Abstract

PURPOSE

There are many variations of the iliac vein, and it is aimed to evaluate these variations using multidetector computed tomography (MDCT).

METHODS

Pelvic MDCT images of 1071 adult patients (576 males; 495 females; age range 18-94 years; mean age 50.3 years) were retrospectively evaluated. Reconstruction images of the pelvic region in sagittal and coronal planes were evaluated. Except for the usual iliac venous anatomy, all types of iliac vein connections were defined as "iliac venous variation".

RESULTS

Of the 1071 patients, 84.2% were considered as type 1 (usual). Different variations were observed in 15.8% of the patients, of whom, 63.9% of were male and 36.1% female, and this gender difference was statistically significant (p < 0.05). The rates of variations detected in the study were type 2 (49.7%), type 3 (29%), type 4 (4.7%), type 5 (6.5%), type 6 (4.8%), type 7 (1.8%) and type 8 (3.6%) respectively. New subtypes that we named as type 3c, type 6f, type 6 × and type 7b were first determined in our study.

CONCLUSION

Knowledge and evaluation of iliac venous variations before pelvic surgery or interventional procedures is of importance in preventing possible complications.

摘要

目的

髂静脉有多种变异，本研究旨在使用多排螺旋 CT（MDCT）评估这些变异。

方法

回顾性分析了 1071 例成年患者（576 例男性，495 例女性；年龄 18-94 岁；平均年龄 50.3 岁）的盆腔 MDCT 图像。评估了矢状面和冠状面盆腔重建图像。除了通常的髂静脉解剖结构外，所有类型的髂静脉连接均定义为“髂静脉变异”。

结果

在 1071 例患者中，84.2%被认为是 1 型（常见型）。15.8%的患者存在不同类型的变异，其中 63.9%为男性，36.1%为女性，这种性别差异具有统计学意义（p<0.05）。本研究中检测到的变异类型发生率分别为 2 型（49.7%）、3 型（29%）、4 型（4.7%）、5 型（6.5%）、6 型（4.8%）、7 型（1.8%）和 8 型（3.6%）。在本研究中首次确定了新的亚型，分别命名为 3c 型、6f 型、6×型和 7b 型。
