Radialinės arterijos pašalinimas (kam, kaip jis veikia?)

A removal of the radialinė arterija can be performed as part of a bypass operation. Bypass surgery is used to bridge a narrowing of the vainikinės arterijos. Jei koronaras laivai no longer allow enough kraujas to pass through, the širdis muscles may be undersupplied.

To prevent this, an arterija arba venas is used as a bypass. For example, the arterija is placed before and after the narrowing so that the kraujas can continue to flow through this bypass. The removal of the radialinė arterija is minimally invasive, i.e. with only a few incisions.

The surgeon can then endoscopically bind and cut the arteries at two points. The two ends are closed to prevent bleeding. Various collaterals or anastomoses ensure that the supply areas of the radialinė arterija continue to be supplied with kraujas (the ulnar artery takes over the tasks of the radial artery).

Due to anatomical variations in the supply, the blood flow through the ulnar arterija should be tested. The removal leaves a 2 to 3 cm long scar on the dilbis. A further reason for the removal of the radial artery can be, for example, during plastic/reconstructive surgery.

In order to restore missing skin, a piece of skin including blood supply from another part of the body must be donated. In this context, the skin of the dilbis with the radial artery may be considered. This article may also be of interest to you: Heart bypass – when will it be used?

Radial artery and heart catheter

A cardiac catheterization is an invasive (but not surgical) examination of the left or right širdis with access via a vessel. Laivai in the groin or arm can be used for this purpose. To examine the right širdis, a venous access is used, to examine the left heart an arterial access.

A left heart catheter examination can therefore be performed via the radial artery, for example. Here a catheter is inserted into the radial artery and pushed up to the heart under Rentgeno control. Once the catheter has reached the left heart, various examinations can be performed, such as measuring the pressure of the kairysis skilvelis or imaging the left ventricle using a contrast medium.

It is also possible to use this catheter to assess the vainikinės arterijos with regard to coronary heart disease or to initiate interventional steps. For example, it is possible to reopen narrowed laivai with a balloon dilatation and implant stents. At the end of the examination, the catheter is withdrawn and the wound closed. A pressure bandage is often applied to prevent secondary bleeding.
