“We included 33 case series of 523 splenic artery aneurysms treated with an endovascular approach and 22 series of 252 splenic artery aneurysms treated with open surgery. Short-term and long-term mortality rates were very low and not significantly different between the two interventions. Mortality was high for ruptured aneurysms treated with an open approach, with an event rate of 0.29 (95% CI, 0.04-0.71). End-organ infarction and gastrointestinal complications rates were not significantly different between the two approaches. The need for reintervention was lower for open surgery 0.00 (95% CI, 0.00-0.11) than for the endovascular approach 0.07 (95% CI, 0.01-0.17). The risk of access site complications for the endovascular approach was low at 0.02 (95% CI, 0.00-0.09). Rates of PES and coil migration were 0.38 (95% CI, 0.04-0.79) and 0.08 (95% CI, 0.00-0.24), respectively. Data were insufficient to identify a difference in mortality based on aneurysm size.”
