A quantitative study of white pulp arterial vessels has been carried out in congestive splenomegaly with hypersplenism. Arteries and arterioles with periarterial lymphatic sheath (PALS) in abnormal spleens show an absolute volume and total length higher than in controls. Moreover, they present a luminal diameter significantly lower than normal. These findings demonstrate an increase of the white pulp arterial bed in congestive splenomegaly. Thus, the arteries with PALS participate in the complex vascular rearrangement which supports the blood hyperflow in congestive splenomegaly.
对伴有脾功能亢进的充血性脾肿大患者的白髓动脉血管进行了定量研究。异常脾脏中带有动脉周围淋巴鞘（PALS）的动脉和小动脉，其绝对体积和总长度均高于对照组。此外，它们的管腔直径明显低于正常水平。这些发现表明充血性脾肿大时白髓动脉床增加。因此，带有PALS的动脉参与了支持充血性脾肿大时血流增加的复杂血管重排过程。
