Vascular injuries to hepatic arterial blood flow present a challenge in reconstruction. The location and extent of the injury dictate intraoperative decision making, with repair being performed expeditiously to preserve hepatic function. Formal arterial repair either primarily or with interposition or transposition grafts is indicated in the majority of patients. Special consideration should be made in patients with underlying liver disease and those undergoing biliary reconstructions. This latter group of patients is at high risk of complications following the injury secondary to bile duct ischemia.
A case of proper hepatic artery (PHA) transection repaired with gastroduodenal artery (GDA) transposition is presented with a relevant review of limited literature available on the subject.
During an elective pancreaticoduodenectomy the PHA was inadvertently transected just distal to the origin of the GDA. As the GDA had not been transected at this stage of the operation, it was available for transposition. This was performed, restoring arterial blood flow to the liver and the bile duct. The patient did well postoperatively with no evidence of biliary or pancreatic leak or hepatic dysfunction at both discharge and follow-up clinic visit.
Injuries to hepatic artery injury are uncommon in experienced hands. This case report is only the second instance of such injury requiring reconstruction in 434 cases of single operator experience pancreaticoduodenectomies. We present arterial transposition of GDA as a feasible method to ensure adequate arterial supply to the hepatobiliary system.
肝动脉血流的血管损伤在重建方面具有挑战性。损伤的位置和范围决定了术中的决策,需要迅速进行修复以保护肝功能。大多数患者需要进行一期动脉修复,或采用间置或转位移植血管修复。对于有潜在肝脏疾病的患者以及正在进行胆管重建的患者,应给予特别考虑。后一组患者在损伤后因胆管缺血而发生并发症的风险很高。
本文报告一例采用胃十二指肠动脉(GDA)转位修复肝固有动脉(PHA)横断的病例,并对该主题的有限文献进行相关综述。
在择期胰十二指肠切除术中,PHA在GDA起始部远端意外横断。由于在手术的这个阶段GDA未被横断,因此可用于转位。进行了转位操作,恢复了肝脏和胆管的动脉血流。患者术后恢复良好,出院时及随访门诊均无胆漏、胰漏或肝功能障碍的迹象。
在经验丰富的医生手中,肝动脉损伤并不常见。该病例报告是434例由单一术者完成的胰十二指肠切除术中,第二例需要进行此类损伤重建的病例。我们提出GDA动脉转位是确保肝胆系统充足动脉供应的一种可行方法。
