The spleen can be removed. The main indications for splenectomy are traumatic splenic rupture, portal hypertension combined with hypersplenism, splenic cysts, ectopic spleens, tumors, cysts, and some hematopoietic disorders such as primary thrombocytopenic purpura, congenital hemolytic anemia, and aplastic anemia. Complications that are likely to occur in the immediate post-splenectomy period include hemorrhage, pulmonary or subdiaphragmatic infection, and thrombo-embolism. Since the spleen is the largest peripheral lymphatic organ and autoimmunity is weakened after resection, a late complication is a postoperative aggressive infection characterized by rapid onset and progression. Partial splenectomy or partial splenic artery embolization when your condition permits can effectively reduce the chance of complications. If there is any discomfort, seek medical attention promptly.
