Final answer:
Open transluminal balloon angioplasty involves using a catheter with a balloon to dilate an occluded renal artery, which is a correct statement. This procedure restores blood flow and prevents kidney damage.
Step-by-step explanation:
Open transluminal balloon angioplasty of the renal artery is a factual statement. Angioplasty is a medical procedure involving the mechanical dilation of a blocked artery. A catheter with an expandable balloon is inserted into a peripheral blood vessel, often the femoral artery in the leg, and navigated to the blockage site within the renal artery. Once properly positioned, the balloon is inflated, which compresses the plaque against the artery walls and expands the vessel diameter to increase blood flow. Afterwards, the balloon is deflated and withdrawn, and a stent might be placed to keep the artery open.
This procedure is especially important in cases where the renal artery is occluded because the kidneys are vital for filtering waste from the blood and maintaining overall body homeostasis. If a blood clot was present in the renal artery, it could lead to impaired kidney function or kidney damage due to reduced blood flow. Angioplasty provides a nonsurgical approach to restore blood flow and prevent further health complications.
