5f rh catheters

As reported previously (12 (link)), all TACE procedures were performed by at least two experienced interventional radiologists, and TACE was performed through the traditional femoral artery approach under local anesthesia. 5F RH catheters (Terumo, Tokyo, Japan) were first used for routine angiography, and then microcatheters (Terumo, Tokyo, Japan) were used for super selective arterial catheterization to enter the blood supply branch of the tumor. A mixed solution containing lipiodol (Laboratories Guerbet, Paris, France) and doxorubicin (Haizheng Pharmaceutical, Taizhou, China) was administered into the tumor-feeding vessels, followed by the injection of gelatin sponge particles (500 mm-700 mm; ALICON Dr. SCI&TEC Co., Ltd., Hangzhou, China) to supplement embolization until blood flow nearly ceased. The dose of doxorubicin was 50-70 mg and that of lipiodol was 5-20 ml; the specific dose should be adjusted according to the patient’s tumor number and size, liver function, blood vessel distribution, and body surface area.

As reported previously, the TACE procedure remained consistent across the centers (12 (link)). All TACE procedures were performed by at least two experienced interventional radiologists using the traditional femoral artery approach under local anesthesia. 5F RH catheters (Terumo, Tokyo, Japan) were first used for routine angiography, and then microcatheters (Terumo) were used for super-selective arterial catheterization to enter the blood supply branch of the tumor. A mixed solution containing lipiodol (Laboratoire Guerbet, Paris, France) and doxorubicin (Haizheng Pharmaceutical, Taizhou, China) was injected into the tumor-feeding vessels, followed by injection with gelatin sponge particles of 500–700 µm (ALICON Pharmaceutical, Hangzhou, China) to supplement embolization until the blood flow nearly ceased. The dose of doxorubicin was 50–70 mg, while that of lipiodol was 5–20 mL. The individualized doses were adjusted according to the patient’s tumor number and size, liver function, blood vessel distribution, and body surface area.
