Amyloid A (SAA) and procalcitonin (PCT) have been reported as useful indicators of inflammation. Our aim was to assess the utility of SAA and PCT in establishing the severity of acute pancreatitis in comparison to C-reactive protein (CRP): Thirty-one patients with acute pancreatitis enrolled within 24 hr from the onset of pain and 31 healthy subjects were studied. Nineteen patients had mild acute pancreatitis, and 12 had severe pancreatitis. Serum SAA, PCT, and CRP were measured in all subjects at admission and, in acute pancreatitis patients, during the following five days. Patients with acute pancreatitis had serum concentrations of SAA, PCT, and CRP significantly higher (P < 0.001) than those of healthy subjects during the entire study period. Using cutoff values ranging from 240 to 250 mg/liter for SAA, from 0.252 to 0.255 ng/ml for PCT, and from 12.8 to 12.9 mg/dl for CRP, the sensitivity (calculated on patients with severe pancreatitis), the specificity (calculated on patients with mild pancreatitis), and the efficiency (calculated as the percentage of correct classifications) were 76.8%, 69.3%, and 72.4% for SAA; 21.7%, 83.2%, and 58.2% for PCT; and 60.9%, 89.1%, and 77.6% for CRP. In conclusion, the sensitivity of SAA is significantly higher than that of PCT and CRP in assessing the severity of pancreatitis, whereas PCT and CRP had a specificity significantly higher than SAA. The accuracy and efficiency were similar for SAA and CRP, and both these markers had an accuracy and efficiency significantly higher than those of PCT.

Endovascular intervention can provide an alternative method of treatment for visceral artery aneurysms. We conducted a retrospective review of all patients with visceral artery aneurysms at a single university medical center from 1990 to 2003, focusing on the outcome of endovascular therapy. Sixty-five patients with visceral artery aneurysms were identified: 39 splenic (SAA), 13 renal, seven celiac, three superior mesenteric (SMA), and three hepatic. Eleven patients (16.9%) had symptoms attributable to their aneurysms, which included a total of four ruptures (6.2%): three splenic and one hepatic. Management consisted of 18 (27.7%) endovascular interventions, nine (13.9%) open surgical repairs, and 38 (58.5%) observations. Mean aneurysm diameter for patients treated expectantly was significantly less than for those who underwent intervention (p = 0.001). Endovascular interventions included 15 (83.3%) embolizations (11 SAA, three renal, one hepatic) and three (16.7%) stent grafts (two SMA, one renal). The initial technical success rate of the endovascular procedures was 94.4% (17/18). However, there were four patients (22.2%) with major endovascular procedure-related complications: one late recurrence requiring open surgical repair, two large symptomatic splenic infarcts, and one episode of severe pancreatitis. These four patients had distal splenic artery aneurysms at or adjacent to the splenic hilum. There were no endovascular procedure-related deaths. Reasons for performing open surgical repair included three SAA ruptures diagnosed at laparotomy and complex anatomy not amenable to endovascular intervention (six patients). One surgical patient had a postoperative small bowel obstruction treated nonoperatively; and there was one perioperative death in a patient operated on emergently for rupture. Endovascular management of visceral artery aneurysms is a reasonable alternative to open surgical repair in carefully selected patients. Individual anatomic considerations play an important role in determining the best treatment strategy if intervention is warranted. However, four of 11 (36.4%) patients with distal splenic artery aneurysms treated with endovascular embolization developed major complications. Based on our experience, traditional surgical treatment of SAA with repair or ligation and concomitant splenectomy when necessary may be preferred in these cases.
