Angiography

 Angiography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers.


An arteriography is a procedure that produces an image of your arteries. During the procedure, your doctor will use contrast material, or dye, and X-rays to observe the flow of blood through your arteries and note any blockages. This procedure, also known as an angiogram, can be done on many different parts of your body.

Venography is a procedure to demonstrate the veins by using contrast media and others materials as for arteriography

INDICATIONS 

• Blockage of the blood Vessels.
• Suspected aneurysm.
• Renal artery stenosis.
• Renovascular hypertension.
• Trauma.
• Palpable renal masses.
•Chronic pyelonephritis.
• Renal abscesses.
and determination of the suitability of a (donor) kidney for renal transplantation.

CONTRAINDICATIONS 

  • Coagulopathy.
  • Decompensated congestive heart failure.
  • Hypertensive crisis.
  • Stroke or CVA.
  • Refractory arrhythmia.
  • GI hemorrhage.
  • Pregnancy.
  • Inability for patient cooperation.

EQUIPMENTS 

  • Angiography Systems.
  • Angiography Catheters.
  • Angiography Contrast Media.
  • Vascular Closure Devices (VCDs)
  • Angiography Balloons.
  • Angiography Guidewires.
  • Angiography Accessories.


PATIENT PREPARATION 

Don't eat or drink anything after midnight before your angiography,
Take all your medications to the hospital with you in their original bottles. ...
If you have diabetes, ask your doctor if you should take insulin or other oral 
The patient will change the cloth into hospital gown.

TECHNIQUE/ PROCEDURE 

An angiogram uses X-rays and a special dye (contrast) to take Image of the arteries in your brain, heart, and kidneys. The dye is injected into a small tube or catheter into a vessels in your groin or (sometimes) your arm. The small tube is inserted after an injection of local anaesthetic around the vessels.

HAND X-RAY

The basic projections are P.A and Lateral , ➢ Postero anterior (Dorsi-palmar P.A):- The patient is seated along side the table, the forearm is placed pronated on the table with the palmar surface of the hand in contact with the cassette. With the fingers slightly separated and extended to ensure that they remain in contact to the cassette. Centering point: - Center to the head of the third metacarpopalangeal joint. ➢ Dorsi-palmar oblique: - From the PA position the patient will now rotate his/her hand approximately 45° degrees, ➢ Another modified 15° degrees, Centering point: - Center to the 4th metacarpal bone. Essential image characteristics, The image should demonstrate the bones clearly and soft tissue outline no rotation or motion. References: MIT. Abdussalam A.

DARKROOM ILLUMINATION

 Darkroom Illumination: - dividend into 2 ordinary white light and safe light. White light is important because of the following  • To inspect and maintain cassette and screens • Cleaning of all work surfaces and floors  • And to services the processors  Sitting of the white light  * Sited close to the ceiling (to avoid casting strong shadow) * Moderate in intensity (60W tungsten or 30W fluorescent) (accommodation easier after safe light) * Centrally place or otherwise  All films get fogged when exposed by the white light  Safe Light  A safe light is a red light bulb situated in a darkroom at a distance of 1.2m (4 ft) off the working surface and use for a processing purpose. And a colored lighting which provides sufficient illumination by which one can handle, manipulate and process film with no significant fogging occurring,  These ensure loading and unloading of x-ray cassette much easier and provides pleasant working condition for the pers...

WRIST X-RAY

The basic projections are P.A and Lateral  ➢ Postero anterior (P.A):- The patient is seated along side the table with the affected side in contact with the cassette. Flexed the elbow joint and the arm is abducted, so that the anterior aspects of the forearm and the palm of the hand should be in contact with the cassette. The fingers are slightly separated to bring the anterior aspects of the wrist in contact to the cassette. Centering point: - Center mid way between the median and lateral styloid process.  ➢ Lateral: - from the postero anterior the wrist is rotated externally to bring palm of the hand vertically, the hand is rotated externally slightly further to ensure that the radial and styloid process are superimposed. Centering point: - Center to the lateral styloid process. Radiological consideration, The radiograph should demonstrate the all of the carpal bones clear and part of the metacarpal and forearm.
