Two cases of portosystemic encephalopathy caused by an inferior mesenteric vein (IMV)-internal iliac vein shunt and an IMV-renal vein shunt are presented. IMV and systemic varicosity consisted of a first functional segment, a stagnant segment, and a second functional segment. Both patients underwent balloon occlusion retrograde transvenous obliteration (BRTO), using a microcatheter, to occlude the stagnant segment selectively. Although transient portal vein thrombosis was observed in case 1 and aggravation of esophageal varices was observed in case 2, these complications were tolerable. Following BRTO, the portosystemic encephalopathy in both cases resolved, and serum ammonia levels, although elevated, remained within the normal range.
现报告两例肠系膜下静脉（IMV）-髂内静脉分流和 IMV-肾静脉分流引起的门体系统脑病。IMV 和系统静脉曲张由第一功能段、停滞段和第二功能段组成。两名患者均采用微导管行球囊闭塞逆行经静脉闭塞术（BRTO），选择性闭塞停滞段。虽然 1 例患者出现短暂性门静脉血栓形成，2 例患者食管静脉曲张加重，但这些并发症是可以耐受的。BRTO 后，两例患者的门体系统脑病均得到缓解，血清氨水平虽然升高，但仍在正常范围内。
