Splenic artery aneurysm was first described by Beaussier in 1770, and the first successful treatment was reported by McLeod in 1940. The splenic artery aneurysm is considered the most common splanchnic site for aneurysm formation, affecting 46 to 60% of patients with visceral aneurysms. Most patients are asymptomatic, and splenic artery aneu- rysm...

Background
Abdominal aortic aneurysms (AAAs) are the most common. The annual incidence of AAA rupture is eight cases per 100,000 inhabitants. Incidental detection can benefit patients if diameter is monitored and the correct treatment provided.
Objectives
To estimate the prevalence of incidental diagnosis of thoracic aortic aneurysm (TAA) and AAA by computed tomography (CT); to determine prevalence by age and sex of patients and determine which arteries are involved and the morphological characteristics of the aneurysms; to determine the indications for CT most associated with incidental diagnosis of aneurysms.
Methods
This was a descriptive, retrospective and randomized study. Inclusion criteria: patients over 50 years of age examined with CT of the thorax, abdomen or pelvis. Exclusion criteria: follow-up or diagnostic suspicion of aneurysms. Data collection instruments containing questions covering demographic and anatomic data were used.
Results
A sample of 1,202 radiology reports was reviewed. A total of 27 aneurysms were detected (prevalence of 2.2%). Patients: 60% were male and 40% were female (p < 0.05). Sites: there were 13 cases (48.2%) in the ascending aorta (TAA); 7 (25.9%) in the infrarenal aorta (AAA); 2 (7.4%) at the thoracoabdominal transition of the aorta (TTA); 2 (7.4%) in the common iliac artery ; 1 (3.7%) in the internal iliac artery; 1 (3.7%) in the splenic artery; and 1 (3.7%) in the renal artery.
Conclusions
The majority of patients were male (60%); TAA was the most common type (mean diameter: 4.1 cm), followed by AAA (mean diameter: 4.0 cm) and ATA (mean diameter: 3.9 cm). The most common indication for the CT examination that led to incidental diagnosis of an aneurysm was respiratory symptoms.

... They are asymptomatic in the majority of patients and splenic artery aneurysms tend to be diagnosed as an incidental finding when investigating some other abdominal disease using imaging. 1 Despite being the third most common type of abdominal artery aneurysm and the most common type of visceral artery aneurysm, splenic artery aneurysms are considered relatively rare. 2-4 A review of routine autopsies of the general population found a very low incidence of splenic artery aneurysm (0.01%), rising to 1% in the hypertense population and 10.4% in the elderly population. ...
The splenic artery is the visceral vessel that is most often affected by aneurysmal disease. Occasionally, gastrointestinal bleeding may signify that the aneurysm is in communication with the digestive tract. We report on the case of a 64-year-old multiparous patient with intermittent digestive bleeding caused by a splenic artery aneurysm who was successfully treated with endovascular embolization.

Introduction. Visceral artery aneurysms are uncommon. Among them, splenic artery is the most common (46-60%). Most splenic artery aneurysms are asymptomatic and diagnosed incidentally, but its rupture, potentially fatal, occurs in up to 8% of cases. Presentation of Case. A female patient, 64 years old, diagnosed with a giant aneurysm of the splenic artery (approximately 6.5 cm in diameter) was successfully submitted to endovascular treatment by stent graft implantation. Discussion. Symptomatic aneurysms and those larger than 2 cm represent some of the main indications for intervention. The treatment may be by laparotomy, laparoscopy, or endovascular techniques. Among the various endovascular methods discussed in this paper, there is stent graft implantation, a method still few reported in the literature. Conclusion. Although some authors still consider the endovascular approach as an exception to the treatment of SAA, in major specialized centers these techniques have been consolidated as the preferred choice, reserving the surgical approach in cases where this cannot be used. For being a less aggressive approach, it offers an opportunity of treatment to patients considered "high risk" for surgical treatment by laparotomy/laparoscopy.
A 22 year old female with a history of recurrent abdominal pain was transferred to our institution with a diagnosis of splenic artery aneurysm identified on imaging. CT angiography of the abdomen and pelvis revealed a partially thrombosed 3.0 cm splenic artery aneurysm without signs of rupture and with an anomalous origin from the superior mesenteric artery. The patient was successfully treated with endovascular exclusion of the aneurysm. Herein we review some of the nuances of endovascular repair of splenic artery aneurysm.
