FIELD: medicine, surgery.
SUBSTANCE: after circular resection of superior mesenteric vein as a single block with pancreatoduodenal complex it is necessary to fulfill its reconstruction. Moreover, one should form direct anastomosis between the stump of superior mesenteric vein and that of splenic vein. Splenic vein should be pre-mobilized from posterior pancreatic surface for the length being sufficient to substitute the defect of superior mesenteric vein. At the border of mobilization splenic vein should be intersected and descended. The stump of superior mesenteric vein in area of portal vein mouth and inferior mesenteric vein should be ligated. The innovation suggested enables to fulfill adequate reconstruction of superior mesenteric vein after its vast resection, exclude the chance for the development of thrombotic complications induced with sampling autovenous conduit out of iliac vein, exclude the chance of unbalance in the transplant's and stump's diameters of the resected vein.
EFFECT: higher efficiency.
