Abstract
Gastrointestinal bleeding (GIB) among cancer patients is a major source of morbidity and mortality. Although a wide variety of etiologies contribute to GIB, special considerations should be made for cancer-related factors such as the type of malignancy, location and extent of disease, hemostatic parameters, and treatment effects. Key imaging modalities used to evaluate GIB include computed tomography angiography (CTA), radionuclide imaging, and catheter-based angiography. Understanding the cancer and treatment history and recognizing the associated imaging manifestations are important for identifying the source and potential causes of GIB in cancer patients. This article will review the common clinical presentations, causes, imaging manifestations, and angiographic management of GIB in cancer patients.
摘要
癌症患者的胃肠道出血（GIB）是发病率和死亡率的主要原因。尽管有多种病因可导致 GIB，但应特别考虑与癌症相关的因素，如恶性肿瘤类型、疾病的位置和范围、止血参数和治疗效果。用于评估 GIB 的主要影像学方式包括计算机断层血管造影（CTA）、放射性核素成像和基于导管的血管造影。了解癌症和治疗史，并识别相关的影像学表现，对于确定癌症患者 GIB 的来源和潜在原因非常重要。本文将回顾癌症患者 GIB 的常见临床表现、病因、影像学表现和血管造影处理。
