Splenic artery aneurysm is rare and its diagnosis is challenging due to the nonspecific nature of the clinical presentation. We report a case of a splenic artery aneurysm in which the patient presented with chronic dyspepsia and multiple episodes of minor intragastric bleeding.
A 60-year-old, previously healthy Sri Lankan man presented with four episodes of hematemesis and severe dyspeptic symptoms over a period of 6 months. The results of two initial upper gastrointestinal endoscopies and an abdominal ultrasound scan were unremarkable. A third upper gastrointestinal endoscopy detected a pulsatile bulge at the posterior wall of the gastric antrum. A contrast-enhanced computed tomogram of his abdomen detected a splenic artery aneurysm measuring 3 × 3 × 2.5 cm. While awaiting routine surgery, he developed a torrential upper gastrointestinal bleeding and shock, leading to emergency laparotomy. Splenectomy and en bloc resection of the aneurysm with the posterior stomach wall were performed. Histology revealed evidence for a true aneurysm without overt, acute, or chronic inflammation of the surrounding gastric mucosa. He became completely asymptomatic 2 weeks after the surgery.
Splenic artery aneurysms can result in recurrent upper gastrointestinal bleeding. The possibility of impending catastrophic bleeding should be remembered when managing patients with splenic artery aneurysms after a minor bleeding. Negative endoscopy and ultrasonography should require contrast-enhanced computed tomography to look for the cause of recurrent upper gastrointestinal bleeding.
脾动脉瘤较为罕见,因其临床表现缺乏特异性,诊断颇具挑战性。我们报告一例脾动脉瘤病例,该患者表现为慢性消化不良及多次轻微胃内出血。
一名60岁、既往健康的斯里兰卡男性,在6个月内出现4次呕血及严重消化不良症状。最初两次上消化道内镜检查及腹部超声扫描结果均无异常。第三次上消化道内镜检查发现胃窦后壁有一搏动性隆起。腹部增强计算机断层扫描发现一个大小为3×3×2.5厘米的脾动脉瘤。在等待常规手术期间,他发生了上消化道大出血并休克,遂进行急诊剖腹手术。实施了脾切除术以及连同胃后壁整块切除动脉瘤。组织学检查显示为真性动脉瘤,周围胃黏膜无明显急性或慢性炎症。术后2周他完全无症状。
脾动脉瘤可导致反复上消化道出血。在处理轻微出血后的脾动脉瘤患者时,应牢记有发生灾难性出血的可能性。内镜检查和超声检查结果为阴性时,应进行腹部增强计算机断层扫描以查找反复上消化道出血的原因。
