China) were implanted via median sternotomy. Clinical presentation, postoperative data, and early outcomes were recorded.Results: All patients underwent an emergency operation. There were no in-hospital mortalities, reexplorations for hemorrhage, reports of paraplegia, cerebral infarctions, endoleaks, or left subclavian artery occlusions. No blood products were required during or after the operations. During the early follow-up at 39.12 AE 15.04 months (6.0-74.0 months), 1 patient was lost to follow-up, and 1 patient died suddenly. Computed tomography angiography showed false lumen patency persisted in the aortic arch and descending aorta without any symptoms. The 6-month computed tomography angiography showed significantly smaller distal aortic arch diameters (31.94 AE 6.95 mm) and descending aorta diameters (34.84 AE 4.15 mm) than measured preoperatively (36.76 AE 4.15 mm and 37.31 AE 4.7 mm, respectively). No paraplegia, cerebral infarction, upper limb ischemia, or left subclavian artery ischemia events were reported.Conclusions: Our inclusion aortic arch technique is a safe, effective, and simple treatment for non-A non-B aortic dissections that can avoid endoleaks, requires no blood products, and has satisfactory early outcomes.
