  • Title: Accessory spleen compromising response to splenectomy for idiopathic thrombocytopenic purpura.
    Author: Ambriz P, Muñóz R, Quintanar E, Sigler L, Avilés A, Pizzuto J.
    Journal: Radiology; 1985 Jun; 155(3):793-6. PubMed ID: 4039827.
    Abstract:
    Accessory spleens were sought in 28 patients who had undergone splenectomy for chronic idiopathic thrombocytopenic purpura (ITP), using a variety of techniques. Abdominal scintigraphy with autologous erythrocytes labeled with Tc-99m and opsonized with anti-D IgG (radioimmune method) proved to be most useful, clearly demonstrating one or more accessory spleens in 12 cases (43%). Computed tomography (CT) was also helpful. Four out of five patients demonstrated an increased platelet count following surgery, the effectiveness of which was illustrated by the radioimmune scan. Patients who have had splenectomy for chronic ITP should be scanned using radioimmune techniques and CT to determine whether an accessory spleen is present.
