下腔静脉滤器置入预防肺栓塞

背景:下腔静脉滤器置入预防肺栓塞是有效的,也为手术取栓提供了安全保障。目的:探讨下腔静脉滤器临床应用的研究进展。方法:由第一作者检索1985/2010FMJS数据库及万方数据库有关下腔静脉滤器材料学的发展,置入的适应证、禁忌证,置入技术,并发症及置入后抗凝问题方面的文献。结果与结论:下腔静脉滤器材料学发展迅速,其置入技术显著提高,但对其临床应用指针还没有统一的认识。对于置入后抗凝问题认识也存在差异,而滤网位置偏移、游走、成角及腔静脉穿孔和对周围脏器的损伤报道随着下腔静脉滤器应用的增多而相应增多。下腔静脉滤器置入预防肺栓塞的临床疗效是值得肯定的,但应该高度重视置入后的并发症及其严重性,相信随着下腔静脉滤器材料学的进一步发展及生物相容性的提高,其临床应用前景会越来越广阔。

Implantation of inferior vena cava filter in preventing pulmonary embolism

BACKGROUND: Inferior vena cava filter placement can efficiently prevent pulmonary embolism and provide security for surgical thrombectomy. OBJECTIVE: To explore the development of clinical application of inferior vena cava filters. METHODS: A computer-based online search was performed in FMJS database and Wanfang database between 1985 and 2010 for literatures related to the development, indications and contraindications, placement technologies, complications and postoperative anticoagulation of inferior vena cava filters. RESULTS AND CONCLUSION: Material science of inferior vena cava filters is developing rapidly, and their placement technologies have been improved significantly, but their clinical application indications are still unclear. Cognitions on postoperative anticoagulation is also different, and reports of filter position deviation, migration, angulation, and vena cava perforation, and damage to the surrounding organs are increasing with the increase of inferior vena cava filter application. The placement of inferior vena cava filters in preventing pulmonary embolism deserves affirmation, while the postoperative complications and severity of inferior vena cava filters need more researches. The clinical application prospects will be widening with further improvement in development and biocompatibility of material science of inferior vena cava filters.
