Transcatheter arterial chemoembolizations currently recognized as one of the most common methods for non-operative treatment of liver cancer. Drug eluting beads (DEBs) have been imposed as novel drug delivering agents for TACE, which allows for higher concentrations of drugs within the target tumor and lower systemic concentrations compared with c-TACE.
An 83-year-old male was diagnosed with primary liver cancer. MRI examination revealed a tumor in the right lobe of the liver with a maximum diameter of 42 mm. The patient cannot tolerate surgery at an advanced age, so hepatic arterial chemoembolization was performed to prolong the patient’s life. Intraoperative deb embolization was applied. At the same time, 3D-CT was used to identify the blood vessels of liver cancer and embolizes lymph node metastasis.
Described in this video is one of the hepatocellular carcinoma patients with retroperitoneal lymph node metastasis (Figure 1). The patients were given local anesthesia with 5 mL of 2% Lidocaine. The puncture of right common femoral artery was performed with a 5.0-Fr micro-puncture introducer set by using the Seldinger technique. The celiac trunk was catheterized with a 4.0-Fr RH catheter and the angiographies were completed (Figure 2). Then, the micro-catheter was introduced to the hepatic arteries and advanced further into segmental arteries by using selective catheterization (Figure 3). DEB was slowly injected into the feeding arteries through the catheter until the tumor-feeding branches were near stasis (Figure 4) after the CT can be found in local tumor necrosis. Lymph node arteries were found by angiography (Figure 5), then chemoembolization was performed (Figure 6).
Transcatheter arterial chemoembolizations currently recognized as one of the most common methods for non-operative treatment of liver cancer (2). DEBs have been imposed as novel drug delivering agents for TACE, which allows for higher concentrations of drugs within the target tumor and lower systemic concentrations compared with c-TACE. Transarterial chemoembolization for hepatocellular carcinoma can control the tumor growth, but not completely cured (3,4).
The use of CT is rapidly being replaced by multidetector CT to facilitate easier visualization of the anatomy using 3D images. 3DCT simulation can facilitate the precise identification of these vasculatures pre- and intra-operatively (5,6).
There are limited studies to investigate TACE therapy for lymph node metastases in HCC. Therefore, little is known about its efficacy and side effects. Wu et al. verified the efficacy and safety of arterial chemoembolization for lymph node metastasis (7).
The history of this case is that elderly male hepatic artery chemoembolization prolongs the patient’s life. In order to improve the accuracy of embolization, 3D-CT was used to identify tumor blood vessels. Liver cancer and lymph node metastasis were embolized respectively. False embolization may lead to pancreatitis and other complications, especially when embolization lymph node metastasis. Repeated selection of tumor vessels during surgery requires patience. Complete the operation with an artist’s heart, so that better results can be achieved through intervention.
