Although various types of portosystemic shunts with portal hypertension have been widely reported, a collateral circulation near the pancreas head is rare. The authors report a case of a rare portosystemic shunt surrounding the pancreatic head, which was diagnosed by dynamic liver scintigraphy using Ikoma's scintigraphic criteria for the presence of portosystemic shunts. According to these criteria, abnormal accumulation of radioactivity at various abdominal sites (not identified on static images after the dynamic study) on 6 or more continuous frames of 5-second intervals (i.e., for 30 seconds or more after the arterial phase) indicates the presence of a portosystemic shunt. If liver scintigraphy is performed on a patient with portal hypertension, the dynamic study is valuable in the detection and diagnosis of a portosystemic shunt.
尽管各种类型伴有门静脉高压的门体分流已被广泛报道，但胰头附近的侧支循环却很罕见。作者报告了一例罕见的围绕胰头的门体分流病例，该病例通过使用生驹门体分流存在的闪烁扫描标准的动态肝脏闪烁扫描得以诊断。根据这些标准，在5秒间隔的6个或更多连续帧（即动脉期后30秒或更长时间）上，腹部各个部位出现放射性异常积聚（动态研究后静态图像上未发现）表明存在门体分流。如果对门静脉高压患者进行肝脏闪烁扫描，动态研究对于门体分流的检测和诊断很有价值。
