Therapeutic Angiography in Israel

Coronary Therapeutic Angiography at the Top Ichilov Medical Center

In the coronary angiography department, along with diagnostic procedures such as diagnostic angiography of vessels, therapeutic procedures are also performed.

If the diagnostic process visualizes a pathological process, identifying the focus of damage in the coronary vessel, the goal of therapeutic angiography is to eliminate the defect. Using angiography, the narrowing of the vessel is expanded, a thrombus is removed, and stenting of the coronary arteries is performed.

The development of methods for treating narrowing of the heart vessels has progressed in different directions; some (expanding the vessel by drilling or bougienage, using lasers) have not found wide application, while angiography, on the contrary, has immediately and permanently entered medicine. Currently, the expansion of the vessel lumen using balloon catheterization and subsequent stenting of the affected vessel area is widely used.

Typically, the angiography procedure aimed at expanding the vessel walls lasts about 40 minutes, but this time may vary depending on the anatomical features of the patient and the vascular system, and of course, the experience and qualifications of the physician play a role.

Stenting of Coronary Arteries

Technique of the Balloon Catheterization Procedure. A balloon catheter is introduced through the nearest large artery into the vessel, conducted to the site of narrowing, where the balloon is inflated with air (manually, the physician must feel the tension inside the balloon), the walls of the balloon press the sclerotic plaque against the walls of the vessel, air is released from the balloon, and the catheter is removed. This procedure is often insufficient for sustained vessel expansion; half of the patients experience a recurrence. At the site of the previous narrowing, the vascular wall grows back, and the lumen narrows again, so the usually expanded vessel wall is fixed with a stent.

A stent is a structure in the form of a wire cylinder; in its compressed state, the stent is delivered to the site of narrowing, where it expands and holds the vessel walls in an opened state.
