Abstract
Portal vein thrombosis is a major complication of splenectomy. Its frequency is underestimated because of asymptomatic cases. Mesenteric occlusion with intestinal infarcts is the first cause of mortality. Secondarily, in the absence of repermeabilisation, a portal hypertension can occur. We present in this study 4 cases of portal vein thrombosis in childhood. Portal vein thrombosis is frequent (8% of splenectomies) and may be asymptomatic. Doppler postoperative surveillance is justified. Thrombocytosis seems to be a determinant factor. Early diagnosis and treatment may reduce lethal outcome.
