Abstract

Hypoxemia in coronavirus disease 2019 (COVID-19) patients is not solely due to alveolar damage but can also involve factors like vascular shunts, such as pulmonary arteriovenous malformation, contributing to persistent hypoxemia. We report a case of a 59-year-old male, with COVID-19 pneumonia, requiring high-flow respiratory support, who later was also diagnosed with a large pulmonary arteriovenous fistula, which probably worsened because of COVID-19 infection.

Learning points: Hypoxemia in coronavirus disease 2019 (COVID-19) patients is multifaceted not only with alveolar damage but also with other factors such as vascular shunts, like pulmonary arteriovenous malformation.Diagnosing pulmonary arteriovenous malformation can be difficult due to overlapping symptoms with other respiratory disorders.Management of pulmonary arteriovenous malformation typically involves transcatheter embolization to block abnormal vascular connections and reduce the risk of complications like paradoxical emboli. Surgical options are reserved for severe cases, while pharmacological treatments are less common.

肺动静脉畸形：Covid-19 期间的低氧血症不尽相同。

2019冠状病毒病（COVID-19）患者的低氧血症不仅是由于肺泡损伤，还可能涉及血管分流等因素，如肺动静脉畸形，导致持续低氧血症。我们报告了一例59岁男性，患有COVID-19肺炎，需要高流量呼吸支持，后来也被诊断为大肺动静脉瘘，可能因COVID-19感染而恶化。学习要点：2019冠状病毒病（COVID-19）患者的低氧血症是多方面的，不仅与肺泡损伤有关，还与其他因素有关，如血管分流，如肺动静脉畸形。由于与其他呼吸系统疾病的症状重叠，诊断肺动静脉畸形可能很困难。肺动静脉畸形的治疗通常包括经导管栓塞，以阻断异常血管连接，降低异位栓塞等并发症的风险。手术选择保留给严重的病例，而药物治疗不太常见。

期刊介绍： The European Journal of Case Reports in Internal Medicine is an official journal of the European Federation of Internal Medicine (EFIM), representing 35 national societies from 33 European countries. The Journal''s mission is to promote the best medical practice and innovation in the field of acute and general medicine. It also provides a forum for internal medicine doctors where they can share new approaches with the aim of improving diagnostic and clinical skills in this field. EJCRIM welcomes high-quality case reports describing unusual or complex cases that an internist may encounter in everyday practice. The cases should either demonstrate the appropriateness of a diagnostic/therapeutic approach, describe a new procedure or maneuver, or show unusual manifestations of a disease or unexpected reactions. The Journal only accepts and publishes those case reports whose learning points provide new insight and/or contribute to advancing medical knowledge both in terms of diagnostics and therapeutic approaches. Case reports of medical errors, therefore, are also welcome as long as they provide innovative measures on how to prevent them in the current practice (Instructive Errors). The Journal may also consider brief and reasoned reports on issues relevant to the practice of Internal Medicine, as well as Abstracts submitted to the scientific meetings of acknowledged medical societies.
