Abstract：
Subclavian artery injuries are sporadic, and the most common aetiology is trauma. Self-injury of the vessel in those misusing intravenous drugs is a rare complication, as most reports describe injury to the femoral artery. Thus, erosion and potential rupture of the arterial wall is possible due infection and phlegmon or abscess formation. We present a case of a young, female, hemodynamically unstable intravenous drug user admitted to the emergency department with a life-threatening, purulent haemorrhagic mass located at her right lateral cervical region. The patient admitted an inadvertent arterial puncture 10 days prior and an effort to self-manage the bleeding with the application of self-pressure and antibiotics. Computed tomography arteriogram of the neck revealed a gigantic, multicompartment, thick-walled collection with hyperdense fluid in her right supraclavicular region while active extravasation derived from the right subclavian artery was evident in late arterial phase. The patient was treated with endovascular graft stenting, despite the given presence of infection, as a salvage operation due to time limitation in open surgical repair.
摘要：
锁骨下动脉损伤是偶发性的,最常见的病因是外伤.在那些滥用静脉药物中，血管的自我损伤是一种罕见的并发症，大多数报道都描述了股动脉的损伤。因此，由于感染和痰或脓肿的形成，动脉壁的侵蚀和潜在的破裂是可能的。我们提出了一个年轻人的案例，女性,血液动力学不稳定的静脉吸毒者因危及生命而被送往急诊科，位于她的右外侧宫颈区域的化脓性出血性肿块。患者在10天前接受了无意的动脉穿刺，并努力通过应用自我压力和抗生素来自我管理出血。颈部的计算机断层扫描动脉造影显示出巨大的，多隔间,在她的右锁骨上区域有厚壁聚集，高密度液体，而在动脉晚期明显来自右锁骨下动脉的活动性外渗。患者接受了血管内支架植入治疗，尽管存在感染，由于开放手术修复的时间限制，作为抢救手术。
