Resection of the main trunk of the superior mesenteric vein without reconstruction during surgery for giant pancreatic mucinous cystadenoma: A case report

Figure 1 Preoperative computed tomography scan. A: Abdominal contrast-enhanced computed tomography (CT) showed a cystic tumor in the body-tail of the pancreas; B: Coronal multiplanar reformation showed that the lesion was adhered to and constricted the main trunk of the superior mesenteric vein; C: 3-dimensional CT scan showed the presence of several well-developed collateral vessels.
