A bioresorbable stent is a tube-like device that is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. It is made from a material that can release a drug to prevent scar tissue growth. It can also restore normal vessel function and avoid long-term complications of metal stents. [1] [2]
Reperfusion therapy is a medical treatment to restore blood flow, either through or around, blocked arteries, typically after a heart attack (myocardial infarction (MI)). Reperfusion therapy includes drugs and surgery. The drugs are thrombolytics and fibrinolytics used in a process called thrombolysis.
Atherosclerosis is a broad term referring to loss of elasticity of arteries and more specific terms exist — arteriosclerosis and arteriolosclerosis — to narrow which arteries are diseased and can easily be confused due to similar spelling. Overall, atherosclerosis tends to affect the arteries of highest pressure: aorta, coronary, renal ...
Current concepts recognize that after three months the artery has adapted and healed and no longer needs the stent. [48] Complete revascularization of all stenosed coronary arteries after a STEMI is more efficacious in terms of major adverse cardiac events and all-cause mortality, while being safer than culprit-vessel-only approach. [49]
These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart muscle. These relatively narrow vessels are commonly affected by atherosclerosis and can become blocked, causing angina or myocardial infarction (a.k.a., a heart attack). The coronary arteries that run deep ...
a history of long-term intravenous therapy [1] (for air embolism) Bone fracture (for fat embolism) [4] A septal defect of the heart makes it possible for paradoxical embolization, which happens when a clot in a vein enters the right side of the heart and passes through a hole into the left side. The clot can then move to an artery and cause ...
In July 1980, Houston Astros starting pitcher J.R. Richard collapsed while playing a game of catch, and was found to have experienced a stroke due to severe blockage of his right carotid artery. Given the fact that shortly beforehand, he had been found to have near-total obstruction of the arteries supplying his right arm, he was eventually ...
The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel. [34] In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical ...
