Endovascular Techniques
As pioneers of endovascular therapy for treating the entire spectrum of vascular disorders, interventional radiologists are doctors who are especially suited to providing solutions to difficult clinical problems which would otherwise require more invasive or complicated therapy. Our current technology for treating vascular conditions includes not only the balloons and stents described above, but also special "covered" stents to seal off defects in blood vessels, materials known as embolics which block off abnormal openings or tears in blood vessels, and devices which suck out blood clots from arteries and veins. A combination of these technologies may be needed in challenging cases, such as the one illustrated below.
Endovascular Repair of Renal Artery Aneurysm
Rotational 3D-angiogram in a middle aged woman with hypertension and an aneurysm of the right renal artery. Treatment of the aneurysm would have traditionally required removal of the entire kidney since performing a surgical bypass around the aneurysm would have been limited by a lack of sufficient renal artery beyond the aneurysm.
Rotational 3D-angiogram following endovascular repair of the aneurysm by NYU interventional radiologists. A stent was placed across the "neck" of the aneurysm to provide a scaffold to "pack" the aneurysm sac with special metal coils to seal off the aneurysm while preserving the blood flow to the kidney. This was performed through a tiny nick in the skin near the groin and the patient was discharged home the following morning.
