We report on 2 patients with hematologic diseases (1 follicular lymphoma and 1 myeloproliferative syndrome) and splenomegaly who had partial intrasplenic portosystemic shunting demonstrated by color Doppler sonography. Intrasplenic venous blood flow was in the normal direction at the hilum of the spleen but in a reversed direction at the periphery of the spleen. This type of reversed intrasplenic flow pattern results in portosystemic shunting and might be detected more frequently when careful color Doppler mapping of the entire splenic parenchyma is performed in patients with portal hypertension. The clinical significance of this phenomenon, however, is still unclear.
我们报告了2例患有血液系统疾病（1例滤泡性淋巴瘤和1例骨髓增殖综合征）并伴有脾肿大的患者，彩色多普勒超声显示其存在部分脾内门体分流。脾内静脉血流在脾门处方向正常，但在脾周边呈反向。这种脾内血流反向模式导致门体分流，并且在对门静脉高压患者进行整个脾实质的仔细彩色多普勒成像检查时，可能会更频繁地检测到。然而，这种现象的临床意义仍不明确。
