Transileocolic endovascular treatment by a hybrid approach for severe acute portal vein thrombosis with bowel necrosis: Two case reports

BACKGROUND Acute portal vein thrombosis (PVT) with bowel necrosis is a fatal condition with a 50%-75% mortality rate. This report describes the successful endovascular treatment (EVT) of two patients with severe PVT. CASE SUMMARY The first patient was a 22-year-old man who presented with abdominal pain lasting, 3 d. The second patient was a 48-year-old man who presented with acute abdominal pain. Following contrast-enhanced computed tomography, both patients were diagnosed with massive PVT extending to the splenic and superior mesenteric veins. Hybrid treatment (simultaneous necrotic bowel resection and EVT) was performed in a hybrid operating room (OR). EVTs, including aspiration thrombectomy, catheter-directed thrombolysis (CDT), and continuous CDT, were performed via the ileocolic vein under laparotomy. The portal veins were patent 4 and 6 mo posttreatment in the 22 year old and 48-year-old patients, respectively. CONCLUSION Hybrid necrotic bowel resection and transileocolic EVT performed in a hybrid OR is effective and safe.
