Endovascular Treatment of Aberrant Splenic Artery Aneurysm Presenting With Painless Progressive Jaundice: A Case Report and Literature Review

Splenic artery (SA) originating from the superior mesenteric artery is a rare condition, and aneurysms in relation to this aberrant SA are even rarer. We reported the case of a 67-year-old female who presented with painless progressive jaundice for 2 months accompanied by thrombocytopenia and liver dysfunction. The computed tomographic angiography (CTA) showed an aberrant SAA located behind the pancreatic head along with the dilation of common bile duct. Stent-graft deployment in SMA and coil embolization of the aneurysm were performed. Her liver dysfunction and thrombocytopenia improved postoperatively. CTA at 2-year follow-up showed patency of stent-graft and SMA and the shrinkage of the excluded aneurysm sac. Considering the particular location of the aneurysm, painless progressive jaundice can be the initial symptom for the aberrant SAAs. This combined endovascular technique completely excluded the aneurysm and was beneficial for treating secondary liver dysfunction and thrombocytopenia.
