[摘要] 目的 探討產(chǎn)后靜脈血栓的發(fā)生率、危險因素、發(fā)生時間、臨床表現(xiàn)及診斷，避免過渡治療。 方法 對2012年1月—2018年12月?lián)P州大學附屬醫(yī)院揚州市婦幼保健院（以下簡稱“我院”）收治47 948名孕產(chǎn)婦中5例產(chǎn)后發(fā)生靜脈血栓者的臨床資料進行回顧性分析。按2015年4月英國皇家婦產(chǎn)科醫(yī)師學會發(fā)布了關(guān)于降低妊娠期及產(chǎn)褥期靜脈血栓栓塞疾病發(fā)生風險的診療指南中標準進行評分，并且比較患者分娩前、血栓發(fā)現(xiàn)時凝血功能的差異。同時與我院2018年晚期妊娠無并發(fā)癥及合并癥的正常孕婦6525名的分娩前凝血功能進行比較。 結(jié)果 5例患者均經(jīng)綜合性醫(yī)院及我院彩色多普勒超聲或CT肺動脈造影確診，深靜脈血栓3例，淺靜脈血栓2例，深靜脈血栓中1例肺栓塞。近6年發(fā)生率為（1.04～1.07）/萬。5例患者均發(fā)生在產(chǎn)后1周內(nèi)，5例患者中1例危險因素評分為4分，1例患者危險因素評分為3分，3例患者危險因素評分為1分。有下肢疼痛癥狀患者4例。5例患者分娩前、血栓發(fā)現(xiàn)時凝血功能比較，差異無統(tǒng)計學意義（P > 0.05），但與6525名正常孕婦的分娩前凝血功能比較，5例患者分娩前凝血酶原時間、凝血酶時間短于正常孕婦（P < 0.05），活化部分凝血酶原時間、國際標準化比值、纖維蛋白原、D-二聚體比較，差異無統(tǒng)計學意義（P > 0.05）。經(jīng)抗凝治療，5例患者均痊愈。 結(jié)論 產(chǎn)后靜脈血栓發(fā)病率低，分娩前PT、TT明顯縮短及分娩后出現(xiàn)下肢疼痛癥狀，警惕靜脈血栓的發(fā)生，一旦發(fā)生及早治療。

[Abstract] Objective To investigate the incidence， risk factors， occurrence time， clinical manifestations and diagnosis of postpartum venous thrombosis， and to avoid overtreatment. Methods The clinical data of five cases of postpartum venous thrombosis in 47 948 pregnant women admitted to Yangzhou Maternal and Child Care Service Centre （hereinafter referred to as “our hospital”） from January 2012 to December 2018 were retrospectively analyzed. The score according to the criteria set out in the April 2015 Royal College of Obstetricians and Gynaecologists guidelines on reducing the risk of venous thromboembolism during pregnancy and puerperium， the differences in clotting function before delivery and at the time of thrombus discovery were compared. Meanwhile， the coagulation function was compared with that of 6525 normal pregnant women without complications and complications in the third trimester pregnancy in our hospital in 2018. Results All five cases were confirmed by color doppler ultrasonography or CT pulmonary angiography in general hospitals and our hospital， including three cases of deep vein thrombosis， two cases of superficial vein thrombosis， and one case of deep vein thrombosis. In recent six years， the incidence was （1.04-1.07）/10 000. All of the five cases occurred within one week after delivery. Among the five patients， one case had a risk factor score of four， one case had a risk factor score of three， and three cases had a risk factor score of one. Four cases had lower extremity pain symptoms. Comparison of coagulation function between the five patients before delivery and at the time of thrombosis discovery showed no statistically significant difference （P > 0.05）. However， compared with the coagulation function before delivery of 6525 normal pregnant women， the prothrombin time （PT） and thrombin time （TT） of five cases before delivery were shorter than that of normal pregnant women （P < 0.05）. There were no significant differences in activated partial prothrombin time， international standardized ratio， fibrinogen and D-dimer （P > 0.05）. After anticoagulant therapy， all the five cases recovered. Conclusion The incidence of postpartum venous thrombosis is low， PT and TT before delivery are shortened significantly and lower limb pain symptoms appear after delivery.

低分子肝素、肝素是產(chǎn)后的首選抗凝治療，必要時可加用華法林，產(chǎn)后華法林對母乳喂養(yǎng)是安全的[2，20]。至于抗凝持續(xù)時間目前指南推薦至少到產(chǎn)后6周，?？鼓幬锴埃瑧?yīng)由血管外科醫(yī)師進行評估，以決定是否需要進一步治療[21]。

綜上所述，產(chǎn)后靜脈血栓發(fā)病率低，但發(fā)生都有一定危險因素，目前尚不能提供良好的篩查指標。產(chǎn)婦出現(xiàn)下肢疼痛癥狀以及分娩前PT、TT明顯縮短，產(chǎn)后形成靜脈血栓明顯增高。彩色多普勒超聲是最簡便的診斷方法，低分子肝素、肝素是產(chǎn)后的首選抗凝治療。避免過渡治療會造成患者經(jīng)濟負擔及出血風險，國內(nèi)需要進行流行病學數(shù)據(jù)分析，制訂出診療指南或共識。
