Know Your Alternatives to Lower Leg Amputation – Diabetes Daily

By Dr. Albert Chun, MD MBA, Managing Physician at Modern VascularNot long ago, a man, only 49 years old, was referred to us; he had already lost toes to amputation and just a week earlier, he was told he was also facing the amputation of his lower leg. He kept his leg, and today he is walking around, driving his car, and living his life in a way that the would have affected greatly.This man was suffering from Peripheral Artery Disease (PAD), a circulatory ailment that affects as many as 12 million Americans; type 2 diabetes is one of the leading risk factors for PAD. This man’s story is not an isolated one; we see many just like this every month. What saved his leg was a minimally invasive outpatient procedure that is becoming a standard treatment option for PAD sufferers and their physicians to consider.What Is PAD?September is PAD Awareness Month, and while we have had much success saving limbs and restoring hope to hundreds of PAD sufferers, we still have work to do to raise awareness of this solution. What is PAD, specifically? It is the narrowing of peripheral arteries due to atherosclerosis (plaque buildup on arterial walls), decreasing blood flow to legs, feet, and toes. Left untreated, PAD complications include critical limb ischemia, gangrene, and amputation.Aside from type 2 diabetes, risk factors that greatly increase the likelihood of developing PAD include increasing age, obesity, high blood pressure, high cholesterol, and smoking. In addition, PAD is more prevalent in African American and Native American populations.Treatment: An Alternative to AmputationWhile many PAD cases have traditionally resulted in amputation below the knee, new therapies are preventing that, giving patients a pathway that keeps them whole. Interventional Radiology is a minimally invasive, image-guided endoscopic procedure to treat vascular disease, down to the toe. These treatments pose minimal risk to the patient, reduce recovery time and lower costs versus Open Vascular Surgery. Who performs these procedures? Interventional Radiologists are medical doctors with 6 or 7 years of additional training following medical school. We are certified in both Diagnostic Radiology and Endovascular Procedures.Endovascular Procedures differ from Open Vascular Surgeries in the following ways:They are conducted in dedicated out-patient clinics rather than in a hospital settingThe procedures are minimally invasive procedures, vs open surgery performed by Vascular SurgeonsThey tend to be shorter and have reduced recovery time, usually discharging the patient on the same dayThey use moderate sedation or local anesthesia of patients while Open Vascular Surgeries often require general anesthesiaBoth Interventional Radiologists and Vascular Surgeons have long-term patient relationships and will continue to see patients for follow-up care after treatment. Modern Vascular patients may follow up with their Interventional Radiology physician for follow up care 2-4 times per year.A glance inside one of the procedure rooms | Photo credit: Dr. Albert Chun, M.D., M.B.A.What You Should DoFor anyone at risk, particularly those with type 2 diabetes, there are a number of things you can do:The ADA recommends that if you have diabetes and you are over 50, you should proactively get a screening test, such as a pulse check or ultrasound, to monitor for problems early.Have periodic foot care at least once a year, to ensure you are not developing ulcers; often, people with diabetes will suffer from ulcers or other lower leg injuries without feeling them, and will not catch them until it’s too late- sometimes weeks later.If PAD symptoms worsen to the point that amputation is recommended, ask your doctor about Interventional Radiology as an option.There is a role for active surveillance for people in all risk categories, but people with type 2 diabetes, in particular, should be vigilant for symptoms. The good news is that if PAD symptoms do arise, there are real alternatives to amputation. For many, like the 49-year-old man I described above, PAD is not the end of life as they knew it – not anymore.About the AuthorDr. Albert Chun, MD MBA, is a Vascular Interventional Radiologist and the Managing Physician at Modern Vascular in Fairfax.
