Abstract

Objective: Different methods are applied for aortic arch treatment in Stanford A aortic dissection, but it’s lack of long term results of false lumen status of different methods. This retrospectively study will analyze the effect of the false lumen status of different methods in a single center.

Methods: From January 2010 to December 2015, 139 cases(of which 108 malesand 31 females) were finally selected after excluding the cases who died during hospitalization, whose perioperative clinical data were incomplete, follow-up information were incomplete, and DeBakey type II aortic dissection and the cases with descending aorta dilatation.  The average age was 50.3 ± 11.6 years (22-76 years).  According to the methods for aortic arch and descending aorta, 139 cases were divided into 5 groups: 24 cases in AR((including ascending aorta replacement, ascending aorta + hemi-arch replacement and ascending aorta + island-arch replacement), 9 cases in AR+SET(including ascending aorta + hemi-arch replacement + stent elephant trunk and ascending aorta + island-arch replacement + stent elephant trunk), 42 cases in Arch+SET(ascending aorta + arch replacement + stent elephant trunk), 22 cases in AR+ TBS(ascending aorta + triple branched stent) and 42 cases in AR+FS(ascending aorta + arch fenestrated stent). Statistical analysis the size of true lemen and the status of false lumen among these five groups in the level of aortic arch, the distal end of stent, diaphragm, celiac artery, renal artery and iliac artery postoperatively.

Results: Different levels of descending aorta in each group have showed varying degrees of true lumen open and thrombosis of false lumen during follow-up period. Among them, cases with aortic arch treatment and stent implantation have showed higher ratio of thrombosis of false lumen.

Conclusions: Effects of different stents were similar, which all promoted the process of thrombosis of false lumen.
