Cerebral ventricular shunt placements are the most common neurosurgical procedure performed today, which play a life-long role in the care of patients with hydrocephalus. Complication rates requiring shunt replacement are as high as 25%, and the potential need for multiple revisions throughout a patient's life may result in the formation of scar tissue and compromised wound healing. Without addition of vascularized tissue, patients with scalp scarring and impaired wound healing then enter a cycle of impaired skin closure followed by shunt infection, failure, and revision with little promise of long-term operative or therapeutic success. This plastics-neuro collaboration is the first known report of a free vastus lateralis muscle flap for coverage of a cerebral ventricular shunt, in a patient with congenital hydrocephalus and 17 previous ventricular shunts revisions due to infections and soft tissue exposure from scarring and a hostile wound bed. In the setting of extensive scarring, the free vascularized muscle flap provides soft tissue and vascular supply capable of promoting wound healing, maintaining scalp integrity, and reducing the incidence of shunt infection and the subsequent need for future revision, as supported by the complication-free status of the same patient now 16 months since the date of operation.
脑室分流术是目前最常见的神经外科手术,在脑积水患者的护理中发挥着终身作用。需要更换分流管的并发症发生率高达25%,患者一生中可能需要多次翻修,这可能导致瘢痕组织形成和伤口愈合受损。对于头皮瘢痕形成和伤口愈合受损的患者,如果不添加血管化组织,就会进入皮肤闭合受损、继而发生分流管感染、故障以及翻修的循环,长期手术或治疗成功的希望渺茫。这种整形与神经外科的合作是首次报道采用游离股外侧肌皮瓣覆盖脑室分流管,该患者患有先天性脑积水,此前因感染以及瘢痕形成和不良伤口床导致的软组织暴露,已进行了17次脑室分流管翻修。在广泛瘢痕形成的情况下,游离血管化肌皮瓣可提供软组织和血管供应,能够促进伤口愈合、维持头皮完整性、降低分流管感染的发生率以及减少后续翻修的必要性,自手术之日起16个月,该患者目前无并发症的状态证明了这一点。
