Abstract
BACKGROUND
Giant splenic artery pseudoaneurysms (GSAPs) > 5 cm are a rare clinical entity. The aim of this study was to present our experience with 2 such patients successfully treated by coil embolization and surgery and review the pertinent literature.
METHODS
A 58-year-old woman and 57-year-old man with a history of chronic pancreatitis were diagnosed with GSAP based on computed tomography (CT) angiography. The first patient had a 6-cm pseudoaneurysm, which was successfully treated with transcatheter coil embolization using a sandwich exclusion method. The second patient had two 7-cm lesions, which were successfully treated with distal pancreatectomy and splenectomy.
RESULTS
Postembolization CT angiography at 12 months showed remaining calcified pseudocyst without evidence of pseudoaneurysm in the first patient. Both patients remained well and symptom-free at 12 months.
CONCLUSIONS
Combined with the experience of the previous literature, we believe that management of GSAP should be tailored for each individual case depending on the location and number of pseudoaneurysms, the underlying etiology, and the patient's hemodynamic status. Embolization should be considered as the first-line treatment for clinically stable patients with GSAP, whereas GSAPs with a pseudocyst are best treated with surgery.
