Helical Computed Tomography in the Diagnosis of Portal Vein Invasion by Pancreatic Head Carcinoma

Helical computed tomography in the diagnosis of portal vein invasion by pancreatic head carcinoma: usefulness for selecting surgical procedures and predicting the outcome.

OBJECTIVE To evaluate the use of helical computed tomography (CT) in diagnosing portal vein (PV) invasion by pancreatic head carcinoma and its usefulness in predicting outcome. DESIGN Validation cohort study. SETTING Tertiary care public hospital. PATIENTS Twenty-seven patients with carcinoma involving the pancreatic head were preoperatively studied with helical CT. All patients underwent...

the predictive value of computed tomography in jugular vein by head and neck tumors

abstract: introduction & objective: awareness of invasion of the walls of the cervical vessels by tumor is of great clinical importance before surgery. this study was designed to assess the diagnostic worth of computed tomography (ct) in distinguishing jugular vein (jv) invasion by oral –maxillofascial and neck malignant tumors. material & methods: ct with contrast was performed on 46 patients ...

Vasculogenic mimicry in hepatocellular carcinoma contributes to portal vein invasion

Portal vein invasion (PVI) is common in hepatocellular carcinoma (HCC) and largely contributes to tumor recurrence after radical tumor resection or liver transplantation. Vasculogenic mimicry (VM) was an independent vascular system lined with tumor cells and associated with poor prognosis of HCC. The present study was conducted to evaluate the relationship between VM and portal vein invasion. A...

Spiral computed tomography for preoperative staging of potentially resectable carcinoma of the pancreatic head.

BACKGROUND Pancreatic cancer is often locally invasive. Preoperative staging attempts to identify patients suitable for resection, in order to minimize unnecessary operations. The aim of this study was to assess the improved imaging provided by spiral computed tomography (CT) in the preoperative staging of potentially resectable pancreatic head carcinoma. METHODS In 56 consecutive patients wi...
