The Influencing Factors and Prognostic Evaluation in the Treatment Decisions for Acute and Subacute Nondissection-Related Superior Mesenteric Artery Thromboembolism.

Background: The unclarified treatment strategy for acute and subacute ndSMA-TE limits the therapeutic efficacy and worsens the prognosis. This study aimed to determine the predictive factors impacting the treatment strategy for acute and subacute ndSMA-TE.

Method: A database of 116 patients with nonchronic ndSMA-TE admitted between January 2001 and December 2021 was retrospectively analyzed. Univariate/multivariate logistic regression and the predictive models constructed by stepwise backward regression were used to explore the influencing factors of the treatment decisions and the risk factors for failed conservative treatment. The EuroQol-5 Dimension questionnaire was used to evaluate the long-term quality of life.

Results: Only the white blood cell (WBC) levels were significantly different between the conservative group and the surgical group (P = 0.013 < 0 .05, odds ratio (OR) = 1.153, 95% confidence interval (CI) [1.038, 1.306]). The WBC levels (P < 0.001, OR = 1.169, 95% CI [1.080, 1.286]) and heart diseases (except atrial fibrillation) (P = 0.011 < 0 .05, OR = 5.116, 95% CI [1.541, 20.452]) were included in the predictive model of the treatment decision. The hemoglobin levels (P = 0.005 < 0 .05, OR = 1.095, 95% CI [1.040, 1.187]) and no flatus or stool (P = 0.007 < 0 .05, OR = 0.031, 95% CI [0.002, 0.296]) were significant risk factors for the conservative treatment outcome. The EuroQol-5 Dimension evaluation demonstrated a fairly high long-term quality of life in both treatment strategies.

Conclusions: Elevated WBC levels, decreased hemoglobin levels, and no flatus or stool can be used as predictive indicators for the surgical treatment of nonchronic ndSMA-TE to avoid a misdiagnosis and an inappropriate treatment.
