<unk>  is the formation of a thrombus in the splenic<unk> . When thrombosis of the splenic<unk>  occurs, collateral vessels develop to shunt blood around the occluded splenic<unk> . The two most common collateral pathways use the short gastric vessels. In the distal esophagus, portosystemic collaterals connect the short gastric<unk> s into the azygous system. There is no established system for classification of<unk> . Common causes of<unk>  are pancreatitis, pancreatic pseudocyst, pancreatic carcinoma, lymphoma, adenopathy from metastatic cancer, iatrogenic causes, splenectomy, partial gastrectomy, distal spleno-renal shunt, factor V Leiden mutation, prothrombin G20210A mutation. The incidence of<unk>  was estimated to be 14,100 cases per 100,000 individuals worldwide.<unk>  affects men and women equally. There is no racial predilection for<unk> . Most patients are asymptomatic, however,<unk>  should be suspected in patients with a history of pancreatitis and  gastrointestinal blood loss, splenomegaly in the absence of portal hypertension, cirrhosis, and hematologic disease, in the setting of isolated gastric varices,  splenomegaly with rare leukopenia, thrombocytopenia, left upper quadrant and abdominal pain. Ultrasound, CT and MRI scans are important diagnostic modalities in the diagnosis of<unk> . Medical therapy for<unk>  include anticoagulation to maintain INR between 2 to 3. The goal of anticoagulation is to prevent extension of the clot and to allow for recanalization. Splenectomy is recommended for all patients with bleeding varices associated with isolated<unk> . Splenectomy eliminates venous collateral outflow and decompresses surrounding varices.
