Prior to the introduction of virally inactivated clotting factor concentrates, the majority of patients with haemophilia became infected with the hepatitis C virus. Although transjugular liver biopsy can be safely performed in these patients, the procedure is associated with a significant financial burden mainly related to replacement therapy with clotting factor. The purpose of this study was to evaluate the feasibility and safety of transjugular liver biopsy in patients with haemophilia substituted with clotting factor concentrates for major surgical procedures. Over the last 5 years, transjugular liver biopsy was performed in nine patients with haemophilia within 1-10 days after orthopaedic (7), thoracic (1) or abdominal surgery (1). All patients had abnormal liver function tests and persistent hepatitis C viraemia. At the time of the biopsy, patients received recombinant factor VIII delivered by dose-adjusted continuous infusion through a central catheter inserted preoperatively in the left internal jugular (n = 8) or in an ante-cubital vein (n = 1). Before the biopsy, basal FVIII levels were raised to 80-100% by a bolus infusion and maintained above 80% for 24 h. The biopsy was informative in all cases. Only one patient developed an episode of supraventricular dysrhythmia. No bleeding or infectious complications were observed. When compared with elective liver biopsy performed outside the postsurgical period, the cost-savings per biopsy were 19 875 +/- 2660 euro. This study shows that intensive replacement therapy required by surgical procedures provides a safe and cost-effective opportunity for transjugular liver biopsy in patients with haemophilia and active hepatitis C.
在病毒灭活凝血因子浓缩物引入之前,大多数血友病患者感染了丙型肝炎病毒。尽管经颈静脉肝活检可以在这些患者中安全进行,但该操作与巨大的经济负担相关,主要与凝血因子替代治疗有关。本研究的目的是评估在因重大外科手术而用凝血因子浓缩物替代治疗的血友病患者中进行经颈静脉肝活检的可行性和安全性。在过去5年中,9例血友病患者在骨科手术(7例)、胸科手术(1例)或腹部手术(1例)后1 - 10天内接受了经颈静脉肝活检。所有患者肝功能检查均异常且持续存在丙型肝炎病毒血症。活检时,患者通过术前插入左颈内静脉(n = 8)或肘前静脉(n = 1)的中心导管经剂量调整的持续输注接受重组因子VIII。活检前,通过推注使基础FVIII水平升至80 - 100%,并维持24小时以上80%。所有病例的活检均提供了有用信息。仅1例患者发生了室上性心律失常。未观察到出血或感染并发症。与手术后期以外进行的择期肝活检相比,每次活检节省的费用为19875 +/- 2660欧元。本研究表明,外科手术所需的强化替代治疗为患有血友病和活动性丙型肝炎的患者进行经颈静脉肝活检提供了安全且具有成本效益的机会。
