Ablation therapy is a medical procedure that employs either extremely high or low temperatures to eliminate abnormal tissue or tumors and address various medical conditions. This technique is minimally invasive, meaning it doesn’t require open surgery and usually involves removing one or more layers of tissue, as opposed to surgical resection, which removes entire organs or parts of them. For instance, ablation therapy can be used to target and destroy small amounts of heart tissue responsible for irregular heart rhythms or to treat tumors found in different parts of the body, such as the lung, breast, thyroid, liver, and more.
Specialists trained in medical imaging, like radiologists, as well as cardiac specialists (cardiologists), and other healthcare professionals perform ablation therapy. They may employ probes inserted through the skin, flexible catheters introduced via arteries, or energy beams for the procedure. Imaging techniques play a crucial role in guiding the ablation process. Abnormal tissue can be compromised or eliminated using various methods, including heat (radiofrequency ablation), extreme cold (cryoablation), lasers, or chemical agents.
Ablation therapy involves the destruction of abnormal tissue through various methods, including:
Ablation procedures are used to treat various medical conditions, with common examples including:
The risks associated with ablation therapy can vary depending on the specific procedure and the underlying medical condition. Overall, ablation therapy is considered relatively safe, with a low risk of complications. However, potential complications may include:
Ablation therapy offers several advantages over open surgery, including reduced risks, minimal bleeding, and a faster recovery period. During the procedure, patients can remain conscious under local anesthesia, often avoiding the need for open surgery altogether, leading to shorter hospital stays or even same-day discharge. Importantly, ablation therapy preserves healthy surrounding tissue and can be repeated if necessary. Additionally, it can be combined with other treatment modalities such as chemotherapy or medication therapy for a comprehensive approach to patient care.
The procedure can be conducted either in a hospital or an outpatient facility and may involve sedation. Preparation includes shaving and disinfecting the area, followed by the administration of a local anesthetic to numb the needle or catheter insertion site. In some cases, general anesthesia is used, rendering the patient unconscious during the procedure. A needle puncture or small incision is made to facilitate the insertion of the probe or catheter. In catheter ablation, a balloon catheter is typically introduced through a blood vessel, often in the groin, forearm, or neck, and guided to the heart with the assistance of imaging for precise placement. The duration of the procedure varies based on the specific ablation type and medical condition, with catheter ablation typically spanning three to six hours.
The length of your hospital stay after the procedure will depend on the specific type of treatment, with catheter ablation typically requiring an overnight stay. If a local anesthetic was used, you may be able to go home within a few hours, while those who received a general anesthetic might experience nausea. Fatigue can be expected for a few days post-ablation, and discomfort may last anywhere from hours to days, varying depending on the procedure and underlying condition. Strenuous activities should be avoided for a period determined by your doctor, and if discharged the same day, arrange for transportation. Women undergoing endometrial ablation may have vaginal bleeding or discharge for up to three to four weeks. In case of high fever, excessive bleeding, vomiting, severe pain, or any unusual symptoms, seek immediate medical attention.
Ablation procedures may not always provide the desired results or be the optimal treatment choice for a specific condition, potentially requiring continued medication use even if the procedure succeeds. In cases where ablation therapy proves ineffective, alternative procedures may be necessary, and it’s crucial to have a thorough discussion with your doctor about all available options. Additionally, if the condition reoccurs, the ablation procedure might need to be repeated, typically with a waiting period of three to six months following cardiac or catheter ablation to assess its effectiveness.
