Laparoscopic splenic artery aneurysmectomy with ICG guided partial splenectomy: alternative approach

We herein report the case of a voluminous splenic artery aneurysm (SAA) diagnosed in a 48 year-old Caucasian male patient. After endovascular treatment failure, considering the volumetric aneurysm increase and recurrent symptoms, a laparoscopic splenic artery aneurysmectomy with partial splenectomy guided by indocyanine green fluorescence (ICG) was performed. This conservative strategy leads to save a spleen volume of about 10 cm3 to avoid postsplenectomy thrombocytosis and infections, potential immunodeficiency and overwhelming postsplenectomy infection syndrome (OPSS) and to preserve pancreatic vascularization preventing distal pancreas injuries.
