Portal/splenic Vein Thrombosis Following Splenectomy in Gastric Cancer Surgery

Abstract

Although splenectomy is often performed along with en bloc node dissection in gastric cancer surgery, portal/splenic vein thrombosis (PSVT) has been rarely reported. We recently encountered a case of PSVT after a splenectomy was performed during gastric cancer surgery. A 53-year-old woman underwent total gastrectomy, splenectomy, and en bloc regional lymph node dissection for gastric cancer. An uneventful postoperative course ended with abrupt development of a fever and general fatigue. Laboratory tests showed elevated levels of liver transaminases and fibrinogen degenerative products. Contrast-enhanced computed tomography revealed splenic vein thrombosis and partial liver infarction. Immediate anticoagulant treatment resulted in clinical improvement and partial thrombolysis in 2 months. PSVT after splenectomy in haematological disorders has been recognized as a possibly lethal complication. However, it has been underappreciated in cases of splenectomy for gastric cancer. The present case demonstrates the importance of considering PSVT as a possible complication of splenectomy in gastric cancer surgery.
