Several types of adjustable clamp have been widely utilized to gradually occlude the carotid artery for the treatment of various intracranial vascular lesions. A fairly large number of patients, many of whom have not been adequately followed, have these clamps still in place. The authors report two patients, initially treated with a Crutchfield clamp for an intracranial aneurysm, in whom carotid artery system revascularization occurred through the clamp many years later, leading to continued filling of the aneurysm. Recommendations are given on monitoring patients with Crutchfield clamps in order to minimize long-term complications.
几种类型的可调式夹钳已被广泛用于逐步夹闭颈动脉，以治疗各种颅内血管病变。相当多的患者（其中许多患者未得到充分随访）仍留有这些夹钳。作者报告了两名最初用Crutchfield夹钳治疗颅内动脉瘤的患者，多年后颈动脉系统通过该夹钳实现了血管重建，导致动脉瘤持续充盈。针对监测使用Crutchfield夹钳的患者给出了相关建议，以尽量减少长期并发症。
