The effect of the endovascular access on the effectiveness and safety of chemoembolization of the arteries of the liver with unresectable liver metastases

Background. Minimally invasive surgery techniques are widely used in the treatment of primary and metastatic liver cancer. Objective. The goal was to evaluate the effect of the endovascular access on the efficiency and safety of chemoembolization of liver arteries (CELA) in patients with unresectable liver metastases. Methods. In 30 patients with unresectable liver metastases, CELA was performed using the transradial and transfemoral approaches. The microcatheter technique was used for superselective chemoembolization of the liver arteries with introduction of drug-saturated microspheres (HepaSphere). All the digital material was statistically processed using the STATISTICA 6.0 software package (StatSoft, 2001). The results were considered statistically significant at p
