同型半胱氨酸水平是整形和重建手术中伤口愈合受损的潜在因素。
整形和重建手术(PRS)在很大程度上依赖于可靠的组织灌注。尽管有证据支持同型半胱氨酸水平,包括高同型半胱氨酸血症(HHcy)的存在,对伤口愈合和皮瓣血栓形成的影响,但通常不将其纳入围手术期风险评估模型。同型半胱氨酸通过诱导内皮功能障碍、产生活性氧化物质、降低一氧化氮的可用性和损害血管舒张来破坏组织愈合。它还会激活炎症信号,干扰胶原蛋白的交联,这是伤口强度的必要过程。这在PRS中尤其重要,因为在PRS中,愈合发生在大的重建领域,包括那些先前已经手术或照射过的领域。prs特异性数据仍然有限,因为只有一项动物模型研究表明,严重的HHcy显著增加皮瓣坏死率、微血管造影和炎症浸润,表明直接损害组织活力和修复。在显微外科重建中,有潜在高凝状态的患者,包括HHcy,血栓形成并发症的发生率很高,一旦血栓形成,完全缺乏挽救,这表明即使对内皮功能和凝血的中度损害也可能导致皮瓣严重受损。同型半胱氨酸整合在PRS风险模型中的差距是重要的,因为它可能通过叶酸和b族维生素状态等因素进行修改。同型半胱氨酸水平可以为围手术期优化提供机会,而无需增加资源或显著的成本负担,并将其纳入评估框架可以为减少高风险患者的伤口愈合并发症提供可行的机会。需要前瞻性试验来评估这一点,以及同型半胱氨酸水平的改善是否能促进复杂重建病例的愈合。标准化的临床终点,包括上皮化时间、伤口开裂、部分皮瓣坏死和感染率,都应记录在案。皮瓣特异性变量,如皮瓣类型、分期重建和麻醉剂也可以评估,而患者因素,如白蛋白、糖尿病、外周疾病和吸烟应加以控制。

期刊介绍: The Journal of Reconstructive Microsurgery is a peer-reviewed, indexed journal that provides an international forum for the publication of articles focusing on reconstructive microsurgery and complex reconstructive surgery. The journal was originally established in 1984 for the microsurgical community to publish and share academic papers. The Journal of Reconstructive Microsurgery provides the latest in original research spanning basic laboratory, translational, and clinical investigations. Review papers cover current topics in complex reconstruction and microsurgery. In addition, special sections discuss new technologies, innovations, materials, and significant problem cases. The journal welcomes controversial topics, editorial comments, book reviews, and letters to the Editor, in order to complete the balanced spectrum of information available in the Journal of Reconstructive Microsurgery. All articles undergo stringent peer review by international experts in the specialty.
