Admin_NHT Staff asked 4 years ago Angiography is carried out in the radiology department. Catheter angiography conducted by using Catheter. Use of catheter in the angiography help to combined diagnosis and treatment together. The clear and accurate images obtained by catheter angiography reduced the need for surgery. The catheter is a thin plastic tube inserted into the body by making the small insertion in the body. The ECG electrodes may be placed in the following position.
| V1(C1) | Fourth intercostal space at the right sternal border |
| V2(C2) | Fourth intercostal space at the left sternal border |
| V3(C3)
| Halfway between leads V2 and V4
|
| V4(C4) | Fifth intercostal space in the midclavicular line |
| V5(C5) | Left anterior axillary line on the same horizontal plane as V4 |
| V6(C6) | Left midaxillary line on the same horizontal plane as v4 and v5 |
| RA(R) | Right arm (Inner wrist) |
| LA(L) | Left arm (inner wrist) |
| RL(N) | Right leg (inner ankle) |
| LL (F) | Left leg (inner ankle) |
V4 lead is placed below the breast tissue in a woman because breast tissue may impact the ECG amplitude. The chest must be cover up with a blanket to avoid exposure. ECG electrodes should be removed when there is no requirement of ECG.
- Uses: – Catheter angiography is useful to study the blood vessels in the body organs like the brain, neck, heart, chest, abdomen, pelvis, legs and feet, arms, and hands. Also, the physician help to identify abdominal aortic aneurysm, abnormalities present in the chest. Detection of plaque in the carotid artery, it is also helpful in the kidney transplant procedure or stent placement procedure. It is helpful to identify the injuries that happen in the arteries. To study the dissection of the aorta.
- Procedure: – Patients must have to inform the physician about their medication which is taken. A patient asks to wear loose clothing and remove all jewelry and metallic accessories. Pregnant woman must tell about her pregnancy to the physician. Also breastfeeding women must have to ask a physician about the procedure to avoid absorption of contrast material into breast milk. A patient must have to take a fast for 10 hours before the exam. A technologist will insert IV line into a small vein in the arm. Small blood drops are removed before starting the procedure. The area of catheter insertion is must be clean and sterilized with local anesthetic. Technologists make small insertions and insert the catheter into the artery. When catheter is reached to the final destination then numbers of x-rays are taken. Then the catheter is removed and the incision area is closed by aping pressure for 15 minutes.
