Hereditary hemorrhagic telangiectasia (HHT), also called Osler-Weber-Rendu syndrome, is an autosomal dominant genetic disease that affects the vasculature of numerous organs. The prevalence of HHT is estimated to be between 1.5 and 2 persons per 10,000. While there is still much to learn about this condition, there is an increasing understanding its underlying pathophysiology, genetic basis, presentations, and management. Recognizing that the clinical manifestations of HHT can involve a number of organ systems will provide clinicians with a higher index of suspicion for the disease. This early diagnosis and genotyping can greatly reduce mortality for a patient with HHT through appropriate screening for complications. This review will focus on the gastrointestinal manifestations of HHT and how these can dictate treatment and prognosis.
遗传性出血性毛细血管扩张症(HHT),也称为奥斯勒-韦伯-伦杜综合征,是一种常染色体显性遗传病,会影响多个器官的脉管系统。据估计,HHT的患病率为每10000人中有1.5至2人。尽管对于这种病症仍有许多有待了解之处,但人们对其潜在的病理生理学、遗传基础、表现形式及治疗方法的认识正在不断加深。认识到HHT的临床表现可能涉及多个器官系统,将提高临床医生对该疾病的怀疑指数。这种早期诊断和基因分型通过对并发症进行适当筛查,可大大降低HHT患者的死亡率。本综述将聚焦于HHT的胃肠道表现以及这些表现如何决定治疗和预后。
