Two techniques are available for endovascular treatment of post-SAH vasospasm: mechanical angioplasty and phamacologic infusion(papaverine or other vasodilator). The advantages of papaverine infusion are simplicity, safety, and the ability to reach small distal vessels. The disadvantages are that the treatment results may be temporary and inconsistant. The advantages of balloon angioplasty are rapid, dramatic result and consistantly successful. It is important to treat vasospasm as soon as possible for two reasons: vascular response is better and permanant ischemic damage is minimized. If ischemic symptom have developed, it may already to be late. So, the treatment of vasospasm should be proreactive rather than reactive.

Endovascular treatment has rapidly progressed due to the improvements of the equipment and endovascular devices. Continual refinement of the technology and techniques associated with endovascular treatment has led interventionists to perform more complicated endovascular treatment. However, the numerous complications of endovascular treatment are now well recognized and described in the literature. This article reviews various complications of three main endovascular treatments: balloon angioplasty, stent or stent-graft placement, and catheter-directed thrombolysis.

Coronary pseudo-lesion is an artificial lesion that occurs during percutaneous transluminal coronary angioplasty by an angioplasty guide wire and/or a balloon as a result of a straightening of the vessel curvature. A specific treatment is not required and the condition is completely resolved after removing the angioplasty wire. There are few reports about a pseudo-lesion, particularly in the left circumflex artery. We report two cases of a coronary pseudo-lesion induced by an angioplasty guide wire; one case affecting the left circumflex artery and the other affecting the right coronary artery.

We report our experience in coronary angioplasty and intravascular ultrasonography (IVUS) on a heavy, encircling, calcified lesion that was not dilated with the use of a cutting balloon and a non-compliant balloon. The angioplasty was successfully performed with a simple and inexpensive hugging balloon technique.
