Background: Mesenteric venous thrombus may be an incidental finding during imaging studies and asymptomatic patients are treated conservatively or with anticoagulant therapy only. Patients with symptomatic acute thrombosis causing bowel ischemia require urgent treatment, which frequently includes extensive surgery. Interventional treatment may be an alternative. Purpose: To present results of interventional treatment in patients with symptomatic occlusion of the mesenteric veins. Material and Methods: Eight patients, four men and four women aged 24-74 years (mean 53 years) were treated due to symptomatic portomesenteric venous occlusion of thrombotic origin. Transhepatic (n=5), trans-splenic (n=2), and transjugular (n=4) accesses were used. Patients were treated with mechanical thrombus fragmentation (n=4), pharmacological thrombolysis (n=3) and stent placement (n=8). Additional transjugular intrahepatic portosystemic shunt (TIPS) was created to facilitate the outflow from the treated veins (n=4). Results: The majority of the patients required combination of different treatment methods. Resolution of symptoms with initial clinical success was achieved in seven of the eight patients, and one patient died the day after the procedure due to sepsis. Two other patients had procedure-related complications; one of them required embolization. Two patients had documented long-term clinical success with patent stents and no symptoms at one year following intervention. Conclusions: Endovascular treatment of portomesenteric occlusion in patients with acute symptomatology showed good short-term clinical success rate.
