[Treatment of celiac trunk aneurysms: personal experience and review of the literature].

Introduction: Celiac trunk aneurysms represent 4% of all splanchnic artery aneurysms. These lesions are thus extremely rare but yet have a significant clinical importance. Mortality, mainly related to site characteristics, is a significant risk (14%) in the event of rupture.

Patients And Methods: We put forward our experience in both diagnosis and treatment in three patients, two women and one man (average age 55.3 years, range 35-74), presenting aneurysms involving the celiac trunk. The preoperative diagnosis was established successively with ultrasonography, CT scan and angiography. Two patients were treated via an open surgical approach while endovascular percutaneous treatment was performed for the third patient.

Results: Mortality was null at 13 days on average from admission for the surgical patients and 4 days for the patient treated endovascularly. Postoperative complications were modest: pulmonary thickening with pleural effusion for the two surgical patients (spontaneous resolution), while for the third patient treated with an endovascular method, the stent migrated to a splanchnic arterial branch, with no consequence for the spleen. The average follow-up was 19 months (range 14-24). Full exclusion of the aneurysm was maintained at four months for the aneurysm treated percutaneously. A patent celiac was also maintained for the patients treated surgically.

Conclusions: Considering the largely unforeseeable outcome and the high risk of rupture, we suggest that all the patients presenting this type of aneurysmal lesion should be treated. This attitude is widely advocated in the literature. Moreover, we noted null mortality in our small series, with only one percutaneous "re-do" case; resolutive at last control. With the present improvement in stent technology, endovascular treatment should be preferred. Patients should be treated surgically only if a percutaneous procedure would be risky or technically unfeasible due to the size of the aneurysm or its anatomic features.
