Acute management of thromboembolic stroke has undergone a paradigm shift in the last decade with the advent of intra-arterial delivery of thrombolytics. However, this area remains the domain of neuroradiologists. A handful of neurosurgeons and a very small number of cardiologists are performing such advanced neuro-rescue therapies. The window of time to treat patients with acute thromboembolic stroke can be extended if such therapies are more widely available. Vascular specialists in the next decade should focus on increasing training sites for neurovascular interventions. Such advances in neuro intervention by a wider circle of skilled physicians can reduce the morbidity and mortality associated with stroke. The nuances of such radical measures are interventionists attempting to perform stroke therapy. The nuances of such radical measures are interventionists attempting to perform neuro-coiling for aneurysm or arterio-venous malformation.

Our humble opinion is that vascular specialists should focus on learning cerebral arterial anatomy, the natural history and pathophysiology of stroke, imagining modalities to diagnose stroke, pharmacotherapy, hemodynamic management, building a multidisciplinary stroke service and providing dedicated training in the delivery of thrombolytics at the site of cerebral occlusion. Furthermore, proficiency in recognizing and management of complications is essential.

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.
