Abstract

Background: Acute mesenteric ischemia (AMI) is a life-threatening surgical emergency with a poor prognosis. This study assessed the association of diffuse reduction of spleen density (DROSD) with postoperative complications and identified risk factors for adverse outcomes in AMI patients after surgery.

Methods: Patients who were diagnosed with AMI and underwent surgical operations between April 2006 and July 2021 were enrolled. Spleen density was assessed using preoperative non-enhanced computed tomography. The lowest quartile of spleen density in all patients was regarded as the cutoff value for DROSD. Univariate and multivariate analyses were performed to determine the risk factors related to postoperative outcomes after surgery.

Results: According to the diagnostic cutoff, patients with a spleen density ≤49.07 HU were defined as DROSD. In a cohort of 97 patients, 34.0% developed complications within 30 days of surgery. The multivariate analysis illustrated that DROSD was an independent risk factor for prognostic outcomes in AMI patients after surgery.

Conclusion: Patients with low spleen density were prone to postoperative complications. As an imaging method, preoperative assessment of spleen density is a novel predictor that can be used clinically to identify high-risk AMI patients with poor prognosis.

脾脏密度在预测急性肠系膜缺血患者术后并发症中的作用

背景：急性肠系膜缺血（AMI）是一种危及生命的外科急症，预后较差。本研究评估了脾脏密度弥漫性降低（DROSD）与术后并发症的关系，并确定了AMI患者术后不良预后的风险因素：方法：研究对象为 2006 年 4 月至 2021 年 7 月期间确诊为 AMI 并接受外科手术的患者。使用术前非增强计算机断层扫描评估脾脏密度。所有患者脾脏密度的最低四分位数被视为 DROSD 的临界值。通过单变量和多变量分析确定与术后结果相关的风险因素：根据诊断临界值，脾脏密度≤49.07 HU的患者被定义为DROSD。在一组 97 例患者中，34.0% 的患者在术后 30 天内出现并发症。多变量分析表明，DROSD 是影响 AMI 患者术后预后的独立风险因素：结论：脾脏密度低的患者容易出现术后并发症。作为一种影像学方法，术前评估脾脏密度是一种新的预测指标，临床上可用于识别预后不良的高危 AMI 患者。
