Abstract

Introduction: The spleen is a lymphatic organ that manages immune surveillance of the blood, produces blood cells, and helps filter the blood, remove old blood cells, and fight infection. The normal splenic weight is approximately 65-265 g. This study evaluated spleen volume and segmental volume.

Methods: 121 patients who underwent enhanced CT at our center were analyzed. The spleen was divided into upper, middle, and lower segments according to arterial flow area, and the volume of each segment was measured. Patients were classified into two groups as those with and without liver cirrhosis, and differences in the distribution of the segments in these groups was evaluated.

Results: The mean upper, middle, and lower spleen segmental volume ratios were 35.4%, 37.0%, and 27.6%, respectively. In the liver cirrhosis group, the segmental splenic volume ratios for the upper, middle, and lower segments were 34.5%, 38.5%, and 28.0%, respectively, indicating that these ratios remain similar regardless of liver cirrhosis status.

Conclusion: The present findings on segmental spleen volume are useful for estimating infarction volume in cases of partial splenic arterial embolization.

部分脾动脉栓塞术的脾动脉血流和脾脏节段体积分布。

引言脾脏是一个淋巴器官，负责管理血液的免疫监视、制造血细胞，并帮助过滤血液、清除老旧血细胞和抗感染。正常脾脏重量约为 65-265 克。本研究对脾脏体积和节段体积进行了评估。根据动脉血流面积将脾脏分为上段、中段和下段，并测量各段的体积。将患者分为有肝硬化和无肝硬化两组，并评估这两组患者脾脏节段分布的差异：结果：平均上、中、下脾段体积比分别为 35.4%、37.0% 和 27.6%。在肝硬化组中，上、中、下脾段体积比分别为 34.5%、38.5% 和 28.0%，这表明无论肝硬化状况如何，这些比率都是相似的：结论：目前关于脾脏节段体积的研究结果有助于估计部分脾动脉栓塞病例的梗死体积。

期刊介绍： The international effort to understand, treat and control disease involve clinicians and researchers from many medical and biological science disciplines. The Journal of Nippon Medical School (JNMS) is the official journal of the Medical Association of Nippon Medical School and is dedicated to furthering international exchange of medical science experience and opinion. It provides an international forum for researchers in the fields of bascic and clinical medicine to introduce, discuss and exchange thier novel achievements in biomedical science and a platform for the worldwide dissemination and steering of biomedical knowledge for the benefit of human health and welfare. Properly reasoned discussions disciplined by appropriate references to existing bodies of knowledge or aimed at motivating the creation of such knowledge is the aim of the journal.
