After a blocked artery is treated with angioplasty to restore blood flow, the artery may become blocked again. This is called restenosis. One way to prevent restenosis is to place a stent inside the artery at the spot where the blockage was cleared by angioplasty. A stent is a tiny, metal mesh tube that is placed with a catheter and permanently embedded within the artery wall to prop open and prevent it from collapsing.
Associations between Agent Orange and other dioxin-contaminated herbicides and structural birth defects like spina bifida, oral clefts, heart defects and hypospadias may be just the âtip of the icebergâ.
In 2009, the US Department of Veterans Affairs added Parkinsonâs to a list of diseases possibly associated with exposure to Agent Orange.â Separate research has further revealed that ambient exposure to organophosphate pesticides also increased the risk of developing Parkinsonâs disease.
