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.

使用脑内支架取回器在肝总动脉中脱位的可推动线圈进行血管内取回

这种情况是从肝总动脉（CHA）上移除脱位的可推动线圈，这是通过使用pRESET支架取回器从胃十二指肠动脉（GDA）上消化道出血（UGIB）栓塞中使用可推动线圈的可能并发症（ Phenox，德国波鸿（Bhenum），主要用于治疗血管内中风。一名88岁的女性患者被转诊到我院接受GDA的紧急栓塞，导致UGIB并伴有血红蛋白水平的下降。在使用可推动线圈对GDA进行常规栓塞的过程中，最后一个线圈完全脱位到CHA中，导致进入肝脏的动脉血流明显减慢。从而决定移除错位的线圈，以避免成功实现的进一步可能的并发症。事实证明，各种支架检索器可有效清除不同病状的脑内盘绕过程中脱位的盘绕。就我们所知，该病例报告证明了使用另一种支架取回器（即pRESET支架取回器）去除腹部血管中完全脱位的线圈（在这种情况下为CHA）具有很高的效力和安全性。
