摘要
肝右动脉是供应肝右叶的终末动脉,解剖变异常见,且变异种类繁多,包括肝右动脉和肝左动脉分叉低、走行变异、迂曲畸形、胆囊动脉分支异常和起源变异。肝右动脉起源变异可分为异位肝右动脉和副肝右动脉两种情况,异位起源动脉包括肠系膜上动脉、腹腔干、腹主动脉、肝总动脉、胃十二指肠动脉、胃左动脉、脾动脉和右肾动脉。肝右动脉变异是肝胆胰脾外科手术不良事件和术后并发症的重要原因,术前对其有充分的认识和掌握,术中细致分离和妥善保护是手术安全的重要保障。
The right hepatic artery(RHA)is the terminal artery supplying the right hepatic lobe.There are many anatomic variations of RHA,including low RHA and left hepatic artery bifurcation,aberrant course,tortuosity,abnormal branches of cystic artery and origin variation.The origin variation of RHA is divided into replaced RHA and accessory RHA.The replaced artery origins include superior mesenteric artery,celiac trunk,aorta,common hepatic artery,gastroduodenal artery,left gastric artery,splenic artery and right renal artery.The variations of RHA are important causes of intraoperative adverse events and postoperative complications in hepatobiliary-pancreatic-splenic surgery.It is an important guarantee for the safety of operation to know and master these RHA variations well before operation,to separate it carefully and to protect it properly during operation.
