PROCEDURE: Microwave ablation of liver tumor with CT and Ultrasound guidance
MEDICATION:
MICROWAVE ANTENNA: Neuwave
COMPLICATIONS:
PROCEDURE:
Informed consent was obtained and placed in the patient’s chart after the risk of infection, bleeding and liver injury were explained.
Constant physiologic monitoring and moderate sedation were performed by radiology nursing staff. A timeout was performed.
With the patient in the position, the right upper quadrant was scrubbed and draped in the usual aseptic manner. Under CT and ultrasound guidance, a ____microwave antenna was advanced through the center of the tumor and the tip was positioned at its margin. Microwave ablation was performed for 12 minutes. The tract was then sequential ablated as the probe was being removed. The patient tolerated this procedure well and was transferred to the recovery room in stable condition.
IMPRESSION: Successful CT-guided microwave ablation of liver tumor.
Frequently Asked Questions
What is CT/US guided microwave ablation of a liver tumor?
CT/US guided microwave ablation is a minimally invasive procedure used to treat liver tumors. It involves using CT (computed tomography) and ultrasound imaging to accurately place a microwave antenna into the tumor. The microwave energy generates heat, destroying the cancerous tissue. This technique is often chosen for patients who are not candidates for surgery.
How is a microwave antenna used in liver tumor ablation?
In liver tumor ablation, a microwave antenna is inserted through the skin and guided to the center of the tumor using imaging techniques like CT and ultrasound. Once in position, the antenna emits microwave energy, creating heat that destroys the tumor cells. The antenna is then carefully withdrawn, and the path it took is also treated to prevent tumor recurrence.
What are the potential complications of liver tumor ablation?
Potential complications of liver tumor ablation include infection, bleeding, and liver injury. These risks are mitigated by using sterile techniques and precise imaging guidance. Patients are closely monitored during and after the procedure to ensure any complications are promptly addressed.
How do doctors prepare for a liver tumor ablation procedure?
Preparation for liver tumor ablation involves obtaining informed consent and explaining potential risks to the patient. The surgical area is scrubbed and draped aseptically. The patient is placed under moderate sedation, and a timeout is performed to confirm details before proceeding. Imaging guidance ensures accurate placement of the microwave antenna into the tumor.
What is the role of imaging in liver ablation procedures?
Imaging, specifically CT and ultrasound, plays a crucial role in liver ablation procedures by providing real-time guidance for the placement of the microwave antenna. This ensures that the antenna is accurately positioned within the tumor to maximize treatment efficacy while minimizing damage to surrounding healthy tissue.
Why might a patient choose microwave ablation over surgery?
Microwave ablation is often chosen over surgery for patients who are not surgical candidates due to health conditions or tumor location. It's less invasive, has a shorter recovery time, and can be performed with moderate sedation rather than general anesthesia, making it a safer option for some patients.
What happens after a liver tumor ablation procedure?
After liver tumor ablation, the patient is transferred to a recovery room for monitoring until they stabilize. Vital signs are checked frequently to ensure there are no immediate complications like bleeding or infection. Patients typically experience minimal discomfort and can return to normal activities relatively quickly compared to traditional surgery.
How long does a microwave ablation procedure take?
The microwave ablation procedure itself generally takes about 12 minutes to perform. However, the total time spent in the procedure room may be longer due to preparation, positioning, and post-procedure monitoring. Patients can usually return home the same day, depending on their recovery.
