Multi-Detector CT Angiography With 3D Reconstruction Versus Digital Subtraction Angiography

Multiphasic CT within 4 weeks interval prior to TACE will be done including non-enhanced, arterial, portal and venous phases using IV bolus injection of a 75-100-mLiodinated contrast material iopamidol at a rate of 3.0 mL/s. The images of arterial phase will be transferred to workstation to produce 3D angiographic reconstruction images .

Percutaneous arterial access is achieved through the common femoral artery (19 G needle) under local anesthesia with placement of a 5-Fr sheath. A 5-Fr Cobra (C2) or sidewinder (SIM1) catheter was used for catheterizing the coeliac trunk and SMA. Then celiac and superior mesenteric angiography was done by injecting 24 mL of iopamidol using forced manual injection method or using a pump at a rate of 6 mL/s according to the operator preferences.Then a microcatheter was used for selective and super-selective access of the hepatic arteries. The micro-catheter was placed in the feeding artery as close as possible to the tumor.The chemotherapeutic drugs (Doxorubicin 50 mg) solved within 5 ml of iodinated non-ionic contrast media and then mixed with 10 ml of iodized oil (lipiodol) will be delivered through the feeding hepatic artery and then embolized using Poly-vinyl Alcohol (PVA) particles.
