Bony metastases preoperative embolization



For hyper vascular tumours like renal cell carcinoma and thyroid carcinoma, preoperative embolization of metastases was first described. The main goal of this systematic review was to find long bone metastases that could benefit from preoperative embolization to reduce perioperative blood loss and blood transfusions. Because any less than total devascularization increases blood loss and red blood cell transfusion during surgery, interventional radiologists should pursue and embolize every feeder to the metastasis.

When cancer cells move from their initial place to a bone, this is called bone metastasis.

 Almost all cancers can move to the bones (metastasize). However, some cancers, such as breast cancer and prostate cancer, are more prone to spread to the bones. In the treatment of bone metastases, transcatheter embolization is effective and reliable. 

 When surgery is planned, a catheter can be inserted into an artery (typically in the leg, as for a cardiac angiography) and a tiny catheter threaded up through it to the tumor's artery or arteries. A substance is injected to cut off the tumor's blood supply (this is called embolization).  

Preoperative embolization treatments are constantly improving, allowing surgeons to conduct or improve the results of forthcoming surgical interventions.

Dr.Sandeep Sharma(IRFacilities) is the best doctor for Acute Stroke Mechanical Thrombectomy. He is an expert in suction retrieval and stent retrieval and uses both techniques in perfect combination.

Bilateral Varicocele Embolization

Varicoceles are not life-threatening, however, they can be linked to serious illnesses in rare cases. If a varicocele arises on the right side of the abdomen rather than the left, for example, make sure there is no mass or other abnormalities in the abdomen that could be causing it. Blood is transported back to the heart via veins throughout the body. They usually feature valves to keep the blood flowing in the right way. When the valves in the testicular vein don't work properly, blood can pool in the scrotum, resulting in a varicocele. They commonly happen on the left side, and they're caused by the testicular vein's path through the abdomen. Varicocele is a frequent condition that is not hazardous. In fact, a varicocele affects 15% of all adult men. Many men's varicocele will go undiscovered for the rest of their lives or may create no complications at all. Varicoceles affect about 20% of teens, therefore a portion of them will most likely resolve on their own. The

LIVER ABSCESS DRAINAGE

Image
A pus-filled patch of fluid within the liver is known as a pyrogenic hepatic abscess. Pyogenic denotes the production of pus. A liver abscess can arise from a number of various causes, including a blood infection, an abdominal infection, or an infected abdominal injury. An abscess in the liver is a serious infection. It has the potential to cause major issues and even death. It can cause tissue damage in the spot where it is discovered. Fever, discomfort, nausea, diarrhoea, and loss of appetite are all possible symptoms. The whole first treatment for an amebic liver abscess is amebicidal medicines. The medication of choice is metronidazeole. The size of the abscess is a key determinant in deciding how well medical therapy works. Other treatment options include percutaneous needle aspiration and/or catheter drainage.  The type of abscess that occurs is influenced by one's age. People in their 40s and 60s are more likely to have a liver abscess that is not caused by trauma.  The foll

What is Interventional Radiology?

Image
  The medical technology has done so much progress in the past one decade that it’s sometimes surprising. Interventional radiology is one such amazing medical innovation that involves medical imaging which guides minimally invasive surgical procedures that help in diagnosis, treatment and cure of many different kinds of treatments. For imaging, the modalities used are ultrasound, MRI, CT and fluoroscopy. Why Interventional Radiology? Many surgeries are now being switched to the method of Interventional radiology and that is because the IR procedure is known to be more effective compared to their traditional surgical counterparts. This method is any day less risky, less painful and even costs you way lesser comparatively. These reasons are influencing people to prefer the IR treatment methods and hence it is starting to expand all across the world. How does Interventional Radiology work? There are various broad range procedures performed under Interventional Radiology like treating tumo
