  Radioactive embolizing compositions - Patent 6562317
The use of vascular embolization, by itself, in the treatment of solid mass tumors is complicated by the fact that, upon embolization of the blood vessel feeding the tumor, alternative vascular routes can be generated by the tumor which continue to feed the tumor.
Embolization may entail deliberate sacrifice of the organ harboring the tumor, as in embolization of renal cancers.
The particular amount of embolizing composition employed is dictated by the total volume of the vasculature to be embolized, the concentration of polymer/prepolymer in the composition, the rate of precipitation (solids formation) of the polymer, etc., and the total level of radiation to be delivered.

 Compositions for use in embolizing blood vessels - Patent 6342202
In addition to use in embolizing blood vessels, these compositions can also be employed in the reversible sterilization of mammalian males and females..sup.5,6 In the former case, the polymer composition is injected into the vas deferens and up on contact with the aqueous fluid therein, precipitates to block the vas.
The particular amount of embolizing composition employed is dictated by the total volume of the vasculature to be embolized, the concentration of polymer in the composition, the rate of precipitation (solids formation) of the polymer, and the like.
In this regard, it is preferred to use polyethylene in the catheter components because of its inertness in the presence of the embolizing composition described herein.

 Uterine Fibroid Embolization (UFE)
Uterine fibroid embolization is not performed by gynecologists, who, for various reasons, may sometimes not discuss it as a possible option for their patients with fibroid tumors.
Although uterine fibroid embolization is a relatively new treatment for fibroids, the same procedure has been used with great success to treat emergency uterine bleeding for more than 25 years.
Uterine fibroid embolization blocks, or "embolizes" the blood vessels that "feed" the uterine fibroid, causing it to shrink.

 Patent 6,759,028
The solidified mass embolizes the vascular site thereby ablating or obliterating at least part of the AVM and the radioactivity attendant with the composition results in further ablation or obliteration of the AVM and inhibits regrowth of the AVM.
In turn, such embolization ablates at least part of the AVM and delivers a controlled amount of radiation to further ablate the AVM and to inhibit regrowth.
When a prepolymeric composition is introduced in vivo, the prepolymer rapidly polymerizes in situ (preferably in less than 15 minutes and more preferably in less than 5 minutes) and a solid non-migratory mass forms which mass is the water insoluble polymer and radioisotope encapsulated therein as well as any non-radioactive water insoluble contrast agent.

 EMBOLIZATION THERAPY FOR VEIN OF GALEN MALFORMATION - Pediatric Oncall
Treatment consists of clipping the malformation and restoring normal blood flow, but the operation requires retracting the newborn's brain posing a high risk of death from bleeding.
A new, less-invasive catheter approach is innovated that embolizes these malformations bringing the chance of survival for these babies up to 50 percent.
The procedure has to be done in stages to decrease the risk of embolization in the large carotids and consists of introduction of a catheter through the femoral artery upto the carotids and injecting the drug.

Most commonly, the brain is injured when a plaque (that is in an artery that leads to the brain) breaks off (embolizes) and wedges itself deep into the brain substance.
In this case the ischemic attack affects the retina, or the transducer of light in the eye to images perceived by the brain.
Amaurosis fugax occurs because debris primarily from the carotid (neck) arteries embolize to the retinal artery and renders some cells of the retina nonfunctional.

 Medical Newswire - Healthcare, Biotechnology News Release Service
Question: Our radiologist wants to code twice when he embolizes the right bronchial artery for a right lung tumor and the left bronchial artery for a left lung tumor.
The right and left bronchial arteries supply the right and left lungs, which are two separate surgical or operative fields, as opposed to the right and left uterine arteries, which supply the same end organ (and would therefore be considered a single operative field).
Because your radiologist embolized the separate bronchial arteries to treat separate conditions (two separate tumors), you can bill twice for this procedure.

When a blood clot dislodges from the atria and embolizes to the brain, a sudden onset of paralysis (embolic stroke) can occur.
A blood clot, which embolizes to the lungs, can cause injury to the lung tissues (pulmonary infarction), with resulting symptoms of chest pain and shortness of breath.
The goals of atrial fibrillation treatment include: 1) slowing the rapid heart rate (the rate of ventricular contractions); 2) preventing blood clot embolization and strokes; and 3) converting the irregular rhythm back to normal rhythm whenever possible.

The situation is only considered an emergency if the break occurs before thirty-seven weeks and results in significant leakage of amniotic fluid and/or infection of the amniotic sac.
A rare but frequently fatal complication of labor, this condition occurs when amniotic fluid embolizes from the amniotic sac and through the veins of the uterus and into the circulatory system of the mother.
The fetal cells present in the fluid then block or clog the pulmonary artery, resulting in heart attack.

 Atrial Myxoma -- eCureMe.com
It usually begins in the septum between the two heart ventricles, with 80% of the tumors growing into the left atrium.
Though it is a benign tumor, it can become serious when a part of it breaks off and embolizes (moves) into the blood vessels and causes an obstruction of blood flow.
If, for example, the tumor embolizes to the brain, it can block off part of the blood supply to the brain and cause a stroke.

If the clot breaks off and travels (embolizes), it may travel to the lungs causing a potentially fatal condition called pulmonary embolism (PE).
Risk factors for DVT formation include prolonged immobility, leg trauma, cancer, surgery (especially orthopedic) to the legs, certain medications (such as estrogen or birth control pills), or a genetic tendency to form blood clots.
Pulmonary embolization tends to cause severe shortness of breath, chest pain, and low oxygen levels, but since these are non-specific symptoms, other problems need to be ruled-out as well.

The continued embolism, the changing histology, and the 10-fold difference in fibrin uptake (high embolic versus low embolic cases) observed over the 64 h span of thrombus ages indicate evolving thrombus metabolism.
As the thrombus forms, its bonds are being lysed and thrombus fragments are embolizing, but at the same time the thrombus is 'repairing' with continuing fibrin uptake.
The biological age of this process is not predicted by its chronological age.

 Pulmonary embolism - The Doctors Lounge(TM)
A pulmonary embolism occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs, causing vascular obstruction and impaired gas exchange.
The most common sources of embolism are pelvic vein thromboses or proximal leg deep venous thromboses (DVTs).

Therefore, the tumor is richly vascularized - giving it a path to the systemic circulation; and, once the tumor "embolizes" the small tumor fragments are able to erode through the vessel and implant into the surrounding tissue.
There is a "cascade" theory for tumor embolization and metastasis.
Blood from the gut is "filtered" in the liver, and gastrointestinal metastases usually begin in the liver before they spread to other organs.

Thrombotic disorders: Diseases characterized by formation of a thrombus that obstructs vascular blood flow locally or detaches and embolizes to occlude blood flow downstream (thromboembolism).
Thrombi are mechanical masses that form within the cardiovascular system on denuded endovascular or prosthetic flow surfaces.
Subsequent antithrombotic therapy varies depending on whether the venous or arterial circulatory system is involved; the size and location of the involved vessels; the risks of extension, embolization, or recurrence; and the relative antithrombotic benefits and hemorrhagic risks.

 Novel strategy in antithrombotic therapy: inhibition of the initial phase of thrombogenesis
However, persons with inherited alterations in proteins that promote or prevent coagulation may be predisposed to excessive bleeding (hemophilia) or clotting (thrombophilia).
Persons with thrombophilia are at increased risk of developing a clot (a thrombus) that obstructs blood flow locally or that detaches and embolizes.
Current anti-thrombotic therapies focus primarily on the latter stages of the clotting cascade and there is a substantial demand for the development of novel therapeutics that target earlier events on this pathway.
