Rupture of Pancreaticoduodenal Artery Aneurysm Caused by Superior Mesenteric Artery Embolism

We present a case of combined celiac axis and superior mesenteric artery embolism in a 70-year-old patient that was examined in emergency department for atrial fibrillation and diffuse abdominal pain. Standard abdominal x-ray showed air in the portal vein. CT scan with contrast showed air in the lumen of the stomach and small intestine, bowel distension with wall thickening, and a free gallstone in the abdominal cavity. Massive embolism of both celiac axis and superior mesenteric artery was seen after contrast administration. On laparotomy, complete necrosis of the liver, spleen, stomach and small intestine was found. Gallbladder was gangrenous and perforated, and the gallstone had migrated into the abdominal cavity. We found free air that crackled on palpation of the veins of the gastric surface. The patients condition was incurable and she died of multiple organ failure a few hours after surgery. Acute visceral thromboembolism should always be excluded first if a combination of atrial fibrillation and abdominal pain exists. Determining the serum levels of d-dimers and lactate, combined with CT scan with contrast administration can, in most cases, confirm the diagnosis and lead to faster surgical intervention. It is crucial to act early on clinical suspicion and not to wait for the development of hard evidence.

We herein report a rare case of mycotic aneurysm of the superior mesenteric artery caused by <i>Klebsiella pneumoniae</i>. A 66-year-old man, a known case of hypertension and aorto-oesophageal fistula with stented aorta in 2010 and 2018, presented to the emergency department multiple times over 2 months with severe postprandial abdominal pain associated with vomiting and fever. On his last presentation, the obtained blood cultures grew ESBL positive <i>K. pneumoniae</i> and a repeated computed tomography (CT) showed a growing aneurysm at the origin of the ileocecal branch of the superior mesenteric artery measuring 17 × 10 mm (the aneurysm was 8 × 7.5 mm in the CT angiography on the previous admission). Extensive workup did not reveal the underlying cause of the mycotic aneurysm, thus we believe the cause to be the infected aortic stent, leading to bacteraemia and vegetations to the mesenteric artery causing the aneurysm. The management plan was placed by a multidisciplinary team consisting of vascular surgeons and infectious disease specialists along with review from a dietician to evaluate the patient’s nutritional status. The patient was started on total parenteral nutrition due to his postprandial pain and on antibiotic therapy according to the infectious disease team’s recommendation. He underwent surgical resection of the mycotic aneurysm, which showed a thrombosed aneurysm in the jejunoileal mesenteric area. The histopathology of the resected tissue demonstrated inflammatory aneurysm of the mesenteric artery. Following the surgery, the patient continued his antibiotic therapy and was discharged on the 13th post-operative day with follow-up appointments in the vascular surgery and infectious disease clinic.

Preservation Of The Spleen

Aneurysms of the splenic artery are the most common visceral aneurysm. A splenomesenteric trunk, which involves the splenic artery arising from the superior mesenteric artery (SMA), is rare and occurs in less than 1% of patients. Thus splenic artery aneurysms (SAAs) with an anomalous origin from the SMA are quite rare. We report our experience with the surgical management of a 2.6-cm aneurysm involving a splenic artery arising from the SMA in a 40-year-old woman. This was treated with surgical resection with preservation of the spleen. A discussion about SAAs and the management of aneurysms arising from a splenomesenteric trunk follows.
