Management of True Aneurysms of the Splenic Artery

Background: Splenic artery aneurysms (SAA) are detected with increasing frequency but their management still remains controversial. This paper relates our experience in the outcome and management of ruptured aneurysms of the splenic artery.

Methods: Between 1977 and 1996, 8 patients presented to our institution with a ruptured SAA. Their ages ranged from 25 to 72 years (mean 55 ys).

Results: All patients presented with rupture as the first sign of SAA. One patient was at 32 weeks of gestation and rupture suggested placental abruption. Three patients required cardiopulmonary reanimation prior to surgical procedures. Splenopancreatectomy (n = 4), splenectomy (n = 2), and ligation of the splenic artery (n = 1) were performed. Seven of the 8 patients survived. Size of aneurysms ranged from 2 cm to 3.5 cm (mean 3 cm).

Conclusions: SAA may rupture at any age. Diagnosis during pregnancy rests upon a high index of suspicion. The mortality rate remains low if immediate resuscitation is performed and an aggressive surgical approach is taken.
