Splenic artery (SA) aneurysm and pseudoaneurysm are rare pathologies and uncommon causes of massive upper gastrointestinal (GI) bleeding. They represent the third most common intra-abdominal aneurysms. Variations in the origin of SA are relatively common and asymptomatic. However, the presence of an accessory SA that is symptomatic is quite atypical. In this report, we describe the case of a 73-year-old female who presented with massive upper GI bleeding caused by a pseudoaneurysm of a superior polar artery with an unusual anatomic origin. The patient was successfully treated endovascularly with transarterial coil embolization. Early diagnosis and interventional management are crucial for patient's survival; hence, it must be kept in mind as possible etiology of life-threatening GI bleeding to reduce morbidity and mortality.
脾动脉（SA）动脉瘤和假性动脉瘤是罕见的病变，也是上消化道（GI）大出血的不常见原因。它们是腹腔内第三常见的动脉瘤。脾动脉起源的变异相对常见且无症状。然而，存在有症状的副脾动脉则相当不典型。在本报告中，我们描述了一例73岁女性患者，其因上极动脉假性动脉瘤伴异常解剖起源导致上消化道大出血。该患者通过经动脉线圈栓塞术成功进行了血管内治疗。早期诊断和介入治疗对患者的生存至关重要；因此，必须将其视为危及生命的消化道出血的可能病因，以降低发病率和死亡率。
