摘　　要：目的　探讨肝血管瘤的螺旋CT新征象及其发生原因。方法　报道 3 6例肝血管瘤共 5 1个瘤灶 ,均作螺旋CT多期扫描。结果　在动脉期 :① 3 6例中 8例出现瘤周肝实质高灌注区 14处 ;② 9例肝血管瘤中出现 19支门脉早显。三期螺旋CT扫描中出现瘤周肝实质高灌注区和早显门脉分支的密度变化均有非常显著差异 (P <0 .0 1) ;这两个征象的发生率呈正相关 (r=0 .80 16,P <0 .0 5 )。结论　肝血管瘤这两个新征象的病理学基础可能是因瘤体内存在着不同水平的动门静脉瘘和分流等所致。Objective To study the new signs of spiral CT (SCT) in the hepatic hemangioma (HH) and its causes. Methods Thirty six patients with 51 lesions underwent examination with the multi phases of SCT scanning (arterial phase AP, portal venous phase PVP, and delayed phase DP). Results In the arteral phase:① 8 cases of the 36 patients appeared as the hyper infusion area (HIA) ( n =14 focuses), ② 9 cases of 36 patients presented the early displayed of the portal venous branches (EDPVB) ( n =19 branches); these changes of enhancement of HIA and EDPVB among the three phases had statistitical difference ( P <0.01), respectively. The occurring rate of two signs between HIA and EDPVB had a positive correlative ( r =0.8016, P <0.05) in AP. Conclusion The pathologic foundations of the two new SCT signs may be caused by the arterio portal venous fistula (AV F)/arterio portal venous shunting (AV S) at different level in the HH. [
