Purpose:
To retrospectively investigate factors associated with mesenteric artery remodeling after conservative management of isolated mesenteric artery dissection (IMAD) (dissection of the mesenteric arteries in the absence of aortic dissection or other known causes).
Materials And Methods:
A total of 107 patients diagnosed with IMAD between February 2010 and October 2018 were identified. Eighteen patients were excluded because they underwent stent placement (n = 11) or were lost to follow-up (n = 7). A total of 89 patients who underwent conservative management were therefore included in the study. Cox regression analysis was performed to identify factors associated with mesenteric artery remodeling.
Results:
During 15.9 ± 10.9 months of follow-up, complete remodeling of the mesenteric artery was achieved in 66 patients (74.2%), and partial remodeling was achieved in 23 patients (25.8%). Of the 66 patients with complete remodeling, 6 (9.1%) had type IIa IMAD (visible false lumen, no visible re-entry site), and 60 (90.9%) had type IIb IMAD (thrombosed false lumen). The mean interval between IMAD diagnosis and complete remodeling was 14.4 ± 5.4 months for all patients. The mean intervals for patients with type IIa IMAD were 20.0 ± 6.2 months and 13.9 ± 5.1 months for patients with type IIb IMAD (P = .015). Mesenteric artery remodeling was significantly associated with the presence of symptoms (odds ratio, 10.800; 95% confidence interval, 1.961-59.470; P = .006).
Conclusions:
Complete remodeling of the mesenteric artery in patients with IMAD treated with conservative management is common, and the presence of symptoms is associated with complete remodeling.
