OBJECTIVE: Splenectomy influences the Doppler blood flow pattern in the splenic artery. Blood flow in this vessel might return to normal if an accessory spleen increases in size after splenectomy. Our objective was to evaluate the resistive index of the splenic artery depending on the presence or absence of a hypertrophic accessory spleen in splenectomized patients. METHODS: The resistive index of the splenic artery was evaluated by duplex Doppler sonography in 19 splenectomized patients (8 with a hypertrophic accessory spleen) and in 8 healthy volunteers. The resistive index was measured within 3 cm of the origin of the splenic artery, and 3 different measurements were averaged. The presence or absence of a hypertrophic accessory spleen was diagnosed on the basis of sonography, computed tomography, magnetic resonance imaging, or scintigraphy, as well as by the presence or absence of Howell-Jolly bodies on a peripheral blood smear. RESULTS: The resistive index of the splenic artery in the splenectomized patients without a hypertrophic accessory spleen (mean +/- SD, 0.82 +/- 0.06; n = 11) was significantly (P < or = .0001) higher than in splenectomized patients with a hypertrophic accessory spleen (0.63 +/- 0.06; n = 8) and in control subjects (0.63 +/- 0.05; n = 8). CONCLUSIONS: In the splenectomized patient, a hypertrophic accessory spleen is associated with a normal resistive index in the splenic artery. |
