Chief of the ward: Mr. Khorsand
Explanations: This ward having the most advanced systems in the world and also enjoying experienced specialized physicians offers the best kind of diagnosis in angiography and the most urgent therapy in angioplasty to patients.
It is better to know some information about angiography at the beginning:
We may hear and see something about heart everywhere. From the very ancient times people thought that their movements are because of their hearts. Maybe this idea is originated from this fact that whenever someone is afraid or excited heart beat rises consequently. However, nowadays we know that all our emotions are from our brain and this is the brain that commands our heart how to act.
Heart is a muscle. As we may know there are a lot of muscles in our body among them our hand, leg, back, loins and so on. But heart acts as a special muscle in our body that is located in the middle of chest and leaning a little to the left. It is measured as our handful fist. Heart receives blood which is full of oxygen and food from our lung and pumps it to all parts of our body. Heart not only send oxygen and food to all organs but also sends out of the body the superfluous materials by the help of kidneys.
Heart will become full of blood prior to each beat. Then heart will be contracted and pumps blood to all other parts of body. It will be fed by coronary blood-vessels.
One of the diagnosis methods for heart congenital and valvular disease is angiography and in some cases they are remediable.
What is angiography?
Angiography is a kind of imaging system from blood-vessels or different cardiac chambers which is done by x-ray or alpha-ray.
Angiography can include heart, brain, kidneys and also other peripheral vessels of the body which are suspected to have narrowness, obstruction, or dilatation.
How angiography works? A narrow and delicate plastic tube which is called Catheter is used. The catheter will be send inside or near the considered site. Then a contrast agent is injected and by the help of x-ray at the same time imaging will be done.
Of course, diagnosis can be done by other methods nowadays such as: CT scanner and MRI in which there is no need to use catheter.
Nevertheless, there are wide uses of catheters in patients who need angiography, angioplasty or stent implantation and also in patients who need surgery.
It can be said that the following cases will be specified and distinguished by angiography:
-To determine unusual dilatation of the vessels
-Diagnosing abnormal dilatation of the blood vessels and also diagnosing & estimating the site of internal bleeding.
-Diagnosing disturbances of brain vessels
-Show renal vascular diseases and evaluation of these vessels for kidney transplantation.
-Determination of the shape of the great vessels such as aorta from aneurysm or abnormal cases points of view.
-To fix the bleeding source
-Diagnosis of atherosclerosis
Preparing patient for angiography:
In order to prepare for angiography patient is being asked to eat anything 4 to 8 hours prior to the test unless necessary medicines with a little water.
Usually it is tried to train patients before angiography in different ways such as written instructions, face to face instructions, pictures and video films.
One of the most important points in this test is that if patient has allergy to any materials or is pregnant, it must be reported to the physician and/or related medical team.
The method of performing angiography:
Usually anti-allergy or; according to the discretion test; tranquilizers medicines are used before arriving to angiography ward in different medical centers.
After patient arrives to angiography ward and after connecting the EKG cables by small adhesive tapes and or special bracelets, groin or in particular cases elbow area will be disinfected (soak in antiseptic) and the same as other surgeries all parts of body will be covered by sterilized clothes. After injecting a local anesthesia on the sterilized area angiography will begin.
In this condition, in spite of the fact that patient has no pain and is in full consciousness state, by the help of very delicate tube catheter and simultaneously with injecting contrast media and taking imaging the intended test will be continued. After taking images from different aspects angiography is over. When the catheter entrance site is dressed patient will be transferred to the related ward.
In this step, patient is asked to stay in supine position and with extended legs for 2 up to 6 hours.
Physicians who cooperate with angiography ward of Shiraz Central Hospital are outstanding subspecialist cardiologists and professors of Shiraz University of Medical Sciences and all are members of university scientific board (teaching staff) as follows:
