Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
Since kidney function may already be impaired (up to half the kidney may be lost before function loss is detectable), preserving as much kidney as possible is vital when removing any lesion. Large angiomyolipomas are treated by embolization, which reduces the risk of hemorrhage and can also shrink the lesion.
When the kidneys are involved, the disease is referred to as atheroembolic renal disease. [3] The diagnosis usually involves biopsy (removing a tissue sample) from an affected organ. Cholesterol embolism is treated by removing the cause and giving supportive therapy; statin drugs have been found to improve the prognosis.
Thrombotic embolism, branch left pulmonary artery, hemorrhagic infarction apex left lower lobe. An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel. [1]
An embolism may be made from any one of numerous materials that may find itself in a blood vessel, including a piece of a thrombus, known as a thromboembolism, air from an intravenous catheter, fat globules from bone marrow, amniotic fluid during birth. [1]
Renal vein thrombosis is the obstruction of the renal vein by a thrombus. This tends to lead to reduced drainage from the kidney. [8] ... Embolization A thrombus may ...
Arterial embolism is a sudden interruption of blood flow to an organ or body part due to an embolus adhering to the wall of an artery blocking the flow of blood, [1] the major type of embolus being a blood clot (thromboembolism).
Kidney: kidney tumors such as renal cell carcinoma can be treated with image guided ablation (RFA, MWA, cryotherapy) with similar results to partial nephrectomy. [25] Benign kidney tumors such as angiomyolipomas can be treated with transarterial embolization to shrink the tumor size and reduce the risk of rupture/bleeding.
