神经外科患儿下肢深静脉血栓形成的原因初探

Primary study on deep venous thrombosis in children after neurosurgery

目的了解神经外科患儿下肢深静脉血栓发生率，探讨可能的相关原因。方法选择我院2007年1月至2011年12月诊断下肢深静脉血栓以及同期非血栓的神经外科患儿，统计比较其原发疾病以及手术时间等临床资料，分析可能引起深静脉血栓的原因。结果18例出现下肢深静脉血栓的患儿，均有下肢深静脉置管的操作，主要的原发病为颅咽管瘤，手术时间较非血栓患儿明显延长（P〈0．001）。结论神经外科患儿下肢深静脉血栓发生原因是多方面的，既与深静脉置管及其放置时间相关，同时又与神经外科疾病种类相关。

Objective To study the incidence and related causes of deep venous thrombosis of lower extremities in children after neurosurgery. Methods The children with or without deep venous thrombosis of lower extremities after neurosurgery in our hospital from January 2007 to December 2011 were selected. The clinical data including primary diseases and operation time were collected to be compared to find the related causes of deep vein thrombosis. Results There were 18 children with postoperative deep venous thrombosis. All of them had deep venouscathcter invasive operation. The major primary disease was craniopharyngioma. They all had longer operation time compared with those without thrombosis. Conclusions The causes of deep venous thrombosis in neurosurgical children involve not only deep venous catheter - related but also neurological primary disease and operation time.
