Splenic autotransplantation in a patient with human immunodeficiency virus infection: a case report

INTRODUCTION Splenectomy is performed mostly because of traumatic events that cause rupture of the spleen. Postsplenectomy, a patient has a higher risk of developing sepsis. Autotransplantation of splenic tissue decreases the risk of opportunistic infection and sepsis, but its role in patients with human immunodeficiency virus is debated because the spleen is a replication site, especially during the asymptomatic phase of this infection. We present a case of a patient with human immunodeficiency virus infection who was admitted to our hospital for a traumatic rupture of the spleen and underwent spleen autotransplantation. CASE PRESENTATION A 36-year-old Caucasian man was admitted to the shock trauma center of our hospital after a car accident. Anamnesis showed that the patient had been human immunodeficiency virus-positive for 13 years. A computed tomography scan showed abundant fluid collection in his superior and inferior abdomen caused by splenic rupture, with no other associated intra-abdominal lesions. During surgery, the spleen appeared severely damaged. A splenectomy was performed, and 35 g of splenic tissue was autotransplanted in a pouch created in the omentum. No complications occurred after surgery, and our patient was discharged from our hospital nine days after the operation. One year later, computed tomography and scintigraphy showed that the transplanted tissue was functioning well. CONCLUSIONS Autotransplantation of splenic tissue decreases the risk of opportunistic infection and sepsis, and it might also be useful in patients with human immunodeficiency virus. Other studies need to be done to validate this hypothesis.
