The purpose of this study was to investigate whether focal fatty sparing (FFS) formation in the liver relates to aberrant blood flow.
Sixty-three FFSs of the liver in 52 patients were examined by color Doppler flow imaging and contrast-enhanced microvessel display sonography. The 63 FFSs included 16 FFSs in the porta hepatis, 14 FFSs around the gallbladder fossa, and 33 other FFSs. The control group included patients with a diagnosis of fatty liver but no FFSs or focal lesions near the porta hepatis.
Fourteen of 16 FFSs in the porta hepatis showed venous blood toward those areas that were differentiated from the portal and hepatic veins. Focal fatty sparings in the hilus hepatis correlated with aberrant veins, having a statistical significance compared with the control group (P < .0001). Seven of 14 FFSs around the gallbladder fossa contained blood vessels, 5 of them veins and the remaining 2 arteries. Two FFSs were located around hemangiomas. Three FFSs were located around maldeveloped vessels.
The blood supply to an FFS in the porta hepatis may be correlated with aberrant veins. Focal fatty sparings around the gallbladder fossa may be associated with aberrant blood flow.
本研究旨在探讨肝脏局灶性脂肪 sparing(FFS)的形成是否与异常血流有关。
对52例患者的63个肝脏FFS进行彩色多普勒血流成像和对比增强微血管造影超声检查。63个FFS包括肝门处16个FFS、胆囊窝周围14个FFS和其他33个FFS。对照组包括诊断为脂肪肝但肝门附近无FFS或局灶性病变的患者。
肝门处16个FFS中有14个显示有静脉血流朝向这些与门静脉和肝静脉不同的区域。肝门处的局灶性脂肪 sparing与异常静脉相关,与对照组相比具有统计学意义(P <.0001)。胆囊窝周围14个FFS中有7个含有血管,其中5个为静脉,其余2个为动脉。2个FFS位于血管瘤周围。3个FFS位于发育不良的血管周围。
肝门处FFS的血液供应可能与异常静脉有关。胆囊窝周围的局灶性脂肪 sparing可能与异常血流有关。
