Many studies have reported lead migration and breakage as complications of epidural spinal cord stimulation. In cases where rapid changes in physique such as those caused by pregnancy are expected, it is unclear whether extra consideration regarding possible adjustments and care to avoid complications such as lead breakage are required.
This article presents a case in which spinal cord stimulation was used to manage these complications in a woman during the perinatal period.
Case report.
Pain management clinic.
The patient was a 36-year-old female, approximate weight of 100 pounds, and 5-foot 1 inch in height, whose chief complaint was lower back and bilateral leg pain. The pain could not be alleviated by conservative therapies such as nerve blockade, oral medications with non-steroidal anti-inflammatory drugs, antidepressants, anticonvulsants or physical therapy. A spinal cord stimulator was implanted at another facility, which relieved the pain. The patient subsequently had 2 vaginal births without any problems relating to the stimulation sites, and both infants were healthy. She experienced lead breakage after the third vaginal birth that led to the subsequent reimplantation procedure.
The patient had 2 subsequent vaginal births following the initial implantation with no problems related to the stimulation sites, and both infants were healthy. At age 34, following her third vaginal birth, the stimulator became ineffective and was removed. The withdrawn lead wire was found to be broken in 2 places.
A case report.
Pregnancy following implantation of a spinal cord stimulator might result in lead breakage as abdominal girth increases. The present case exemplifies how pregnancy following implantation of a spinal cord stimulator might cause lead breakage as abdominal girth increases. Extra care is required to prevent lead breakage when anchors are fixed.
许多研究报告了硬膜外脊髓刺激的并发症，包括铅迁移和断裂。在预计体型会发生快速变化（例如怀孕）的情况下，尚不清楚是否需要额外考虑可能的调整和护理，以避免铅断裂等并发症。
本文介绍了一例在围产期使用脊髓刺激来处理这些并发症的病例。
病例报告。
疼痛管理诊所。
患者为 36 岁女性，体重约 100 磅，身高 5 英尺 1 英寸，主要抱怨是下背部和双侧腿部疼痛。保守治疗如神经阻滞、口服非甾体抗炎药、抗抑郁药、抗惊厥药或物理治疗均无法缓解疼痛。在另一家医疗机构植入脊髓刺激器后，疼痛得到缓解。随后，患者进行了 2 次阴道分娩，刺激部位均无问题，且婴儿均健康。第 3 次阴道分娩后，她出现了铅断裂，随后进行了重新植入手术。
初始植入后，患者进行了 2 次后续的阴道分娩，刺激部位均无问题，且婴儿均健康。34 岁时，她进行了第 3 次阴道分娩，刺激器失效并被取出。抽出的导线发现有 2 处断裂。
病例报告。
脊髓刺激器植入后怀孕可能会导致铅迁移和断裂，因为腹部周长增加。本病例说明了脊髓刺激器植入后怀孕可能会导致铅迁移和断裂，因为腹部周长增加。在固定锚定时需要特别注意防止铅断裂。
