This is case of removing a dislocated pushable coil from the common hepatic artery (CHA) as a possible complication of using pushable coils in the embolization of an upper gastrointestinal bleeding (UGIB) from the gastroduodenal artery (GDA) by using a pRESET stent retriever (Phenox, Bochum, Germany) which is utilized mainly for treatment of endovascular stroke.
An 88-year-old female patient was referred to our hospital to get an emergency embolization of the GDA causing an UGIB with a relevant drop of the hemoglobin level. During the routine embolization of the GDA using pushable coils, a complete dislocation of the last coil into the CHA took place leading to a relevant slowing down of the arterial blood flow to the liver. A decision was thereby made to remove the dislocated coil to avoid further possible complications which was successfully achieved.
Various stent retrievers have been proven to be effective in removing dislocated coils during intracerebral coiling of different pathologies. This case report is to our knowledge the first case report proving the high efficacy and safety of using yet another stent retriever, namely a pRESET stent retriever in removing a fully dislocated coil in the abdominal vessels, namely in this case the CHA.
本文报道了一例从肝总动脉（CHA）取出移位可推送线圈的病例，这可能是在使用pRESET支架取栓器（德国波鸿市菲尼克斯公司）栓塞胃十二指肠动脉（GDA）所致上消化道出血（UGIB）时使用可推送线圈的并发症，该取栓器主要用于治疗血管内中风。
一名88岁女性患者因GDA导致UGIB且血红蛋白水平显著下降，被转诊至我院接受紧急栓塞治疗。在使用可推送线圈对GDA进行常规栓塞过程中，最后一个线圈完全移位至CHA，导致肝脏动脉血流明显减慢。因此决定取出移位的线圈以避免进一步可能出现的并发症，最终成功实现。
各种支架取栓器已被证明在不同病变的脑内线圈置入过程中有效取出移位线圈。据我们所知，本病例报告是首例证明使用另一种支架取栓器，即pRESET支架取栓器在腹部血管（本例为CHA）中取出完全移位线圈的高效性和安全性的病例报告。
