Background/Introduction

Transarterial chemoembolisation (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor’s blood supply. This type of treatment affects cancer in two ways: first - the chemical substance is delivered in high concentration close to the tumor, without exposing the patient's entire body to the toxic drug effect; second - TACE stops the blood supply to the affected site and the tumor no longer benefit for development of the necessary nutrients and oxygen. At the same time it blocks the chemical...

Description of activity and work performed

The study was conducted at the Pauls Stradins Clinical University hospital, Institute of Diagnostic radiology during the period from November 2012 till April 2013. Since the average radiation dose received during TACE substantially did not change for patients, each study group were selected by 3 patients, which characterizes the general situation, without giving any other criteria of evaluation. To calculate the patient received radiation dose (Gy), the specific formula is used to recalculate the DAP (dose area product) to the absorbed dose. The equivalent dose...

Conclusion and Recommendations

Chemoembolisation for patients with liver lesions is safe procedure with less radiation exposure and does not exceed the threshold dose of radiationin comparison to the intracranial aneurysm embolisation.
