The pain can come in waves of muscle cramping in the thigh and the upper calf, and sometimes there is discomfort in the feet at night or while sitting: Patients with peripheral artery disease, also known as hardening of the arteries that lead to the extremities, face not only an impaired quality of life, but also a higher risk for heart attack and stroke. While there are surgical treatment options that can improve the condition, there is often a need for a followup procedure if the artery becomes blocked again.
Sunnybrook is one of the first centres in Canada to offer a new therapy option that reduces the need for subsequent surgery. Dr. Andrew Dueck, division head of vascular surgery at Sunnybrook, says a new drug-coated balloon angioplasty restores blood flow and delivers a drug directly into the wall of the artery. The drug minimizes scar tissue formation, which can lead to blockage of the artery and a return of symptoms. For patients, this means a reduction in pain and discomfort, a lower risk of heart attack and stroke, and less chance of more surgery.
That’s reassuring news for the estimated 800,000 Canadians living with peripheral artery disease.
