Portal hypertension can develop from any disorder that obstructs portal blood flow and may cause ascites in young dogs. Anomalous hepatic arteriovenous (AV) connections are rare but should be suspected in any young dog with portal hypertension or ascites. All previous reports of dogs with hepatic AV fistulae have documented macroscopic connections between the arterial and venous systems. Identical clinical signs and histopathologic findings can develop in dogs in which a macroscopic hepatic AV connection cannot be detected. Microscopic AV connections may be responsible for clinical signs in these dogs.
门静脉高压可由任何阻塞门静脉血流的疾病引起，并且可能在幼犬中导致腹水。肝动静脉（AV）异常连接很少见，但在任何患有门静脉高压或腹水的幼犬中都应怀疑。之前所有关于患有肝动静脉瘘犬的报告都记录了动脉和静脉系统之间的宏观连接。在无法检测到宏观肝动静脉连接的犬中也可出现相同的临床症状和组织病理学发现。微观动静脉连接可能是这些犬临床症状的原因。
