Splenic artery aneurysms (SAAs) are the third most frequent intra-abdominal aneurysm, following abdominal aorta and iliac artery aneurysms. SAAs are classified according to their involvement of arterial wall layers: true aneurysms involve all 3 layers (intima, media, and adventitia), and pseudoaneurysms involve only one or two. Herein we present a new case of giant pseudo SAA. A 65-year-old female patient with a pancreatic mass and iron deficiency was referred to our clinic for further investigation. Abdominal ultrasonography, contrast-enhanced CT and magnetic resonance imaging showed a lesion resembling a subcapsular hemangioma in the spleen, and aneurysmatic dilation of the splenic artery with a diameter of >5 cm. The large size of the aneurysm and the clinical findings were indications for surgical treatment. The patient underwent en bloc resection of the spleen, distal pancreas, and aneurysmatic segment of the splenic artery. The patient remains complication-free 2 months after the operation. Spontaneous rupture is the most important life-threatening complications of giant SAAs. Therefore, all symptomatic patients with SAA should be treated, as well as asymptomatic patients with lesions >= 2 cm, who are pregnant or fertile, have portal hypertension, or are candidates for liver transplantation. Despite advances in endovascular techniques, conventional abdominal surgery remains the gold standard for treatment. |
