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.

The Skull Anatomy

Learning Objectives For The Skull •  List and identify the bones of the brain case and face • Locate the major suture lines of the skull and name the bones associated with each. • Define sinuses and identify the location of each • Identify the bones and structures that form the nasal septum and nasal conchae, and locate of the hyoid bone •  Identifythe bony openings of the skull Anterior View of the Skull  Lateral View of Skull Bones of the Brain Case Parietal Bone Temporal Bone Frontal Bone Occipital Bone Sphenoid Bone Ethmoid Bone Sutures of the Skull Facial Bones of the Skull Maxillary Bone Palatine Bone Zygomatic Bone Nasal Bone Lacrimal Bone Inferior Nasal Conchae Vomer Bone Mandible Paranasal Sinuses Hyoid Bone The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclo...

Introduction to ECG

MEANING OF ECG An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes. There are two ways to learn ECG interpretation — pattern recognition (the most common) and understanding the exact electrical vectors recorded by an ECG as they relate to cardiac electrophysiology — and most people learn a combination of both. This tutorial pairs the approaches, as basing ECG interpretation on pattern recognition alone is often not sufficient. Parts of an ECG The standard ECG has 12 leads. Six of the leads are considered “limb leads” because they are placed on the arms and/or legs of the individual. The other six leads are considered “precordial leads” because they are placed on the torso (precordium). The six limb leads are called lead I, II, III, aVL, aVR and aVF. The letter “a” stands for “augmented,” as these leads are calculated as a combination of leads I, II and ...

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.
