Objective: To describe our experience with the management of aneurysms
of the splanchnic arteries. Design: Retrospective study. Setting: Tea
ching hospital, Norway. Subjects: Eleven consecutive patients with ane
urysms of the splanchnic arteries treated between 1986 and 1996, six o
f them between 1994 and 1996. Four aneurysms were hepatic (37%), two s
plenic (18%), one coeliac (9%), one gastroepiploic (9%), one pancreati
coduodenal (9%), one superior mesenteric (9%), and one jejunal (9%). F
ive were pseudoaneurysms (46%). Interventions: Six patients (55%) were
treated by operation, four (36%) by embolisation and one (9%) expecta
ntly. Results: The pathogenesis was inflammatory (acute pancreatitis,
anastomotic leak) in four patients (36%), athero-sclerotic in three (2
7%), arterial infusion of cytotoxic drugs in one (9%), and unknown in
four (36%). Seven patients (64%) presented with rupture, two (18%) wit
h other symptoms, and two patients (18%) were diagnosed incidentally.
There was no mortality. Conclusion: There may be an increased incidenc
e in splanchnic artery aneurysms, particularly those created by inflam
matory lesions. The diagnosis should be suspected if acute bleeding oc
curs during the course of severe intra-abdominal inflammation. Arterio
graphy should be used to diagnose an aneurysm in haemodynamically stab
le patients. Control of bleeding is obtained either by transarterial c
atheter embolisation or by operation.
