To deliver therapeutic material to tumors during trans-arterial chemoembolization therapy, it is essential to identify the liver vessels accurately. But the liver’s complex vasculature can make precise identification of tumor-feeding vessels in 2D and 3D images a challenge, often requiring significant time, radiation, and contrast media.
Performing needle procedures in the interventional suite frees up your CT system and provides better access to the patient. However, under fluoroscopic guidance, it may be challenging and time-consuming to find the right entry point and advance the needle while avoiding critical structures.
Portal Vein Embolization
The objective is to embolize only the branches that correspond to the part of the liver that will be resected. The portal vein has numerous anatomical variations, with many different branches that can be difficult to distinguish one from another on 2D fluoroscopic images. To do this with confidence, you must understand the exact position of the catheter in the anatomy and control the embolization phase in real time.
