Thrombosis of the portal system is a potentially life-threatening but otherwise underappreciated complication after splenectomy. Nonspecific and mild onset symptoms are the cause of delay in diagnosis, and the short hospital stay after laparoscopic approach could even contribute to the difficulty of early detection of this condition. The aim of this study was to verify if planned imaging controls are able to discover this complication leading to a prompt treatment. Thirty-eight patients (19 males and 19 females with a mean age of 24 years) who underwent laparoscopic splenectomy at our institution were studied to identify clinical signs of thrombosis of the portal venous system and eventually associated factors. All the patients were enrolled in a protocol of imaging surveillance using a doppler ultrasound method. Postoperative thrombosis of the spleno-portal axis occurred in 7 patients (18.9%) of the series. In 3 cases (8.1%) the thrombus extended from the splenic vein to occlude the portal axis. The complication was symptomatic in 4 cases (10.8%), whereas in 3 cases, the thrombosis was an ultrasonographic surprise in totally asymptomatic patients. Thrombosis occurred even as late as 2 months after splenectomy. Splenomegaly was the only significant factor predictive of thrombosis. Only those patients who had an early detection of portal or splenic vein thrombosis had a recanalization of the veins with anticoagulant therapy. Patients with splenomegaly who underwent laparoscopic splenectomy are at risk of thrombosis of the portal system and should undergo strict imaging surveillance and aggressive anticoagulation therapy.
