Surgical Options in Peripheral Vascular DiseaseAnton Sharapov, MD, FRCS(C) Peripheral vascular disease (PVD) is a common condition that affects virtually every vessel in the body. Vessels supplying the brain, heart and lower extremities are most commonly affected. PVD is one of several manifestations of atherosclerosis
Thickening and ulceration on the interior surface of the blood vessel leads to reduced blood supply, which eventually progresses to cessation of blood flow through the affected vessel. This may happen suddenly when a blood clot forms on the ulcerated surface of the vessel wall or gradually, as a result of the thickening of the blood vessel wall. In the end, that portion of the body supplied by the affected vessel will be at risk for damage, with devastating consequences stroke, heart attack, or limb loss. PVD affects virtually every vessel in the body. In order to be successful in managing this condition, one can’t simply concentrate on the heart, leg, or brain blood vessels, but must address all at once. The disease process is gradual. If detected early, treatment, including diet, medications to reduce blood clotting and fat and cholesterol level, blood pressure and diabetes management and lifestyle modifications may change the course of the disease and avert its consequences. Most patients with claudication crampy calves and thighs - can be treated with life style changes and medication. Sometimes the disease progresses to the point when more dramatic intervention may be required such as in limb-threatening ischemia (a restriction in blood flow) or when symptoms prohibit a patient from working. If aggressive treatment and exercise have failed to bring about desired results, the traditional course of treatment is open vascular bypass surgery. The obstructed portion of the circulation is bypassed with either a transplanted vein or artery to bring the blood flow to the affected organ. However, open vascular bypass surgery does place certain stress on the body. The surgery:
Research has shown that when open bypasses are done in hospitals with experienced vascular specialist teams including nurses, family doctors, anesthesiologists, cardiologists, internists and vascular surgeons the overall rate of complications is acceptably low. One of the most exciting areas in vascular medicine has been the development of a minimally invasive alternative to open vascular bypasses. Subintimal angioplasty (SIA) is one of several techniques at the disposal of the vascular specialist to restore the affected circulation. Through careful manipulation of micro guide-wires, catheters and balloons, a new channel for blood flow is created in the existing vessel. |
