Depends on tissue: Embolization refers to placing a device in an artery supplying tissue downstream so as to induce blood clots closing off blood flow. Thus response is powerfully a function of what artery is embolized & whether collateral blood supply is present via other artery pathways so as to reduce the impact of blood supply loss on cell/tissue ischemia (insufficient blood supply for some/all cells to live). ...Read more

The brain in the form of a stroke or a bleed. That being said, the rate of complication from a coiling of an aneurysm is extremely low in experienced hands. ...Read moreSee 2 more doctor answers
When a varicocele vein is embolized, can the same vein below the embolization coil continue to try to pass blood back to the heart? Can this cause the vein to remain engorged and for how long?

Is it possible to have a varicocele embolization undone (i.e. remove the coil)? If so, are there any risks?

Directed ischemia: There are a variety of techniques used to embolize a lesion. A catheter is used to select as precisely as possible the blood supply to the target. Once in place any number of materials are injected via the catheter with the goal to block as completely as possible the blood supply to the target and cause the target to infarct by loss of blood supply. This can be done under local or general anesthes. ...Read moreSee 1 more doctor answer
Clots moving: Clots, or other plaque, devices, fragments may move in arteries or veins and end up in peripheral capillaries or lungs(pulmonary embolism).
