Lumboperitoneal (LP) shunt placement is a good option for treating elderly patients with communicating normal pressure hydrocephalus (NPH) who are also on antiplatelet therapy following endovascular treatment of unruptured bilateral internal carotid artery aneurysms. Here, in an 80-year-old male with an LP shunt, the catheter was "pinched" between adjacent spinous processes, resulting in laceration of the catheter and intrathecal catheter migration.
An 80-year-old male was treated with a LP shunt for NPH 1 year after undergoing endovascular treatment of unruptured bilateral internal carotid artery aneurysms. The lumbar catheter was placed at the L2-3 level. Six months later, when he clinically deteriorated, the follow-up computed tomography showed recurrent ventricular enlargement. Further, studies additionally confirmed intrathecal migration of the lumbar catheter, warranting secondary ventriculoperitoneal shunt placement.
Patients with LP shunts may develop lumbar catheter lacerations secondary to a "pinching" effect from adjacent spinous processes, resulting in intrathecal catheter migration.
腰大池-腹腔(LP)分流术是治疗老年交通性正常压力脑积水(NPH)患者的一种良好选择,这些患者在未破裂双侧颈内动脉动脉瘤血管内治疗后还接受抗血小板治疗。在此,一名80岁男性患者置入了LP分流管,导管被相邻棘突“挤压”,导致导管撕裂和鞘内导管移位。
一名80岁男性在未破裂双侧颈内动脉动脉瘤血管内治疗1年后因NPH接受LP分流术。腰段导管置于L2-3水平。6个月后,当他临床症状恶化时,随访计算机断层扫描显示脑室再次扩大。此外,研究进一步证实腰段导管发生鞘内移位,因此需要再次行脑室-腹腔分流术。
LP分流术患者可能因相邻棘突的“挤压”效应导致腰段导管撕裂,从而引起鞘内导管移位。
