What Is Chemoembolization?

Chemical embolization of lung cancer is an interventional treatment method in which microcapsules or microspheres carrying anticancer drugs are delivered to the diseased site through the blood-supplying arteries of the lung cancer to embolize the supplying arteries of the cancer and gradually release anticancer drugs to surrounding tissues. It has the advantages of increasing the drug concentration at the lesion site, and occluding the supply vessels of the lesion, and has the dual effects of hemostasis and chemotherapy.

Chemoembolization for lung cancer

Chemoembolization for lung cancer is mainly applicable to patients with massive hemoptysis of lung cancer.

1. There are contraindications for general vascular intubation and the use of contrast agents.

2. Patients with severe heart, liver and kidney dysfunction and intolerance to chemotherapy.

The purpose and method of the technique should be properly explained to the patient before surgery to obtain patient cooperation. Blood routine, liver, kidney function, flow, clotting time, electrocardiogram, chest radiograph should be routinely checked.

During the treatment, bronchial angiography was performed first. After confirming the anastomosis of the intercostal artery and the spinal artery, the catheter was inserted into the deep part of the bronchial artery and fixed about 2 cm. , Slowly injected under perspective. Prevent drug backflow during injection. Closely observe the patient's breathing, pulse, and limb function during the injection. After the embolization treatment was completed, the tube was bandaged. 500 ml of low-molecular dextran, 10 mg of dexamethasone, and 100 mg of nicotinamide were given intravenously after surgery.

The complications and preventive measures of bronchial artery chemoembolization are basically the same as those of bronchial artery infusion chemotherapy. In addition, the slow injection of medicine during operation to avoid reflux is very important to prevent ectopic embolism and damage to the spinal cord.
