CryoPlasty (sometimes called cryo-balloon angioplasty) is a new type of therapy for peripheral vascular disease. Clogged or narrowed arteries can be opened using this new type of vascular therapy that cools and dilates the vessel at the same time.

The technique is very similar to angioplasty procedures used in heart vessels, except stents are not used to keep the blood vessel open.

In CryoPlasty, a balloon is filled with liquid nitrous oxide, which evaporates into a gas upon entering the balloon, causing it to dilate and cool to -100C (140F). The plaque clogging the artery cracks when it freezes, allowing for a more uniform dilation of the blood vessel than occurs in a standard angioplasty.

Surgical treatment involves placement of bypasses by using a graft. A graft is a portion of one of the veins or a man-made synthetic tube that the surgeon connects above and below the blockage. A surgeon plans these interventions on the basis of 3D images obtained from MRI or CT scans.

Aneurysm
Aneurysm is a common condition that requires surgery. It is a bulge (dilation) in the wall of an artery, usually the aorta, but can develop in any artery. Aneurysms that are wider than about 2½ inches (6 centimeters) rupture fairly commonly, & hence need surgery. Surgery consists of inserting a synthetic graft to repair the aneurysm.

Varicose veins
Varicose veins are enlarged, swollen vessels that need surgical intervention. Their treatment involves Ambulatory Phlebectomy, a minimally invasive surgical technique. The abnormal vein is removed through a tiny incision or incisions using a special set of tools. Sclerotherapy involves a series of injections of medication into the veins. When injected into the vein, the medications irritate the lining of the vein, making it sticky, the vein is then compressed with large pads to make the vein walls stick together. A thigh-high compression stocking is applied to each treated leg after the injections.
