Angiograms

Angiograms are a type of x-ray procedure used to assess blood vessels and blood flow throughout the body. Using x-ray technology and contrast solutions, angiograms are performed to gain clear images of the veins and arteries in areas like the arms, legs, heart, lungs or brain. These tests help doctors to determine if there are blood vessel blockages, weakening of the vessels, internal bleeding and damage to the circulatory system caused by illness, or injury. In some cases, doctors are able to treat the problem during the angiogram procedure.

In preparation for the angiogram, patients are given a local freezing at the needle site (similar to dental freezing). An intravenous line is started and monitoring equipment is connected to the patient to evaluate breathing, pulse, and heart functioning. Patients are placed on an x-ray table and positioned under a fluoroscope. A catheter is inserted into an artery or vein of the arm or groin area using a needle. The fluoroscope is used to locate the position of the catheter. The catheter tip is moved up the artery or vein until it reaches the area being examined.

A contrast (dye) is injected into the patient via the catheter to visualize the blood vessels. Patients may experience mild discomfort and a warm sensation with the movement of the catheter and injection of contrast solution. Once everything is in place, a series of x-rays are taken and immediately reviewed. The procedure may require many injections of contrast and more x-rays.

Angiograms should not be performed on pregnant patients. Patients are to advise their doctors of any adverse reactions they may have had to medications, contrast solutions or iodine, or of any allergies they may have. They should also inform their doctor if they have asthma or breathing problems. Prior to the test, fluid and food restrictions will be explained. As with other types of x-rays, patients are asked to remove all jewelry and metal objects. They may be required to wear a gown. Angiogram testing can vary from one to three hours and a period of rest will be required after the procedure in order to monitor blood clotting and to allow for sedatives to wear off. Additional bed rest is usually required when patients return home.

PICC Line Insertion

A PICC line catheter is an intravenous line placed in the vein, usually in the elbow area. This intravenous line may be left in the vein for an extended period of time. A nurse is able to access this line via a small port left outside the vein.

This intravenous line may be used to deliver medications or fluids or for taking blood for tests ordered by the client's doctor.

The PICC line is inserted into a vein using "sterile" technique. The doctor and the x-ray staff may wear a mask, gown and gloves for this procedure. After the catheter is positioned small sutures will help secure the catheter in place. A small bandage will be used to cover the insertion site.
