Nexaris Angio-CT Embolization Ablation Use Case Video
This video illustrates how the nexaris Angio-CT system combination enables providers to perform liver embolization and microwave ablation in a single procedure to treat a patient with liver cancer.
The next terrace, angio CT is an integrated multi modality imaging therapy suite designed to advance therapy outcomes. With quick switch and instant Fusion, the customized solution has the ability to streamline interventional oncology procedures. This video will take a closer look at a patient with liver cancer. Traditionally, liver embolization and microwave ablation have been separate procedures performed on different days. The first hospital visit for the Angio guided embolization would require the patient to be sedated and stay at the hospital. The patient would then have to return to the hospital for a second stay and be sedated again to have the CT guided ablation procedure performed. Now with the next serious Angio CT system combination, it is possible for liver embolization and microwave ablation to be reduced into one procedure that is performed on the same day. Angio CT guided EMBO ablation only requires one hospital visit, one time being sedated and one hospital stay for patient recovery. Let's take a look at an overview of all the steps involved in the EMBO ablation case. First, the catheter is put in the celiac trunk under fluoro guidance. Then the patient is switched to the CT system to get an intra arterial CT angiography. This CT data set is then used to identify which arteries are the feeder arteries automatically with embolization guidance on the angio workstation. Meanwhile, the patient is switched to angio again. The feeder vessels are then fused or overlaid on the live fluoro for vascular guidance during the embolization. Finally, the patient is switched back to the CT scanner for the 3D guided ablation under CT. Now let's go back and take a closer look at each step. Initially doctors start with the conventional angiogram of the hepatic artery. However, the tumor tends to be poorly visible on the 2D DSA. In preparation for the CT image, a catheter is placed in the hepatic artery and contrast is injected for the see T angiogram. Oftentimes the doctor's main question is, how do I get to the tumor, and how do I treat it? The CT image can be used to help answer this question and help define which vessel leads to the tumor. Next, Access Path planning is possible with syngo embolization guidance and based on the information acquired from the CT scan. Access Path planning is a helpful step in planning how to reach the tumor feeding vessel. Without the results of the CT scan, the hepatic artery is nearly impossible to determine, but thanks to the CT exam, the doctor is capable of determining which vessel is supplying the tumor with blood flow. Using a 3D road map, overlap on live fluoroscopy and the see T angiogram to confirm the catheter position. Doctors can inject the chemotherapy drug with eluting beads. By switching from angio to CT, the result of the embolization can be checked immediately. After confirmed success, a 3D guided interventional ablation can be performed to destroy the tumor without the risk of a bleeding organ. The immediate CT scan following the insertion of the chemotherapy drug is made possible by the quick switching feature of the next terrace Angio CT system combination. Quick switching enables patients to remain on the same table while you switch quickly between operating angio and CT systems. This video illustrates how the quick switching feature enables the patient table and CT sliding gantry to move into the necessary scan position immediately following the NGO scan and then return to the NGO working position. Additionally, Artis with pure enables easy interplay between the angio and CT systems. The instant Fusion feature allows for reliable Rd mapping and embolization guidance.
