The microspheres are small enough to flow through the hepatic arteries, but they are too large to pass through the small blood vessels within the tumor, where they become permanently lodged in the tumor bed. The majority of microspheres are approximately 32 microns in diameter, about a third of the width of a human hair. SIR-Spheres Y-90 resin microspheres are targeted directly at the liver tumors via the hepatic artery, so exposure to the remaining healthy liver tissue is minimized. The normal liver tissue takes about 90% of its blood supply from the portal vein that flows from the intestine while liver tumors receive about 90% of their blood supply from the hepatic artery.

The SIRT procedure enables radiation – which is often used to treat cancer – to be sent directly into the liver tumors by using the tumor’s blood supply. How do SIR-Spheres ® Y-90 resin microspheres work? These liver tumors are also known as secondary liver metastases because the cancer cells have spread to the liver from the primary colon, rectal, lung, breast or bone tumor.

SIR-Spheres Y-90 resin microspheres are approved in the United States for the treatment of inoperable liver metastases in combination with hepatic arterial chemotherapy using FUDR (floxuridine). Thousands of patients have now been treated both in research studies and routine clinical practice at centers of excellence around the world. The development of SIR-Spheres Y-90 resin microspheres started in Australia in the 1980s,with regulatory approval being granted in the United States in 2002. SIRT is a targeted treatment for liver tumors that delivers millions of tiny radioactive beads called SIR-Spheres Y-90 resin microspheres directly to the liver tumors.

I hope this situation can be rectified immediately. I refuse to pay or provide insurance info for bills that aren't mine, because ironically, that itself would be fraud. If my credit is affected, I will be suing all entities and seeking damages. I refuse to pay a ***** because I didn't receive any care and these bills are not mine! If need be, provide me all the records, receipts, and such so that I can contact the police and *** for identity fraud to have this thrown out. You'd easily see it wasn't me and any signature and such wouldn't match. The hospital should look at security footage to see who used my name and info, and what info they provided. It all seems very shady when I deal with them. All I get are agents on the phone who refuse to help and refuse to mail proof of this supposed care received. I didn't feel comfortable giving my SS number and just gave my address and name. Then, they said they didn't have my supposed personal information and asked for my SS number and other info. The first several times, they claimed their computers were down and they couldn't look anything up, but they could take payment.

********** was unhelpful when I called them and RP/Singleton even more so the MULTIPLE TIMES I've called them. Not only that, I did not receive medical care ANYWHERE IN THE ***** on those dates! I'm thinking it's possible someone may have stolen my identity and tried to receive care under my name/Social Security number/etc.
