To determine the normal dimensions of spleen by ultrasonography in our environment exposed to endemic tropical infection and infestation.
A prospective study of normal spleen ultrasound-based measurements in 200 Nigerian adults at the University of Benin Teaching Hospital Benin, Nigeria.
There were 91 males and 109 females; their age ranged between 20 and 60 years. For the males the mean age was 32.4 years (± 9.2 SD), mean height was 175.0 cm (±7.3 SD), mean weight was 72.5 kg (±10.1 SD), and mean body mass index was 23.6 (±2.8 SD) and the females the mean age was 29.7 years (±9.0 SD) mean height was 164.6 cm (±5.8 SD), mean weight 64.1 kg (±12.9 SD), and mean BMI was 24.9 (±1.4 SD). For the males the mean splenic length, width, depth, and volume were 11.1 cm (±0.9 SD), 4.4 cm (±0.5 SD), 7.8 cm (±0.6 SD), and 202.7 cm(3) (±49.4 SD), respectively. For the females the corresponding values of splenic length, width, depth, and volume were 10.1 cm (±0.7 SD), 4.0 cm (±0.4 SD), 7.1 cm (±0.5 SD), and 153.7 cm(3) (±33.2 SD), respectively.
Comparison between mean splenic dimension parameters for males and females (from unpaired t-test determination) showed a statistically significant difference (P<0.001 for splenic length, width, depth, and volume). There was also statistically significant increasing value correlation between subjects' weight and height (in favor of height) when compared to spleen length, width, depth, and volume. The other parameters show no significant correlation in both female and male. In particular there was also no statistically significant correlation of splenic measurements with age in either sex. This is similar to what was noted in other centers.
在我们所处的地方性热带感染和寄生虫感染环境中，通过超声检查确定脾脏的正常尺寸。
在尼日利亚贝宁大学教学医院对200名尼日利亚成年人进行基于超声的正常脾脏测量的前瞻性研究。
有91名男性和109名女性；他们的年龄在20至60岁之间。男性的平均年龄为32.4岁（标准差±9.2），平均身高为175.0厘米（标准差±7.3），平均体重为72.5千克（标准差±10.1），平均体重指数为23.6（标准差±2.8）；女性的平均年龄为29.7岁（标准差±9.0），平均身高为164.6厘米（标准差±5.8），平均体重为64.1千克（标准差±12.9），平均体重指数为24.9（标准差±1.4）。男性脾脏的平均长度、宽度、深度和体积分别为11.1厘米（标准差±0.9）、4.4厘米（标准差±0.5）、7.8厘米（标准差±0.6）和202.7立方厘米（标准差±49.4）。女性脾脏的长度、宽度、深度和体积的相应值分别为10.1厘米（标准差±0.7）、4.0厘米（标准差±0.4）、7.1厘米（标准差±0.5）和153.7立方厘米（标准差±33.2）。
男性和女性脾脏尺寸参数平均值之间的比较（通过非配对t检验确定）显示出统计学上的显著差异（脾脏长度、宽度、深度和体积的P<0.001）。与脾脏长度、宽度、深度和体积相比，受试者的体重与身高之间也存在统计学上显著的增加值相关性（有利于身高）。其他参数在女性和男性中均无显著相关性。特别是，脾脏测量值与任何性别的年龄均无统计学上的显著相关性。这与其他中心的情况类似。
