Abstract

The purpose of the study was to evaluate CT criteria for venous invasion in patients with potentially resectable carcinoma of the pancreatic head, with surgical and histopathological correlation. In 113 patients evaluated with spiral CT for suspected pancreatic head carcinoma, several CT criteria for venous invasion were scored prospectively for the portal vein (PV) and the superior mesenteric vein (SMV): length of tumour contact with PV/SMV (0 mm, <5 mm, >5 mm); circumferential involvement of the vein (0 degrees, 0-90degrees, 90-180 degrees, >180 degrees); degree of stenosis; irregularity of the vessel margin; and tumour convexity towards vessel. 65 patients underwent surgery. Pancreatic head carcinoma was proven and pathology of the vascular margin was obtained in 50 of these patients. CT findings for single and combined criteria were correlated with pathology in these 50 patients, 30 of whom showed venous ingrowth. Invasion was found in all cases with SMV narrowing (n=7), PV contour involvement>90 degrees (n=6), PV narrowing (n=5) and PV wall irregularity (n=3). The vascular ingrowth rate was 88% (15/17) for tumour concavity towards the PV or SMV. Poor predictors of ingrowth were length of tumour contact with PV>5 mm (78% ingrowth, 14/18) and contourinvolvement of the SMV>90 degrees (83% ingrowth, 10/ 12). Absence of vascular ingrowth could not be predicted in 100%. In conclusion, CT criteria canpredict a high risk of invasion in potentially resectable tumours. Narrowing of the SMV and the PV seems the most reliable criterion, as well as circumferential involvement of the PV,90 degrees. The best combination of criteria was tumour concavity with circumferential involvement>90 degrees (sensitivity 60% and positive predictive value 90%).
