Do you know how embolization can precisely block the blood flow to the tumor, leaving cancer cells nowhere to escape?
Embodiment is a medical technique that intentionally blocks blood vessels in a certain area to treat a variety of diseases. Its application in cancer treatment is gaining more and more attention. The core of this technology is that it can effectively block the blood supply to the tumor, so that the tumor cells cannot get the nutrients and oxygen they need, thus achieving the effect of inhibiting or shrinking the tumor.
In embolization, the embolic materials used can be various particles, foams, microspheres, etc. These materials will be injected into the target blood vessels, quickly causing blood flow interruption.
Embolysis is not just a physical blockage of blood flow. In many cases, doctors will directly combine anti-cancer drugs with embolic materials to perform so-called chemoembolization, which further improves the effectiveness of treatment. Such a combination offers a more aggressive form of treatment, with promising results for certain types of cancer, such as liver cancer. Especially in patients with liver cancer, the tumor will usually be significantly reduced after embolization treatment, and the patient's survival period will be relatively prolonged.
History and development of embolization
The history of embolization can be traced back to 1968, when it was developed by Sadek Hilal. This technology was originally developed to treat patients with hemangiomas (vascular abnormalities). With the development of medicine and the advancement of technology, embolization is now widely used in many medical fields, not only in tumor treatment, but also in hemostasis, Treatments that reduce tumor size and even affect fertility.
Indications for embolization
Embodimentation is widely used. In addition to controlling active arterial bleeding, it is also suitable for the following situations, including but not limited to:
- Circulatory system abnormalities such as aneurysms and vascular malformations
- Certain types of cancer such as kidney disease and liver disease, especially hepatocellular carcinoma (HCC)
- Uterine fibroids
- Postoperative bleeding control
Techniques and procedures of embolization
This technique is usually performed by an interventional radiologist in a dedicated operating room. During the procedure, the doctor will deliver the embolic material into a specific blood vessel through a catheter and use digital subtraction angiography (DSA) technology to confirm the position of the catheter as needed. With the continuous advancement of technology, doctors can perform operations more accurately, thereby improving the safety and success rate of surgery.
Advantages and risks of embolizationThe most common embolic materials include microspheres, foams, and metal coils, and the choice of these materials will depend on the patient's specific condition and the desired treatment effect.
The advantages of embolization are its minimally invasive nature, which usually does not require large incisions during the operation, and the postoperative recovery time is relatively short. Compared with traditional surgical methods, the pain and infection risk suffered by patients are significantly reduced. However, this technique is not suitable for all patients and there may be certain risks during the operation, including the possibility of causing damage to healthy tissue or recurrence.
Future Outlook
With the continuous advancement of technology, the application prospects and efficacy of embolization will receive more and more attention from the medical community. Especially for cancer treatment, embolization is expected to achieve better therapeutic effects by combining with other treatment methods (such as radiotherapy and chemotherapy). This not only provides new treatment ideas, but also brings hope to many cancer patients.
So, as medical technology advances, will we see more breakthroughs in embolization in the future, making it a key weapon in the war against cancer?
