Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to an aneurysm or blood vessel through the implantation of detachable platinum wires, with the clinician inserting one or more into the blood vessel or aneurysm until it is determined that blood flow is no longer occurring within the space.
Flow diverters are treatment for intracranial aneurysms alternative to endosaccular coil embolization, although the techniques can be combined, especially in large/giant aneurysms. It is mainly effective in wide neck unerupted saccular aneurysms , that are difficult to coil because of the tendency of the coils to fill the parent artery ...
The coil induces clotting within the aneurysm, which reduces the risk of rupture. Multiple coils may be used depending on the size. [ 33 ] Imaging studies ( DSA , CTA , or MRA ) help characterize the aneurysm to decide the best course of treatment, whether endovascular coiling or surgical clipping.
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 ...
Hemosuccus pancreaticus is a rare cause of hemorrhage in the gastrointestinal tract.It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine.
Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
Endovascular coiling refers to the insertion of platinum coils into the aneurysm. A catheter is inserted into a blood vessel, typically the femoral artery, and passed through blood vessels into the cerebral circulation and the aneurysm. Coils are pushed into the aneurysm, or released into the blood stream ahead of the aneurysm.
[3] [4] Another type of treatment possible by angiography (if the images reveal an aneurysm) is the introduction of metal coils through the catheter already in place and maneuvered to the site of aneurysm; over time these coils encourage formation of connective tissue at the site, strengthening the vessel walls.
