冠狀動脈血管成形術也稱為經皮冠狀動脈介入治療
該手術是在稱為冠狀動脈的血管上進行的,
它們為你的心肌提供氧氣
目標是在一種稱為斑塊的物質顯著縮小這些血管的情況下恢復血流
開始手術時,醫生會麻醉您腹股溝的皮膚
針將穿過您的皮膚并進入股動脈
接下來,柔性導絲將穿過針進入您的動脈
然后,針將被抽出
它將被替換為稱為護套的小型柔性管
這允許進入您的動脈
當醫生插入鞘管時,您可能會感到壓力,但您不會感覺到它在動脈內移動
接下來,導絲將被推進到您的心臟
一根稱為導管的柔性管將通過導線進入您的冠狀動脈
手術的進展將通過稱為熒光鏡的 X 射線設備進行檢查
此時,您的醫生將移除導絲
然后,醫生將導管尖端移入冠狀動脈內進行檢查
一種特殊的染料將被注射到動脈中
這可以讓您的醫生通過熒光鏡更好地觀察它
染料會使動脈中的任何堵塞都顯露出來
如果發現嚴重堵塞,醫生會將導絲插入動脈
導管尖端的氣球將沿著導絲移動至堵塞處
當氣球膨脹時,它會擴張動脈并改善血流
發生這種情況時您可能會感到胸部不適
此后,您的醫生將放氣并取出氣球
可以將稱為支架的金屬絲網管放置在治療區域中
支架有助于保持冠狀動脈開放
您的醫生會選擇合適尺寸的支架,將其壓縮在氣球上
支架將通過同一條導絲移入動脈
當氣球充氣時,支架將膨脹并鎖定到位
取出球囊導管后,支架將留在原位以保持動脈開放
手術結束時,導絲將被移除

A coronary angioplasty procedure is also known as percutaneous coronary intervention
冠狀動脈血管成形術也稱為經皮冠狀動脈介入治療
The procedure is done on blood vessels called coronary arteries
該手術是在稱為冠狀動脈的血管上進行的,
they supply your heart muscle with oxygen
它們為你的心肌提供氧氣
The goal is to restore blood flow if a substance called plaque has significantly narrowed these vessels
目標是在一種稱為斑塊的物質顯著縮小這些血管的情況下恢復血流
To begin the procedure the doctor will numb the skin in your groin
開始手術時,醫生會麻醉您腹股溝的皮膚
A needle will be placed through your skin and into the femoral artery
針將穿過您的皮膚并進入股動脈
Next a flexible guidewire will be passed through the needle into your artery
接下來,柔性導絲將穿過針進入您的動脈
Then the needle will be withdrawn
然后,針將被抽出
It will be exchanged for a small flexible tube called a sheath
它將被替換為稱為護套的小型柔性管
This permits access into your artery
這允許進入您的動脈
You may feel pressure when the doctor inserts the sheath but you will not feel it moving inside your artery
當醫生插入鞘管時,您可能會感到壓力,但您不會感覺到它在動脈內移動
Next the guidewire will be advanced up to your heart
接下來,導絲將被推進到您的心臟
A flexible tube called a catheter will be advanced over the wire to your coronary arteries
一根稱為導管的柔性管將通過導線進入您的冠狀動脈
The progress of the procedure will be checked with an x ray device called a fluoroscope
手術的進展將通過稱為熒光鏡的 X 射線設備進行檢查
At this point your doctor will remove the guidewire
此時,您的醫生將移除導絲
Then the doctor will move the tip of the catheter just inside the coronary artery to be examined
然后,醫生將導管尖端移入冠狀動脈內進行檢查
A special dye will be injected into the artery
一種特殊的染料將被注射到動脈中
This allows your doctor to view it better with the fluoroscope
這可以讓您的醫生通過熒光鏡更好地觀察它
The dye will make any blockages in the artery stand out
染料會使動脈中的任何堵塞都顯露出來
If a significant blockage is found your doctor will insert a guidewire into the artery
如果發現嚴重堵塞,醫生會將導絲插入動脈
A balloon on the tip of the catheter will be moved along the wire to the blockage
導管尖端的氣球將沿著導絲移動至堵塞處
When the balloon inflates it will expand the artery and improve the blood flow
當氣球膨脹時,它會擴張動脈并改善血流
You may feel some chest discomfort while this is happening
發生這種情況時您可能會感到胸部不適
After this your doctor will deflate and remove the balloon
此后,您的醫生將放氣并取出氣球
A wire mesh tube called a stent may be placed in the treated area
可以將稱為支架的金屬絲網管放置在治療區域中
The stent helps keep the coronary artery open
支架有助于保持冠狀動脈開放
Your doctor will choose the proper size stent which is compressed over a balloon
您的醫生會選擇合適尺寸的支架,將其壓縮在氣球上
The stent will be moved into the artery over the same guidewire
支架將通過同一條導絲移入動脈
When the balloon is inflated the stent will expand and lock into place
當氣球充氣時,支架將膨脹并鎖定到位
After the balloon catheter is taken out the stent will stay in place to hold the artery open
取出球囊導管后,支架將留在原位以保持動脈開放
At the end of the procedure the guidewire will be removed
手術結束時,導絲將被移除
