INTRODUCTION: Portal vein thrombosis is an unfrequent, but potentially deadly, complication of the laparoscopic splenectomy procedure. The laparoscopic approach has shortened the duration of hospital stay; portal vein thrombosis may appear after the patient has left the hospital, determining a later diagnosis. Because of the mild, nonspecific symptoms, the diagnosis can even be missed and only achieved when chronic complications take place.
OBJECTIVES: In this study, we aimed to determine the appearance of portal vein thrombosis in a consecutive series of patients who underwent laparoscopic splenectomy by performing a contrast-enhanced computed tomography (CT) scan postoperatively.
MATERIALS AND METHODS: A transversal study was established, performing in 2005 a contrast-enhanced CT scan on 20 patients who underwent laparoscopic splenectomy between 1999 and 2005 at Ramón y Cajal University Hospital (Madrid, Spain). The presence of thrombosis in the splenoportomesenteric axis was investigated.
RESULTS: Two (2) cases (10%) of portal vein thrombosis were detected: 1 symptomatic case, 7 days after surgery, was treated with anticoagulation, resulting in the disappearance of the thrombus in a new CT scan 6 months later; the second case was asymptomatic and was discovered during the performance of this study.
CONCLUSIONS: The contrast-enhanced CT scan shows the best accuracy for the diagnosis of portal vein thrombosis, and it must be performed when any clinical manifestation appear; also, it must still be determined if a contrast-enhanced CT scan should be systematically performed in high-risk thromboembolic patients. An ultrasound Doppler may present many diagnostic errors. It is probably advisable to prolong the antithromboembolic prophylaxis.
