The risk of TE in IBD patients has been demonstrated to be approximately three-fold higher as compared to the general population. The pathogenesis of thrombosis in IBD patients is multifactorial and not fully explained. The most commonly listed factors include genetic and immune abnormalities, disequilibrium between procoagulant and anticoagulant factors, although recently, the role of endothelial damage as an IBD-triggering factor is underlined. Several studies report that the levels of some coagulation enzymes, including fibrinogen, factors V, VII, VIII, active factor XI, tissue factor, prothrombin fragment 1 + 2 and the thrombin-antithrombin complex, are altered in IBD patients. It has been demonstrated that there is a significant decrease of tissue plasminogen activator level, a marked increase of plasminogen activator inhibitor type 1 and thrombin-activable fibrinolysis inhibitor, a significantly lower level of antithrombin III and tissue factor pathway inhibitor. IBD patients have been also observed to produce an increased amount of various anticoagulant antibodies. Hyperhomocysteinemia, which is a potential risk factor for TE was also observed in some IBD patients. Further studies are necessary to assess the role of coagulation abnormalities in IBD etiology and to determine indications for thromboprophylactic treatment in patients at high risk of developing TE.展开更多
经外周静脉穿刺中心静脉置管(peripherally inserted central venous catheters,PICC)是一种易于操作,有效时间长且安全的技术,自从引入便被快速推广于临床,该技术可有效减少穿刺血管的作用次数,进而减少药物刺激和血胸等并发症的发病率...经外周静脉穿刺中心静脉置管(peripherally inserted central venous catheters,PICC)是一种易于操作,有效时间长且安全的技术,自从引入便被快速推广于临床,该技术可有效减少穿刺血管的作用次数,进而减少药物刺激和血胸等并发症的发病率[1-2]。不过在临床应用过程中,不断出现导管脱落和堵塞、感染以及血栓等相关问题,导致患者治疗时间延长、医药费增加,甚至出现死亡[3]。近年来,随着学者不断深入研究、总结,PICC相关性血栓发生原因逐渐明确,且预防PICC相关性血栓新的方法不断涌现。展开更多

It occurs secondary to abdominal malignancy, infection or surgical intervention. PVT is commonly forgotten as a possible cause of abdominal pain. The clinical picture may vary but abdominal pain and low grade fever are the most characteristic picture. METHODS: A 58-year-old male patient was admitted to our hospital complaining of abdominal pain for three days. CT scan revealed an edematous area around the portal vein. Doppler ultrasonography showed evidence of a portal vein thrombosis. RESULTS: PVT can be diagnosed with CT and Doppler ultrasonography. Fresh thrombus can be undetected by sonography because of the low echogenity but can be recognised by color Doppler ultrasonography. Treatment ranges from observation and bowel rest to surgical resection of bowel. CONCLUSIONS: When we suspect a case of PVT, it should be treated at an early stage to prevent being lost in a diagnostic dilemma. The immediate use of anticoagulant could be important in preventing serious consequences of PVT.展开更多

Their levels were 24. 40± 10. 30 μg/L, 26. 99±5.77 μg/L,38. 81±6. 28 μg/L, 79. 74± 18. 76 μg/L, respectively. The level of urinary FPA in renal insufficiency function group was significantly higher than those of the con-trol group and normal renal function group (P<0.01). The patients with uremia presented dramatically higher level of urinary FPA than those in the renal insufficiency group (P<0.01). A positive correlation was found between the level of urinary FPA and the blood creatine (r= 0. 9120, P<0. 01 ). It was suggested that a hypercoagulable state existed in the patients with chronic nephritis with renal failure, in which the severity was closely related with the occurrence and development of the disease. The urinary FPA could serve as a good indicator for renal function.展开更多
