Vascular access for hemodialysis is a key factor in every patient dependent on this treatment. Maintaining a central venous catheter can be a good choice when all the other options have been exhausted, but unwanted and rare complications may arise from longer catheter dwell time.
We describe a case of a 65-year-old woman undergoing hemodialysis treatment since 1986 after a bilateral nephrectomy due to complicated nephrolithiasis. Her last access, two Tesio® tunneled cuffed catheters implanted via the right internal jugular vein functioned correctly for 14 years without complications, and so, was not replaced in the meantime. She was referred to our hospital due to a rupture in a catheter lumen, which was corrected conservatively by creating a more proximal tunnel and excising the affected area. A few weeks later, a new rupture in the same lumen was identified, so the catheter was replaced with angiographic control. The catheter was frail, so upon its removal, the tip fractured and remained in the right ventricle, being swiftly removed by an endovascular without complications.
This case reports two rare complications associated with catheter handling and identifies a possible technique for conservative resolution of a lumen rupture.
血液透析的血管通路是每位依赖该治疗的患者的关键因素。当所有其他选择都用尽时,保留中心静脉导管可能是一个不错的选择,但导管留置时间延长可能会出现不良且罕见的并发症。
我们描述了一例65岁女性的病例,该患者自1986年因复杂性肾结石接受双侧肾切除术后一直接受血液透析治疗。她的最后一条血管通路是通过右颈内静脉植入的两根带隧道涤纶套的特西奥导管,正常使用了14年且无并发症,因此在此期间未进行更换。她因导管腔破裂被转诊至我院,通过建立更近端的隧道并切除受影响区域进行了保守治疗。几周后,同一腔再次出现破裂,因此在血管造影控制下更换了导管。导管很脆弱,因此在拔除时,尖端断裂并留在右心室,通过血管内迅速取出,无并发症。
本病例报告了与导管操作相关的两种罕见并发症,并确定了一种保守解决导管腔破裂的可能技术。
