To illustrate the sonographic and Doppler features of the different types of intrahepatic vascular shunts.
Patients presenting in our department with intrahepatic vascular shunts with healthy livers or with a variety of liver pathologies underwent color Doppler interrogation and spectral analysis.
Intrahepatic vascular shunts may involve all liver vessels. Arterioportal and arteriosystemic venous connections can be recognized in normal and cirrhotic livers, following trauma, within tumors, and within nontumoral arteriovenous malformations. Portosystemic intrahepatic venous shunts are categorized into 4 morphologic types. Systemic-to-systemic shunts are more often recognized in patients with chronic hepatic venous congestion or with Budd-Chiari syndrome. Portal-to-portal intrahepatic venous shunts are rare, with few cases described.
In general, all the liver vessels can be associated with formation of arterioportal, arteriosystemic, and portosystemic venous shunts and, rarely, systemic venous shunts and portal-to-portal communications. Sonography allows characterization of the different intrahepatic shunts.
阐述不同类型肝内血管分流的超声及多普勒特征。
我院收治的患有肝内血管分流且肝脏健康或伴有各种肝脏病变的患者接受了彩色多普勒检查及频谱分析。
肝内血管分流可能累及所有肝血管。在正常肝脏、肝硬化肝脏、创伤后、肿瘤内以及非肿瘤性动静脉畸形内均可识别动脉门静脉和动脉体静脉连接。肝内门体静脉分流可分为4种形态类型。体-体分流在慢性肝静脉淤血或布加综合征患者中更常被识别。肝内门静脉-门静脉分流罕见，仅有少数病例报道。
一般而言，所有肝血管均可形成动脉门静脉、动脉体静脉和门体静脉分流，很少形成体静脉分流和门静脉-门静脉交通。超声检查可对不同的肝内分流进行特征性描述。
