The vexing problems of critical limb ischemia (CLI) are on the rise globally due to several factors such as increased life expectancy among elderly patients, an increase in the prevalence of diabetes mellitus, exponential growth of cardiovascular disease burden and patients’ increasingly sedentary lifestyle. So what is new in terms of management and treatment of CLI?

1. Increased awareness of CLI among providers from doctors to wound-care clinics;

2. Advances in management of tibio-peroneal lesions such as the use of chronic total occlusion devices, use of drug-eluting balloons and drug-eluting stents;

3. Advanced medical management measures such as risk-factor reduction with the use of aspirin, renin angiotensin-blocking agents and statins, wound-care clinics to provide hyperbaric oxygen therapy, debridement and monitoring;

4. Clinical trials aimed at salvage treatment such as cell therapy are at bare minimum due to economical constraints;

5. Increased use of multispecialty efforts to treat patients with CLI and reduce amputations.

ROBERT S. DIETER, MD, RVT
Dr. Dieter is an interventional cardiologist and vascular medicine specialist. He has completed advanced fellowship in Vascular Medicine and Peripheral Vascular Interventions at Georgetown University/Washington Hospital Center in Washington, D.C.

With a patient care emphasis in Vascular Medicine, he specializes in the management of patients with complex vascular diseases. He manages patients with stroke, TIA, and those at risk for stroke, particularly those with carotid artery blockages requiring angioplasty/stenting or those with PFO. He also specializes in renal artery stenosis. In fact, Dr. Dieter has published on new and potentially safer methods to treat blockages in the renal arteries. Dr. Dieter performs minimally invasive abdominal aortic aneurysm repair (endograft). Dr. Dieter has extensive training in the management of patients with claudication, as well as those with critical limb ischemia and non-healing ulcers — particularly in patients with diabetes. Furthermore, Dr. Dieter is board-certified in interventional cardiology and specializes in angioplasty, stenting and myocardial infarction treatment. Although Dr. Dieter is a vascular medicine specialist and interventional cardiologist, his underlying philosophy is the prevention of disease. He completed an advanced fellowship with renowned experts in Preventive Cardiology. Dr. Dieter actively treats patients with complex dyslipidemias.

Dr. Dieter graduated Alpha Omega Alpha from medical school. He has written over 100 journal articles, eight book chapters, is on the editorial board of several medical journals, and lectures internationally on cardiovascular diseases. He is the editor of two textbooks on vascular disease.
