Résumé
To determine the feasibility and safety of separating close adhesion between the portal vein, superior mesenteric vein (SMV) and pancreas after combined vascular occlusion was employed. Methods: By means of occluding SMV below the pancreata, splenic arteries and veins posterior to the pancreata and portal veins superior to the pancreata consecutively, adhesion between SMV, portal vein and the head of lump pancreatitis, which is hard to deal with by fingers, was separated in 3 cases. Results: During separating procedures, 4～7 sites on portal veins and SMV were injured, with a small amount of hemorrhage (57ml, 81ml and 102ml, respectively), and were easilyrepaired. The vascular blocking time of the 3 cases was 36, 39 and 39.5 minutes. The following whipple procedures were smoothly fulfilled and all 3 patients recovered well. Conclusion: Blood flow of portal vein and SMV and traumatic hemorrhage can be radically controlled by the method of vascular occlusion, which was proved safe, performable and could be a protective method with great effect in separating close adhesion between pancreas and portal and SMV.
