Cystic Artery Bleeding: Imaging Insights and Systematic Review of Endovascular Management

Background: Cystic artery bleeding (CAB) is a rare but potentially life-threatening condition. Its etiologies span iatrogenic trauma, inflammatory diseases, and trauma, often presenting variably as hemoperitoneum, upper gastrointestinal bleeding, or hemorrhagic shock. The clinical heterogeneity of CAB complicates its diagnosis, necessitating a high index of suspicion and reliance on imaging modalities, particularly computed tomography (CT), for accurate identification of bleeding sources and differentiation from other causes of abdominal pain. Methods: This pictorial essay highlights key imaging findings in CAB and pseudoaneurysms, emphasizing the role of ultrasound, CT, and digital subtraction angiography (DSA) in diagnosis and management planning. Additionally, a systematic review of transcatheter arterial embolization (TAE) is presented, consolidating data from 64 studies encompassing 90 patients. Results: The review evaluates patient demographics, etiologies, clinical presentations, and procedural outcomes, underscoring TAE’s high efficacy and safety as a first-line treatment. Conclusions: The findings reinforce the importance of early diagnosis and tailored intervention strategies to optimize outcomes in CAB management.
