Portomesentric and splenic vein thrombosis (PMSVT) after bariatric surgery: a systematic review of 110 patients

PMSVT usually occurs within the first postoperative month and is mostly reported after sleeve gastrectomy. The portal vein is the most commonly involved vessel. A previous hypercoagulable state can be an important risk factor. Most patients can be treated with anticoagulation therapy. Further studies with comprehensive data review of patient information are required.
