Portal and superior mesenteric venous thrombosis treated with thrombolytic therapy via the superior mesenteric artery and vein.

A 61-year-old man was hospitalized for treatment of portal and superior mesenteric venous thrombosis (PSMVT). We selected interventional radiology (IVR) because there were no signs of intestinal necrosis. The thrombosis was significantly reduced and the patient made progress after we performed thrombectomy via catheter aspiration, and thrombolytic therapy via both the superior mesenteric artery and vein. Even if there are no signs of intestinal necrosis, treatment which prevents intestinal necrosis is vital. In the present case, single-stage IVR therapy via both the superior mesenteric artery and vein improved the therapeutic outcome of PSMVT.
