A 64-year-old man with cirrhosis of the liver had a palpable, pulsatile palm-size mass over the upper abdomen. Splenic artery aneurysm was diagnosed by sonography, computed tomography scan, and celiac angiography. Operative findings showed a huge splenic artery aneurysm (20 X 30 X 20 cm) over the middle portion of the splenic artery. Such a huge splenic artery aneurysm may develop because changes in splenic circulatory dynamics after a portocaval shunt, resulting in compression of the splenic vein and congestive splenomegaly.

Visceral artery aneurysms (VAAs) often rupture and cause serious morbidity or death. The purpose of this study was to identify conditions associated with VAA in a series of 30 patients treated at our institution from 1988 through 1998. Demographics, types of aneurysms, associated conditions, diagnoses, treatments, and outcomes were recorded and analyzed. Thirty patients (16 men and 14 women) with VAA were identified. The arteries involved were splenic (eight), renal (ten), hepatic (nine), hypogastric (one), celiac (one), and pancreaticoduodenal (one). Five of eight (63%) splenic artery aneurysms occurred in women; however, gender was not a factor in other aneurysmal groups. Splenic artery aneurysm also was associated with cirrhosis in four of the eight (50%) patients. Five of the nine (56%) hepatic artery aneurysms were associated with cirrhosis; two of these were pseudoaneurysms that occurred after liver transplantation. Five of ten (50%) renal artery aneurysms were associated with juxtarenal abdominal aortic aneurysms. Celiac and pancreaticoduodenal aneurysms were associated with gastrointestinal bleeding. Treatments included surgery (19), embolization (eight), and observation alone (three). These data demonstrate that association with other conditions varies according to subgroups of VAA. Despite advances in diagnosis and therapy the heterogeneity of VAA suggests that management must remain individualized.

Splenic artery aneurysms (SAAs), occurring in 7% to 17% of patients with cirrhosis, often result in catastrophic rupture after liver transplantation. We had experienced 3 cases of ruptured SAAs after adult living donor liver transplantation (LDLT), and we then performed this study to find risk factors for coexisting SAAs in liver transplant candidates with cirrhosis and to propose ideal approaches for them. Preoperative and postoperative computed tomography angiograms and axial views were reviewed for 310 adult LDLT recipients who had cirrhosis from January 2004 to August 2005. The recorded variables were the preoperative diagnosis, the presence of SAA and its characteristics, the splenic artery (SA) diameter, and the presence and size of portosystemic collaterals. Devastating SAA rupture accompanied by hypovolemic shock occurred on postoperative days 6, 82, and 8, respectively, and it was treated emergently by embolization in cases 1 and 2 and by splenectomy in case 3. Cases 1 and 3 recovered well, but case 2 died of an unrelated cause with a long hospital stay. The incidence of SAA during the study period was 14.2% (44/310), and the size was 16.6 +/- 5.7 mm. Most SAAs were single (70.6%, 31/44) and were located in the distal one-third of the SA (82.4%, 36/44). Large portosystemic collaterals demonstrating longstanding severe portal hypertension were significantly correlated with the occurrence of SAAs. Nine patients with SAAs were preventively treated by proximal ligation (n = 4) intraoperatively and by embolization (n = 5) 1 day before or after LDLT. No patient showed severe postembolization syndrome. In conclusion, a careful preoperative evaluation of SAAs by high-resolution 3-dimensional computed tomography in liver transplant candidates, especially in those showing large portosystemic collaterals, is merited. Preventive treatment should be encouraged regardless of the size in order to avoid severe morbidity and mortality related to SAA rupture, and methods such as radiological and surgical interventions need to be individualized according to the location and number of SAAs.

Splenic artery aneurysm is a rare condition with potential lethal complications. If associated with severe diseases, the diagnosis and management may be challenging. Usually, ultrasound examination is the first step in the diagnosis, and the specific ultrasound features suggest the diagnosis. When combined with contrast-enhanced ultrasound examination, the accuracy of ultrasound increases and can therefore rule out some severe complications. We present the case of a patient hospitalized with decompensated cirrhosis in whom the ultrasound examination revealed the presence of a high-risk splenic artery aneurysm. However, the treatment decisions were profoundly influenced by the liver disease complications.
