Although splenic artery pseudoaneuryms (SAPA) are rare cause of acute abdomen, when they rupture they have high mortality rates. Posttraumatic splenic artery injury and/or active bleeding have also high mortality rates and they require immediate treatment. In our study we aim to discuss the endovascular treatment option for SAPA with our experience and literature.
Materials and Methods: Between 2002-2016 there were 9 patients (6 male,3 female) who had endovascular treatment for SAPA diagnosed with abdominal CT. Endovascular treatment options were platinum coil embolization (n=8) or covered stent implantation (n=1).
Results: Mean age for 9 patients (6 male, 3 female) was 44.8 (in the range between 23-66 years). The only clinical symptom was massive gastrointestinal bleeding (9 patients). Etiologies for SAPAs were; trauma (n=5), iatrogenic (n=2) and acute pancreatitis (n=2). From CT scans and angio images there were pseudoaneurysms (PA) (n=9) and in one patient there were both PA and splenic arterio-venous fistula (AVF) between splenic artery and vein. Seven patients were treated with splenic artery embolization [parent artery occlusion (PAO)]. Other two patients with PA were treated with PA coiling and covered stent implantation. After treatment, results were good and in follow-up period (1-14 months) no complications were occured.
Conclusion: Splenic artery injury is rare cause of acute abdomen with high mortality rate, and it can be treated safely with endovascular technics with good results.
