What type of angiography is included in the TACE/SIRT procedure?

The correct choice is based on the fact that Transarterial Chemoembolization (TACE) and Selective Internal Radiation Therapy (SIRT) are procedures primarily targeting hepatic tumors, which means that the relevant regions of interest are typically the hepatic (liver) and portal circulation.

In the context of TACE, the goal is to selectively deliver chemotherapeutic agents directly into the blood supply of the tumor while also occluding the blood flow to achieve an embolic effect. The hepatic arteries play a critical role in this procedure, as the tumors primarily receive their blood supply from the hepatic artery rather than the portal vein.

Furthermore, the celiac trunk gives rise to the hepatic artery, and understanding this anatomical relationship is crucial when performing these interventional techniques. The celiac trunk’s supply includes the common hepatic artery, which leads to both the left and right hepatic arteries that supply the liver directly. Therefore, the decision to focus on the celiac artery and the superior mesenteric artery (SMA) is relevant for understanding blood flow patterns that could impact certain liver lesions during such procedures.

This knowledge of vascular anatomy is essential for interventional radiologists to effectively plan and execute TACE and SIRT, emphasizing the role of the
