Aim. The purpose of this study was to review the management of celiac artery aneurysms and propose a new classification.
Methods. Five patients operated upon at a tertiary vascular centre, represent the basis of our experience. Reports of celiac artery aneurysms were identified through a Medline search (1966-December 2000).
Results. 192 cases were identified. The mean age of the patients was 51±12 years, 66% of them were males, 38% asymptomatic, of the one which were symptomatic 60% had gastrointestinal symptoms. Twelve percent of aneurysms presented with rupture. Size ranged from 1 to 10 cm (mean, 4±1.5). Aneurysms of other arteries were present in 42 patients (41%), 8 had more than one aneurysm in other arteries. Aetiology was atherosclerosis in 54%, fibromuscular dysplasia 12%, infection 6%, congenital anomalies 4%, medial degeneration and trauma 3%, and aortic dissection 1%. Excision of the aneurysm without reconstruction was performed in 31% of patients, excision with revascularization in 65% (end-to-end repair 53%, and interposition graft 47%). Perioperative mortality was 9% for elective, and 43% for the ruptured aneurysms . In our series the aneurysm size ranged from 3-4 cm. All patients survived surgery, one died of myocardial infarction 3 years after surgery, and the others are alive at 77±39 months.
Conclusions. Celiac artery aneurysms are uncommon. Surgery is indicated for a diameter ? 3. We propose a classification based on the prevalent involvement of the origin, body or trifurcation of the celiac artery: Type I, and large type II aneurysms may be repaired through a retroperitoneal low thoracoabdominal incision, and type II of small size and type III, with a transabdominal approach.
